I would also recommend Total Validator: The all-in-one validator.
It checks your code to see if it's compliant with the doc type you use.

I would also add these plugins:

Google Toolbar - Google Toolbar for Firefox
All-in-One Sidebar - https://addons.mozilla.org/en-US/firefox/addon/1027

I like SeoQuake plugins, thanks for sharing here.
Just remember, most firefox plugins here is not compatible with new version firefox, firefox 3

Quite like Rank Checker from seobook.com, though still trying it out. Slight problem with FF3 having compatibility problems with some of the good ones but they are usually updated quickly.

 

[pow-wow]

Linkdiagnosis.com - It check Back link with all the data such as :
* Google Pagerank of every backlink
* Anchor text of every backlink
* if links are no-follow
* most popular anchor texts
* charts with breakdown of pagerank and link types

coll man,

good post. seoquake rocks

I would be careful with overusing some of these plugins though, since too many requests to Google for PR, links etc will flag your IP up as a possible bot and they may block your searches with a Turing test.

Did u mentioned FireBug ? Also some FireBug add-ons: FireCookie, YSlow

 

[SticKer]

I use SEO Quake, Google Toolbar, Stumbleupon and some other plugins. And link diagnosis plugin a new one I added last week

Seoquake is really good for use but it slow down FF speed too much IMO.

DON.
