I'm not the person you asked, but here's my reasons.

I'm on Linux and there no longer is a supported version of Flash by Adobe. (Apparently there is some NPAPI to Pepper bridge though, to get Chrome's Flash working in other browsers.)

I already uninstalled before that, because I wanted to force HTML5 for sites that dynamically switch between Flash and HTML5 and because I wanted to nudge more sites to support HTML5 by boosting the stats of people who don't have Flash installed.

I'm using Firefox on Ubuntu with Flash (flashplugin-installer) and it's still receiving updates. It's an older version, but it has been working fine with every Flash site I've visited so far.

Yes, looks like I was misinformed there. While there are no more feature updates, security issues will continue to be released for about another year. (If I'm piecing the information here together correctly https://www.adobe.com/devnet/flashplatform/whitepapers/roadm... https://helpx.adobe.com/flash-player/release-note/release-no...)

Not from my experience. There's quite a few sites that require a newer flash player, so it's either Google's PPAPI Flash or Windows.

I think everyone got most of my reasons covered below, but here they are: no need to manage updates, smaller security surface, battery life, fan noise. I typically browse with Firefox Nightly, and without flash installed globally I get HTML5 or whatever a site wants to offer me if I don't advertise flash compatibility. If I hit some must-have flash I have a key combo that opens the current tab in Chrome.

Historically, it's tended to have had far more zero day exploits than the web browsers themselves. removing Flash removes a huge attack surface, and 95% of the time you don't need it.

I don't have flash installed (usually using Safari and Firefox) and have to jump over to Chrome to use a site maybe once or twice a week, which is more than acceptable given the insecurity of Flash.

I really don't like flash. It's full of security holes and its primary uses annoy the living hell out of me. So I only use a browser that has it when it's on my terms.

Then you enter the toxic hellstew of Flash Player updates.

don't need to install. Now its default in browser

Not in Firefox, and the GP said they're only keeping Chrome around for Flash.
