Has dozens of useful features, is almost like a standalone program on its own. Sometimes it feels like too much or should better be simplified a bit. Another problem is Google directs me to spam prevention captcha thing pretty often.

My favorite ever. I don`t even run my Firefox without that.

does NOT work anymore on google, im using firefox 20, but it didn´t work since ver 18, i unistal it and reinstalit over 20 times, i downgrade and upgrade firefox about 3 more times, i uninstall all other complements to see if there is a conflict, and nothing, but it works like charm on bing, i just did everything possible to make it work and nothing, i´ve been using this great addon since about 2 years ago and very happy until now, don´t know what is going on, i hope this guys solve it soon.
thanks,
P.S.
firefox ver: 18+ to ver 20
seoquake ver:2.8.8

A must have toolbar for everyone who wishes to indulge in web development and marketing, apart from a few hassles and over filled with features, you will not have any problem with this plugin.
One issue that I personally faced was when I clicked the seoquake icon, and re enabled it, the toolbar used to show up over the url address bar and not below it.
