Firefox hangs with every youtube clip Rated 5 out of 5 stars

FF 19.0.2 and 1-Click downloader 2.0.3
Used to be ok, but now it hangs Firefox.
To exit, FF has to be killed.
Disabling 1-Click cures the problem.
thanks for a solution... this Add-on is very handy...

This review is for a previous version of the add-on (2.0.3). 

A fix on the way!

A new version should be released within a day or two fixing this issue.
I apologize for this serious bug!
