Rated 5 out of 5 stars
I love this extension. Unfortunately, it has ceased to work in FF 10 (both Beta 1 and Beta 2). I first noticed this when trying to create "é" (I ended up with an "e", but no accent); I then tried a number of combinations, and none work.This review is for a previous version of the add-on (2.8.1-signed.1-signed).
The Reviewer has contacted me and I found out this issue was affecting gmail only; I found a fix which will be released in version 2.10.
For contacting me about problems like this, use the Zombie key toolbar button and the bottom menu "go to the Zombie Keys support site..." then you mail me from the bottom of each page. The toolbar button can also help to figure out what the correct shortcut would be - but make sure you have the correct keyboard layout configured!
