Worked great until... Rated 4 out of 5 stars
I really like the porting of this concept, it's worked great since I updated to FF4, but with FF7, the context menu never gets altered when the search engine changes. For example, if I highlight <text> on a webpage then right click, there's a context menu entry "Search Google for <text>" even when I have Yahoo (or any other choice) as my current search engine. It should change to "Search <current selected search engine> for <text>".
I've switched to OmniBar 0.7.10, and the functionality is restored. Let me know if a list of my other add-ons would be of use.
Thanks for using Foobar and the high praise! You're right about the broken behavior - I've noted it and will look into it for the next release.
