filter to block side bar ads

[sbk]

I'm using Grypen, and have never seen a side slider. I have seen a large squarish popover, mostly in 2011, and on sites I've never visited before or again. To fix that, I toggled css off, or toggled js off then reloaded the tab.
(Note to anyone just coming to this prxbx tread by chance web search: If the page looks sketchy, I turn off javascript, then close the tab. Don't click the "Close" in the popover.)
Quickjava extension has toggle buttons for css, js, and other firefox options. Use version 1.7.5. The later 1.8 has a bug where the hidden buttons can still be mistakenly clicked. I put the update url in proxo UrlKill file to prevent firefox updating to 1.8.
More recently, I also began using Noscript extension.
