Have you checked with Kaspersky for an updated, Firefox 4 compatible version of that URL Advisor?

Thanks for the reply, edmeister! I just updated my Kaspersky to the most recent version. Still having the same problem. I put in a "trouble" ticket with them and also posted in the user forum. Nothing yet  :( Hopefully something will pop soon, as I don't feel safe operating without it.

Here's the "skinny" on going back to Firefox 3.6.x.

Thanks for the links, edmeister! Much appreciated!

I'm going to give Kaspersky a day or so to respond, and if no success with them, will follow the instructions from the links you provided.

I am a little concerned, however, that the add-on issue may not be fixed by reverting back to previous versions, as indicated in common issues with updating/reverting. Sorry, forgot to copy that text, but you'll see it if you follow the link.

Thanks again! Your help is greatly appreciated!

You're welcome.
