Quoting Alex ARNAUD <alexarn...@hypra.fr>:
What is your version of Debian? What installed add-ons do you have?
Debian version is "testing". Installed plugins (out of my head): * xul-ext-scrapbook * xul-ext-ublock-origin Also from Debian testing.
I don't have the issue you describe with Firefox ESR on Debian 8 "Jessie".
IIRC, I already had this problem on Jessie. I even thought, I filed a bug once, but I couldn't find it anymore.
Firefox developers think also to user of Windows and Mac and you could install add-ons outside of the Debian repository so the check shouldn't be an issue if it works properly.
Maybe the check can be skipped, if only distro-plugins are present. No idea, whether it is easy to find out. What does the check do anyway? Does it try to connect upstream? If so, this would be a privacy breach and must not happen at all or only after explicite opt-in. Cheers
