I opened up my browser and all my active tabs which I have had for months are gone. I tried to go to recently closed tabs in history and it doesn't allow me to open. All are not available. Help!!

Within the last hour or so, I needed to close Firefox while installing an app (the setup was recommending to close all Windows programs).

Had 8 windows open.

Right-clicked on the Taskbar Firefox icon, then selected the option "close all windows" - it proceeds to close each window consecutively, asking me each time for manual confirmation whether to close this window with x tabs in it - and I just confirm each time.

So then after that setup is completed, I open Firefox again - the last closed window is restored (as per the settings);

then I click on History, "recently closed windows", and.... there's only 2 windows on that list. I restore those 2, and then the list is empty - nothing more to restore.

So if I had restarted the PC, it would've just restored the 8 windows upon reopening Firefox, as usual - but since I opted to just close Firefox like this, "close all windows", I just lost 5 windows.

So could anything be done here?

Something in the files? Maybe the C:\Users[user]\AppData\Roaming\Mozilla\Firefox\Profiles\4qu1kfr9.default-release\sessionstore-backups path? There's a file called "previous.jsonlz4" in there, something I could do with that one?

Or something else?

Any help would be appreciated!

My tabs keep disappearing and I have to restart manually. I used to go to the 3 bar menu and select Restore previous session but now it doesn't appear in the menu.

What else can I do to identify the problem? I've taken the following actions: Restarted the app, refreshed then reset the app, ran troubleshooter mode, uninstalled then reinstalled the app, re-booted my PC and shut down-rebooted my PC, disabled all protections in Bitdefender(firewall, ransom, etc), ran a full anti-virus scan, checked Chrome and Edge(they work fine), created a 2nd profile but no change. My system consists of the following: ASUS Z390-a MB I5-9400 CPU 64GB of RAM 850W ATX PSU Intel 1TB SSD(OS) Windows 11 Pro I believe this problem started soon after I updated the BIOS on my ASUS MB. I'm not sure how that relates. Thanks for any help or suggestions. optimxr PS the message on the tab is "GAH, Your Tab Just Crashed"

Hello, Please tell me how to remove the tab on the far left of the photo. I can close tabs, but this one is permanent. It is there whenever I open up Firefox.

How did I even put it there? Thank you

I have a problem where after restoring session in FF it makes me unable to drag and move tabs around at all. I tried to start FF in safe mode to see if it was one of the extensions causing it, but that didn't stop it. I noticed that the last time this happened not that long ago it sorted itself out after a while and i regained the ability to move tabs around again, although i still don't know how/why it got sorted out the first time. So i hope someone here could maybe help me a bit.

I am using windows 7 (with the latest update i believe) and updated FF to the latest available version.

Firefox continues to add a new tab during navigation on a website. Every selection adds a new tab rather than staying within the original tab. Trying to sign out from a website is problematic because a new tab is added which is blank and the original remains signed in. How can this be changed?

I am using Firefox 114.0.2 address bar only, no search bar. I do not remember when it was happened, but today when I want to copy and paste page address I found out that address bar did not display the page address as previous version, just display the words I searched as a search bar (if the search bar is enabled, and typed in search bar then push enter, address bar will display address of search result page, and search bar will keep displaying the words in it). I attached my screenshot below. Using another tab and "switch to tab" feature by Firefox, I found out the page address. In my screenshot, I typed "test" and using Google to search (I also tried Bing, Wikipedia and more and all of them have the same problem with their owned link) and the page address should be "https://www.google.com/search?client=firefox-b-1-d&q=test" but even I paste this link into the address bar, it will only display "test" like the pic. I think it is a trim feature but I do not which preference I should edit in about:config. I have set "browser.urlbar.trimURLs" to false for displaying http and www, but it is not work this time.

How do I tell firefox's tab key not to go to links, only form fields. That is, if you go to https://visca.com/apac/dites/, hitting 'tab' should take you to the form field [Cerca], whereas now it scrolls through all the links first.

Thanks in advance, Lou

The updating to the latest edition of Firefox caused all my open tabs to be lost. There is nothing showing up in "History" and no text links to click on to restore any of the tabs I had from the previous session. This makes me want to never again update Firefox because updating means losing all the open tabs that existed in the previous session before the update. This is a major browser bug that you should repair because this bug really tarnishes the reputation of Firefox browser.

So a while back (maybe a year already idk) there was once an update and ever since then i had a pinned tab (a tab that only is an icon?) in the upper left corner that was a sort of a home page of fire fox. Not the usual home page but a place that had like history and stuff. I lost it accidentally and would like to get it back. Does anyone know how?

bold textI did safety mode, did a reset, and still, when I click a hot link, I don't get a new window or a new tab as I directed in settings. WTF?

In Firefox 114.0.2, the tab foreground color for most NYTimes.com pages initially is black, but after an instant, the foreground color now becomes gray. The background color is a similar gray, so the tab symbol for the NYTimes (beginning with an ornate letter T) cannot be distinguished from the background. The NYTimes tab foreground color used to remain black.

For an example, go to https://www.nytimes.com/. The tab foreground colors for some NYTimes pages remain black; for example, go to https://help.nytimes.com/hc/en-us. I think this tab foreground color change began recently, less than a month ago. This problem does not occur for web sites other than the NYTimes. Restarting my computer does not help. This tab color problem does not occur in Edge or Chrome.

Thanks for any info
