Symptoms: Clicking between tabs is very slow. When I do switch, some or most of the content on the page is gone. I can scroll over links, but I can't see them. Ctrl/Alt/Del doesn't work; the only way to fix it is to restart.
When I do the shutdown, a message box pops up:
A script on this page may be busy, or it may have stopped responding. You can stop now, or you can continue to see if the script will complete.
script: chrome://bprivacy/content/bprivacy.js:970
The number is different each time.
My OS is MS XP Professional 32-bit SP3, and my browser is Firefox. I don't have Google Chrome loaded or even on my disk, nor have I ever used it.
Help, please.
