I have Windows 2000, DSL access, and just updated to Firefox 7 which seems to run much slower in many ways: any thoughts?
Firefox starts as quickly as before, but switching between tabs or closing tabs often takes forever. Also when I drag to highlight a long page and copy, the scrolling speed is much much slower than before. To highlight a long passage I have to drag just the beginning, hold that with the Shift key and use the arrow keys to highlight the whole passage within any reasonable time. Closing Firefox is usually as quick as before, but once in a while it gets constipated and takes 30+ seconds to close -- though I suspect this might have something to do with some open tabs. (By "close" I'm referring to when it leaves the screen, not later when it is dropped from memory.) I average 3 or 4 open tabs with brief periods of 8 or 9 open tabs.

Please try this: Tools (or Alt + T) > Options > Advanced > General. Under Browsing deselect Use autoscrolling, Use smooth scrolling, Use hardware acceleration... if any are selected.

Thanks, I'll try it.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
