normally occurs when using firefox and select another new tab. then try to go to say website I want to view. Firefox will then freeze and state firefox is not responding. also receive the un responsive script error and have tried to allow it to finish but to no avail. Whilst firefox was not responding I went to check the task manager to see how much memory firefox was using and nearly fell off my chair! Although firefox was not responding the memory private working set was above 512k and climbing all the time as i watched it. it got to 1312k before I just closed it down. This seems to be an issue everytime firefox hangs. The memory it starts to eat up just climbs up and up and up. Never ever had a problem with firefox before until the recent releases and these freezes and hangs are occuring every single day numerous times and I am getting really cheesed off. I dont want to but I may have to go back internet explorer as at least that seems to be a lot more stable than mozilla firefox at the moment. Dare I say it...think it is becoming too bloated and too much messing about with something that worked fine. Please help!!!
