how do I delete a tab group or stop it from opening all tabs eveytime I start firefox?

I never set up a tab group but somehow I have one with three tabs in it and I have gone to the group and clicked on the X in the top right corner but it continues to open every tab in the group every time I open a browser. I don't want ANY of these opened, I don't even want a tab group, how do I delete this group thing and how do I make it stop opening these web pages?

Hi schrader,

What do you have Firefox set to do when it starts? Did you tell it to restore your last session or go to a specific home page?

You should take a look at the Knowledge Base article How to set the home page. There are steps in that article to reset your homepage preferences to default. Then be sure you've set Firefox to show your home page on startup and restart it. I would try that first to clear out any strangeness. If that works, you can try setting your homepage again to your personal preference.

If that doesn't work you should look at the article How to fix preferences that won't save.

Hopefully this helps!

Tools tab (on the top left of the Firefox browser) > options > general > When Firefox starts... > show my home page >

Home page...> set as google.com or another default website you would like to have at startup

Thank-you for your response however, I have NO IDEA what you are talking about. I don't know how to check to see what Firefox is set at upon opening, I didn't change anything, when I click on the Firefox it opens three tabs, none of which are my home page, if I click on it again it will open just one, my home page but I can't get this tab group to go away. I never set any tab group and didn't even know they existed until I tried to open a browser and got the three open tabs, that is when I started looking at the help topics to see what the hell....

So I ask again, how do I delete A tab group?

Sorry, this didn't work either..... My home page has never changed, it is still set, I need to know how to DELETE a tab group.

I think this might do it. However, there may be consequences and be harmful to the stability of the browser.

Type about:config in the address bar and press enter.

Agree that you will be careful. Type in the filter browser.tabs.insertRelatedAfterCurrent in the filter field. You should see a single setting of type boolean. Double-click the browser.tabs.insertRelatedAfterCurrent setting so it toggles and shows false

This should disable not necessarily delete tab grouping.

Hi schrader,

Did you reset the home page as I suggested and then restart Firefox? Also, did you check to see if have told Firefox is set to restore your last session or show your homepage? The reason I ask is that it sounds like you might have a stored session with that tab group that just won't go away. You could try deleting Sessionstore.js from your Profile Folder.

You could also try starting Firefox in Troubleshoot Firefox issues using Safe Mode. Don't worry, NEITHER of these suggestions will hurt your business computer. Just don't delete anything else from the profile folder Smiley Wink

Hopefully this helps!

See also:

Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.

You can use this button to go to the Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Open Containing Folder

Also reset the browser.panorama.experienced_first_run pref on the about:config page via the right-click context menu.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access the about:config page.

  • Use the Filter bar at the top of the about:config page to locate a preference more easily.

Again, I have NOT stored anything, hell I didn't even save these tabs as a group, yes, I looked at the home page, it is still set as it has always been, you keep saying to start it in safe mode, I am not a computer geek and have no idea what that means.

I do NOT need to tell it what my homepage is, I NEED to delete the freaking TABS GROUP! THAT'S ALL!
