After lot of difficulty, i switch from Firefox to Chrome. I was using some extensions, that made switching to chrome difficult (like TextAloud). I loved FireFox, main reason i switched on Windows as security, with no sandboxing, i had to use Sandboxie with firefox, that caused problem with Flash (protected mode) and keeping flash updated was a problem, some times it fail to update. Switching to Chrome helped me say good bye to Windows. Now using chrome on Ubuntu. Have firefox installed on ubuntu, but scrolling is slow, not sure related to my mouse. I don't like too many process by Chrome, it have security advantage, but it made difficult to use task manager/ps aux.
