Firefox Community Forum

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.

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 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.

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 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.

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!

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.

The pdf gets overwritten by the new text when it is scrolled down or up and the whole pdf becomes messy. I have attached an image showing the same. The terminal gets into the background of the pdf and any other application that is opened on the screen.

Hi, so I've "Show an image preview when you hover on a tab" setting under Tabs section "Off". Preview is not showing but instead there is am empty box like on attached image. I couldn't find any other option to turn that off also.

I'm using latest firefox nightly release.

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?

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!

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).

I'm trying to replicate my windows setup in Fedora 42. I have been really liking the new vertical sidebar tabs option in windows. I have a lot of tabs and so rely on inertial scrolling to flick through them quickly.

However, there's odd behaviour with this in linux. With the window protocol set to xwayland, inertial scrolling on the sidebar tabs works, but inertial scrolling does not work in websites. Setting the window protocol to wayland (the general online recommendation to fix inertial scrolling), inertial scrolling in the tab list does not work, making them much less useful.

Up until now, if I search using the Wikipedia field on the menu bar, it opened in a new tab, just like using Startpage does. I've just upgraded to Fedora 43 and Firefox 146.0 (64 bit) and it's stopped doing that, although Startpage still does. How can I get that functionality back?

I frequently have the problem of accidentally detaching tabs when I am trying to drag them left and right to reorder them. The interface seems more sensitive than I would like. The unwanted detaching of tabs happens to me many times a day and is jarring and causes me to lose a lot of time trying to put the tabs back. I would like the interface to be less sensitive, i.e. to make me drag it much farther up or down in order to detach the tab. If the feature to fine-tune the sensitivity of the tab-break-off is not implemented, I want the ability to turn it off, so that I can reorder tabs by dragging them left and right without having to worry about them detaching.

I searched and found an 8-year-old request from another user for the same thing, and it had been closed, and linking the user to third-party extensions adding this functionality. However, the extensions were not monitored by Mozilla for security.

This was a non-solution to me. I want this solution either to be built-into the browser, or to be offered in an extension that is monitored for security by the official team.

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.
