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 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 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.

Ever since the latest FF update each time I start/re-start FF I need to resignin to Dashlane. Honestly this hasn't happened in over 20 years. I haven't been able to find any similar reports. Has and/or can anyone explain why and hopefully provide an answer/work around? Thanks anyone/everyone.

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

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

Hello,

Clicking to open Firefox gives me the following error message:

Error. Platform version '120.0.1' is not compatible with miniVersion >= 120.0 maxVersion <= 120.0

Can't open firefox! I'm running Windows 11 version 10.0.22631 Build 22631

Thanks! Julie

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.

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

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

lately firefox has been freezing or without warning just shuts down. any special reason? according to 'about' it is most current at 94.0.2. i have refreshed and it still happens. i clear cookies & cache every night. no others use my wifi. i cannot figure it out. i am using W11, but i got that more than a month ago and only the past few days has this been happening. i am out of ideas on what could be the problem. any suggestions?

Like the title states, whether it be the search bar, url bar or any other text field the first key stroke of input is not registered and doesn't display. Once I've begun to type the missed stroke happens and then all is fine until I pause typing for around 30 seconds then the missed stroke happens again, otherwise I can continually type with no issues. This began a couple months ago and I assumed it was the old keyboard I was using so I bought a new one and the problem still persists. This issue is exclusive to Firefox and no other program or browsers on Windows 10. Firefox is fully updated, Version 94.0.2 (64-bit) at the time of writing this. I have "refreshed" Firefox and removed all add-ons etc. and the problem still exists. Thanks.

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

Recently I upgraded my Windows 10 to Windows 11 and since doing so, I've had consistent errors while browsing the web on Firefox. Most notably the "Humm. We're having trouble finding that site." error message.

For example, when visiting, say Verizon.com, the tab will display the aforementioned error to which I press Try Again and the website loads correctly every-time. No hiccups on the refresh.

I've tried the following:

1. I've performed a completely clean uninstall of Firefox and then reinstall
2. Cleared all browser history/cache
3. Removed all extensions
4. Disabled IPv6, HTTPS Over DNS, No Proxy
5. Ran through Firefox's troubleshooting
6. Used Firefox Troubleshooting Mode in the Browser
7. Tested that the problem does not happen while using Edge

I've never had a single problem on Windows 10 with Firefox. Curious if others are experiencing the same issues and if there are any fixes. Nothing else on the PC has changed.

• Windows 11 21H2 2200.348
• Network driver is the latest Win11 edition
• Firefox 95

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.
