I accidentally clicked on the x in private mode. It didn't warn me before closing the many many open tabs in private mode!!!

What the heck?!

Firefox is updated to the latest version that was offered.

I'm using an ancient" machine but that shouldn't matter. If the box is checked to warn me first, then it always should, regardless what operating system or mode I'm in.

Very disappointed. Please fix or advise a solution I might try to prevent something similar in the future.

But I don't know what in the world I could have possibly done differently.

One checkbox being checked that claims to be to receive a warning before closing multiple tabs at once should be enough.

The images or symbols for different websites are not loading in tabs. I have reset several times. I have closed out of the widows and nothing. Is there a fix to have tab images populate normally? I attached a snip of 4 different websites all had images in 2021 and now they will not load.

See attached image. Things I want to be able to do, which were once easily accomplished with Tab Mix Plus. When I type in search bar, open in new tab. When I type in address bar, open in new tab. Have new tab open at far right (be the last tab) so it is easy to locate. Ability to protect pinned tabs to protect them from being accidentally closed. Currently, links still open in new tabs but not bookmarks and history. I'm in over my head. I just don't know how to get things to work the way they once did with Tab Mix Plus and don't know why this wonderful add-on isn't valued by Firefox. Thanks!

If you use userChrome.css to customise the tab toolbar, you might see the height of the tabs increase with Firefox 96.0.2. For me the fix was to add an entry to userChrome.css:

   #tabbrowser-tabs:not([secondarytext-unsupported]) .tab-label-container {
     height: initial !important;
   }

This counteracts a change in 96.0.2 which sets the height of that element to 2em.

I have a set of tabs (web pages) that I use when I open Firefox. Over the past 4 - 6 weeks the tabs all go away after I shut down Firefox. When I reopen it has a single tab. It is frustrating since I am working on a project and have to reopen 8 tabs.

It worked for many years and now it has stopped.

Hello, I've had this problem before I believe and I had to change something in about:config to rectify this issue but cannot find it nor know exactly how to search for it.

I have two Microsoft Online accounts, Account A and Account B.

When I go to a website I am prompted to pick an account and I can see Account A and Account B. I then enter my credentials for Account A and I'm in, great.

I then go to another site where I need to use Account B, but I don't have the chance to pick Account A or Account B because I'm presented an error because the new tab is trying to use Account A.

How do I stop this?

hi, it has been 2 days since firefox starts to behave in an unusual way. when opening many tabs, and if i dont click on them (ie inactive) in 2-3 minutes, they go blank. when i click on an inactive tab, firefox quickly refreshes it and shows the page. example: let's say i have 3 open tabs: tab1, tab2, tab3. i am reading in tab3 for 15mins. in that period, i didnt click on tab2/1. if now i click on tab2, it is blank and no longer displays the content of the page it is supposed to show. then, firefox quickly refreshes the page and displays the true page.

not really sure why this is happening now. never happened before. it is a really annoying behavior as every tab had to be refreshed automatically if i dont click on it in very few minutes. firefox 96.0 ubuntu 18.04. thanks

I've looked through every question on the Support site regarding saving pinned tabs, but can't find a specific answer. I have a pinned tab, and in my Settings under Startup, I have the "Open previous windows and tabs" box checked. However, every time I re-open Firefox after previously closing it, the pinned tab is gone. Is this because I close Firefox using the "X" in the upper-right-hand corner or simply close all the open tabs?

I have consulted https://support.mozilla.org/en-US/kb/how-do-i-restore-my-tabs-last-time. That article says:

-Click on the menu button [three lines at the upper right] to open the menu panel. -Click History. -Click Recently Closed Tabs.

I am using Firefox 95.0.2 for Mac (iOS 10.15.7). There is no "Recently Closed Tabs" option to click after clicking on History per the above instruction. I have saved various files from the time of the crash, in particular "previous.jsonlz4" (a 20.6 MB file, as I had a very large number of tabs open). Is there any way to use this or some other file to restore my old tabs?

Dear Mozilla/Firefox,

I've been using Firefox over the last couple of months/years but I just can't get the restore recently closed tab shortcut (CTRL+SHIFT+T) to work on my windows PC.

Here's a (Loom) recording of me showing that Firefox does correctly track the history of closed tabs and that I can click on them to restore but the shortcut (which is also mentioned as CTRL+SHIFT+T) just won't work: https://www.loom.com/share/7048894683654dccb4926aa4dd09e6a6

What I've tried so far: - Check if the history is actively collected - No I'm not using private browsing - I've read another support thread to check "about:config" and in there check that "browser.sessionstore.max_tabs_undo" is set (in my case it's the default 25) - Disabling all extensions (which I don't think are any suspicious or weird ones but disabled just to check - see attached image) - Resetting Firefox through the windows uninstaller - Fully uninstalling (using Revo Uninstaller with advanced check) and reinstalling Firefox

Please help me because I'm about to quit Firefox for such often used feature just not working...

P.S. it's working perfectly on my Macbook and I'm running the latest 96.0.1 64bit version

Updated web browsing. Generally, tabs don't have a clearly defined visible outline. Bookmarks, too much space between rows, so e.g. less bookmarks are visible - have to scroll down to find. Make firefox easier to use, not harder. Need to have defined contrast on the page for each process or thing that you're doing e.g. buttons, lines, whatrever should have a clear contrast so you can see quickly. Time should be spent doing what it is you're doing, not spent trying to see firefox properly etc.

Before updating to Firefox 96, I could close tabs no matter how squished they were. Now I cannot. Someone with a similar problem at https://support.mozilla.org/en-US/questions/1194322 was able to find help, but I'm not meeting with any success implementing their chosen fix. Is there a way to keep the close tab button active with this many tabs anymore, or is that out?
