Works as advertised Rated 4 out of 5 stars
Works well for me with, i'm using it with PHPStorm on Fedora 18. Debugging and profiling both work, no problem.
The Add-on preferences form is still buggy, I can't change the IDE key. The workaround is simple enough:
Type "about:config" into the location bar, then search for "extensions.easyxdebug.idekey" and change the value manually (double-click on "value", then enter your IDE key).
