I've been using Firefox since it debuted. But I never really got into the Themes, Extensions or Add-ons for Firefox until Version 3 (current version). I've used the delicious add-on since version 2, but that was the only one, really. Oh, and the time I used the Tinseltown theme well past the holiday season.
But recently, I've discovered several kinda cool extensions that I thought I'd share:
Iterasi - you can capture (they call it "notarize") web pages and save them in a personal archive which you can then subsequently share with friends. And you can schedule notarizations to occur at regularly scheduled intervals which is pretty amazing. Iterasi also lets you add tags and organize the pages. It's pretty neat - your own web archive. Via Lifehacker.
SEO for Firefox - this is an amazing extension from SEOBook - it lets you see SEM data like page rank, backlinks, cache date and a bunch of other data points right inside your Google or Yahoo search results. It's a toggle so you can turn it on and off, plus there are several options for customization. Plus, it also gives you direct links to keyword research, trends, traffic estimator and a few other things right below the main search box. So HANDY!!!
In the two examples below you can see the data you can get about each page in the results (I used my name as the search) and then the additional links for the keyword search itself (using "laptop bag" in the second example.).
RankChecker - Another great tool from SEOBook - this one lets you track a number of keywords for a particular domain. It will show you the keyword rank and associated URL for Google, Yahoo and Microsoft Live. You can then download these results into a CSV file; you can also save the query and run it at subsequent times. Great tool if you're watching your site or a client's for particular keywords!
FireBug - If you ever need to do some CSS troubleshooting, FireBug is your secret weapon. I love this add-on. You can right-click and inspect any element; it gives you a window pane with all the CSS code. Plus, you can edit the code in the pane and it will render the change. Very powerful.
UnWrap Text - my friend Ed put me onto this one. You can highlight a multi-line URL and it will open it in a new tab (in case the URL isn't hyperlinked). But my fav use is that you can highlight a multi-line address and it will open it in Google maps. Sweet!!
I've also got Feedly installed. I really like it; it's a magazine-esque take on all your feeds, but I haven't fully figured out how to integrate it into my current feed reading workflow. I haven't made it my start page yet - maybe that's the problem. Plus, it is integrated with Google Reader which I don't actually use as my reader - so, it does require the changing of habits. Also, I forget who turned me onto this - perhaps Joe Thornley? If not, h/t to the forgotten smartie pants :). (Note - there should be pretty pictures in the four boxes in that screenshot - am not sure why they didn't load.)
Any Firefox extensions or themes that you use? I'm back to using the default theme (Christmas in August - not good), and I see it as a bit of a time sink to try to find another one. But if you have one you adore, let me know!
UPDATE: Mozilla just announced their Best Firefox 3 extensions. Timely!
