Ad-Block plus makes some websites such as Twitter unusable

more options

Hi i have been having problems getting a lot of functionality working in many websites in Firefox where there is no problem in IE. A particularly problematic is site is Twitter where most of the functionality doesn't work (All dropdowns, number of characters remaining disappears, can't tweet etc). On investigation this is being caused by the prominently advertised Firefox add-on "Ad-Block Plus" which i have enabled. (When i disable it, everything works). When i check the list of blocked items on the Twitter page there are none. Therefore this add-on is causing severe problems. I appreciate Ad-Block plus is designed to block items, but when it is not blocking anything on a page it shouldn't block functionality. I also appreciate Mozilla do not make or support Ad-Block plus, but my point is that you are encouraging users to install an add-on that ruins website functionality. There are a couple of add-ons that have an exclamation mark and warnings they are unsafe, i would suggest Ad-Block plus now has some warnings on it? thanks Richard

I have today discovered that Ad-Block is NOT responsible for ruining the functionality of some websites such as Twitter. This may be of use to the people who have flagged the same problem. My discovery is that when blocking sites using Ad-Block, i somehow managed to block ajax.googleapis.com This was what was causing the problems. As soon as i delete ajax.googleapis.com from the blocked list, the websites become fully functional with Ad-Block enabled.
