Diễn đàn hỗ trợ Firefox

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.

This is pretty shady Mozilla.

When disabling only one setting: "Allow Firefox to install and run studies" it wrecks this site whether logging is or continuing as guest:

Even after logging in and everything running normal, disabling the studies run by Mozilla and a quick refresh breaks the functionality of the page. All cookies were accepted and the sharing of location was allowed. On a fresh, first run, wide open Firefox people. Literally, the only change that was made was unchecking that one box. In disbelief, i tested it over and over.

Why would disabling a telemetry setting, something that should be optional, cause this to happen? Seriously, what could possibly be the reason. I'd love to hear it.

This was the final nail in the coffin to me and this is since the 0.9x days.

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.

All of a sudden for the past few weeks or so, I keep getting the message in the attached screenshot when entering words in the search bar and clicking on Google. This never happened before in all the years I've been doing this, so what's up with it and can it be fixed? Thanks.

Not sure why, but Gmail is not loading, then Ebay shows gmail pic broken, and can't log into ebay either. I can log on bot via private window tho I have removed all ad-ons, uninstalled adblock, still no go, this happen with Some of the Firefox updates, but different sites. Thanks

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.

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

Hi,

for some time now I can't use Grok(x.com) in Firefox(137.0.1 (64-Bit)) anymore. "Something went wrong" is always the answer.

Troubleshooting Mode doesn't help. Disabling any site restrictions, neither.

Any one else? Any ideas?

Cheers
