Sometimes I need to open XML files on my PC or in a network folder. If I open the file in the first tab in Firefox, it displays a neat and formatted rendering that makes it easier to read. However, if I open yet another tab, it displays a sequential text file that's difficult to read. How can I apply the style of the first tab to all open tabs? I've attached explanatory images (I hope). The second image shows how I'd like the XML file to always be displayed, regardless of the tab's position. Firefox 149.0.2 on windows 11

I purchased VPN to carry on seeing Bitchute in UK....used it on my Ipad and works fine. Followed the process on my PC to download etc but it doesn't seem to work. Also can you switch it on and off seemed easy on the Ipad, but makes no sense on my PC (Windows 10) Thanks

Best Buy Tech support took control of my computer today to get my printer to scan to the computer. After that was done, I went to my FIREFOX hompage only to see it completely changed from the way it was and I am now trying to get it back.

Suddenly to use Passwords list on Firefox Windows is demanding I sign into Windows, where previously I used the special "master" password I use only on Firefox. I want to disable this intrusion.

I liked my search box functioning like it did before the last update...can you please revert it back to the way it was please or give us the option to change it back. Why mess with perfection???...thank you. (149.0 64bit currently)

Every time I want to search an item or word, you now take me out of the search bar and throw me on to the address bar, which I really have to struggle to read. This has been going on now for quite some time. my question is WHEN ARE YOU GOING TO FIX THIS PROBLEM?? I DON'T WANT TO HAVE TO GO TO config TO DO IT MYSELF. FIX IT ON YOUR END NOT MINE! And now as I scroll down, I see you've made some guesses. Then information gives details about the internal workings of your browser, IT'S NOT MY BROWSER, IT'S YOURS. FIX IT

Every time I attempt to change my search engine from DuckDuckGo I am unsuccessful. The browser simply reverts back to DuckDuckGo. I am running Windows 11 and have installed each and every update that has come along.

I uninstalled Firefox and then downloaded the latest version. When I tried to log in, I found that clicking the login button didn't respond, which led to the inability to log in! I logged in successfully using the troubleshooting mode. However, when I used a vpn to access some websites like github (i am a student in china), the login status dropped and I needed to log in again. But at this time, clicking the login button didn't respond. I hope this problem can be fixed. Otherwise, if I can't log in and use the vpn, I will have to try using other browsers. But I really like Fiefox! Thanks!

What do I do if Firefox wont let me log into my account on a website because the "certificate has been revoked"? I think it has to do with the "enhanced tracking protection" setting.

This is what the advanced message is:

Be careful. Something doesn’t look right.
