In Firefox it used to be you needed to like create your own little mini-addon or something like that, and these days they have "smart bookmarks", but it's such a weird name and doesn't really work the same.
At any rate, I have 100 different little shortcuts defined like for example "tren" which takes the given text, puts it into a translator, and auto-detects language and translates to English. Ditto "sven", "ensv", "trsv", then I have "wiki", "wikise" (Wikipedia Sweden), "wikt", "aw" (ArchWiki), etc., etc.
I use these hundreds of times a day, and when I tried converting to Firefox (before I eventually landed on Brave) I couldn't find a simple way of moving these from my Google Chrome profile to Firefox and have it work like I expect it to. Perhaps that's possible now?
