Mentioning since you say you don’t like ugly, I use Pano (on Gnome 49/Fedora 43) and have no issues with Kate (current version from Flathub) and it looks pretty (imo) as it does little thumbnails for everything. Although I’ve been meaning to try Copyous as it has that + at pointer paste.

Or in the present case, just never go to LinkedIn.

One thing that I wonder is if I can convert my old firefox -P profiles into this new kind of profiles, and have them all be synced by firefox with a single account instead of recreating them on all my devices. On the filesystem they seem to be the same, just not in the same place.

If you are speaking of the needle position on the dial thingy, I believe it’s just the default until you vote, not meant to indicate anything (though it’s misleading). You have to vote to see actual results.
