I was hoping this would work, since Search Engine Helper is long dead. But nope. This error shows up when trying to add a search engine using dpaste.org: "SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data" What a shame. :( If only Mozilla wasn't incompetent and not busy adding AI features, and added this one f**ng feature properly years ago..

Used to work great, but it seems like both servers are down (somebody spammed them with cp, what?). I will try to find the other way to make a custom search engine now :(

JJ·31 Mar 2026

I just removed the extension because Firefox now also natively allows to add custom search engines via the settings (see extension description). Unfortunately, both available upload services of the extension are currently down, making the extension unusable. However I always loved the extension and used it a lot over the past years so I wanted to leave a positive review as "goodbye".
