"It's a memory HOG because of Adobe Flash!!!"
There's a lot of them.
Freezes up too much because of the integration of Flash. It won't release RAM when a task is done. When it becomes non responsive the only way to clear that away is to force it to crash via Microsoft's Process Explorer. I like version 12.0 because it would use too much of my computers memory. This version and 13.0 just hog up my RAM and won't release it whatsoever.
Mozilla, you took 20 steps backwards with your latest versions. I shouldn't have to force it to crash just to make the browser responsive so that I can complete time sensitive online tasks. GIVE ME BACK a more stable version of Firefox!
