I use both Firefox and IE (for different purposes) but all of a sudden both of them stopped opening javascript links on webpages and pdf files. I don't know if the two problems are related or not.

This is what happens when I click on a javascript link. The new page doesn't open and...:
Firefox - JavaScript console has the error message, "new_window is not defined" or "GetBookURL is not defined" or any number of other error messages depending on the site.
IE - It says, "error on page", in the bottom left corner of the browser

When I click on a pdf file link on a webpage I get a blank page. I can still download pdf files. I have Adobe Reader 7.0 installed on my computer.

I've already tried reinstalling the browsers and Sun Java. I've tried connecting through both my wireless gateway router and my dial-up connection. I've tried allowing and not allowing pop-ups. Turned firewalls off and on. Nothing works so far.

Further suggestions would be greatly appreciated. Although these are very simple functions, they turn out to be pretty vital to much of the work I do. Who knew?

Thanks.
