I am using Ubuntu 22.04. Firefox version is 143.0. IIRC firefox recently updated. I have the setting "Open previous windows and tabs" checked. Until very recently it has always worked but now when Firefox is closed all tabs are lost and don't appear when reopening Firefox. How to fix???

Latest update on Ubuntu force reset the sidebar. Reminder for those that do not want, the process to remove it is:

  • Go into about:config in the address bar,
  • search for sidebar.revamp,
  • set it to false.

From this Reddit thread.

Mozilla. Please do not reset the `sidebar.revamp` for those of us that have gone to the trouble of removing it. Thanks.

I have picked up some bug(s) on my Firefox that I cannot figure out how to get rid of. With a Firefox ID I have warnings of 3 Trojan Virus detected, Virus detected, hard drive infected, secure data notice and system alert. I also got a warning that my McAfee protection had expired which is very strange. Since switching over in 2010 from Windows to Linux I have never had protection of any kind and unlike Windows have never had a single problem. In addition when I was using Windows the protection that I had was never McAfee. I suspect that these warnings are not from Firefox given the misprints, spelling errors and the poor English. It is likely phishing from some third world country. How do I get rid of this obvious garbage permanently? Many thanks! Kris

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

Hi,

I discovered today that the installation of Firefox I have has modified some emoji, like the flag of Switzerland has been replaced with the one from Sark. See the screenshot looking at the same website with Firefox on the left, and Brave on the right:

There's a big mess in the flags' emojis apparently looking at a page showing all the countries. See second screenshot.

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.
Super User
Ask Ubuntu
A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”
Reddit

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.
Reddit+1

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit

Thoughts? Solutions?

Thanks in advance.

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

Ubuntu 22.04.5 (kernel 5.15.0-153) Firefox updated from 142 to 143 automatically by snap.

In version 142 and older, html file with image source pointing to local (remote) network image file displays properly.

In version 143, this does not work anymore. I tried changing the image to point to a local computer file and it works.

In verion 143, If the link to the image is typed directly to the address tab in firefox, it works.

Perhaps some config setting need to be changed? Hope somebody can help.

Thanks in advance.

firefox network tab shows NS_ERROR_CONNECTION_REFUSED

I have downoloaed Firefox offline installer (a .xz file) from here:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/139.0b9/linux-x86_64/en-GB/

I have also downloaded a .asc file, presumably a pgp signature.

Now both files are saved locally in my computer.

Assuming Linux latest release, how do I verify the contents of the offline installer file (.xz) from the Linux Terminal? I have install gpg tools. And commands like ```gpg``` are available.

What I did so far:

 gpg --show-keys --with-fingerprint firefox-139.0b9.tar.xz.asc

with this output:

 gpg: no valid OpenPGP data found.

Do you really want us to verify the contents of the installers you provide? A sha256 sum would be great, though not as secure, for when the GPG predictably fails for the ordinary user due to its huge and useless complexity and bureaucracy.

I'm running ubuntu linux... which results in accidentally clicking back midway through a video or podcast and losing my position more often than you'd expect... any idea how I might either reassign or disable them entirely on the software side of things? thanks. -dan

I was previously successfully using the translate selection with the translate dialog automatically detecting the language of the selected text. Then, with that dialog open, I tried changing the from/to language - you know, just messing around - and now it refuses to automatically detect the language. It is now stuck on Tranlate to French. I've checked my settings page and my default language is English. Where is it getting the idea I'm French? Annoying af.

How can I get the automatic language selection to English as it previously was?

NOTE: As I was composing this request, I visited the Amazon store - as that's where I use the feature most - and noticed it's probably the tool itself that's broken recently as it was getting it right all the time before but now it's hit or miss. Again, annoying af especially because I've come to rely on this a lot. Please fix.
