Firefox Support Forum

Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

I can sign into YouTube ok, and the pictures of the video's are ok, but whatever I try to watch I get a green screen and just the video sound? It started happening yesterday. I am getting fed up with YouTube and the issues it has with Firefox. I'm having to use Microsoft Edge to watch videos. I've done the 3 resets it says on the support page, but still have the issue. Many thanks for getting back to me.

I have multiple monitors and most often have Firefox windows open on each. Lately, I've been noticing that the Desktop Window Manager process is consuming a huge amount of RAM. At the same time, consumption completely disappears with the closing of Firefox windows. Video: https://i.imgur.com/pHCa7Hh.mp4 (I left it for a while then closed Firefox windows) After a while, I noticed that already 13 GB of memory is being used by DWM. I don't know if sites affect behavior, but most often I have https://music.yandex.ru/home open

OS: Windows 11 (Microsoft Windows [Version 10.0.22621.1928]). Firefox: 115.0.1 (64-bit) Screen setup: 1 - 3840 x 2560 with 200% scale, 2 - 1920 x 1080 with 100% scale.

I am running Firefox v 120.0 (64bit) on Windows 10 Pro version 22H2 OS build 19045.3570 and today Firefox has stopped playing the video track on youtube videos or any video that is embedded in a page. Audio works but the screen just shows a blank field of green. The progress bar will show frames from the video. IF I run Firefox in trouble shooting mode the videos play as normal with video and audio tracks.

I have already refreshed fire fox and uninstalled and reinstalled it but the video track is still a blank field of green in both full screen and small screen modes.

Anyone have any ideas on what configuration setting may be causing this? Thanks in advance, Brocky

Intermittently (maybe 1/20 times?), when I try to do a Google search from the URL bar I'll get a tab that doesn't load for about 30 seconds. If I search for the exact same thing in another tab it will load instantly, and if I select the url and press enter it will also load instantly. I am seeing this issue both when entering a search and when selecting text and clicking "Search Google for X".

I found a recommendation on a similar issue to set security.tls.enable_0rtt_data = false in about:config but I have seen no change with that setting.

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

Hi,

After updating Firefox to 116.0.1 my tabs keep randomly crashing. I get some crash reports *occasionally* - meaning not all crashes produce a crash report - but I'm not sure what to do with them, they seem inconclusive. The last report (not for the last crash, though, which didn't produce any report) is bp-3334b934-58b5-4226-887a-235300231117

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

This problem started with an update a couple months ago. Each bar is about 4 pixels wide and appears only on the right, left, and bottom edges of the browser window. They persist when the window is full size or smaller, but disappear on f11. The bars are completely unresponsive. Clicking or resizing the window doesn't seem to work inside of them. Even though the top of the window has no visible bar, there is still an unresponsive region like the other three sides and approximately 4 pixels of empty space.

When it comes to color, the bars spend about 50 percent of the time as white and 50 percent as the same gray that Firefox's dark mode uses. I wasn't able to get a screenshot when the bars were gray, but I was able to screenshot the top right and left corners when the bars were white, which I have attached.

It appears as if there are buttons of some sort poking out on the top right and left corners. If I had to guess, the top right icon looks like the "x" button on a Windows 7 window, and the top left icon looks like the red dot in the uppermost corner of a macOS window. My machine has only ever run Windows 10, and Firefox is the only application that this problem occurs in.

Restarting, using troubleshooting mode, manually removing extensions and themes, messing around with compatibility settings, running as administrator, refreshing Firefox, and reinstalling Firefox have all been unsuccessful. It really is annoying to live with this bug.

Windows 10 desktop user, Firefox says that it's up to date.

Background information: After running normally for most of yesterday, my computer entered sleep mode while I was having dinner and then had some sort of trouble coming out of it, forcing it to restart entirely. Only Firefox and Discord were open at the time the computer entered sleep mode.

Upon restarting Firefox, however, I noticed that my tabs were loading unusually slowly even after they had allegedly finished - switching between tabs often results in white screens with the circle in the middle of them for several seconds, and there is noticeable lag when attempting to open links or type in the search bar, among other things. This problem has persisted after restarting as well as shutting the computer down entirely before rebooting it.

Troubleshoot Mode made no noticeable difference, nor did clearing the cookies and cache afterwards. However, in my subsequent attempts to relog into several sites afterwards, I was unable to do so for both Google (via Youtube; the saved email fills properly but it will not proceed to where you'd normally enter the password) and, ironically, the mozilla/firefox websites itself, which claims I do not have cookies enabled.

(Which means that, embarrassingly, I've had to use Edge just to login here and ask this question...)

All the other websites that I've tried to login to have worked, though, so I'm not sure what's going on.

Can anyone help me?

fresh install RHEL 8.5 FF 91.2.0esr

i start a vid in youtube. the sound has static. if i open another window, even on a site that doesn't play video or sound, the sound and picture on the first window instantly get out of sync. the picture runs about 2-3 seconds ahead of the audio.

i have not customized the setup. this is a "stock" configuration. i have lots up upload, download speed. 20Mbps up, 80Mbps down.

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

Here's a link to the latest crash data: https://crash-stats.mozilla.org/report/index/1389c870-51cf-4790-b0a0-fd01f0211202

Every time I play this online game at the site, Wormax.io, it will lag and/or crash the tab after a few minutes of playing. Occasionally, the site will take a very long time to load.

Here's my crash report: bp-4fd287ff-c2e1-4168-8e9d-ac1950211202

On certain pages, the rendering is completely off. For example, on Vimeo.com, all the text is gone (see attached pics). I tried Refresh Firefox, but the problem persists. I tried Troubleshoot Mode and that fixes the problem. But when I restart and disable all of my extensions, the problem continues.

This only happens on my work computer Firefox. The Firefox versions at home on multiple computers work just fine.

Any thoughts?

For the past couple of weeks I am not able to log in to AA.com. When I fill in the require fields ( AAdvantage # or username, Last name, Password), it redirects to https://www.aa.com/sorry.html. I have no problem logging in on one of the other major web browsers. Ad blocker is turned off, cache has been cleared, all the tricks that usually solve such problems. So, I'm beginning to think that something in a recent Firefox update doesn't play nice with AA.com. I'm using Firefox Ver 91.0.2.

Any suggestions?

After Windows 10 update today, Firefox 94.0.1 too slow on msn.com. Cleaned files, defragged and no help. Windows 10, Roboform, and Norton 360

I downloaded bing themes . when I try to open Firefox, i get this in address www.msn.com/?pc=W099&ocid=MSNHP_W099. and it is buffering and will not open. I deleted the bing download, restarted the PC (Dell laptop) and still the same problem . I checked the settings and Firefox is the default. what can I do? I just want the Firefox homepage back.

On Startup: - "Open previous windows and tabs." Yes, I have this checked, but it ain't actually doing it. What's the solution?

True or False? If this box is checked I can quit Firefox altogether which tabs still open, and those same tabs will automatically load again upon reopening Firefox.

(Upon writing back, please refrain from thanking me for anything.)
