Since the update to 49.0 and subsequently .1 and .2 whenever I'm on Facebook and login to Clash of kings (Flash Player required and is latest version) the game is completely unplayable. Jerkiness, slowness and basic no playablity. My PC is no slouch as it's a gaming rig but for Flash Player to reach up to 2.2Gb of memory usage is kind of weird. So far I've seen no evidence of issues with other websites but there are not many that I go on that still require Flash Player but I play Clash of kings a lot and unfortunately the latest Firefox updates have "forced" me to use IE yeah IE!! who the hell uses that! Because it has no issues at all playing Clash of Kings and it still uses Flash. Hoping you will resolve this because Firefox is my browser of choice and I refuse to use Google Chrome and will only use IE if in dire need. If you need more info then I'll post it here, but whatever you did in 49.0 broke some stuff. Cheers, Dave
