Firefox Support Forum

bold textExperienced Firefox browser session freezes a month or two ago. It seemed that some March/April '24 fixes/patches stabilized the app. They are occurring again with increased frequency. What should I do to avoid this problem or switching to another browser? Thx

Well, since I changed to a new computer with Win 11, videos on Facebook don't play right. They are videos that are posted by various people and real entities. They are not smooth. They start to play and immediately pause then jump forward then pause and jump forward. If I copy the link and go to Chrome, paste the link and play the videos, they are normal Never did that on my old computer. Any ideas why the videos don't play normal?

Windows 10. Weird glitch.

If I use Wondershare UniConverter's downloader function to download a video, as soon as the download starts, all Firefox open windows close. This is a recent thing, the last couple of weeks or so. I have reinstalled Firefox and UniConverter. The first time I tried it after reinstalling UniConverter, all was well. But the same issue has shown up again. I have tried rebooting my PC to no effect.

Any bright ideas welcome!

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

The webcam video image is being reversed or being flipped horizontally when using the latest version of Firefox. This is not happening in other browsers. I reset Firefox, but the issue still occurs. Can you advise/fix please?

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

I just did the most recent Windows 10 updates:

KB5037768, KB5038350, KB5001716

My version is 22H2 for x64 and .Net 6.0.30

Upon finishing the update and rebooting, Firefox gave me the PR_CONNECT_RESET_ERROR on all websites. Not other browser was having an issue. I've tried all the troubleshooting steps I can find. Is there an error fix based on what I am describing that I can now try?

Thanks!

Every time I start up firefox, it takes about a full minute to load. It shows an outline of the UI, but does not become usable for a while, windows also puts up a "firefox is not responding" window when the window is interacted with. After loading, opening a new window is unaffected, and page loading is snappy. just the initial launch is the issue. This remains true even after a clean uninstall + reinstall. Appdata folder was removed as well, and did not affect the issue. I do not have any antivirus software other than windows defender, so that should not be an issue. My hardware is also not likely to be at fault, as it is sufficiently up to date (upgraded within last year, not sharing specs here). Chrome starts up in less than a second for reference. Once again, a fresh install with a new profile has the same symptoms. Have tried every available guide to no effect.

So yesterday I downloaded a bunch of files to mod a game. This warning appeared and since then it's been popping up every time I start the browser. I have cleared all cookies related to the relevant sites. I have removed the warning about unwanted and uncommon software. I would rather not clear all my cookies and data to resolve this, so looking for other suggestions first. I don't mind digging through files or code to make it happen.

How do block a fake recurring alert?

Hi, not sure the best place to ask, but it's been an ongoing issue since 2022. I kind of believe a shift in Intel has caused some of these issues, but probably not important (and I've already contacted them and did not get anywhere) at the moment.

Essentially, having Firefox running crashes the Intel UHD Graphics system, typically it is the UHD 620, but I believe I have some systems with a UHD 630. On Windows, I get a blank screen for 1.5 seconds, on macOS it crashes the entire Mac. I...I have a hard time wrapping my head around the fact I'm the only one with the issue and has occurred on multiple computers over a period of 18 months. The systems in question include the following:

Dell Optiplex 5040 MT - Fixed by putting a GTX 1650 in its 16x slot. Dell Optiplex 5060 MFF Dell Latitude 7290 Dell Latitude 7490 MSI GF63 (9th generation revision) MacBook Air 2020 w/ Intel i3 under macOS.

The thing is, with the exception of the MacBook, PCs don't report any issues apart from a "Hardware Failure" within the Reliability Monitor and the aforementioned screen shutoff. With World of Warcraft I'm able to reproduce the issue consistently under both DX11 and DX9, but Firefox not so much. I do see it occurring only on YouTube videos on the MacBook and is more common to occur on PC, but I have also had it happen on normal browsing.

I can turn off hardware acceleration and have done so, but I do wonder how much of an impact it will make on power efficiency on say, battery power. Would be something that should be fixed and I would like to put effort into getting it resolved, but I have no idea where to start. All drivers are up to date, Intel Boost is disabled (and I wonder if having it set as so causes this, though the MSI has no such BIOS setting) and it only occurs on Windows PCs with Windows 11.

Thanks for reading.

Hello,

I've been experiencing a great deal of crashes recently, mostly just with individual tabs, but occasionally the Firefox window itself goes down as well. I've tried reinstalling and refreshing Firefox, and I've been doing checks to see if my RAM or other hardware are faulty with no results so far.

I've mostly experienced the issue when playing videos on YouTube, but I've had crashes just casually browsing other sites as well.

Any insight would be greatly appreciated, and thank you in advance.
