Very good add-on. It is Indispensable for anyone who uses Alpha and Beta versions of Firefox. Remembering that this supplement NO is to identify and correct errors, but they are reported to compatibility issues of other supplements that may eventually not function properly, so that in future versions of the browser, these supplements can be compatible.
Summarize: I recommend to users of beta and alpha
Note: Excuse my english, I'm brazilian.

Very useful. Before the tester had to edit every single .xpi file to increase the validity.
