I have the same problem as described here [1]: when I open a markdown file in Firefox it uses itself as handler opening it in a new tab, which in turn opens it in a new tab, ... The solution suggested under [1] is how to make Firefox usable again, stopping it from open this particular markdown file. But it doesn't solve the actual problem: either Firefox is capable of rendering markdown in which case it should do it; or it's not in which case it shouldn't try. Does anyone have a thought on that?

I've recently started using the Tree Style Tab extension, and I'm finding it useful, but I'd like it if the list of tabs could be automatically hidden when only one tab is open (and automatically shown when more than one tab is open).

I hoped to write an extension to do this, but opening the sidebar from an extension requires a user gesture, so I suspect I'll have to use a userchrome.js script.

From a "userchrome.js"-like environment (i.e. unsandboxed AutoConfig), I can hide and show the sidebar with `SidebarUI.hide()` and `SidebarUI.show("treestyletab_piro_sakura_ne_jp-sidebar-action")`, and I can examine the tabs open in the current window via `gBrowser.tabs`, but I can't see how to get notified when the number of tabs changes (replacing `gBrowser.tabs` with a proxy doesn't work, for example). I suppose I could just check every few seconds? That feels like a bit of a cop-out, though, and gets more and more inefficient the more windows are open.

There's an API for extensions to receive events when tabs open and close, so clearly this is possible. Where should I be looking for this functionality?

(I also don't know how I would go about unregistering an event listener (or cancelling a setInterval call!) when the window closes, assuming that's necessary to avoid leaking resources – is there an event like `chrome-document-global-created` I could listen for, but that fires during teardown of the window rather than when one is created?)

I using kubuntu (ubuntu with kde) 22.04 and firefox will not recognize my security key. There is a really good thread on this here. It is now closed.

https://support.mozilla.org/en-US/questions/1412073

One of the solutions is to install firefox from the mozilla server. On other forums, this is referred to removing snap and installing the debs. I haven't tried this.

Reading through the thread however, it seems like the snap version should work. The manufacurers id and product code for my Thetis FIDO2 usb key are present in the etc/udev/rules.d/70-snap.firefox.rules

This answer says to disable apparmor. I tried that, but it didn't work.

I have quoted this answer below.

This isn't actually a firefox problem. KDE Neon uses the firefox package from the Mozilla Team PPA and there's nothing wrong with that package. The problem is that Neon enables app armor on firefox which breaks access to password managers and security keys. sudo aa-disable usr.bin.firefox works around the problem by disabling app armor for firefox. aa-complain was not sufficient in this case.

Is there anything else I can try?

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

I view a lot of PDFs for electronics design. And after some time with the browser running it starts to garble PDFs. I have not found a trigger. Sometimes it opens fine in a new container tab or private browsing, other times nothing will open it. Very occasionally refreshing a few times makes it load correctly. The error doesn't manifest for all PDFs at the same time. Open ones will remain viewable, and once the error occurs some new PDFs still open while others fail consistently. Sometimes opening the same PDF as a file from my local drive makes it render.

The rendering error is a bit unlike anything I've ever seen. There is a lot of X and Y spearing like it tried to render the same text and images in slightly different spots over and over again. When I switch virtual workspaces and come back some parts of the rendered page retain the contents of the previous workspace and others do not. Scrolling produces jitter and additional smearing.

One somewhat reliable way to trigger the error is to put the laptop to sleep and wake it up. That always causes PDFs to exibit this error but often refreshing the PDF will work to restore it. Not reliably though.

I've attached an image of the error captured with my phone because neither screenshots nor OBS can actually "see" the garbage on screen. Apologies that this error is so full of inconsistent behavior. I've lived with this for some time now in the hopes that it was a temporary problem and tried to work out what causes it but I can't find anything other than putting the laptop to sleep being a cause, and even then it is not the sole cause.

Firefox Getting Unusuable

Hi, this is going to be a long one, so many things... Using Firefox the latest Ubuntu LTS, with the latest Firefox from Snap. I'm a very long term Firefox user, never had any real troubles unit recently. I have a vast number of cookies, saved passwords and so on. Reinstalling or deleting cookies or such isn't an option unless fixes are guaranteed to work - if I have to start over then I'll do it with Opera, that is where my grumpiness indicator is at.

The set up is two monitors (working as a single 'screen') attached to an Aspire PC (Aspire X seems to be the model?). I tend to have 'stuff' going on in the left hand monitor, YouTube on the right. The PC is on all day. I know there are log files, but I don't know which is for what or where they are. I use AdBlocker Ultimate.

So what's happening is: Firefox crashes quite often at any time - 'Firefox is not responding - force quit or wait' - always have to quit. There doesn't seem to be any repeatable way to cause this, it seems random.

When the mouse enters the YouTube window (the drawing area, not the actual window) it disappears until the pointer moves out of the window. Jiggling the window size sometimes brings it back, but...

When the mouse pointer actually appears the window is completely unresponsive - clicks don't work, nothing highlights and so on. After somewhere between 10 and 30 seconds things will work for 2 or 3 mouse actions (clicks, drags etc) then do it again. Unless I give it plenty of time, clicking on a video will play a pretty random one - Firefox seems to lose track of where the pointer is.

If I comment on a video the I get about 5 to 10 characters in then nothing happens for 10 to 20 seconds, then any queued characters are shown. Rinse and repeat until the comment is complete - it takes ages.

YouTube is the biggest problem, but there are some glitches in other Firefox windows, I'm supposing that the problems are audio/video related.

None of the above happens with Opera. It's getting to the stage where Firefox is unusable.

I've googled and searched this site but the there seems no solution.

Any help appreciated.

When pausing/starting or moving video feedback volume changes to an fixed volume. Opening video player in youtube default volume is at 41%, I put in at 100% but when I pause it or change to another part of the video, the volume changes to the default again. It's not from OS because with chromium browsers doesn't happen (brave,steam chromium) and with librewolf happens. Wanted to publish a 10 sec video showing the error, because I don't know how to show it with photos.

Hi,

I'm experiencing a problem on Firefox 125 and 126 on Red Hat Linux 8 & 9 and also on Ubuntu 20 and 22 systems.

We have a proxy pac which we have tried loading from an http url, or a local file and both produce the same result.

  • Launch Firefox, no access to Internet sites (i.e. no proxy)
  • Enter settings and Reload proxy pac
  • Proxy works perfectly

Is there any way to force the proxy pac to load on Launch? Why isn't this the default behaviour? or am I doing something wrong?

Thanks

Hi all!

A while back I downgraded my Firefox version to some old version to be able to access a FortiGate 310B. However when I upgraded back and started using the latest version my search completion stopped working, but my search completion is turned on. It shows things I've already searched for, but it's not fetching new completions. I lived with this for a while since I couldn't be bothered to fix it, but I recently moved to linux, and copied all my data, I did this by just copying the profile folder and moved into into a new profile I created on linux. It worked, my bookmark, history, passwords etc are saved, but still no completion. I tried creating a new profile and the search completion worked perfectly fine. Do you guys have any tips or things I could try? Or do I just give up and move to a new profile, since this one is presumably corrupt?

Any help is appreciated, cheers :)

I frequently stumble upon websites with incredibly annoying looping images, with no option or method to disable the image changes. Reading information on websites with constantly changing images is difficult due the distraction.

It would be greatly appreciated if an option could be created to disable the continual image looping - perhaps an addition to the FF settings whereby an On/Off toggle could en/disable a context menu option to Pause / Disable image looping when the user right-clicks on an image. ... or, the browser itself automatically recognises image looping and the toggle simply allows FF to en/disable the looping.

Thanks.
