Rated 5 out of 5 stars
Great addon, but there's a problem in Firefox Nightly (26.0a1 as of Aug. 20). The Disable Flash icon is crossed out and a tooltip says "Flash could not be found". I changed the plugin name to exactly to how it shows up in the plugin settings, and also tried the 0.9.4 beta, both didn't change anything. It works fine in Aurora (25.0a2) though, so I suspect that some change in Firefox 26.0a1 broke it.This review is for a previous version of the add-on (0.9.3.1-signed).
Caused by a bug in the current nightly, will be fixed with one of the next nightlies. (See your e-mail for more details)
Edit: Fixed in Nightly 2013-08-23. ;-)
