I'm taking an online course with Flash video lectures. I noticed that every video gets progressively slower as they progress, and are basically a slide show by the end. I pulled up Task Manager during one and watched the Physical Memory Usage go from 35% to 65% in one 90 minute video. This has got to be why the videos are slowing down. The process hogging all them memory is called "plugin-container.exe *32". This process was about 900MB by the time my lecture was over, and it disappeared as soon as I closed Firefox and all the memory was freed up. It must be the Adobe Flash plugin. My question is, how do I fix this? I did some searching online, and it look like I'm not the only to have this problem. One place suggested trying the 64-bit beta (v11.0.1.98), which I did, but the problem remains. Tried disabling hardware, same. Have any of you guys had this problem?
