Firefox add-on armageddon arrives: How to see if you are going to be hit
Firefox Quantum is set to speed up Mozilla’s browser, but there is a price to be paid.
Firefox 57 is set to bring the biggest shake-up that Mozilla’s browser ecosystem has seen in quite some time, and the simple reason is that a huge number of browser extensions and add-ons are set to stop working.
Appearing on November 14, Firefox Quantum brings together a number of long-running programs to speed up the web browser — including using its C++ alternative language Rustand multi-process functionality — but it comes at the cost of Firefox’s best feature, its extensibility.
This is far from a surprise, with the switch from XUL to WebExtensions first signalled in mid-2015, but it is a hard break with the past.
Many popular extensions have already been ported to the new framework, but due to extra restrictions imposed by WebExtensions, some existing add-ons are simply unable to do what they once did.
For those still using Firefox 56 and earlier who would like to know what they are going to lose when they upgrade to 57, you are able to see what will disappear thanks to the Add-on Compatibility Reporter.
