Hey there,

during work I often open two windows of Firefox to have more information visible on my two monitors. Unfortunately I sometimes forget that I have a second window open, so I close only my "main" window and loose all tabs.

Is there a way to force Firefox to ask to close a window and loosing multiple tabs for every window open?

Right now this only happens for the last open window.

PS: I just found out about the keyboard shortcut of restoring a window (CTRL+SHIFT+N) recently. I would prefer a setting in my case.

Thanks in advance Fred

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

Everytime I try to open a tab on my Firefox window, it loads for a second before a blank screen saying that my tab has crashed. The only times I can open a new tab is on a private window.

When I logged onto Firefox this morning it asked me to update which I did. When I got onto Firefox all my tabs were gone. Please tell me if I did something to cause this and how to keep this from happening again. I do have it set up to restore tabs when logged off and starting up again. Also please tell me how to get my tabs back! I tried to follow instructions for this but actually didn't have the things they said to click on. Thanks so much for your 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!

I have updated to the latest version of Firefox browser this time. Whenever I create a new tab, the page will prompt me with a failure to load content and hope me to try refreshing to resolve it, but it does not work

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

"Container Tabs" are unavailable in Firefox on my employer's corporate PC. The "Enable Container Tabs" option is missing in the Tab section in Settings. There is a notification "Your browser is being managed by your organization." Thus, the lack of container tabs may be due to corporate policy. However, I don't see anything on the Active Policies page except one irrelevant record: "InstallAddonsPermission Default false." Additionally, "Container Tabs" are unavailable only in Firefox. Nightly has them. But, Nightly is not officially supported by my company. I have tested several corporate PC and different versions of Firefox and Nightly. Is it a weird Firefox bug or something else?

I need to shrink the size of my tabs, which remains constant no matter how many are open. If I have four open, I get the "+" for a new tab at the end of the tab bar. If there are five open, the tabs consume the entire width of the browser window and the "+" sign disappears. It is not found in the "customize toolbar" menu. I have tried restoring tool bar defaults and changing the uidensity to 1, but neither change shrinks the size of the tabs or gives me the "+" option.

What do I need to do to get back to the way it used to work?

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

I need pinned tabs to show their title, just like normal tabs. They currently only show an icon, but apart from the fact that in my case the icons are identical to one another so I can't know which one is which without hovering them, I'm more of a text person anyway.

So, how to make pinned tabs show their title?

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

I use the Feedbro-Addon, which creates an own tab. Its url is: moz-extension://285d678c-ecb3-4003-923d-835fc9d8e0bc/reader.html

If I use it as a normal tab (instead of a pinned tab) ... it survives a Firefox restart. But if I use it as a pinned tab (which I want) ... it disappears after a Firefox restart.

I suppose it has to do with it being an addon-page instead of a "normal" page.

Is there a way to make it stay permanently pinned?

My old hard drive died I couldn't recover it. I cannot mount the disk to another OS etc. The session files cannot be retrived. However I had over 100 tabs open in Firefox I want to retrieve before the disk crashed. I was signed in to firefox all the time in the old computer.

I now have a new computer, I signed in to firefox and I can recover the bookmarks. But I don't see any option to recover the lots of tabs and sessions from my previous dead disk. It seems there is tab sync options between 2 devices that is concurrently signed in. But I can't sign in to a dead disk. I also can't recover the file.

How can I reteive my old sessions with many tabs? I'm hoping firefox have a way of knowing all my tabs since I was signed in and sync before the disk crash.

Hello, I am using Firefox on a new computer, and I have a bizarre problem that I never experienced on other computers. The 'recently closed tabs' and 'recently closed windows' options are disabled. They are grey, and I can't click them (see image). Also, the 'reopen closed tab' when you right-click one of the tabs is disabled (grey). I have tried to search everywhere why it can happen and found nothing. Any advice on how to enable this option? Thanks

If you have multiple tabs open and you hit Ctrl-T to open a new one, it opens it at the end of the tabs, and the cursor focus moves to the URL bar so you can start typing in an address/search.

If you right-click on any of those tabs, it opens a new tab to the right of that tab, instead of at the end (which is what I want, as right-clicking on a specific one to open a new tab, to me, means you are linking those tabs in layout and want them together) BUT the cursor focus DOES NOT move to the URL bar.

This seems pretty counter-intuitive, and means that so many times I right-click, Open New Tab, and start typing a URL and then see that I have to stop typing, click in the URL bar, and start typing all over again.

Is there an about:config to force the focus to the URL bar, or is this a bug? If there's no setting for this, I would definitely consider this a bug because you have 2 different behaviors for New Tabs.

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

Youtube not working in a new tab when I open a link on a new tab from youtube. The Shorts are working fine. Both videos and shorts are working on chrome but not on mozilla.

'After last update, the new tab option does not offer either a selection of most visited sites or recent sites despite that both are check on in the settings. How can I turn on that function again?

By mistake, I close a window with lots of opened tabs and can not get them back. In the past when this happened I went to history but now there's no available option in "recently closed windows".
