after 20 seconds of waiting, I get this message:

A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.

Script: chrome://browser/content/preferences/advanced.js:259

I click on "continue" then I and wait for a few more seconds till i'm at the "advanced" section.

what's wrong with my firefox 3.6.16?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).

  • Don't make any changes on the Safe mode start window.

See:

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I ran firefox in safe mode and i still get the same problem of slowdown. could spybot and spywareblaster's immunization and protection blocklist have something to do with it?
