Browsing this website article I can see that there are embedded Youtube videos in the article but they are not loading, instead I only see blank spaces. I've turned off all extensions, turned off tracking protection, cleared cache and cookies for both the website and Youtube.com, and tried viewing the website in troubleshoot mode.

Duck duck search via Firefox has become painfully slow, although if Google search is used the speed is OK. I have cleared caches, cookies etc without any improvement. Firefox 148.0.2, Windows10. Is this a recognised current problem?

I have switched OS, from Windows 10 to Linux Mint, and wanted to copy the Firefox profile to the new OS. I tried using this guide: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

I copied the xxxxxxxx.default-release folder, then switched OS to Linux Mint. After copying the files from the backup folder into the new folder, Firefox launches, but is completely blank. See the attached image. None of the buttons work, nor does the address bar or new folders. I also tried logging in to my Firefox account before copying the files, but that didn't work either.

Default Firefox works fine.

Hello Folks, I just importeda a new certificate. Then I wanted to save all my certificates for backup. Selecting "Backup all...", I neter a secure password and click ok just to get the following error message: Failed to create the PKCS #12 backup file for unknown reasons the only button is "OK"

How can I start finding out what is going on and is there any means to save my certificates?

When I open a new tab, I have it set to the home page. When I go there, it adds the most visited sites, yes? ok. but...now when I go there, it has a bunch of sites past my pinned ones. When I dismiss one, all of them disappear except my pinned. A few minutes later, I open a new tab, and theres a bunch of new sites again, but I can only dismiss these one at a time, and they again disappear for some minutes, or a couple/few tab openings. Bug or feature? how do I fix it?

Password Manager will not save a URL larger than the first few words (base URL). But the site necessary to login contains more directions after the "xxx.com", and Password Manager truncates everything after the ".com" so it will not return to the proper site to login.

I really REALLY don't like tab buttons

How can I make sure they NEVER come back ?

I have tried the violentmonkey script, doesn't work, I have it right now and look, there are TWO tab buttons on my tab !

Firefox was updated. I was Hacked. Now I cannot log into my email Provider. Firefox is my default browser. How do I access my email provider via firefox browser now?
