      Greetings all,


      This error from Firefox  has been a thorn in our side for quite some time.  We do SSL inspection which I assume is the source of the issue.   I've added a lot of sites to SSL bypass, figuring this is a certificate pinning issue and that something Firefox is doing in its updates is crying foul here, but I'm still apaprently missing something as this error persists in this environment.


      ...in the process of pasting the following, I found an errant space  in the versioncheck-bg  pattern  (i.e.  mozilla.org  !=  mozilla. org ) that I believe may be the reason this was still not fixed.... While I'm hopeful that finding this errant space in my url pattern will solve my problem, I'm still curious to share notes with others on this one.

      2https://versioncheck-bg.addons.mozilla.org/*  Yeah, url.host faster, but let's keep all rules for mozilla in one place until we get this figured out
