I recently gave a list of the Firefox extensions that I used. I also spoke about Deepest Sender. I just got a new computer and had to reinstall all of my extensions. I am using Firefox 22.214.171.124. One of my extensions did not work so I had to install Nightly Tester Tools to get BBcode to work. All you have to do is install the NTT and restart Firefox and you can install BBCode. It does require you check the NTT checkbox before you hit the install button for BBCode. In the future if you upgrade your Firefox all you have to do is go to the extension window and click on the NTT button and it will make all your extensions work. This was very useful.
I got some new ones as well.
Domain Details – This adds a little menu when you right click on a web page. It has two options. The first is just a plain whois. You have to enter a CAPTCHA for this one. The second gives a report about your site. Stuff like Backlinks, Alexa info, where the server is, type of webserver, pagerank, and info from your registrar. The second does not require a CAPTCHA. They both open up in an unfocused new tab.
