Diễn đàn hỗ trợ Firefox

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.

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!

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.

This address uses a network port which is normally used for purposes other than Web browsing. Firefox has canceled the request for your protection.

Recently I have been unable to log into Reddit. Firefox is up to date, cookies and cache has been cleared, ublock origin has been disabled, still doesn't work. I can click 'Log In', enter my username and password, and then it is impossible for me to click the Log In button to advance. Left clicking the button, pressing enter, pressing tab until it is highlighted then pressing space, none of these work. I can open Edge and log in no problem. What do I need to do to fix this?

I got a Firefox update recently and have not been able to access Flickr since then. I am getting a message that the page is not redirecting correctly. I am attaching the error message. I am running with standard firefox protection. I have cleared cache and cookies. I have also added Flickr as an exception to Firefox enhanced privacy tracking. Firefox is up to date (version 134.0.1 (64 bit)). Anyone else having this issue or know the solution?

I am unable to get access to my Gmail accounts. Every time I select a bookmark link to Google email I get server time out error pages. I have looked at Windows 10(64) Firewall settings and I do not find anything blocking Firefox from accessing the internet(Inbound or Outbound Rules) are set to allow. NordVPN is not set to block any program or connection. I have never seen anything block access to Google.com or any related pages within Google. HELP Please!

Today I've noticed some horizontal lines on youtube videos. Upon further investigation, I've traced it to a single div element:

The base64 encoded image is the lines I'm seeing.

Initially after starting a new private session and navigating straight to youtube.com I had no lines. Then in that private session same element doesn't have an image:

What's odd about this is if I opened a private window and copy pasted the same video URL I would get the lines. After testing multiple times I started getting the lines even after navigating straight to youtube.com.

So I did another test: changed my IP with a VPN in a private session. Navigated straight to youtube.com, watched multiple videos without any lines. Then I logged in to my account and boom, the lines are back...

Opening the same video on google chrome browser I get a smooth gradient line image:

The browser is functioning as intended, but youtube is intentionally making their website unusable. What the f###? I have youtube premium, adblocker disabled on their website.

I have had multiple sites ask me to disable my ad blocker. I can't find an ad blocker in my extensions. Badger, which I do have, says it is not an ad blocker! Some of these sites, such as Rotten Tomatoes, are sites I use frequently! Help!

Hello, everytime I try and upload a video on YouTube with firefox, the video gets stuck at 0% processing,

This never happened in my 4 years of youtube and recently (a few weeks ago) this starting happening. I use firefox to stricly upload videos, and use chrome to browse with my other account casually.

Now Im forced to upload using chrome but I want to still use Firefox to upload videos. anybody know why this is happening? I've cleared cache serveral times and it still won't work. I have no adblockers etc.

On Feb 13th I went to my website at MyHeritage.com, to which I'm always logged in, to find that a few seconds after it loads it becomes all greyed out and I can't access anything. I had been on the site a couple of weeks earlier with no problems.

I removed the "Enhanced Tracking Protection" and I turned off AdBlocker for the site but the problem persists. I have logged out and then logged in - same problem. I turned off my computer and restarted it - same problem.

When I went to log in to my account at MyHeritage using my Chrome browser I encountered the same problem of a greyed out page BUT there was a banner stating something about cookies and when I clicked the "I understand" button the greyed out page cleared and I was able to access my account.

However, Firefox is my default browser and I want to be able to access this page using Firefox. It seems to have something to do with cookies.

For whatever reason, when I open certain websites in Firefox, it shows the prices in UK currency including VAT, but when I open the same websites in Chrome, they show up in US currency. The Windows region setting and the VPN connection is the exact same for both. The difference is the browser.

Is there some setting in Firefox that makes it think I am in the UK, and if so, how do I change that?

Hi team, I have created a web application using angularJs(angualr 1) and html in which a web page displays google map.it is working perfectly when we open in Firefox and chrome browse. I have created a wpf window application using .net framework 4.6.1 and embedded geckofx control to render web pages from web application .Issue is that google map is not rendering in the gecko browser embedded in wpf application , Although other contents/element except google map components of the same page are getting displayed in the geocko embedded wpf control(WindowsFormsHost). But when we open the same page in Firefox browser ,it is working fine. It seems like the issue might be related to how Geckofx handles certain JavaScript or rendering features required by Google Maps. Is there any configure or setting that is require to be set in geckofx to get the google map displayed ? or is there anything which is not supported by geckofx ?

I cannot log into websites that use CloudFlare as their CDN. ChatGPT gave me a laundry list of things to check, and after exhausting that list, I decided that the great developers at Mozilla might be able to steer me in the right direction. Below is what ChatGPT suggested:

I asked:

> When trying to log into any resource that uses the CloudFlare CDN I get the following response: > > Icon for givewp.comgivewp.com > > Verify you are human by completing the action below. > givewp.com needs to review the security of your connection before proceeding. > Ray ID: 90067ba77ed70ff1 > Performance & security by Cloudflare > > After checking if I am human or not, the login proc fails with no error message and then just presents the captcha again. > > This only occurs when I attempt to login to resources that use the CloudFlare CDN. > > Is this a known issue with CloudFlare. If it is, is there a known solution to the issue?

ChatGPT replied:

> Experiencing a recurring CAPTCHA verification loop when attempting to access websites utilizing Cloudflare's security services is a known issue that can arise due to various factors. To address this problem, consider the following steps: > > Disable Browser Extensions: Certain browser extensions, particularly those related to privacy, security, or ad-blocking, may interfere with Cloudflare's verification process. Temporarily disable these extensions to determine if they are the cause. > > For Firefox: > Click on the three horizontal lines in the top-right corner. > Select "Add-ons and themes". > Disable the relevant extensions. > > Clear Browser Cache and Cookies: Accumulated cache and cookies can sometimes lead to verification issues.

If the problem persists, it may be indicative of a more complex issue requiring further investigation.

I can't log in to certain sites even though they've been on my favourites list for years, i.e. bank account and grocery shopping. I can log in to them using Edge , so what's gone wrong with Firefox. Is the latest updates to blame ???

My own webpage displays incorrectly when I load it with Firefox, unless I am visiting with a private window.

The page: https://www.coudert.name/publications.html The webfont is Satoshi, and Firefox does load it, but variants do not affect it (bold or italic, for example). All other browsers render it correctly. Firefox on my macOS laptop renders it correctly only in a private window, but not in my normal browsing session. There, it loads the font correctly, but does not apply bold or italics. Compare the difference between the two screenshots.

I have no idea where this can come from. How to investigate? I have checked font-related settings and not found anything of note.

For some time now I have not been able to access any website secured with Captcha verification. My browser doesn't recognize that I'm a human and keeps going back to square one. Importantly: this problem does not occur in other browsers. However, I would prefer to stay with Mozilla, so it will be nice if something can be done with it. I didn't change any settings, I didn't change hardware, I didn't reinstall Mozilla, so that's not the problem. I've looked through my security settings and don't see anything that would help in this case. Especially since these are websites that I had previously accessed and logged in without any problems.

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

suddenly my work account at https://outlook.live.com is a completely white screen.

access to other instances of this account (Onedrive, filesharing etc) are fine. Email account works on phone, so no problem with log-in

I have re-started the browser
