Support,

The USPS website does not work properly with Firefox!! The Home page loads okay but there are multiple other issues with links not working. For instance all of the links under Quick Tools do not work except this one: https://www.usps.com/manage/po-boxes.htm. Other things don't work either.

Everything works fine that I tried with Google Chrome though! Please address soon.

Thanks

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

Every time I open Firefox, it crashes immediately and does not trigger the crash report window. Even though I have checked and enabled the option to send crash reports in the settings, it doesn't work. When I look for crash report logs, it shows that I have not sent any crash reports.I've tried many methods to view the crash report, but it just shows that there are none. I only found this information related to crash reports in the installation files.(you can see it in the picture)，hope someone can answer this question, thank you very much.😭

Hello, I have a weird bug with the firefox browser causing weird graphical glitches only on the main screen when a HDMI cable is plugged in on the duplicate mode. I have found that is is only on firefox and not my desktop or any other programs. Firefox is up to date and the issue is fixed when the HDMI set to extend

I hope you find out why this is happening and fix it swiftly Thank you -Dominic

There is a display issue when I search anything in the url bar. It goes up the window, and disappears completely if many suggestions are made. The issue disappears when in troubleshooting mode. I disabled all plugins, changed the theme to no avail.

Today I noticed that typing characters with accents like á, ã, â, etc. doesn't seem to work at all from firefox, they all end up ignoring the dead key and just typing the letter itself. It can render them just fine and I can paste them from another app normally too, but actually typing them is impossible from firefox.

After trying to troubleshoot, I eventually found out a few things: - iBus is not at fault, since it works in every other app and I even restarted it, but the problem persists - This only happens in my main profile, newly created profiles don't have that problem - The problem still happens on troubleshoot mode (as long as it is my main profile) - Compose key also doesn't work (I don't want to use compose key anyway, because my keyboard has specialized dead keys, but I at least tried it)

I suspect the problem lies in a setting on about:config that's different from newly created profiles, but I have no idea which and Ctrl+F searching this site doesn't show any relevant configuration that might be the culprit.

There is a problem logging into Disqus. (disqus.com and disquscdn.com)

This is affecting Linux and Windows installations.

Page I'm having problems at www.lawyersgunsmoneyblog.com

I have used the troubleshooting mode and caches have been cleared and all extension disabled with no luck.

Other browsers are functional. The log in doesn't appear at all:

I'm up to the most current version of Firefox

120.0.1 (64-bit) Windows 11

For this and the last versions over a couple of years whenever I go to;

https://www.linkedin.com

Then try to go to any other page like https://nextdoor.com from a bookmark, it stays on linkedin.

If I enter the address by typing it in, it works.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

Hi. i have no results while doing this: https://dpaste.com/FTXPQ46ZL# No error, no screenshot. "Screenshot" flags in default state, about:policies - inactive.

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Device: Surface Pro X SQ2 OS: Windows 11 Home for ARM (Up-to-date at time of writing) Firefox Version: 125.0.3 (AArch64 up-to-date at time of writing)

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.
