Usually i have 50 tabs open. I have upgraded Firefox to version 3.6.15 and Adobe Flash to latest version 10.2.152.32 | 10.2 r152. After that started seeing constant hard drive activity and plugin-container was taking over 300Mb. I have disabled all plugins and Adobe Flash. The end result was positive - plugin-container now takes 1Mb, there is not hard drive activity and when i click on already opened tabs, they open faster. I still have not tried reactivating all plugins, but have a feeling the problem is in Adobe Flash.
Does anybody have same problem?
Anybody knows where i can download previous Adobe Flash versions? I will have to downgrade because i cannot live without Adobe Flash.
