Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

No way to ASK a question in the Monitor section, there is no GET HELP button.

Application error: a client-side exception has occurred (see the browser console for more information).

In general, getting to the "ask a question" button in the support website is like finding hens teeth.

Didn't there used to be a Discussions forum, where you could see all of the questions being asked?

I have a slight problem. I'm currently using Firefox 116.0.3 and it seems that it can't update. The automatic updating will run, and then it will fail (this is all the time when using Firefox). It will recommend me to download the newest version from the website, but then the CDN will and I will be presented with the "connection was reset" error. This happens both on my Windows 10 and Windows 11 machines. Both are running Firefox 116.0.3.

Funnily enough I tried to see if I could download the newest version on Edge (Chromium), which it could but the version I got from the website was the same version I have now. I wonder if this is something to do with my region as I'm based in China and I'm aware that some software can have...problems.

Also, when trying to download version 122.0, it is fantastically slow and will often fail to complete.

Is there anything that could be suggested as I really don't want to use Edge.

Choppy 4K YouTube playback

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

I see where other people have posed this question but the procedure offered is not available to me.

I am using Firefox (Flatpak) version 121.0 on an Ubuntu 22.04 laptop.

On installing a new extension I should either see the extension's icon on my toolbar or else have a clear means of adding it. I have neither.

Clicking on the jigsaw icon in the toolbar, I get migrated to the about:addons page. On clicking the Extensions tab, I get the screen listing all installed extensions. Each extension has a ... icon beside it. But when I click on this, there is no "Pin To Toolbar" option.

What is wrong here ?

Firefox displays text on the .xml page as html code instead of rendering is as normal text. The layout and images on the page look as they should.

There is nothing wrong with the page, as it is rendered perfectly in Chrome.

In addition, this page doesn't display at all on the phone. When I click on the link it asks me to download it and then asks me which app I want to open it with - instead of simply rendering the page.

I have seen some old threads on this topic, it looks like this issue haven't been resolved for few years.

My question is not just about fixing it in my browser but at the root cause. This page is the RSS feed of my podcast which many people want to access and many use Firefox as their browser. Unless I tell everyone to use Chrome instead.

Can someone help? thanks.
