If one browser keeps reopening the same old tabs every time you start your Windows computer, the problem can be surprisingly confusing.
You may close the browser normally at night, shut down Windows, and then find the same collection of tabs waiting for you the next morning.
The first thing to understand is that browser startup and Windows startup are not necessarily the same thing.
A browser can reopen old tabs because its own startup setting is configured to restore the previous session. Windows can also restart applications after you sign back in. An extension, startup entry, or browser-specific setting can create another version of the same behavior.
The safest solution is to determine which mechanism is reopening the browser before changing several settings at once.
First, Determine What Is Actually Happening
Start by asking a simple question:
Does the browser open automatically when you sign in to Windows, or do the old tabs appear only after you manually open the browser?
These are two different problems.
If the browser opens automatically as soon as Windows starts, investigate Windows startup and the browser’s automatic-launch behavior.
If the browser stays closed until you click its icon, but then immediately restores your previous tabs, investigate the browser’s startup or session-restore setting.
This distinction can save you from changing settings that have nothing to do with the problem.
Check the Browser’s Startup Setting First
Most major browsers have a setting that controls what happens when the browser starts.
A common option is something similar to:
Continue where you left off
When enabled, the browser is designed to reopen the pages that were open during the previous session.
That feature is useful when you want to continue working where you stopped, but it becomes annoying if you want a clean browser window every time.
If you want the browser to stop restoring old tabs, change its startup behavior to an option such as:
Open the New Tab page
The exact wording and location can vary between browsers and versions.
Stop Chrome From Restoring Previous Tabs
If the affected browser is Google Chrome, open Chrome and select:
Three dots > Settings > On startup
Look for:
Continue where you left off
If that option is selected, Chrome is configured to reopen the pages from the previous session. Google’s current Chrome documentation confirms that this setting controls whether Chrome reopens the same pages that were open when you quit.
To stop this behavior, choose:
Open the New Tab page
instead.
You can also choose Open a specific page or pages if you want Chrome to open particular websites rather than your previous session.
Test the Change
Do not immediately restart Windows.
First close Chrome completely.
Then open Chrome again manually.
If the old tabs no longer appear, the browser’s session-restore setting was probably responsible.
If the old tabs return even though Chrome is configured not to continue where you left off, continue investigating.
Stop Firefox From Restoring Previous Windows and Tabs
Firefox has a similar setting.
Open Firefox and go to:
Settings > General
Look under the Startup section.
Firefox provides an option called:
Open previous windows and tabs
When enabled, Firefox can restore the windows and tabs from the previous session every time the browser starts. Mozilla’s current support documentation confirms this behavior and the location of the setting.
If you want Firefox to start cleanly, turn off:
Open previous windows and tabs
Then close Firefox and launch it again to test the change.
Check Microsoft Edge
Microsoft Edge also has startup behavior that determines what appears when the browser opens.
Open:
Edge > Settings
Then look for the startup section, where Edge allows you to control what the browser displays when it starts. Microsoft’s documentation identifies Start, home, and new tab page as the area for controlling startup behavior.
If Edge is configured to restore the previous browsing session, change the startup option to the behavior you actually want.
The wording may vary slightly depending on the current Edge version.
What If the Browser Opens Automatically With Windows?
This is a different situation.
Suppose you shut down your computer with Chrome closed.
The next morning you sign into Windows and Chrome launches automatically with yesterday’s tabs.
In this case, changing Chrome’s normal startup page may not be enough.
Windows itself may be restoring the application when you sign in.
Windows has a setting related to automatically saving restartable applications and restoring them when you sign in.
On supported Windows configurations, go to:
Settings > Accounts > Sign-in options
Look for:
Automatically save my restartable apps and restart them when I sign in
If this is enabled, Windows can restore applications after sign-in rather than treating the next session as a completely fresh launch.
Microsoft specifically documents this setting as a way to control automatic application restoration at Windows sign-in.
If your problem is that the browser launches by itself after signing into Windows, this setting is worth checking.
Check Windows Startup Apps
Another possibility is that the browser has been added to Windows startup.
Open:
Settings > Apps > Startup
Look for the affected browser.
You can also check startup applications through Task Manager.
If the browser is enabled there, Windows can launch it when you sign in.
Do not disable random startup applications simply because they appear in the list.
The goal is to test the browser that is actually causing the problem.
Disable its startup entry, restart Windows, and see whether the browser still opens automatically.
If it stays closed until you manually launch it, you have narrowed down the cause.
Do Not Confuse Browser Startup With Startup Websites
There is another detail that can make this problem confusing.
A browser may be configured to open specific websites when it starts.
For example, Chrome allows you to choose Open a specific page or set of pages.
If you see the same websites every time, check whether those pages are explicitly configured as startup pages.
This is different from restoring a previous session.
How to Tell the Difference
If the browser opens exactly the same set of pages every time, check its configured startup pages.
If it opens whatever tabs happened to be open when you last used it, session restoration is a more likely explanation.
That distinction is useful because changing the wrong setting will not solve the problem.
Check Whether You Are Closing the Browser Completely
The way you close the browser can also affect what happens during the next launch.
If you have several browser windows open, make sure you understand whether you are closing the entire browser or only one window.
For troubleshooting, close all browser windows completely and then start the browser again.
If the browser continues to restore an earlier session even after you have changed its startup behavior, move on to extensions and Windows startup.
Do not keep repeatedly closing and reopening the browser without changing anything. That makes it harder to determine what fixed the problem.
Check Browser Extensions
If the browser’s startup settings look correct but unwanted pages still appear, investigate extensions.
An extension can alter browser behavior, including startup pages, new tabs, redirects, or other browsing settings.
Open the browser’s extension management page.
For Chrome, you can enter:
chrome://extensions/
Review the installed extensions.
Look for anything you do not recognize or did not intentionally install.
Do not remove every extension at once.
If you remove several simultaneously, you will not know which one was responsible.
Instead, start with extensions that were recently installed or that you do not recognize.
Then restart the browser and test again.
If the problem disappears, you have a much stronger indication that an extension was involved.
Pay Attention to One Specific Website
There is an important difference between:
“My old tabs keep returning.”
and
“One strange website keeps opening.”
If the browser restores the exact tabs you previously had open, session restoration is a strong suspect.
If an unfamiliar website appears every time even when you did not previously have it open, investigate startup pages, extensions, and potentially unwanted software.
Chrome’s support community has recent reports of unwanted startup websites being connected to startup settings or extensions, although community guidance should be treated as troubleshooting advice rather than official documentation.
If you see a website you do not recognize, do not sign in or enter personal information simply because the page opens automatically.
Check the Browser Shortcut
A less common possibility is that the browser shortcut itself has been modified.
This is particularly worth checking if only one shortcut behaves differently from the browser when launched another way.
Right-click the browser shortcut and select:
Properties
Look at the Target field.
Normally, the target should point to the browser’s executable.
If you see an unexpected website address or unfamiliar command-line text after the normal executable path, do not simply delete it without understanding what it is.
Compare the shortcut with an official shortcut created by the browser or use another legitimate launch method to test whether the behavior changes.
If a shortcut appears suspicious, investigate the cause rather than assuming the shortcut is the only problem.
Check Whether Windows Is Restoring the Browser After an Unexpected Shutdown
There is another situation worth considering.
If Windows did not shut down normally because of a crash, forced restart, power failure, or other interruption, the browser may attempt to recover the previous browsing session.
This is different from deliberately configuring the browser to restore tabs every time.
To test the difference, close the browser normally.
Then reopen it manually.
If it restores the old session only after an unexpected shutdown but starts normally after a clean close, session recovery may be involved rather than a Windows startup problem.
Do not repeatedly force Windows to shut down just to test this.
A normal shutdown is safer.
If Only One Browser Does It
The fact that only one browser behaves this way is useful evidence.
If Chrome keeps restoring tabs while Firefox and Edge do not, there is probably no reason to change general Windows settings first.
Start with Chrome’s startup and extension settings.
If Firefox is the only browser doing it, start with Firefox’s startup settings.
If Edge alone is affected, investigate Edge’s startup configuration and Windows’ application restoration behavior.
This is a good example of why diagnosing the scope of a problem first can save time.
What If the Browser Setting Is Already Correct?
Suppose you have checked the browser’s startup settings and they are already configured not to restore old tabs.
Do not immediately reinstall the browser.
Work through the possibilities one at a time.
Check whether:
- Windows is restoring the browser at sign-in.
- The browser is enabled under Startup apps.
- An extension is changing startup behavior.
- A specific startup website is configured.
- The browser shortcut has unusual parameters.
- The browser is recovering an interrupted previous session.
- The browser profile itself has become corrupted.
If the problem began after installing an extension or application, that timing is useful evidence.
It does not prove that the installation caused the problem, but it gives you something specific to investigate.
Create a Controlled Test
A simple test can tell you much more than changing ten settings at once.
First, close the browser completely.
Open it manually.
Check whether old tabs appear.
If they do not, close the browser again.
Then restart Windows.
After signing in, do not click the browser.
Wait and see whether it launches by itself.
If it does, Windows startup or application restoration becomes a stronger suspect.
If it stays closed, manually launch the browser.
If the old tabs now appear, the browser’s own startup or session settings deserve more attention.
This test separates Windows launching the browser from the browser restoring the session.
What Not to Do
Do not immediately delete your browser profile.
Do not remove every extension without testing them individually.
Do not edit Windows Registry entries because a random website says they control browser startup.
Do not install a third-party “browser cleanup” application just to stop old tabs from returning.
Do not repeatedly force-shut down Windows.
And do not assume that seeing yesterday’s tabs means the computer has been compromised.
In many cases, the behavior is simply caused by a browser session-restore feature or Windows’ application-restart behavior.
When the Problem May Need More Investigation
If the browser repeatedly opens unfamiliar websites, changes your search engine, installs extensions you did not add, or returns after you remove its startup settings, investigate the possibility of unwanted software.
If the browser simply restores legitimate tabs that you previously had open, the issue is much more likely to be related to session restoration or startup configuration.
If the behavior started immediately after installing an extension or desktop application, investigate that change first.
If none of these checks explains the behavior, consider creating a fresh browser profile or using the browser’s official repair or reset options, depending on what the browser supports.
Before resetting a browser profile, make sure important bookmarks, passwords, and other data are synchronized or backed up as appropriate.
A Simple Troubleshooting Order
If you want the shortest safe process, use this order:
First: determine whether the browser launches automatically or only restores tabs after you open it.
Second: check the browser’s startup setting.
Third: check Windows’ application-restart setting.
Fourth: check Windows Startup apps.
Fifth: check the browser’s configured startup pages.
Sixth: review extensions.
Seventh: test the browser after a normal Windows restart.
Finally: investigate the browser profile or unwanted software if the behavior continues.
Changing one thing at a time makes the result much easier to understand.
Frequently Asked Questions
Why does my browser keep opening my old tabs?
The most common explanation is a browser setting that restores the previous session. Chrome, Firefox, and other browsers provide session-restoration features that can reopen previous tabs when the browser starts.
Why does the browser open automatically when Windows starts?
Windows can restore certain restartable applications when you sign in, and a browser may also be configured as a startup application. Windows provides settings under Accounts > Sign-in options and Apps > Startup that can help identify this behavior.
Why does Chrome reopen old tabs even after I close it?
Check Chrome > Settings > On startup. If Continue where you left off is enabled, Chrome is specifically configured to restore the previous session.
How do I stop Firefox from reopening previous tabs?
Open Firefox Settings > General and look under Startup. Disable Open previous windows and tabs if you do not want Firefox to restore the previous session.
What if a website I do not recognize keeps opening?
Check the browser’s startup pages and installed extensions first. If the unfamiliar page continues to appear after those settings are corrected, investigate potentially unwanted software and avoid entering personal information into the unfamiliar site.

Conclusion
A browser that keeps reopening old tabs is usually not something that requires drastic Windows changes.
First determine whether Windows is launching the browser automatically or whether the browser is simply restoring its previous session. Then check the browser’s startup setting, Windows application-restart options, Startup apps, configured startup pages, and extensions.
If the problem continues, test one change at a time and look for unfamiliar extensions or websites.
That approach helps you fix the behavior without unnecessarily deleting browser data, changing the Registry, or reinstalling Windows.
