Firefox Community Forum

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

I love vertical the tab view. Unfortunately, on one of my systems, vertical tabs to not render correctly. Groups are shown, but there are no favicons or titles shown (see attached image). The tabs are also not clickable. Any insight into how I could debug that would be amazing!

Every time I open Firefox, the checkbox next to "Opening links in tabs" always disappears, even though I've checked it in previous sessions. How can I make it permanent?

I use Firefox on the Linux Mint operating system.

I have lots (~100) of tabs open, distributed among windows and virtual desktops. Every now and then the laptop fan starts running wildly, and I identify a CPU hogging webpage in about:processes. How can I now switch to the open window/tab of that webpage to close or unload it? I would expect a click (or context menu item) within about:processes to bring me there. Currently I have to scan through all desktops/windows/tabs to find the page.

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

Hello! I really liked the vertical tab panel management before, if I wanted it to disappear I've pressed ctrl + alt + z and if I wanted it to show only icons of the websites - I could press ctrl + alt + x twice and had the mini version of it. For some reason, now it's gone, when I press ctrl + alt + x twice the panel is gone completely. Could you help out here? Essentially, I want to be able to make it look like that (screenshot attached), only without the AI Assistant.

I have MozillaFirefox-140.4.0-150200.152.207.1 on OpenSuse Leap 15.6. In my "Settings" under General and Startup I have always had the option "Open previous windows and tabs" checked.

This just started happening recently. After the first time it happened, I restored everything by searching through "History" and recreating the tabs and windows. Everything seemed OK for a few days then it happened again.

So, I've just went on a quest to find a solution to my pinned tabs disappearing every few days, and it seems like this can happen if I don't shut down Firefox properly. Is there a way to stop this from happening?

That's my question. The rest of this is curiosity about the issue since it's seemed to have persist for a few years:

Is this intended behavior? No other browser I use does this and judging from the hits I got here, and elsewhere, it seems undesired. Is there some security or privacy reason it's like this?

I know I can repin the tab, or take some session recovery steps, and a few other things... but IMO, those are workarounds, not solutions. Barring some technical or mission limitation, a true solution should prevent this from happening at all.

How to sort Tab Groups alphabetically in the Add Tab to Group Menu?

I want to add tabs to groups bit the groups are changing their position and it would be very helpful to (optionally) have the freedom to sort Tab Groups to appear alphabetically in that menu!

But that should NOT affect the sorting order in the browser window!

But of course it also would be helpful to have the freedom to also sort the tab groups order in the main windows, but please make it a different sort order than in the Add to Tab Group menu dropdown.

Thanks!

That tab grouping "feature" really is too much like modern software developers' tendency to roll out a new "feature" and turn it on automatically no matter how annoying some users may find it. Some times when a mouse cursor goes too far and wanders into that tab zone, Firefox starts grouping tabs. Please allow us to turn the thing off.

If I open a tab to a specific google sheet I use it won't let me use the split view option (it's greyed out)

I would like to be able to split view the sheet so I can keep an eye on the running totals while I am entering data elsewhere on the sheet.

Split View is enabled and works on other tabs

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.

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

This happens on Firefox for Linux Mint 149.0 (64-bit) brand new profile.

This occurs when there are multiple tabs open to the point that they need to be resized after closing a tab.

When I attempt to close another tab with a middle click, all the tabs are resized on the mouse click down action. The tab that is newly under the cursor when middle click is released is closed. This is causing unintended tabs to be closed.

Any help or workaround would be appreciated.

Thanks, Tim

Is there a way to disable tab groups without going through about:config? Because I can't find it and there really should be...I have no idea how that feature works, I don't want it, but I keep ending up with groups unintentionally. I still don't know how I'm doing it. It's incredibly annoying and apparently incredibly easy to accidentally trigger and I'm sick of losing tab space to these random colored boxes for no apparent reason!
