Reactions to Mozilla’s Announcement about Upcoming Firefox Add-On Changes

Monday, August 24th, 2015

This story is still unfolding; so far, nobody is willing to say exactly which Add-Ons will be broken by the change and which will continue to function.

As a Firefox user you have probably read already that Mozilla plans to introduce major changes to the add-on system of the browser. The official blog post on the Mozilla blog revealed WebExtensions, Electrolysis, Add-on Signing and the deprecation of XUL, XPCOM and the permissive add-on model in particular, and a rough timeline as well. To sum it up: Mozilla plans to focus on WebExtensions in the future which offer better compatibility with the extension engines of browsers such as Chrome and Opera.


Fixing Firefox’s “Couldn’t Load XPCOM” Error Message on Start

When I tried to start the Firefox web browser today I received two error messages instead of the web browser. It would not start because of this, which left me puzzled for some time. The first error read “The program can’t start because pgort100.DLL is missing from your computer. Try reinstalling the program to fix this problem”. The only option was to hit on ok, which caused the second error prompt to appear on the screen.
