So been moving around a lot with browsers, waterfox, librewolf and very recently degoogle chromium, figured id look at Firefox and holy theres less than half the option in setting then there were afew years back but I gotta say the biggest sin is that adding custom search engine is obfuscated, and the chooses of engines are google, bing, duckduckgo and fucking Amazon! Wtf is that about? But anyway all these search engines are pretty awful including duckduckgo but beyond that the browser scene is a joke, mullvad are about the only company I feel compatible with using now
Edit: instead of saying how easy it is to add custom search engines, I'd like to know why the "add search engine" feature in settings is gone?
I turned the behavior of "try to resolve and if it doesn't work, feed it to a search engine" off, because I don't want my slightly-mistyped URLs to go to a search engine, and I want to have easy access to multiple search engines.
Instead, I just add a keyworded bookmark for each search engine that I want to be able to use. Right-click on search field, choose "Add a keyword for this search…". Firefox lets you set a keyword for the bookmark.
It'll replace "%s" in the bookmarked URL with whatever your search query was. If your keyword is "gn" and you have it set up to search Google News, then "gn brushfires australia" will search for brushfires in Australia.
