Hiya, Joeychgo...
I'll try to start writing them down, so you can see.
Some of the times, going through various pages, when trying to scroll down the page, I get no response...then the error pops up. Scrolling flat won't work, until the script is stopped. Each time only hit 'stop' the script, then okay.
Others, seem to be ad related, as they try to load.
To make things worst (though not all the time), still get the 'firefox update' re-direct'. That only happens when I open the home page first load. Read up on that one...scam...to gather info? Spyware, I guess.
If it helps, on Windows XP.
