Here is a little more about the Firefox extension from the developers:

termBlaster adds the ability to perform searches from your right-click (or context) menu using one of 110+ websites that range from search engines to encyclopedias to translators. Website lists are in XML format and can be modified in Places.

One would think that speed could come into play when trying to navigate through the search menus but you can do so quickly with little or no effort at all. All you do is highlight and right click the word you want to search and then select the search engine you want to use. They have shopping searches, review searches, torrent searches, map searches, too many to name.

FEBE (Firefox Environment Backup Extension)

Well my number one tip would be to use one extension that will make the job of backing up or syncing Firefox between two machines a lot easier. FEBE (Firefox Environment Backup Extension) allows you to quickly and easily backup your Firefox extensions and settings. It will actually rebuild your extensions individually into installable .xpi files. That makes synchronizing your office and home browsers a cake walk.

One more cool thing about FEBE is that it can preform on demand or scheduled backups for daily, weekly, or monthly unattended runs.

Google Browser Sync

Now if your using two computers on a day to day basis and you want to keep things in sync, a side effect of something like Google Browser Sync extension is that it keeps everything saved onto the other computer.

As long as you get your sync order straight – you could save your settings on your laptop Firefox install, then go back and reinstall Firefox on your desktop – put in the Google Browser Sync extension and everything should get moved back over as it was (as far as settings, bookmarks and cookies go). You’ll still need to reinstall your extensions however.

Backup by Hand (aka the hard way)

Last but not least, you could backup your Firefox by hand. What you want to do is make a copy of your Firefox profile folder. Depending on your operating system it might be in different locations.

Might want to check this page at MozillaZine for more information about where the profile folder is for your computer.

Here is a little more information from the extension developer:

It uses relatively little resources, and works by accessing an IP address database contained within the extension rather than relying on top-level-domain roots like “.com” or “.uk”. Clicking on the icon brings up further information from Wikipedia or Geotool, which is an online Geolocation tool. Geotool attempts to get more information from the Website’s IP address, such as ISP and city and shows the location on a Google Map.
