Now, don’t get me wrong – it does still display the flag as I mentioned above, but there are so many other neat features this add-on delivers that I never knew about until I tried it.  Some of these include:

• Site safety and malware checks
• Finding similar sites and reviews
• Automatic translation to your language
• SEO and web development research
• Diagnostics like pings and traceroutes
• Whois and DNS information
• Page code validation
• Quick URL shortening
• Copying a server’s IP address or other info
• or you can create your own custom actions!

If you looked over this add-on before because you thought you could probably live without knowing where a server is located – please give it another shot.  It delivers much more than you would ever think from an add-on that is based around such a simple idea.

You can pick up FlagFox for Firefox from the Firefox Add-ons website.

This extension for Firefox would come particularly handy when it comes to working on a project, where you need to keep track of which tabs are with which set of sites.  For example, if I was writing something about Firefox, I might flag the Mozilla sites I was getting information from green and the non-Mozilla sites red.  That way I can quickly see the difference between the two.

So if you are in need of another way to organize your open tabs – FlagTab might just do the job.
