Hello Paul

Firefox advanced customization and configuration options, it seems to me, that's what i specified.

https://www.reddit.com/r/FirefoxCSS

Another possibility. Below, only with this userChrome.css file.

:root { --tab-border-radius: 0px !important; }

I greatly appreciate the replies but thats all too advanced for me honestly. i think i will try finding an older update and install it then turn off updates.

If that doesnt work i think i will just buy a mac because my friend showed me Safari has options for it

Just wanted to update that this worked!

I found this page and installed version 144.0.2 and the rounded UI everywhere is gone!!!

the second part was going into settings > general > Firefox Updates section > Uncheck "When Firefox is not running" > Select "Check for updates but let you choose to install them" and then just dont update again!

Problem solved! I will now reinstall firefox on my systems and work computer. We are back up and running. Thanks guys!

If you wish to try

:root { --toolbarbutton-border-radius: 4px !important; }

Copy/paste the code into Notepad Save Type: All files userChrome.css

Create a chrome folder Move userChrome.css to your chrome folder

Go to your profile folder https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_how-do-i-find-my-profile

Move your chrome folder to your profile folder

Go to configuration editor https://support.mozilla.org/en-US/kb/about-config-editor-firefox Enter a search term toolkit.legacyUserProfileCustomizations.stylesheets Double-click on the preference, to set its value to true

And restart Firefox, and see.
