Great extension, been using it for years in multiple browsers. For what I need, it works flawlessly. One question though: is it possible to remove or "uncheck" the 'Use Alternate' option from the context menu? I only use two search engines and added 'Search All' just in case.
P.S. If you're planning to use the 'Use Alternate' option to offer a way to search for local images, then I retract my question, as I want that too, when you'll find a working solution :D
RESPONSE TO THE DEVELOPER:
Thank you. Don't worry about the timeline - I understand the difficulty of adapting your sofware to these constant changes in browsers, given the fact that I am also in a process of developping an extension for Chrome...;)
