1089856 - Flash 15.0.0.189 severely janks the browser

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[Jared Wein [:jaws] (please needinfo? me)]

I updated my local Flash install on Windows 7 to version 15.0.0.189, and ever since Firefox janks severely. So much to the point that I had to uninstall Flash.

STR:
On Windows 7 with latest Firefox Nightly
Install Flash 15.0.0.189
Open a few webpages that use Flash (espn.com, irccloud, youtube)

With e10s enabled or not?

Does this jank manifest itself as a pause when creating a new plugin instance, but after that it's mostly fine? Or do you end up with continuous jank until Flash is gone (or even worse, forever)?

pauly, can you try and reproduce and get a profile if you experience this?

Continuous jank while any pages are open that use Flash, and it persists while the Flash plugin is loaded. I still had issues after killing plugin_container.exe, but I'm not sure if it was Firefox recovering from the deathgrip that Flash had put on it or if it was going to stay in that state (persisted for > 30 seconds before I closed Firefox to uninstall Flash).

Everything's fine to me on any of the pages mentioned in comment 0.

Ok, it's all working fine for me after reinstalling today. I'm not sure what the hiccup was, but it happened for me after multiple installs/uninstalls. I'll reopen if it comes back and try to grab a profile.
