Firefox Support Forum

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?

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.

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.

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

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?

When I use google meet, I regularly get feedback that I sound far away, despite being at a normal distance from my computer. If I switch to another app, like slack, the issue doesn't present (so it's not an OS level issue). I'm using firefox on m3 macbook pro.

What can I do to fix this issue? Or do I have to stop using firefox?

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.

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.

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

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.

Hello! I updated FLOORP on the 5th May, FLOORP crashed and then Brave, Firefox, Waterfox, LibreWolf and Vivaldi started crashing. I had Brave and Vivaldi open when I launched FLOORP and FLOORP asked consent to update itself and after updating, it did not open in “previous session” and I could not open “previous session” through History. When I launched “Settings” from menu, “previous session” opened! I had pinned “Settings” earlier.

Now the bizarre happens; suddenly LibreWolf launches by itself also without “previous session” and open tabs in Brave and Vivaldi disappear to single New Tab. After some tinkering, I was able to restore “previous session” in LibreWolf, Brave and Vivaldi.

Now I close all browsers and open Firefox, no “previous session” and some random windows in its history, opening these random windows also opened “previous session”! 🙄But then Waterfox launches also without “previous session”, here clicking on OneTab extension recovered “previous session”.

Cutting short; I uninstalled, Waterfox, LibreWolf and FLOORP, this did not help, I ran System Restore twice to two different points and it has not resolved the issue.

Thankful for any help!

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.
