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.

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

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

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.

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:

Automatically hide taskbar in desktop mode => Enabled Firefox => Maximised When cursor is moved to outer edge of screen, taskbar should unhide (Expected behaviour) but in this case it remain hidden (Reality). Firefox along with all other spinoffs give same result. Chromium based browser works perfect, and taskbar automatically unhide itself.

As OLED screen have became common as monitor, Taskbar auto-hide is must. If this issue cann't be fixed I may have to change my primary browser which I used for almost 15 years.

Kindly, look into it. If Chromium can do it, why not Firefox.

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'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

Hi,

First, this is not a complaint. Firefox is an outstanding product that makes me very happy.

I though I could post the following, because this community strives to make it better.

In a nutshell, I have a very fast Internet connection, up to 6Gbs/1Gbs speed, and Firefox is not able to go over .9/.8

I attach are 2 tests, one with Firefox and one with Chrome.

Note that when using it for anything else than speedtest, Firefox does not feel slow at all.

I'm not requesting a fix, just thought that somebody would like to know.

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

I am tired of this [removed] browser quitting, even when I don't have it open...I am going to uninstall it and NEVER install it again...I tried a full uninstall to see if it would fix whatever the [removed] issue with it was, but it is doing the same [removed] again!...I don't have this problem with any other browser I use on my system (Chrome, Brave, Opera and Tor)...I am tired of dealing with this [removed], so you can just take your [removed] and shove it!!!

How the hell does a browser crash when it isn't even being used???!!!

No need to respond and ask for any logs or other [removed], because it will all be gone!!!

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

1. Web pages load in gibberish, they aren't legible. 2. Web pages load with neon green blocks. 3. Firefox isn't allowing me to download an entirely new download.

I understand the gibberish could be a font problem but when I use right click for inspection options, I can't find any font info anywhere. Even if I could, what would I do then? Green blocks, have no idea. I used to use Firefox and have just now started again but would prefer a brand clean copy. Mozilla isn't giving me that option. Thanks.
