Hello,
Thanks for your answer.
I could not find the standard Firefox 38.2, so I’ve tested our addon with Firefox 38.0.6, and it works, plus it works too with the latest version of standard Firefox, version 40.0.3. Plus it has always work with the standard versions of Firefox, whatever version number they are.
As a customer reported that our addon was not working with Firefox ESR 38.2, I’ve installed Firefox ESR 38.2 and that’s correct, our addon does not work, it does not interact with the browser whereas it is activated. So I was wondering if Firefox ESR 38.2 was using an about:config a bit different from the standard version of Firefox, or if something else is different between the 2 versions.
Our addon is not signed, but from what I’ve read, in ESR 38.2, it should not prevent our addon to work. I’ve started the process to sign it, but I don’t think it will solve.
Thanks for your help.
Best regards.
Michel
