Firefox with Plugins may lead to some problems with telerik controls

I had an issue with the telerik radTabStrip control.
It wouldn't switch the tabs. In some cases you are only able to navigate between the first and the last tab, in some cases you may not be able to change tabs at all.

I was very surprised as telerik is famous for supporting cross browser functionality for all the controls.
I thought the problem may be in my TV but wasn't able to find anything.
A collegue of mine also had some problems using firefox full of plugins with the telerik controls but we never thought the problem may be in the plugins.

In my case the problem was in Interclue add-on used to preload a page for you (when you point a link, the plug in will give you a screenshot of the page that stands behind the link).


So if you ever have problems using telerik controls under FF - please check your plugins first.
