Firefox Community Forum

Hi there! Ever since I believe two days ago, playing videos in the Firefox browser have been giving me issues. Videos often end up looking scrambled/glitchy. It starts off mostly in green but sometimes turns multicolored, and the tab the video is in starts lagging or freezing. At first I thought it was a YouTube issue, but it's happening on other websites as well, even for animated gifs. I tested some videos in Edge, and so far I haven't had any glitchiness there yet.

I currently have Windows 11, and Firefox is up-to-date. I've attached screenshots from three different websites. Happy to provide other info if needed!

Firefox 134.0.2

Hi!

I was shocked when I recently visited a website of a company that offers IDEs. I've downloaded one of the IDEs a couple of weeks ago and now that I've came back to the website looking for plugins, the website still "knew" which version of the IDE I had downloaded because it gave me warnings about plugins not compatible with my IDE version. Now: My privacy settings in Firefox are "strict", the option "Delete cookies and site data when Firefox is closed" is checked and I've closed Firefox several times in the meantime. Still, the website has information about my identity.

I would have expected that with these settings something like what I've described wouldn't happen. I must say, I'm quite disappointed. Is there anything else that I can do within Firefox to enhance my privacy?

Plugins that I've installed: CanvasBlocker Cookie Autodelete Decentraleyes Forget Me Not NoScript

I have changed my primary password but when I try and sync I am told to reconnect my account by signing in. My password is then rejected multiple times, but the same password works on my Iphone. Any thoughts please?

Ok I have been having an issue where someone is trying to access my computer via remote acess and it happen only when im about to click on play on youtube.

evidence provide this should concern both mozilla and eset.

Hello to you up there ! I have Windows 11 - 23H2 up to date ! since 21/1/2025 each time I start Firefox (up to date 134.02 - 64 bits) I get a warning from Malwarebytes Browser Guard that blocks a outgoing request coming from Firefox via port 443 to the IP 82.221.136.1 ( = welcometothemachine.co …. what is that ?? analytics ? AI  ??) .... I am asking myself why is Firefox trying to go to that IP because I never did ask for something like that and how to delete the whole request every time now .... (CCleaner does nothing when used) ... bizarre bizarre behaviour yes ! Who can answer me. Can you please also answer me on geomar@scarlet.be because I would not like to miss the answer ? Thanks.

I have a number in a circle showing up on the Firefox icon on my taskbar. For a while it was a number 1, then that went away. Now I have a number 5 in a circle on the icon.

I deleted my browser and reinstalled to try and help with some lag issues. Now every time I turn the computer on, this message displays-before I have clicked a link to open FF. What is this trying to tell me exactly?

I'm experiencing an issue where the fonts in the Firefox application interface are broken or appear distorted. However, the fonts on websites are displayed correctly.

I have already tried resetting browser settings, reinstalling Firefox, and clearing cache, but the issue persists. It seems to be related specifically to the application’s UI fonts and not website rendering.

Steps taken so far: - Manually cleared profile and cache (in ~/Library folders) - Reinstalled latest firefox.

I just updated Firefox only because I got an email saying my version would no longer be supported. EVERY TIME I update something goes wrong. This time the SEARCH field on my address bar disappeared--I can't do searches. HOW DO I FIX THIS? ALways next to the address was a place for inputting searches--WHY would you disappear this? Also WHY is the pointer so large I can't read text underneath when I roll over icons?

On several web pages, when i try to log into the accounts i have on those websites or account creations, when i try to click "Continue" or "Log in" or what ever may be the case to actually finish the process, the button will not actuate. I have tried on Microsoft edge and it works with no notable issue.(It just is slow because its Edge. lol) I dont have an adblock going of or anything of the sort that appears to be blocking the operation. Please heeeeeeelp.

I inadvertently created a duplicate Other Bookmarks folder at the level of the Bookmarks Toolbar and I'm not able to remove it. In fact, I tried deleting all of the bookmarks under this duplicate to see if that would allow me to delete it, however, that removed all of my bookmarks, including from the original Firefox Other Bookmarks folder and I had to restore them from backup.original Firefox Other Bookmarks folder

Please let me know what I can do to eliminate the duplicated folder without affecting the entries in my original Firefox Other Bookmarks folder.

Thank you,

When I open a web page with a video in it, the video generally starts to look like the attached screenshot. It usually happens within 30 seconds, and then it will occasionally clear up for 10 seconds, but otherwise, it's just a shifting swirl of green.

Does not happen in other browsers.

This will happen and cause the page to stall, not load, which is especially bad on a page with a download link or if it's a search engine. The highlighted part of the attached image is an example of which part of the URL flashes incredibly fast - appearing and disappearing.

I just recently had an instance of the url bar typing the same word and deleting it over and over again at the end of the address. I was watching the word "drawers" appear as if I was typing it myself, letter by letter.

Refreshing doesn't help and will refresh the previous page because the faulty link will carry over to the next page if it's on a search engine for example.

I've noticed that when video media begins to play, it often suddenly slows down the entire browser's processing ability and cuts to strange visual glitches limited to just the video window, usually green and pink pixelated glitches. This doesn't happen on YouTube, nor does it happen when I use other browsers like Edge. I'm on Windows 11, using the latest Firefox version, with Strict privacy settings and a reliable and simple adblock. Had the same setup on a previous Windows 10 laptop and did not have these issues. It's getting frustrating and is impacting my experience with this browser across multiple websites. I refuse to switch back to sketchy, predatory browsers like Chrome and Edge, so I hope this can be fixed, either on my end or on Mozilla's. Thanks! (Attached a screenshot of the visual glitches.)

Hello!

I am reaching out regarding an issue I am having lately. Recently a great number of sites has been showing me an error regarding an embedded site and blocking me completely from it's content.

I've read on many forums and searched the brower console and it seems like firefox is having an issue with X-Frame-Options being set to "sameorigin". It gives me a lot of trouble and is blocking me out of a lot of media.

I love security measures Mozilla has implemented over the years but I do not feel comfortable when software I use won't let me toggle less important safety features On/Off or at least whitelist sites I know are safe.

Speaking bluntly, it's ridiculous that I have to try 10 different websites with the content I want to watch, just to find one that has a built-in player, instead of an embedded one. It also seems to be spotty with what it blocks and what it doesn't block as some sites with an embedded player work with no issues.

I couldn't find any way to turn it off that won't possibly affect other security measures, or won't require me to go into brower console every time I want to access media.

Please instruct me how to fix this issue and consider making changes regarding it.

Thank you in advance :)
