There are a lot of Firefox features that don’t get much press, or are quickly forgotten about.  For example, did you know that you could switch to using Gmail or Yahoo! Mail as your default mail client (to handle those mailto links)?
To chance your settings, go to Tools, Options and then click on the Applications tab.  From there, type “mail” into the text box to go to the default mail handler settings.  From the drop down box, you should get [...]

To get to the Applications menu, you’ll want to go to Tools in the menu toolbar, then Options, then click on the Applications tab.

From here you can change just about any way that Firefox relates to any other file, application or task out there.  Here are a few things I did to speed up my browser usage.
ARCHIVES: For archives (like .zip, .rar, ect) I set the action to “Save File”, that way I can skip Firefox asking me if [...]

Foxmarks, one of my favorite Firefox add-on suggestions for bookmark syncing and backup, is changing names today.  Foxmarks is becoming Xmarks.  (Waits for the “X marks the spot jokes)  The new Xmarks service looks to be more geared towards sharing links, ala Stumble Upon and Digg. 
Why make the move?  Well, one would guess that sharing links might be a more profitable business model, more so than bookmark syncing alone.  Via the Xmarks blog, here are some FAQs for [...]

Today I saw my first Firefox 3 extension that bring back “classic” features of Firefox 2. It was only a matter of time before some of these started to pop up and I have a feeling that many more may be on their way.
The oldbar addon replaces Firefox 3’s new address bar with the one that you are used to now in Firefox 2. Here is the new Firefox 3 address bar (or otherwise known as the location [...]

Tired of having Google as the default search engine in Firefox? Maybe it is another search engine’s turn to be on top?! If you feel the urge to dethrone Google as the default search engine for your Firefox search box – this is how you can get it done:
In your address bar, type in: “about:config”
Inside of the filter search box, type in:
browser.search.defaultenginename
Double click that entry (or right click and choose “Modify”) and then type in the name of [...]

Gina is at it again with one of those “Better” Firefox extensions. This time around she tackles Google Calendar. As a big user of the other extensions she has released (plus I use Google Calendar too) I couldn’t pass up on the chance to try this one out.
The Better GCal extension for Firefox wraps some of the best Greasemonkey scripts into one easy to install extension. Editing the options of the extension allows you to also turn [...]

Firefox 2 handles closing tabs a little differently than the old 1.5 version of Firefox does. With Firefox 2 you are given a close “x” on each tab – instead of having it all the way over at the right hand side of the browser.
