Extra features: Add one or more of the following pairs of lines to your userChrome.css file to customize your Office theme:

/* change the tab close button to a different and larger close button */ @import url("chrome://global/skin/alt-close-button.css");
/* always use green back/forward buttons */
@import url("chrome://global/skin/alt-nav-buttons.css");

This theme based on Microsoft Office can be picked up on the Firefox Add-ons web site.

Here are some of the extension types it can recognize and handle:

• Documents (*.doc, *.rtf, *.odt, *.sxw)
• Spreadsheets (*.xls, *.csv, *.ods, *.sxc)
• Presentations (*.ppt, *.pps, *.odp, *.sxi)
• Images (*.jpg, *.gif, *.png)

How do you use it?  Well whenever you face a document with the “Open With” option, it will also give you the option to open it Online.  From there you can choose one of the various Web 2.0 tools to view and edit the document in question.

One last really nice feature is that Open IT Online gives you the ability to also see the file size of the document you are about to view.  This is handy in determining if you want to open the file, or not.

You can pick up the Open IT Online extension from the Firefox Add-ons site or learn more about it at OpenItOnline.com.

Want to go back to the Office?

Now I don’t know too many people who say, “I’m such a big fan of Office, I wished all my apps looked like this!” but love it or hate it, the Office look makes for a pretty nice Firefox theme. If your looking for that traditional Microsoft look – but with a little class and style the Office theme for Firefox might be the download you have been looking for.

Stick it up your aero, Vista!

Our next Firefox theme inspired by the Microsoft machine looks like it fell out of Windows Vista. If your a big fan of the way the new Internet Explorer 7 looks then the Vista-areo theme might be up your alley. Sleek blue style with that Microsoft glow.

Crappy, yet classic Microsoft style…

Now this is the style that you know and love. No wait, does anybody really love the classic and familiar look of IE6? No – it couldn’t be.. could it? Well if you do fall in that camp then the Looks Familiar theme for Firefox is a download you might want to do in private. Close the blinds though and make sure nobody sees you using it.

Since I eliminated my wall calendar this year and started using Google Calendar to write down all my important dates, I have been catching myself from time to time looking up at the blank spot where the wall calendar used to be. While browsing through extensions I think I may have found one to help me get my date fix. the Date Picker/Calendar extension gives you a little date and time notification the bottom of the Firefox window.

This extension will add the current date/time to a small pane in your status bar. You can then click the date and a calendar will pop up, where you can scroll through months or years looking for the date you’re interested in. When you click a date in the calendar, it will be displayed in a handy text box which then allows you to copy it out for whatever purpose.
