For me i am careful not to trust to many addons. Several addons have "turned against the user". I trust gorhill and ublock origin. I only install verified by Firefox. Disable when not needed anymore.
Besides that i think Multu account containers cookieautodelete Bitwarden Treestyle tab
I also use vimium although it pains me or had access to everything, and it's not verified. So it only runs in nonessential windows.
I consider myself long time noob ;)
Fedora for me because it's rock solid, has cutting edge software, excellent documentation.
I,ve been updating the same installation more than 15 times i think.
Against: selinux is often overlooked when following guides written for Debian / ubuntu. So sometimes you pull out your hair.
On the other hand. Podman is supposedly the new favorite kid on the block. Fedora is on the front here
