Hi, I want to make a simple extension for Firefox that auto toggles vertical tab based on the aspect ratio of the Firefox window. I found `sidebar.verticalTabs` in about:config that toggles vertical tabs, but a simple googling tells me that it is not possible for web extension to modify about:config values. Is there any other API that toggle vertical tabs? Thanks!

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.

Firefox doesn't launch with previously used windows and tabs if you closed the window while having a private window open

Version 140.0.4 (64-bit)

As the title states, if you have a private window open and you close your main (non-private) window and attempt to relaunch Firefox (mine is at the taskbar) you will then encounter a window with none of the previously opened tabs and simply a single fresh tab. This is despite having the setting to continue browsing where I left off in the settings ("Open previous windows and tabs") enabled. Luckily the lost window can be recovered by going to History -> Recently closed windows -> "___tab names____"

Hi Team, I am using Linux Mint 20 Cinnamon. Cinnamon version is 4.6.6. The issue is that I was browsing and by mistake I selected one tab then dragged it for sometime and then released the tab but that created a new window and now the old windows are not visible in ALT + Tab function. The windows are showing in the Firefox task manager and also the box icon in the top right corner in that "open tabs". Now I am not able to even change the window or able to access the opened tabs. Attached the screenshot and as you can see in that there are total 4 windows showing in firefox and one as active but in the bottom on the firefox icon you can see its only 1 window. How can I access the remaining 3 windows? Found one ticket (https://support.mozilla.org/en-US/questions/1477845) in this the recommend solution does not work. When I try to click on the window 1 tabs then I do not get any response. I tried both the solution but none worked.

Thanks for the help in advance. @Mozilla team member is seeing please check and fix this bug if possible.

[I use firefox on Mac, Windows, and Android, but the issue seems to effect me mostly on Mac and Windows) I'm just guessing this to be a browse issue. However I won't miond the post being moved to a more relevant sub-forum.

I keep arriving at this solution when searching for a solution to the increasing number of sites using the irritatingly abused stay/leave page question-dialogue box which pops up when i want to leave a page. The common solution appears to be https://userscripts.org/scripts/show/23865 However, when this page loads, I just get an empty box which looks like one of those ones which normally contain scripts to run or stop running certain things, or even to add or embed items etc.

When researching I often need to load lots of pages top go through. however, when i then need to close them all, i end up manually having to complete these irritating dialogies which are OBVIOUSLY really meant for pages where you may be filling in a form, or editing something, and perhaps have not completed filling it in. However, many sites irritatingly abuse this and just add the feature anyway. It just tells yiou they are dodgy rather than trustworthy. Any up-to-date advice as on July 2025? Any trusted new extensions/addons for this as with auto-cookie form-fillers perhaps?

Support Firefox to be able to use different tab view modes on different windows! For example, two Firefox windows on different monitors, in my situation below:

- One on a 1920*1080 hori screen, with vertical tab sidebar disabled - One on a 1080*1920 vert screen, with vertical tab sidebar enabled for this window only in this case.

It brings much more convenience, at least for situations just like mine :)

hallo zusammen wo finde ich in firefox eine funktion, die mir die zuletzt angesehen und geöffneten tabs wieder herstellt?😐

in den einstellungen ist "Vorherige Fenster und tabs öffnen" angehakt.

es kommt aber wiederholt nach updates dazu, dass die letzten fenster und tabs nicht wieder geöffnet werden, sondern nur 1 tab mit der festgelegten startseite.🤷‍♂

muss ich mich damit abfinden, dass die letzten tabs hin und wieder im nirwana verschwinden? oder gibt es auch dafür einen tipp für laien?🙏

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)

Sidebar for vertical tabs vs horizontal tab behaviour (Fullscreen use)

Hi,

I started using the 'Vertical tabs' option to manage my tabs. I prefer it over the horizontal bar. However, I noticed that when going fullscreen (F11) the vertical tabs are not removed. This is different from horizontal tabs, which are removed from the UI when you press F11.

I think that's because vertical tabs are tied to the sidebar altogether. Is there an alternative to have the vertical tabs work the same as horizontal tabs?

Horizontal bar behaviour in fullscreen:

- The horizontal bar disappears when going fullscreen (F11) - The horizontal bar reappears when hovering the mouse over the top of the screen (which is great!)

Vertical bar behaviour in fullscreen:

- The vertical bar does not disappear and gets in the way of the fullscreen (F11) experience - Checking the setting "Expand sidebar on hover" does not replicate the behaviour of the horizontal bar reappearing upon hovering the mouse. Instead, the smaller version of the sidebar remains and it expands to it's full size when the mouse hovers over it - The only option is to remove the sidebar altogether, which means going back to horizontal tabs
