Firefox seems to freeze up after a while (the duration seems random) when there is a tab with video content playing. The audio can be heard to be playing, but the video does not update and the browser UI itself is unusable. This seems to be a new issue since Firefox 90. I have tried refreshing Firefox, but that did not help.

My add-ons are Bitwarden, uBlock Origin, Decentraleyes, Privacy Badger, Auto Tab Discard, SponsorBlock, Nuke Anything, and Facebook Containers. My about:support is at this Pastebin link.

Hey, I have already read the other (closed) forum topics. I have the problem, that on some websites all letters from s to z aren't displayed. When I copy the text and paste it to a text editor all letters are there.

Here's what I tried according to other forum topics... - In the font properties all is set to standard fonts for 'latin' and 'other' (sorry I use Firefox in german so I don't know the correct english terms)

- Disallowing webpages to use their own fonts works, but it's no option as the websites now all have ugly fonts and don't look as they're meant to be.

I use FF 90.0.2 (64-Bit) on Windows 10 Home.

The problem occurred right away after I installed FF on a new computer. I have also tried syncing to my account and de- and reinstalling. Same problem all the time. The problem does not occur in other browsers, like Chrome, Edge, Opera. Only in FF... Any idea what I could do? It would be sad to use another browser in the future, but since I'm also a web developer it's really not an option to work like that... Any help is highly appreciated.

Cheers, Sven

I have been automatically updated to 90.0.2 on several machines (most 64-bit Windows 7), but there appear to be problems with the latest version. I can't see evidence that these have already been reported.

1) Window update. When the browser window comes to the fore (top of the z-order), or when resurrecting from a minimized state, it does not redraw the whole window. Usually, half is missing. However, a cursor-move event while over the window triggers a redraw.

2) I have just experienced CAPTCHA issues trying to get into an gov.ie website. Instead of showing me text to enter into the field, it just showed a gray square. However ,the same challenge works OK in Chrome (i.e. it's not a problem with the site itself).

Are these known issues? Is there a way to regress to the previous version?

Since my firefox browser updated yesterday with the July 19, 2021 update, some web pages are not displaying properly. For example, I use Yahoo mail, and when I click on an email, most of the content is not showing, including the sender's message. Other frequently used websites are similarly affected.

This same problem occurred after another recent firefox update, and it was eventually fixed when I "checked for updates".

I'm hoping this bug is widespread enough that the Mozilla team will be providing a further update that fixes this.

Meanwhile, if anyone has an idea, I'll listen!

I have been using Firefox for a number of years.

I primarily use a Sony Vaio PC using Windows 7.

I got an automatic update of Firefox Version 90.0.2 on 7/22/2021.

It is not working very well. Opening new tabs are hard. Will not close tabs very well, leaving unused space on top. Different sites show up on another sites tab. Worst of all, this new version is a memory hog, with me eventually having to reboot the PC to clear memory until the next time.

Can you please help?

Thanks in advance,

After latest update to 90.0.2 I'm no longer able to log in to an internal corporate website. This has worked fine before. Accessing the same site with Chrome or Edge still works fine but no longer with Firefox.

Error message: SSL_ERROR_CERTIFICATE_UNKNOWN_ALERT

I have previously struggled with Certificate with Firefox but after enabled security.enterprise_roots.enabled in Config it has worked fine until now.

So what has changed this time and how to bypass? Obviously the cert/website works fine with other browsers.

Thanks Henrik

For the last couple of months I've been having an issue with Firefox freezing when I bring up a news article on Yahoo. It only happens when there is a video attached to the article, the video and the text of the article won't load. After a few minutes there is a message saying "This page is slowing down Firefox. To speed up your browser, stop this page". All of the Yahoo news articles work fine when I bring them up in Chrome. How can this be fixed??

I have Firefox on a couple of (Windows 10) PCs. This problem is happening on one of them. It has two profiles (users), and it's happening on both.

If I open Firefox, and then trying going to google.co.uk, or do any google related search, almost everytime there is an obvious 30-40s delay. Indeed, during this time I can even open up other web sites (immediate), and trying google.co.uk again, and delay continues to occur.

Opening up the Network Console in Firefox, the GET request can be seem and then like clockwork there is about a 41000ms delay until it then continues.

If I open in TroubleShoot mode, same issue.

If I open in a Private Window, the problem does NOT occur.

This problem does NOT happen on my other PCs with Firefox, or any other browser on the PC in question.

This is very frustrating :( You open firefox to do a google search and it takes tens of seconds to resolve (on the first attempt) :(

I am using linux kde neon on wayland. Firefox version 90. On ubuntu with gnome 40, my touchpad zoom works. I didn't have any problems on kubuntu either. But on Kde neon, gestures don't work. I forced the MOZ_ENABLE_WAYLAND = 1 setting to enable wayland support. About: support shows that wayland is supported by the browser. Also I tried the settings MOZ_USE_XINPUT2 = 1 and GTK_USE_PORTAL = 1, but they didn't help either. Gestures in the system itself work.

Since a couple of weeks my Firefox browser for Windows 10 64bit has issues. Last update 90.0.2 did not work either,and the issues is still there.

Internet is extremly slow,some sites will not open and i cant logg in to Facebook.

Under settings,i have tried different settings. Right now i have the standard setting. Under Help,i have tried to restore,diagnos and clean catch and restart,but it has not solved the issue.

What could be causing these issues? Do i have to do some special settings or do i have to add some Add-ons/Extensions in order to have Firefox work normal again?

When I open Google Maps it doesn't show the normal icons for navigation on the map. It doesn't do anything when I have hardware acceleration enabled and I type something in the search bar. If I disable hardware acceleration it does a search, but in no way can I get it to show the place I want to see. It just shows the map of Rotterdam, where Google thinks I live based on my IP address.

It does work in Safari though, so it's a Firefox problem. I hope you can fix it. Google seems to give the FF team lots of problems.

when embedding a bigger video in firefox i got audio bugs. It crackles like an old movie. No problems in Chrome.

The video was converted with VLC to MP4/MOV with H-264 video and MPEG audio codecs. Because of its a very high quality video, the file size and Bitrates are very high. Is it possible, that firefox has a problem with that?

I know, usually you should never offering a video with that size on a web template, but its local hosted for an kiosk-mode project.

Example File:
