Ever since evolving past the 70's version, "Print to PDF" from Firefox has had sporadic problems. I have now three times "upgraded" to various 80's series releases and though sometimes Print to PDF works, it more often fails. Once again i have "downgraded" to a 70's release, and i do not experience flaws. I have posted at least twice of the issue, yet no one is able, or has done anything, about it. Fine. But to keep getting that annoying "New version available" notification is as irritating as malware, especially since "upgrading" will cause the system to malfunction, and the choice to spend time by your programmers to eliminate a safe internal method to disable this is very confusing; why was the decision made to eliminate the option to turn that annoyance off, creating an annoyance when the only time one would turn upgrades off would be when there was a malfunction with a release? I did find the external registry fix, which, compared to pre early 60's releases having the setting, was a waste of my time to find, but more importantly, added an outside element of a breach of security. I do not understand the reasoning in the development team's thought process.
