Some days ago we created a customized google search engine for ROR, now you can use this search engine with Mozilla Firefox. What you have to do is: Download rails_search.xml, save it in your searchplugins directory under Mozilla FireFox installation path (usually it is  C:\Program Files\Mozilla Firefox\searchplugins) and you are done. Restart FireFox and Rails search engine will appear in the search engine list at top right corner.

*To download the file, right click on the link above and save link as rails_search.xml
