I am using Windows 10 Enterprise N, Version 21H2 and installed the Media Feature Pack through the Optional Features tab. But even though other browsers have picked up on that and can play e.g. Twitch streams etc. appropriately, while Firefox still shows the `this video is unavailable or not supported in this browser` error message.

Hi there,

I upgraded my Mac Desktop OS to Ventura 13 yesterday and now my Firefox browser is not working. It opens very briefly and then the window closes immediately. The Firefox program is still open in my dock, but when I click on the icon, the Firefox window only opens for the briefest moment and then immediately closes again.

I tried to fix it: I have uninstalled and re-installed the latest version of Firefox twice and have rebooted my computer twice.

Has anyone has similar experiences and/or ideas for solutions?

Thank you!

People are having connection issues on firefox https://www.reddit.com/r/firefox/comments/x1um0o/browser_problems_after_1040_and_10401/

A fix for this is going to about:config

network.dns.disableIPv6 and set to true

Disabling ipv6 is a fix, but is this safe?

I think mozilla team should look into what exactly is making ipv6 cause connection issues.

Vimeo videos freezing on fullscreen

I've recently been having troubles playing videos on Firefox.

My school website uses Vimeo embeds, but recently when I've put the videos in fullscreen, after 4-5 seconds it stops responding. The video freezes but the audio continues, and the controls don't come up when I move the mouse. I can press ESC to exit fullscreen, but the controls are still gone and the audio keeps playing. Then after a few more seconds I get the warning "This page is slowing down Firefox, to speed up your browser stop this page".

If I don't use fullscreen but instead zoom in on the page, it also freezes. If I try the same things with Edge it does not freeze. I also made sure that it was only affecting Vimeo videos, by testing with other platforms and other vimeo links.

I found previous reports of this issue, but all of them were either on Linux, or it was an issue with flash player, which is not relevant anymore.

Not quite sure how to debug this but I would be happy to provide further info. It's really important that it works again :/ Thanks in advance!

My repro steps: 1. Find a video on https://vimeo.com/watch 2. Play it and enter fullscreen 3. Wait around 6 seconds

I seem to have that bug that was fixed a few updates ago where videos won't play. I have the latest version of Firefox. For example, YouTube will load and the page, progress bar and even subtitles will show, but the video will just have the spinning circle. I have tried videos on other websites (Facebook, Tumblr) and they won't play either.

I've uninstalled/reinstalled Firefox, refreshed Firefox, disabled all add-ons, allowed autoplay of videos/audio but nothing works. The videos all work on Chrome and Edge.

Yo guys what's up! Been having problems with Firefox for several months now, restarts make no difference. Getting huge CPU drain if I have any Twitch tab running. Above screenshot is in troubleshooting mode (all my addons disabled) and a single twitch tab open. It makes my whole system sluggish especially if I happen to have something a little demanding in addition to the stream open. Chrome does NOT do this at all, much more balanced drain.

Specs:

HP pavilion laptop 16 gb ram core i7 chip bottom of the barrel nvidia mx250 GPU

The other screenshot is a comparison to Chrome. Both have a SINGLE tab open with a twitch stream playing. Firefox is using almost quadruple the resources, AND its in troubleshooting mode.

Hope you guys can help me out, been a long time Firefox user since I was a kid and really don't want to switch browsers.

The new version of Firefox runs very slowly, tabs take long time to load and is slowing down other operations on computer while waits for mouse to re-appear etc. Had downloaded a previous version, then firefox automatically updated and back into sheet mode. Now your ridiculous download previous version page is very much less than helpful as just keeps trying to get you to load newest (crap/buggy) version. Uninstalled firefox and computer works well again. I've used firefox for long time, but will change to something else if cant access a download for previous version that allows better operation while wait for a perhaps better working newer version. Learned lesson with windows updates over the years, not gonna use your current version of firefox.

I love Firefox but it has a market share of just around 7% and is even lower than Edge (which is terrible IMO). Chrome has the most users at around 65%.

Although Firefox is a much better browser, the perception for many is that Chrome is better due to much faster browser loading. I have Chrome and Firefox installed on Windows 11 with the same extensions and Chrome loads my home page in 2 sec whereas Firefox takes 7 sec to load. Even after deleting all cookies, cache and web history, Firefox still takes 7 sec to load my home page.

It's great to prioritize security, flexibility etc and I love these aspects of Firefox, but by not doing something to improve the awful loading times, you are leaving users with the impression that Firefox is inferior and LOSING the browser battle.

Hi, For about the last month or so, the Yahoo mail tab closes itself after I click on an email attachment to open the download dialog box. This happens exactly 30 seconds after clicking on the attachment, whether or not I go on to open or save the attachment. It does not happen if I merely 'preview' the image. I don't know if all attachment types behave the same, but it applies at least to jpg and pdf files. The tab can be reinstated via History/Recently closed tabs.

Firefox does not crash, and there are no crash reports. In other respects this is similar to a previous post by 'eladopoulos' on 4/30/22, 8:17 AM (https://support.mozilla.org/en-US/questions/1375635).

Using Safe mode makes no difference. I had set browser.download.improvements_to_download_panel to False, but reseting to True makes no difference. Thanks in advance.

The satellite imagery on google maps is mirrored diagonally, while the road map displays correctly over it. Win7, Firefox 108.0.2. started happening with Firefox 107.x.x and tried resetting Firefox, but no luck. Satellite imagery displays correctly in troubleshoot mode and private browsing. Cleaned out my cookies and cache, but no dice in regular browser.

Anyone have experience with that?

For the last few months (perhaps concurrent with a Firefox update, but I don't remember), Firefox seems to be having problems with Google-sourced stuff. It's intermittent, but the most frequent failures are searches using either the address field or the dedicated search field - much of the time I just get a blank page, and at first it looks like it might be trying to load something, but after awhile the "X" abort icon changes to the reload icon, signaling that it thinks it is loaded or has given up. Success or failure seems to come in waves or phases, not completely random - immediately retrying will usually not work. If I can get to the Google home page by typing "google.com" directly (which has a much better batting average than searching in the address/search fields, although not always), I can search directly on the Google page without trouble for some mysterious reason (perhaps that fills the page using AJAX rather than reloading - I'm not sure). But then clicking on one of the results might not work, because that initially goes to a Google URL before redirecting to the requested page. I've resorted to extracting the page location from that redirection URL just to bypass Google.

Other Google services have problems, too. YouTube's home page usually loads outlines of videos, but sometimes it fails to fill in thumbnails and other details or does so VERY slowly. Occasionally even reCaptcha will fail to load when I'm trying to log into some site that uses it. And even when something appears to fully load and function (e.g. a couple Google Sheets I use daily), often the "stop loading this page" X and hourglass on the tab will remain, indicating that it thinks something is still loading (in that case, it seems to never time out - I either click the X or ignore it). All these types of failures started at the same time, so they seem to have a common cause.

I have not noticed any problems with sources that are not owned by Google. And Chrome and Edge have no problems at all. So apparently it's specifically Firefox and Google that are not getting along. I'm running Firefox 108.0.1 (in PortableApps, although located on my hard drive) on Windows 11.

These failures happen even if I start Firefox in troubleshooting mode (which proves it's not caused by an add-on) or open Google in a private window so that there are no cookies involved. Since Chrome works, I also tried using the User-Agent Switcher add-on to pretend I'm Chrome, but that also has no effect. I expected to see tons of other complaints about this on the web, but there have been surprisingly few, and the only suggestion that seemed relevant (and effective for some people) was to set "security.tls.enable_0rtt_data" to false, but that has not made any noticeable difference in my case.

I waited through a couple Firefox updates, hoping it would just get well, but I've lost patience. Are there any new ideas out there?

Okay, I'm not terribly upset by Firefox opening multiple processes. I have a 16 core CPU and 64GB of RAM with everything running off SSD. HOWEVER. Firefox is opening 15+ processes. When you have that many, Windows AUTOMATICALLY shoves the last 5 into "Efficiency Mode".

EVERY TIME!

This behavior has only become problematic recently. With the "live" tabs that I'm actually using being the stuff forced into efficiency mode.

Hi,

After an update, Firefox does not recognize middle click at all. It worked in the past, but no longer. For example, middle clicking on... - a hyperlink should open a tab in the background - a bookmark bar item or bookmark menu should open that bookmark in background - empty space on the webpage should initiate autoscroll - a tab handle on the Firefox title bar area should close that tab None of these work as of now.

I'm on Windows 10, and I am using a Logitech MX Master 3 via USB Unifying receiver. I checked Logi Options+ app and confirmed the middle button is correctly set to middle button (default) and there's no per-app settings for Firefox.

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?
