What Will Firefox 57 Break?
Add-ons can be important accessibility tools. I’m strobe-sensitive, and use dozens of add-ons and user styles to protect myself, to be able to use the web. Firefox 57 cuts support for Xul add-ons, in favor of Web Extension add-ons.
I’m using Firefox 52 ESR because I want to be able to use the web, but I’ve checked addons.mozilla.org to see what breaks and what will survive in Firefox 57:
* The new version of addons.mozilla.org is much easier for me to navigate than the old version.
* "block animation" mostly yields adblockers, and a couple video blockers; that's not enough.
* Configuration Mania hasn't been updated for Firefox 57. Not sure if it can be.
* uBlock Origin may have been updated. YesScript hasn't been updated, though YesScript 2 might work.
* QuickJava and an alternative called Prefbar can't be updated.
* Kill Button has disappeared. SuperStop seems to remain, but it can't do as much.
* Flashstopper and alternatives such as Flashstop haven't been updated. Not sure if they can be.
* Refresh Blocker hasn't been updated. Some sites flash due to frequent refreshes.
* No Small Text hasn't been updated.
* Activate Reader View hasn't been updated.
* GreaseMonkey and Stylish have been updated, but not all styles work. If I knew more about programming, I'd probably convert all styles so I had working duplicates, and update one of the extensions to see which styles break.
* Translate This! hasn't been updated.
* Tumblr Savior may have been updated.
