Firefox Community Forum

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

For a few days, for unknown reasons I have been unable to access my blog..."Kitchen Connection". This has never occurred before, and it is very annoying. I have been blogging for many years.

Your assistance in this matter would be appreciated. Thank you in anticipation.

I've tried submitting the above a few times...and for whatever reason, it has not gone through to you, it would appear.

Anything using WebGL in-browser tells me that my browser doesn't support it.

https://get.webgl.org/ says "Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card." but I updated it to the most recent drivers and the issue is still happening. Graphics card is an AMD Radeon RX 6600 XT.

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

It looks like some sites are not working properly, two examples I can give are google sheets&docs, in the attached image you can see my sheets are not being shown, note that if I directly access a sheet's link it does open.

The second example is some websites with media players just load infinitely (YouTube works).

Also added network tab non 200 status code requests images.

Things I've tried:

• Disabled "network.dns.disablePrefetch".
• Tried troubleshoot mode(meaning those requests that were blocked by ublock are not the problem).
• Deleted history including cookies.
• Private Browsing.
• User Agent masking
• Reinstalling

After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

Since Friday i cannot log into my Quickbooks account using Firefox. All other browers work fine when trying to log in. My default browser is Firefox. SO this is totally frustrating.

The error message i receive is:XML Parsing Error: no root element found Location: https://accounts.intuit.com/app/sign-in?app_group=QBO&asset_alias=Intuit.accounting.core.qbowebapp&iux_tests=49561:8:119104&state={%22queryParams%22:{%22locale%22:%22en-us%22}}&app_environment=prod&locale=en-us Line Number 1, Column 1:

Hello, vinted.com/ vinted.co.uk has been throwing me all sorts of strange errors and security concerns over the past 4-5days. Any ideas? Thanks for your help!

Hello, I have all of a sudden having issues using We Transfer to download files in Firefox. It stops short of the full file, but says it is downloaded. I contacted We Transfer and they asked me to use the private window option. I did that and it worked. I told We Transfer and this was there response.

Incognito mode works without extensions, so if it worked in Incognito and not in the regular mode, please try to disable all extensions/firewall/ad-blockers to see if it helps with the normal mode.

I don't know how to find these in Firefox to do this.

Please help me.

Thank You,

John Davidson

I recently updated Firefox Linux on Chromebook and now when I open a Google Doc it displays fine and I can place the cursor with mouse but when typing no characters appear in doc. I checked Firefox on Windows and it edits same docs fine.

When I search using duckduckgo within firefox I get a white page with no results sometimes, it's quite frequent and I'm not sure what is the cause. I've tried disabling addons like Ubo, malwarebytes and had no luck. I've changed my firefox settings hoping that would fix it but it hasn't. It's like the page doesn't fully load.

Trying to connect to yahoo mail (currently.com) and keep getting error messages. All other websites on firefox work.

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.
