Rated 3 out of 5 stars

Doesn't work with russian search engines (FF23 Portable Russian).
Can't use "Яндекс".

This review is for a previous version of the add-on (1.0.3.1-signed). 

I'm trying to recreate this bug I can't. Which Russian search engine are you using? I tried Yandex, and when I paste Яндекс into the URL bar for a search, it redirects properly. Can you give me the resulting URL from the search?

This is fixed in 1.0.4.
