I use Firefox on Ubuntu 21.04 LTS and recently started facing delay of 3-4 seconds while trying to open any add-ons in top bar or even when trying to navigate application menu. I recently moved from windows to Ubuntu, no such lag or delay was there in windows.

What I tried- I tried to troubleshoot this problem with the help of troubleshooter present in Firefox and used the 'Refresh Firefox' option but still it was lagging too much. I also tried to remove all add-ons but still it was of no use. My system is fast enough to handle Firefox.

Hi!

Been test driving Proton and quite liking it, but on both FF 89 and 90 im running into issue where opening bookmarks or history via library menu freezes browser ui. Restoring and maximizing window restores the functionality again until next time i try to access said menus. After restoring and maximizing it seems like all the actions i've tried happen at once. See video https://imgur.com/a/8f2tl0l. I have roughly 100 bookmarks, so that shouldn't be an issue.

This happens also on completely fresh install without any backups and new profile. As soon as I import my bookmarks or even bookmark couple new, random sites without restoring old bookmarks, this problem begins manifesting itself.

I've tried troubleshooting mode and that helps, but im still sure what causes the issue as just disabling hardware acceleration does not help and I have no other themes or extensions active atm. Just in case I've also tried updating graphics drivers to no avail.

Stable FF does not display such issue.

After installed some expired certs on a server in house, I try and bring up a management page that worked fine prior. The error is: The server presented a certificate that contains an invalid encoding of an integer. Common causes include negative serial numbers, negative RSA moduli, and encodings that are longer than necessary.

Error code: MOZILLA_PKIX_ERROR_INVALID_INTEGER_ENCODING

How can this be worked around, a setting of some sort maybe?

Thanks for any input

Hello,

I've been getting an error for some time now. Firefox tabs suddenly crash (usually media tabs with video, like Twitch or video conference sites) and I can't seem to find a solution. But most importantly, many videos or live streams show graphic artifacts. You can check it in the attached screenshot). I have tried many things to solve it, but none worked. This is what I tried:

  • Changing cables and monitors.
  • Disabling extensions and plugins.
  • Disabling hardware acceleration.
  • Installing Firefox from scratch.
  • Installing an old version.
  • Installing Nightly.
  • Removing the GPU. The issue persisted with a different video card and with integrated graphics. So the GPU is not the issue.
  • Trying using another OS. I thought my Windows install might have been corrupt, but it also happened in Ubuntu.
  • Trying other browsers. I tried Chrome (which resulted in the issue as well) and Edge (which surprisingly did fine, it's my only solution right now).

I would love to keep using Firefox but it's a pain to watch media like this. I don't know if the issue might be from the motherboard or another component. Between the crashes and this I can't use it normally.

I can try providing any details needed to solve the problem. Could you please help me? I don't know what else I can try.

Recently (a few days), I have noticed that math formulas are displayed as plain Latex code in a Moodle-based course viewed on my windows Firefox browser. There is no problem with other browsers and android devices. It seems to be related to the automatic update to the version 88 of the Firefox browser. Is any one else facing this problem? Does anybody know a solution?

Why must I suffer whenever a Firefox update is coming??? The same thing happens when Microsoft is going to update Windows. Everything slows to a crawl. At least monster Microsoft puts a little green dot on my power icon to let me know an update is on the way. Can't you notify me in advance, so I don't get caught in the whirlpool of everything slowing down? It even slows down my Microsoft Word. I didn't think my browser would affect that. PLEASE ANSWER. I thought you guys were cool alternatives to the big, commercial guys.

Since upgrading my OS to Big Sur (advice: don't!) some issues have arisen. Most printers don't work with it so avoid if it you can but regarding my browsing preferences:

1. I cannot now see Bing maps (which for all its faults I like as it has Ordnance Survey) 2. I can't create a new line of text in BT webmail. When I click return and try to type, it just refuses.

Any thoughts anyone?

Recently Firefox is randomly closing automatically after downloading a file from Yahoo business mail. This happens only with Yahoo business mail and not with other websites. So, when downloading a file from other websites (gmail, etc.) everything is O.K. This happened recently when Yahoo updated its software. Also, happens only with Firefox (for example with Chrome is everything O.K.).

Hi,

I have a problem with random "color blocks" appearing on the screen when using the Windows browser. They never happen with any other program on the computer so it is only an issue with the browser. These color blocks usually disappear when I roll the mouse arrow over the discolored block or reload the page. I have attached an image with an example, you can see the discolored black block when it is supposed to be all grey. I have tried both refreshing and reinstalling the software. The software has worked on this computer before. Any help would be appreciated.

Kind regards, Magnus

I have Firefox installed on an XUbuntu 20.04.2 LTS machine. preferences to "restore previous session" on startup. Intermittently, when I launch the browser, one of my windows has a very strange appearance (please note the general look of the window in the attached screenshot and ignore the "page cannot be displayed" message, as the screenshot was taken when I was not connected to the Internet.)

I have already tried reseting Firefox and that does not make the problem go away permanently; it always comes back eventually. (Note: I cleared cache before, and cookies after, taking the screenshot but before opening this support request. So the "troubleshooting information" attached reflects how it is after cookies are cleared.)

Hello.

I am using Ubuntu 21.04 and after the upgrade I got different issues with Mozilla products. FF is: 88.0 64-bit TB is: 78.8.1 (64-Bit)

One is: "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile." appears if I click on links in emails. It doesn't matter if they're linked to youtube, are an online version of the email etc. Always the same message.

I tried to assign Firefox as a standard browser and changed to another one, started the system again, ran Thunderbird and Firefox and it still happened. I tried changing something in the config editor, doesn't help at all. I checked for files / attachments and what should happen with http/https. There's no entry, which is fine according to mozilla help. The settings are the same as before the upgrade. I don't understand why it doesn't work anymore.

And second problem is: When clicking a email link in Firefox it doesn't open in Thunderbird. Error message is: "Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

It also doesn't work if I have run FF and TB in safe mode at the same time or in other constellations (FF in safe mode, TB not and vice versa)

Any other ideas?

Hi,

In the context of an app using Pixi.js to render markers on a map, we have noticed that Firefox is unable to load SVG images from a data URL, as soon as they have a width/height in percentage.

Switching to a px size fixes the problem.

But what bothers me the most, is that this fails seems to be silent, there is no way to catch the error and bubble it up to the developer. So the image just never loads in our code, which makes the issue extremely difficult to figure.

See more information, and a reproduction with Pixi.js there: https://github.com/pixijs/pixi.js/issues/7473
