I'd like to figure out a way to have customized Google searches to choose from in the Firefox search bar in the top right corner. By customized I just mean the possibility to add specific pre-defined keywords which would then be appended automatically to the performed Google search.
For example, if I am looking for movie subtitles, I'd just like to be able to select my custom made "Google Subtitles Search" that would just magically add a "subtitle" keyword to the search.
