Which do you think are best? I know its a nice amount of them but, I really dont want to have them all and slow down firefox...
SEO quake is the best I used till now. But it also causes slow down. There are several options in it you can set what features you need and control the loading speed.
A simple light one for links is NoDofollow... pretty handy. (another +1 for seoquake for a nice overall one)
I use: SEOBook toolbar Seo4FireFox NoDoFollow WARNING: Don't surf around with these ON. Only turn them on when you need the data, they pull alot of data otherwise. (well, seobook toolbar and seo4firefox that is) Reasons I use these: SEOBook toolbar is useful to turn on when I want the data for a page that I'm currently viewing. It gives me all I want, backlinks, whois info, etc. Seo4FireFox is great to use when you look up a word/phrase in google and you want the PR/backlinks for the SERP results. It's customizable to only show what info you want.. I highly recommend you do so, otherwise there is just a ton of (what I consider) useless stuff. Doing this allows you to see what kind of competition you are facing for a search term on the first/second page. NoDoFollow is pretty self explanatory, it highlights links that are NOFOLLOW in RED. (and dofollows blueish-purplish) Like I said, they are off most of the time, and just one click away when I want to turn them on to get the data. Hope that helps!
Seo Quake is bomb SEO 4 firefox seem pretty good, but it looks like seo quake does some of what it does. web developer since i do alot of css editing Firebug since its just so dope with altering website css and such on the fly
SEOquake and SearchStatus are good extensions for firefox but the most useful for me is the RoboForm. I've been using it ever since i've been doing SEO. I just do backlinks manually and so some other things
