Messes up my Fx install Rated 1 out of 5 stars
It does what it says, in that it lets you get the Alexa and Google rank of a site. However, as other users have stated, it takes up significant resources. In addition, it interfered with some built-in Firefox functionality that I had configured. Most notably, it reset the "close window with last tab" option that I had set to false. Regardless of what I did, the window would close with the last tab, and the tab bar would not stay visible.
There are enough alternatives to this plugin out there, and it looks like they need to fix some issues here. This plugin messes with core Fx functionality, which makes it an absolute no for me.
The resource bug has been rectified it in the latest version (1.2.4).
We suggest giving it another chance.
