Nice addon, been using it for a while but with the latest version it's missing sometimes on the context menu. This is especially true with the about:support page where I use the search to easily check for updates with installed extensions that takes me to the Firefox addon page. For now I've gone back to 1.28.1, which has been working flawlessly.
Update:1.32a1 seems good. I'll update this again if there's any problems.
I think this bug may have finally been tracked down, with the help of a user @ the github support site. If you're game, backup your current CS config and install the signed pre-release from here: https://github.com/ssborbis/ContextSearch-web-ext/releases/tag/v1.32a1
