TL;DR: Firefox has already disabled everything other than Flash, Flash is currently discouraged, and Flash will be killed off in 2020.

At some point in 2018 I decided to disable the Flash plugin on my system. I figured I would end up activating it maybe once every three months. I was surprised to discover that a surprising amount of video content is still displayed via flash players. Let's hope that 2019 is the last year of that crap.

Wow. I removed Flash from my system about 4 years ago, keeping one browser installed with Flash on it just in case. I've never had to open that browser.

I'm the same. I use Firefox on Linux and installed Chrome since it comes with a flash player. The only times I've had to open Chrome, I've regretted it (flash content wasn't worth it).

Just stick to non-sucking sites and eventually other sites will go away or improve.

The only times I've had to use flash in the past two years have been for school. Most textbook publishers still have almost all of their online content only available in flash. The worst I've seen was a site with a login screen written in flash, I don't even want to know how that happened or how easy it would be to exploit.

>When Adobe stops shipping security updates for Flash at the end of 2020, Firefox will refuse to load the plugin.

So much for giving the user freedom!
