Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

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?

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.

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?

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

When I open many new tabs, I'd like them all to be loaded immediately (as soon as they the new tab is created, a.k.a. eager loading). The reason is that, when I click to actually see those pages, if they are already fully loaded, that will make user experience much smoother.

Please see attached image for a demo of current behavior: browser had plenty of time to load those new tabs in background, but it didn't.

I understand that lazy page loading is a way to preserve RAM and CPU cycles. I know that is usually a good thing for users who are used to working with only one thing at a time and/or have limited hardware resources. However, I think there should be an opt-in feature of eager loading, which would optimize a lot the time for experienced/heavy users.

Thank you!

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

I am using firefox on ubuntu (firefox 142.0.1 (64-bit)) and using vertical tabs in the side bar. I recently started using the new(ish) feature of tab groups and I absolutely love it. I was using STG (simple tab groups) before and that fine, but this is way nicer. The only small annoyance I have, which could be a mistake on my side. Is that some of my tab groups are shortend seemingly randomly? If I for example make a group named "phone" it is visible like that, but after a couple of hours it goes to "ph...". I thought it may be sidebar width not being wide enough, but you can see in my screenshot that is not the case. Strangely if I make a new group it is always complete.

So I was wondering if I am missing a setting or config entry.

Thank you for reading and hope you have a great day!

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

The AI tab thing is a problem for me for multiple reasons. I found various articles about how to turn it off. They pointed to the following setting: In about:config set the setting "browser.tabs.groups.smart.enabled" to false, and then restart Firefox.

However, when I do that, and then immediately go back to about:Config to check the setting, it has changed itself back to "true".

Other settings accept and keep permanent changes. This means that I'm not forgetting to save the change or anything. Just this one setting (which turns off something causing me problems) refuses to actually stay set.

I see the answer to this question https://support.mozilla.org/en-US/questions/1509077 and tried looking there. There is a completed study called "Smart Tab Groups Rollout", but since it is in the "Completed Studies" group, I cannot remove it.

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 :)

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 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

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

Hi all,

Sometimes Firefox just closes a couple dozens tabs - I keep around 200 or 300 open - without my request or confirmation. It's not frequent, but quite annoying. Clicking History > Recently closed tabs > Reopen all tabs does not restore all. I don't know where I can find references for the lost tabs or Firefox logs where I could check what happened. My only suspicion is that I inadvertently rest my hand or finger somewhere in my notebook's trackpad, and somehow Firefox understand that as a request to close several tabs at once, but I have no clue if that makes any sense. I didn't test in Safe Mode because this happens too unfrequently for me to tell if Safe Mode avoids the problem.

Could you pls help me finding the reason for that? Does Firefox keep any kind of log I can check? Are there any keboard shortcuts or mouse/trackpad action that can be set up to do this?

Firefox version: 153.0.1 Distro: Linux Mint Version: 21.3 (Virginia) (Based on Ubuntu 22.04 - Jammy) Kernel: 5.15.0-186-generic

Thanks!

I would like to make Firefox web browser to save automatically the "tab group" created.

The feature is already there by left clicking on the group and choose "save and close group". I would this to be automated as default behaviour at every attempt to close the last tab of the group, so the "tab group" never gets deleted by itself. Only deliberately left click on the tab group and choose "Delete group".

Thank you in advance for your time reading this. 🙇
