All my tabs (I think they're tabs - on the menu bar just below the main menu at the top left of the home screen - have disappeared. I checked history, hoping to replace them and the returned. But now they've vanished again. Also, when FF opens, email screen displayed is 'primary' and it says there are no primary messages. I've always used 'all mail' so I go to that site (which is in a folder on the menu which is below the address bar) and click on it to get to mail.

How can I restore the missing tabs which were on the menu bar just above the address bar?

Many thanks.

when i booted up my laptop this morning i notice all of my tab groups were gone. i know how to get to where the tab groups are held, but when i click on the down arrow thing none of my saved tab groups appear. is there any way i can get them back? i used them for art references so theyre pretty important to me

Last week I downloaded the latest update for Firefox. After that I could not open websites I often use, such as etsy.com and ebay.com where I sell items. Also could not connect to Firefox Support. Yesterday, 4/19/2026 I uninstalled and reinstalled Firefox. I have box selected to open new tabs instead of new window, however, when I click on a line from my email it opens new window which causes me to have to sign-in to my accounts again, multiple times today. Also, after the latest update I cannot use my main modem network, have to use another wifi network. Also a couple of times today when I open a tab it is trying to use the primary network and pages will not load. I need help in resolving issues caused from last weeks update. I know this is very long but felt I need to tell you what is happening so you'd better understand steps to take to resolve issues. Thanks for your help.

So frustrating. Been a Firefox user for nearly two decades and this is first ongoing issue I have not been able to fix . . .

I work with 7-10 open tabs at any given time. Whenever I close a tab, my entire browser shifts and resizes. It's quite disruptive.

I've gone into AI and done some config troubleshooting, but nothing working.

after the last update which was very nice btw.. I get two windows pop up of fiirefox browser with my remembered tabs. I added all to just one browser window and for a while it was fine. Now again two windows with different tabs are popping up when I restart the computer. how do I remove one of them

I've been trying to decipher browser.tabs.insertXXX with little success. What I want to achieve is to open tabs from the same site next to the current tab with the most recently opened tab next to the original tab.

Example Two tabs are open, site 1 tab 1 and site 2 tab 1. Open a new link to site 1 on site 1 tab 1. The order is site 1 tab 1, site 1 tab 2, site 2 tab1. Open another link to site 1 on site 1 tab 1. The order is now site 1 tab 1, site 1 tab 3, site 1 tab 2, site 2 tab 1.

Thanks in advance.

I've recently come across the issue stated in the title. I've turned the setting off and on again, tried with the setting on and off, and it keeps automatically swapping to the new tab 95% of the time. There are a couple times that it wont swap but it more than certainly happens on the 2nd try. I believe this started happening after update 148 was installed.

Hi there,

is this a bug or did I do/get something wrong? ( I relied on https://support.mozilla.org/de/kb/tab-gruppen-in-firefox )

As there is the option, to "save and close" a tab-group, I thought it would be possible to acces the group again, after closing. This seemed to be the case, as clicking on the often looked for little "v"-button next to the tabs, provided me not only with a list of my open tab-groups but also with the menuepoint "closed groups", clicking on which, the closed groups were listed. I was happy about the tool and started to use it quite intensely, creating more than 10 closed groups, to which I could add additional tabs, although the groups were closed.

Well, so far so good, yesterday I found out, that "close and save" is not really saved? It just doesn't have "Closed groups" (geschlossene Gruppen) anymore.

Is that behavior according to plan (not mine, but the developers one) Is there any way I could get the closed groups and/or the tabs in them back?

Thank you. Svenja

When using vertical tabs layout with "expand sidebar on hover" setting enabled, sidebar scrolls up with each expansion, so that when hovering over a certain tab of collapsed sidebar, another open tab is under the mouse pointer when expanded. For additional details please refer to the attached video.

Steps to reproduce: 1. Enable vertical tabs layout with "expand sidebar on hover" setting 2. Open a lot of tabs 3. Hover over a certain tab

Observed result: The sidebar expands with mouse over another tab and the list of tabs scrolled up.

Expected result: The sidebar expands and mouse pointer is hovering over the same tab after expansion from collapsed state.

I cannot add much to the description. I'll make the comment that having to look into the history to find a tab supposedly at hand is inefficient and a waste of time.

when i open my firefox, all of my previous opened tabs goes blank and only 1 rightmost recent tab can be open, that was my last night tab,next i close firefox and open again and my tabs its all gone

I recently refreshed my FF installation. Before I did that I had configured my tab settings to always display the x icon (close tab) in all active tabs. After the refresh, the x icon is gone for all tabs.

I cannot remember what I did to get them to display originally. I've tried to do this in the userchrome.css file. But it didn't work. Let me know if you have a solution.

Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

Hello. I have issue with Firefox. I am often opening firefox by command: firefox --no-remote -P <profil> --new-window "<web_site>" Usualy it works. But sometimes it is opening new window and my web_site is located in second tab. First tab (which is completelly unwated) start loading after clicking on it. It is a recently closed tab. I call this tab zombie-tab. It was finished and properly closed, however it rose from the dead. I tried to set in about:config browser.sessionstore lot of parameter to absolutelly forbid to save any information. However, there is still whole history in the list, sites are restorable and sometimes it appears these zombie-tabs. Restore from crash is also deactivated. I tried before to start the firefox without --no-remote parameter, but AI recommend me to add it there. It did not help. Since it is happening occasionally, I consider it as a bug. Some my settings: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0 browser.sessionstore.resume_from_crash = 0 browser.sessionstore.cleanup.forget_closed_after = 149 Version: 140.7.0esr (64-bita) OS: Debian GNU/Linux 12 (bookworm) How to prevent to create zombie-tabs?

Steps that remove my pinned tabs from Firefox:

Open pinned web app from taskbar. Open regular Firefox browser.

Any pinned tabs that were in the browser before opening the web app are lost.

Is this already reported? I can't imagine this is intended behavior.
