Apparently Firefox 57 will break most extensions.

These include a number of safety and accessibility tools, so either users will need replacement tools, or we'll need to stick with 56.

I'm photosensitive. I get nasty migraines, and other symptoms, but luckily not seizures. I need 25 animation-blocking tools, including 10 "legacy" animation-blocking extensions, and 12 animation-blocking user-styles. It won't be easy to track down replacement tools. addons.mozilla.org is itself full of animation, with the top bar growing as it loads, and with items flashing on mouseover.

There is a WebExtension version of uBlock Origin available. Most (all?) user styles should be possible with userContent.css (websitea) and userChrome.css (Firefox user interface) in case there won't be a Stylish replacement.

Otherwise you can consider to switch to the Firefox 52 ESR version that will be supported with security updated until about Q2 2018.

There is a master pref in the current Firefox release to disable a few user interface animations.

What other extensions are you using? There may be replacements possible.

55 has already broken uBlock Origin, which I have to uninstall and reinstall each time I open Firefox. So 52 looks like the best option.

I had to do that every time I used Firefox in 55. Not in 52.

Just follow instructions....You're posting on here for support, aren't you?. Read the reddit thread. uBO's developer gorhill4 posted an official response to this issue. This is the bug that caused that to happen. It's fixed in 56.

I did follow the instructions.

Unistalling and reinstalling uBlock Origin only worked until I closed Firefox 55. had to repeat each time I reopened Firefox 55. Since I don't leave it open all the time, that was an extra pain.

I find Firefox 52 works much better, and it won't break my other accessibility tools either.
