Makes firefox to hang (lags, delays, etc.) Rated 1 out of 5 stars

Well trust me. I spent almost 2 hours trying to find out why my web page lags (I'm a web developer). And then when I disabled this addon everything was working smooth again. Download it at your own risk. Checked with operating system Windows 7 64bit.

This review is for a previous version of the add-on (1.4). 

Fixed the bug mentioned by you. Thanks for reporting this bug. We are now doing all the requests asynchronous. So it will not cause any lag or delay. Please try the addon again and give me your feedback. Thanks
