Gread Addon but CPU hungry Rated 3 out of 5 stars
This is an amazing add-on is almost ever way. I say almost because I have noticed how CPU hungry it is.
I was tired of having Firefox using 30% of my i7 CPU while sitting in the background so I disabled all my add-ons and decided to turn them on one by one; every time followed by Firefox restart. After doing so for ~40min (I got 24 add-ons installed) I found out that Speed Dial was to blame as it eat up ~13% of CPU power, even when Firefox was sitting on static page. Definitely something that should be improved.
