After update to 141.0.3(64bit), sidebar comes with waste space, as pink area in attached image.

It didn't shows in these years I'm using FF, I want to remove it but keep sidebar exist, like it was before. Where can I adjust it ?

If it's needed to be exist, why not put it on top of Sidebar ?

I signed onto my parents computer that was assigned to a school district and now everytime I open firefox on any of my devices their website keeps popping up. I've signed out of their computer and have tried deleting and reopening my account, and nothing seems to work.

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

When I select Dark Theme, I DON'T wanr to see this. I just noticed this on my Linux Mint desktop machine tonight when I logged in. I also have Dark Reader installed and it isn't affecting ioit eitherit either. Make this go away. It burnsssssss!

The issue is very simple. When loading into the roblox website, the page becomes almost completely empty aside from the buttons at the top like Charts, Marketplace and the roblox icon at the top left. All of which do nothing when pressed.

The weird thing is that it works completely fine on an incognito tab..? Now I noticed something similar happening with other roblox's websites, where some parts of the site would break in very similar ways, but I thought nothing of it cause it didn't affect me too much. But after the new update, it extends to everything, not just one sub-page of roblox, the entire website is like this.

I removed my extensions and restarted my browser to see if that would fix anything but it didn't help.

In the webpage

when I click to listen to play a segment (▷ Listen) it shows momentarily a button but then returns to the original (▷ Listen). However, when I open the page in Chrome it plays without any problem. What could be the problem?
