Windows Vista Aero interface competing with Ubuntu Linux and Beryl.

One of my favorite business model suggestions for entrepreneurs is, find an old UNIX command that hasn’t yet been implemented on the web, and fix that. talk and finger became ICQ, LISTSERV became Yahoo! Groups, ls became (the original) Yahoo!, find and grep became Google, rn became Bloglines, pine became Gmail, mount is becoming S3, and bash is becoming Yahoo! Pipes. I didn’t get until tonight that Twitter is wall for the web. I love that.(source: http://radar.oreilly.com/)

Configuring the extensions

Install your chosen extensions and restart Firefox.
Right after the restart you’ll need to configure some of them…
- Forcastfox will ask you for your zip code
- you will be ask to disable TabMix Session Manager and use the built-in session restore.
- Foxmarks will start its setup wizard, you should create a username if you don’t have one.

Fasterfox

Right click on the Fasterfox icon, select Options, a new window will open, make sure you have Turbo Charged selected.

If you have a good internet connection you could also enable enhanced prefeching - it will utilize idle bandwidth to silently download and cache links in the background so they may be ready for immediate display by the time you click them.

CustomizeGoogle

Lets customize CustomizeGoogle extension - click tools > Customize Google Options.
There you can set specific options to each Google service.
If you use Docs or Calendar I suggest you check the Secure (switch to https)
If you are a GMail user you can remove the invite box, the quick contact box etc. (I really hate the invite box)
You can also choose to remove the ads from most services and anonymize the Google cookie (Privacy section).

DownThemAll

DownThemAll is a really good download manager, Lifehacker has a really nice article about it.

FEBE

Tools > FEBE > FEBE Options
You can tell it to backup more than your extensions (your bookmarks, preferences, whatever).
In the FEBE Options window, click the directory icon and select where you want to save the backups.
Once you are done with the options go to Tools > FEBE > Perform Backup and you are done!
