Komunitné fórum Firefox

I tried to login to k9data.org. This is a re-write of a product I've used for years. So far as I can tell, others are now using the new version. When I login the screen clears and shows entry into a url called ff.newtabsearch.net. It claims to be a new addon for Firefox. However, following the instruction, I get in a loop and there is no indication that any addon was installed.

While browsing youtube,i no longer find cast to tv icon in Firefox browser.Can you help me please,as after stroke my eye-sight is diminished.I was able to do it before,as i switched over Linux Mint 22 wilma,i am unable to find this cast icon.Thanks.

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.

I updated Firefox to version 138 yesterday(29rd April). I use latest stable version of Linux Ubuntu. Sites itself will work, but top of browser wont. Can click open new tab from +-button, but can't close it.

Browser stops reacting to mouse clicks when browsing (after hours of browsing) and I have to use right-click to navigate on sites.... until I restart browser. I tried to close tab and refresh tab when these problems occurred. Also, this occurs on all sites.

I think this is clearly browser problem(because clicked areas are on browser, not inside tabs), not problem in sites itself, because problem manifested itself after hours of browsing, not immediately.

Edit: I'm not well-versed enough to write Bugzilla-report. Also in 138.0.1-1 version, where I updated 3rd May 2025.

Edit 2: I've added picture of area that stops working. Edit 3: On another picture, can't close "Archaeology" tab, no matter what. Edit 4: Clarified things up.

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 forgotten the purpose of the green outline around the page's border. What does it do and how to turn on, after turning it off. Thanks in advance. Let me know if this is an extension or some other feature. Thanks, JJE

When attempting to access the Twitch website in normal browsing mode, the page does not load properly. Instead of the site rendering, I only see a black screen with an infinite loading spinner.

This issue does not occur in private browsing mode (incognito), Twitch loads normally there.

I found that performing a browser reset temporarily resolves the issue, but after some time the problem returns. Continuously resetting the browser is not a practical solution.

Additional details:

   Browser version: 141

   Steps to reproduce:

       Open Firefox in normal mode

       Navigate to https://twitch.tv

       Observe black screen with loading spinner

   Expected result: Twitch should load normally

   Actual result: Page remains blank with a loading spinner

   Private browsing mode works correctly

Please advise on a permanent fix or steps to diagnose this issue.

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

Javascript is not working in my firefox. Even going into settings to enable java script doesn't work, because it says java script is enabled. But the webpages tell me that they need javascript enabled in order to work.

I get a different UI when I open NotebookLM from google. My pixel tablet uses Chrome and it loads with the standard 3 panels but in Firefox I only get one screen. Everything else works in the program.

For the past week now, every time I go to this link https://marketplace.secondlife.com/ , it is in another language. Usually Spanish or Portuguese and now and then French. I'm always having to translate. Even though my settings says English and i have no other options.

No idea if this is the right topic or not but I've been dealing with this frustrating issue where with some websites it just loads a blank white screen. I've tried every fix I could that I've seen on forums like this as well as on Reddit and nothing I've tried has fixed it. From launching in Safe Mode or changing things in about:config. Before finishing this post I tried launching in safe mode, so my add-ons and plugins are disabled and it still persists with websites loading in these blank white screens. I never had this issue at first and I'm sure it started to happen after an automatic update a while back.

I need this issue sorted out so I can look and compare items from shops but most of the time a website that works and I look at it elsewhere I'm dealing with this issue. No issue looking at stuff on the internet on my phone, though I do use safari instead on my phone.

We tried 2 different computers, but two different users. Type in the user name and the password and it looks like it will start up, but then returns to the login paged.

Amazon pages don't load on Firefox 146.0.1 (64 bit). I'm using a Windows 11 Desktop PC. I cleared the cache but still have the problem. Please advise. I've used Firefox as my primary browser for decades but if this issue is not resolved, I may be forced to switch to a new primary browser. Anthony
