In fully updated Windows 10 (x64), running either 64-bit or 32-bit Firefox, the tab bar in the current Release channel of Firefox disappears. No changes have been made to the Firefox profile on my computer, including no edits in CSS, etc. (I never bother with such things). Updating to 108 and higher causes the tab bar to disappear. In 108+, a single tab appears "somewhere" at the bottom of the window (its location appears to be random), and the New Tab button ("+") is gone as well. Disabling all extensions has no effect. Reverting back to 107.0.1 (either 32-bit or 64-bit) fixes the problem. This situation has been tested several times with the same result every time. Consequently, I have edited the Firefox registry policy to disable updating so I can run 107.0.1 without constantly getting the Firefox "nag window." Any thoughts on this problem would be greatly appreciated.

Hello,

When Firefox updates, a new tab is openned upon the next start, with the new version content or patchnote. I would like to avoid this informative tab.

Is there a way to deactivate it?

Thank you in advance.

So, a preface. I rarely used this PC of mine, and thus the Firefox is rarely used as well. When i installed it, i turned on the option 'Open previous windows and tabs'.

Then, once I opened up some kind of offline documentations from Libre Office or Latex, which opened in Firefox. You know, the one where there is no tab appeared, and it just seems like a single pop-up window. I closed it without thinking.

Long enough, i forgot about that and opened up Firefox only to be met with that docs again. Okay, i closed it. But Firefox always started in this kind of pop-up window style ever since (attached). Changing the preference, even deleting the profile doesn't seem to do a thing.

Any recommendation to return Firefox to its original set?

Help? I rebooted my machine and lost all my open tabs. any attempt to re-acquire them shows just the ones I have open now. It doesn't show any of the ones that were lost. Thanks Monica

Firefox 110.0 64 bit on Linux Fedora 37. Happens with my default setup and also when running with extensions disabled. Default font. English Language.

If I got to this website https://www.endesaclientes.pt/uPortal2/MyEndesa/index.html#/login, right now, it is in maintenance mode. It's tab label shows up as "Em manutenção..." when it should display "Em manutenção". In case this text field munges my text, see image of the tab, and the letters between "uten" and the final "o" are supposed to be a c with a cedilla and an a with a tilde.

Do I need to change my configuration to add the proper font in tabs?

I recently upgraded to Windows 11 and installed the newest Firefox 111.0. I'm familiar with about:config and all general settings in programs involved.

I used to have any link open in a new tab, but stay focused on the current one. DuckDuckGo search results opened new tabs but stayed on the search results page. I can no longer do that and can't figure out what changed or how to return it to this behavior.

In short, "Open previous windows and tabs" is no longer working. I'm using version 111.0 (64-bit).

I have done the following: 1. Troubleshooting mode 2. Removed or disabled all my extensions 3. Refresh Firefox - twice! 4. Disconnect sync across my two laptops

Still, nothing is fixing the issue. My previous windows and tabs are not being restored.

Help, please!

Since one of the last updates the behaviour for the tab re-sizing got messed up.

When there are only a few tabs with full size, those as well as the additional plus icon is shown. But when there are more tabs and they are re-sized, then the right side gets cut off. First the new tab icon dissapears and then also the last tab get's cut off.

I attached a screenshot with three firefox browser windows showing the problem, as well as a forth one with only 3 tabs open, which are shown in full size including the new tab icon.

This is a new problem as the tab resizinng and the new tab icon used to work perfectly fine no matter how many tabs were opened.

Same as this question, but the answer is outdated: https://support.mozilla.org/en-US/questions/839240

Is there a way to do this in the about:config page?

There is an answer about holding `Alt`, but that is a workaround.

i used jeffersonscher to get all my tabs back from by old session but i restarted my pc and the session store jsonlz4 file got changed with a new one that didn't have all the tabs i previously had on it. When i did the restoring my jsonlz4 file was at 1:08am but when i accidentally restarted my pc it now is saying 2:31am and all the tabs that i have restored so far are on it but not the ones i haven't restored are not.

So is there a way to be able to get that old jsonlz4 file back so that i can restore all the tabs that i used to have.

Please help.

How do I enable container tabs? The option to open a new link in a container tab has disappeared and the prompt doesn't show up when I long press the new tab button either

Hi, I disabled several options in About:Config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and moved to it automatically. Whatever you do with the current tag, I want it. Please help me. ( I mean, it no longer applies to bookmarks, I want it to apply to bookmarks )

Had the line

.tab-close-button:not([pinned="true"]) { display: -moz-box !important; }

in my userchrome.css which put the close button on all tabs. This no longer works.

Also there is no Close Button (X) on hover for inactive tabs.

Currently I'm using the css from this thread https://support.mozilla.org/en-US/questions/1341968 Now with firefox 113, this no longer works, I'm hoping someone can help me with this.

Till version 112 I used this in my userChrome.css to get back the close buttons on tabs, but only when I hover over them (active or inactive tabs): .tab-close-button{ display: none } .tabbrowser-tab:not([pinned]):hover .tab-close-button{

   display: -moz-box !important

}

But now with version 113.0.1 it doesn't work at all and no X appears when I hover over my tabs.

I tried adding #tabbrowser-tabs[closebuttons="activetab"] on top of the previous code, but it made the X appear all the time.

How could I update this code so I get the desired result only when I hover over a tab?

Firefox opens with a new tab containing 8 links per row. However, all subsequent new tabs have only 6 links per row. They used to always have 8 links per row. Why? A bug or a configuration change? I have made no changes.
