Do you use a lot of Google services?  The Firefox add-on, GButts, will help you get quick and easy access to any Google service you want, next to your address bar or anywhere else you might need it.
Here are all the Google services you can quickly show or hide via the extension.

You can customize how much space you want to save with the options across the bottom (by making the menu a toolbar or a drop down menu).  You [...]

The Back to Close add-on for Firefox adds a simple ergonomic feature to Firefox I am sure a lot of people will enjoy.  When you are browsing via the browser or via a tab, if there is no history to go “back” to via the back button – it displays a “close” button instead.

This simple change adds functionality back to the toolbar.  The extension also works with mouse gestures and and by configuring the back button on your mouse [...]

Some time ago, I told you about my favorite tutorial for people wanting to know how to build their own Firefox theme.  I am happy to say that the twisted-one himself, TwisterMc has updated his digital class in Firefox design to cover Firefox 3.
There are a few requirements, such as getting your own unique UUID, giving TwisterMc some credit, and coming up with something original – but those are easily done in exchange for the knowledge you will be receiving.

Tired of having the stop button taking up too much room in Firefox?  Well, you could remove it from the interface all together or hide it, until you need it.  The Smart Stop/Reload extension for Firefox will combine your stop and reload buttons into one.
This is to save you toolbar space, plain and simple.  To avoid unintended reloads, the button is disabled for a split second when a page has finished loading.
For those of you who might have the [...]

And the actions [...]

I have never run across a Firefox theme with buttons that were this big till now.

The Kempelton Large theme for Firefox delivers in the big button department for sure. You can still get a little ‘bit smaller icons if you go with the ‘Use Small Icons’ option when using this theme. Use the standard Kempelton theme instead if you want a more typical icon size.
Do you like the big buttons?

Need a quick and almost painless way of getting rid of those pointless “go” and “search” icons in the Firefox 2 interface? While doing a little customization on my own install, I ran across this tutorial via the Firefox Extension Guru’s Blog.
With the new default theme for Firefox 2 there is not a ’simple’ way to remove the ‘Go’ Button from the navigation toolbar. I never used the go button since I simply press enter after I type in [...]

There is nothing wrong with the Go button and there is nothing wrong with those who like it. Hey, if I had a reason to use it – I would. Thankfully though, I have an enter key, which in turn does pretty much the same thing. Banish the Go button from your installation of Firefox 2!
What do you need to do? Well just type “about:config” and scroll down till you see this:
browser.urlbar.hideGoButton
Then change it from false [...]
