@Diego Casorran (Developer),

No, I'm running nightly with E10 disabled. No BluHell icon on toolbar, and doesn't seem to be running in the background as far as I see.

Are you sure it should be running correctly on current nightlies with E10 disabled ? It doesn't work here. Uninstalling/Reinstalling didn't help either.

This review is for a previous version of the add-on (2.4.0.1-signed).  This user has 2 previous reviews of this add-on.

Thanks for the follow up, that clarified the problem since until now the only incompatibility i was aware of was e10s - just checked it myself and seems the CustomizableUI module got changed as well :-(

Well, and answering your question: No, Bluhell isn't marked as compatible with Nightly builds, and never was, but it usually worked - a shame the current situation, i'm sorry.

EDIT: Version 2.5 should now work on Nightly 37.0a1 with or without e10s enabled.
