seems this upgrade just came out, and now firefox is running like shit.

1. every so often it's slow to load.
2. it frequently hangs up for a moment, and sometimes crashes altogether, forcing me to kill the process.
3. sometimes the cursors stop working in input boxes.

this started happening to me on both my home PC and work PC -- immediately after the upgrade to 1.5.0.4 -- so i know it's the browser.

so, anyone else experiencing this?
