TableTools for Firefox

TableTools is a Firefox extension that lets you sort, filter or copy HTML tables on the Web. For example, if you come across a Web table that isn't sorted alphabetically and doesn't give you the option to sort, you can right click on the table, choose the sort option from the TableTools menu, and it sorts the table in place, automagically, without leaving the Web page or having to cut and paste into a spreadsheet or other software. You can also filter Web tables : TableTools adds dropdown menus to the top of a table, allowing you to filter by terms in any of the columns. You also choose to copy the filtered tables as tab-delimited text or HTML to other programs. TableTools can't handle everything, though. The download site notes it has trouble with more complex tables, such as tables that are nested.

50 Best Firefox Extensions for Power Surfing

If you're a Firefox user, you'll want to check out the 50 Best Firefox Extensions for Power Surfing. The ability to enchance Firefox with various extensions is the reason I use it instead of Internet Explorer as my default browser. My personal favorites from the list:

• Tabbrowser Preferences
• IE View
• FirefoxView
• PDF Download
• DownThemAll!
• TargetAlert
• GreaseMonkey
• BugMeNot
• Bookmark with Del.icio.us
• Web Developer

That's not to say the other extensions on the list aren't valuable, I just haven't tried them or don't have a use for them.

DownThemAll!

One of the handiest Firefox extensions is DownThemAll!, which lets you -- with one click -- download all the documents or images from a Web page. You can also use filters, so you can just download PDFs, or Excel files -- whatever. There are fancier tools to do this sort of thing, such as Wget, or HTTrack, or Curl, or rolling your own Perl script, but DownThemAll! is the simplest and the easiest to use for the most common scenario: When you come across a page with a lot of stuff you want to download quickly without tediously clicking on each and every link.

Send to is a useful Firefox extension that lets you send text selected in the browser to a file. It also adds a date, time stamp and delimiter. New entries are appended to the same file.
