Iâ€™ve decided to go for it – I removed all extensions from Firefox, and upgraded to the Beta I mentioned yesterday. So far, so good. No crashes yet, and itâ€™s running fast and smooth.
Memory use seems better, but itâ€™s usually a day or two until the problems really show up, so Iâ€™ll reserve judgment. Iâ€™ve been pushing it pretty hard, though, and itâ€™s only occasionally peaking over 100Mb.
This morning, Firefox 1.5 was peaking at over 430Mb. On a machine with 512Mb, thatâ€™s a lot. Even opening task manager to see how much it was using caused the system to hang and page furiously. Opening an Explorer window showing My Computer took minutes.
