Rather than hunting down the X to close your current tab, what if all you had to do was wish upon a star, and then right click anywhere on the tab you wish to shut down?  I will let you know how to get that done, without the need of the “wishing upon a star” part.

When you load up a dozen or more tabs all at once, Firefox can slow down to a crawl.  Now, you can either choose to stop overwhelming Firefox with too many tabs or you can grab this helpful add-on for Firefox that will only load up the tab you need at the time, with multiple tabs still available. 
Just put it on your Bar Tab.

I have one more Firefox 3.6 about:config tip up my sleeve.  By toggling one setting, you can go from having a drop down list of tabs to a thumb-nailed view of each tab that is open. 
Here is how you too can enable this secret Firefox 3.6 feature.

New to Firefox 3.6, when you are on a page, and you want to open a link in a new tab – rather than opening the link in the far right of the tab bar, Firefox will now open the link right next to the tab you are in.  Now, while this might be convenient for some, it is a feature I don’t really need.  So here is how you can disable the new “Insert Related Tab After Current” tweak [...]

With Firefox 3.6’s release, we can all do a quick about:config tweak that will enable the prettier tab switching.  By default, when you hit the keyboard keys Ctrl + Tab you just rotate through your tabs.  By making some quick adjustments though, you can pull up the new tab switcher that you see in the picture above.

Oh undo function, what would I do without you? 
Well, I would probably be forced to do it again – but that is beside the point.  I love being able to reopen a closed tab or window in Firefox.  It has saved my rear end many times.  This is just one of those Firefox tips you really should memorize.

Rather than reloading each tab, one by one, wouldn’t you like to reload all your Firefox tabs at once?  Okay, I realize this might not be a need for everybody, which makes it a perfect add-on for the browser. 
Reload All allows you reload all the tabs in the window at one go.   Need to reload most, but not every single tab?  It can handle that too.  It features a selection tool in case you want to reload a [...]

In an effort to simplify the Firefox interface, did you know you can make a few changes in the about:config page to move the close tab buttons around?  I’ll show you how to move it to the far right of the browser, in just six easy steps.
Before the tweak (notice the close tab button is on the tab itself)

After the tweak (notice the close tab button has been moved to the far right)

Now what is the secret?  You [...]

One of the most celebrated new features of Firefox 3.7 is the feature that will bring the progress bar out of the status bar and onto your current tab.  Did you know though that there is an add-on for Firefox that will let you add this functionality now? 
The Tab Progress Bar add-on for Firefox is the add-on you need.  Having the process bar on top of the tab really makes more sense, as far as functionality goes because [...]

One of the cool Google Chrome browser features is the ability to pin tabs in the browser by default.
Pinned tabs are shifted to the left side of the tab bar where their tab will be changed to just show the favicon for the web site in question. Thanks to the Pin Tab add-on for Firefox, you can bring that functionality to your favorite browser.
Another neat feature of this Firefox add-on is when you type something in the address bar, [...]
