I went here: https://www.google.com/cse/ and created a custom search engine to get better results when searching Mint/Ubuntu sites. The result works very well, although it is only presented as a piece of html that is supposed to be embedded into a website. Well I don't want to do that, I want to use it as a search engine in Firefox, but I can't find the way to do this. At the moment the html code is just saved as a file which I click to launch the code in Firefox, but this is very inconvenient, I am sure there must be a way to get it recognised as a search engine, and then I could give it a keyword when I wanted to use it. Anyone know how I could achieve this?
BTW. the firefox addon 'Add to Search Bar' is no help, it just tells me: "new EngineURL: template uses invalid scheme!"
The best I have come up with so far is a keyboard shortcut to launch the file that launches the search window - hardly 'integration' though.
