Firefox is actually decent for retrieving taged links, you just type * in the address field and it will only show you results from your bookmarks. It has become my second brain. I have written more about my use of the built-in bookmark manager in earlier comments if you are interested. My only real gripe with Firefox is that the mobile client lacks the option to add tags. So frustrating!
it is crap and you know it. it barely search the title. not url. not description or tags. which they add and remove from the add bookmark dialog every blue moon. btw i don't know which weird version your using because the current one doesn't have tags even in the desktop. maybe you didn't notice last random change
I'm have been using the latest version of FF for about 14 years, first 10 years on Arch Linux, and the last 4 years on Fedora (the Flatpak version).
