I work with a number of different clients when it comes to web optimization for search, or SEO, and a number of times my clients are amazed at how much I know when looking at their website at a glance. Over the phone, within seconds, I can tell them a lot about their website like the level of traffic they are getting to their website from a quick glance at their Alexa rating, or a quick view of how many, if any, pages they have indexed in Google’s search engine and more.
Firefox Wallpaper (Source)
As a Mozilla Firefox user (the browser that you should be using) I have adapted to the many changes in the browser over the years and have become used to about 12 or 13 plugins/addons that I can’t live without as a webmaster.
FireFox Add Ons I Can’t Do Without
The main Firefox Add Ons that I have to have are listed below along with a reason why I find them so useful.
Firebug
Firebug is a wonderful piece of software mainly useful to web developers.
If you aren’t a web developer then its probably not going to be of much use to you. Learn More
Flagfox
Although somewhat insignificant, Flagfox comes in handy if you want to know in which country a website’s host server is located. 
This tool helps with avoiding scams in some cases, and can help with credibility.
NoDoFollow
After you install the NoDoFollow FireFox Add-On, you can quickly scan a webpage for nofollow and follow links.
Another great tool for webmasters.
SEO Doctor
A useful tool with its own SEO metrics. Can come in handy when determining if a page needs SEO work. 
WebRank SEO Toolbar
I can’t live without this plug in.
A Toolbar that gives the Google Pagerank, Alexa, Compete and Quantcast Rank of the website being viewed. Also get the Pages Indexed and Backlinks from Google and Bing. Find its share count at Twitter, Facebook, Google Plus, StumbleUpon and Delicious using the SocioMeter. Learn More
How To Get The Add Ons
If you are a Firefox user, and you should be, click on “tools” then you will see the “add ons” option. You can also CTRL+SHIFT+A if your version of the browser isn’t showing you the “tools” menu option. Once in the Add-Ons section, simply search for the Add Ons you seek.
