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 have Firefox Focus set as default browser on my Android phone. When it is used as Custom Tab, it cannot handle opening URL that is supposed to be opened in a new tab and did nothing instead.

My use case is, opening a link from Telegram message, the webpage is opened and is rendered in Custom Tab. Click on a link that is supposed to be open in new tab. Expectation is the new page will be opened, but it's currently doing nothing.

Is there anyone experiencing the same?

Today after i restarted my laptop (windows) and then I started firefox all the pinned and also the normal tabs were gone. I tried to follow different indications about restoring the previous session, but nothing showed up. All the tabs are gone.

As I need these tabs and this is obviously an issue of the software, PLEASE FIX THIS ASAP.

Is not possible that this happens every 1-2 months.

When i downloaded the app, it automatically came with the ability to group tabs, but after i customized several settings it took all of my tabs out of the groups and i can't group them anymore. The settings i changed ranged from privacy to personalization, i tried to reverse some of them to see if that would help and did a bunch of back and forth, but it's still not coming back. (Im trying to leave chrome because i noticed it had some very concerning lack of privacy settings that messed with my phone's ability to function properly if i turned them off. And Edge is worse.) Firefox seems better, but without the group tabs option it makes it waaaay too ridiculous to try and do any real work with it. I do a lot of multitasking and research and need to be able to bounce around and organize stuff. Your help stuff on tab groups doesnt say anything about how to turn it on or off. So... how do i get it back?

In previous versions of firefox for ipad, a blue notification was shown temporarily at the bottom of the screen when a tab was closed, allowing to tab This was really helpful, as it happens quite frequently, that I hit the close icon accidentally when switching tabs. Any chance this feature can be enabled again? Thanks

I use Firefox in Windows 11, but when I close it and reopen it, my three open tabs are gone, it is supposed to open them, as checked in settings. I see the same thing happening in the MacOs, but no answers for Windows either.

MacOS 26.6, Latest Firefox. 153.0.3. Tabs are not restoring, since update to latest FF. Tab History shows old stale tabs, not the tabs that were present at time of exiting Firefox. I had closed those tabs. Is this an artifact of caching?

The active tabs should be stored at FF shutdown, not the old closed tabs prior to that. This Firefox quirk is both on my Mac Mini M4, and on my MacBook Pro M3. Kind of a pain in the neck to restore where I was. It's enough to make me reconsider this browser - which I have used for decades, using Windows, Linux and now MacOS.

I researched how to restore a session. It told me to go to History and click Restore Session. There is no line with that name, in my Firefox, on a Mac.

Under History the docs show 4 items before "Clear recent history...", I only have 1. Recently closed tabs 2. Recently closed windows 3. Search history. There is no Restore session.

The tabs that were open last session are in the start up window, and the check box is set to restore tabs and windows. But my tabs were not restored. (I only had a single window open.)

What can be done to "restore" previous behavior of Restore Tabs and Windows? Thanks for any and all assistance.

Hi all, I recently updated to the most recent version of Firefox on Android but am not seeing any options related to or about using tab groups? My friend who is on the same version, OS, and different model of the same device has the option to create them and a tab for them neither of which I have. His about page matches mine

I've attached a screenshot of the about page below, and my device is a Galaxy S24 FE

Thank you in advance

It seems I can no longer set a link to open in same tab. There is a Government webskite that won't let me open a link in a new tab and I can no longer find a way to stop a link being opened in a new tab
