So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

Firefox is unable to open large PNG. Tried opening the same PNG in other browsers (IE/Chrome) without any issues. The PNG is being served via webserver.

The initial error message was unable to open the image. I reset and restarted firefox in safe mode and now I see broken image.

I can upload an example image, if needed.

I decided to clear all the cookies along with the browser history. After that I can't get access to my yahoo email. After trying to sing-in I get "a problem loading page" with the following message:

"The page isn't redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies. "

I' ve tried with IE (bliahhhh!) and there isn't any problem. Could you please provide me some advice? Thank you in advance for your interest.

I primarily use Firefox as my browser on my newer iMac with mountain lion. I had accidentally deleted some family photos from my desktop and used a recovery tool program to scrub my hard drive for recently deleted images. The program worked very good as I was able to recover my deleted family pictures but I had to go through hundreds of images to find them. In those hundreds of images I went through, I found screenshots of my Firefox activity from banking sessions, to amazon shopping, to google searches. I was stunned. They were only screenshots of Firefox browsing sessions. Hundreds. All taken without my knowledge. I clear my data often on Firefox. Cookies, cache, history, etc. I clear everything. Does anyone know why this is happening and how to stop it? It's definitely a security issue, a lot of the screenshots even showed "sign on" screenshots of banking sessions and amazon user names, email log-ins, etc. I don't know where the screenshots are stored, like I said I used a deleted image recovery program and it doesn't tell you, it just finds files. I scoured my computer looking for jpgs, pngs, etc and couldn't find anything on my own.

Firefox doesn't recognize FLASH after update, no matter what. Also says to update plugins but there are none to update listed?

I have downloaded & re-downloaded FLASH, but after I updated my Firefox to 22.0 it no longer recognizes FLASH is installed on my computer. It also keep telling me "Some plugins required by this page have been blocked for your protection." When I check the plugins, the 3 listed are up to date, and the other 3 are marked "research" - which doesn't allow you to update them. I cannot discern that any of those are what is being blocked. When I click on Details, it brings me to a list of "Modules bloqués" and it's all listed in French...which would be great if spoke French or lived in France, but alas California is in the USA. My Java is updated, enabled & not blocked in any way. My Shockwave Flash is disabled & it will not give me the option to Enable it; I also cannot find a way to reinstall it or find a plugin to help me. !@#$%! So frustrating that this new "update" is useless. I hate 22.0.

What do I do now?

When I open a private browsing window on FF26, a Google.com cookie is placed. This cookie is not removed when finishing private browsing. The cookie is placed before any activities have taken place in either the normal FF window, or the private browsing window. No startpages are set, the windows open with a blank tab.

Where does the cookie come from and how do I permanently get rid of it?

I backed up my firefox bookmars, and the file that came out of it is no specific file type. Even in the properties, it just says "File type: File".

So now i'm trying to restore my bookmarks, but I can't open that file. If i try opening the file itself with firefox or any other browser for that matter, I get long pages of text. It does contain my bookmarks, but it's really hard to read. What can i do to fix this?

Using these methods, it does work. However, after each restart, another parent.lock file is created and the profile folder becomes read-only again. How do I fix this permanently? Move to Chrome?
