Easily open multiple tabs when Firefox starts
Firefox lets you specify more than one site as your home page; each page will open in its own tab when you start Firefox. To specify multiple pages, you separate each address with a pipe character (|) when you set the home page.
Example: http://www.google.com|http://www.0092ff.com
Note: This feature may lead to unexpected results when you try to set your home page to a site that contains a pipe character in the address. To fix this problem, you will have to replace the pipes with their escape code (%7C).

Make Adsense Notifier work with Firefox 3.5.*
For those of you that use, or used to use Adsense Notifier, you’ll find out that if you switch to Firefox 3.5, Adsense Notifier will no longer work. Well, I’ve got good news for you! If you follow the steps below, you can have it back.
Step #1 – Create a new folder on your desktop.
Step #2 – Download the Adsense.xpi file to that new folder by right-clicking on that link and choosing “Save Link As…”.
Step #3 – Rename the downloaded Adsense.xpi file to “Adsense.zip” and unzip it as usual. If you can’t see the extension within Windows, click here.
Step #4 – Open the install.rdf file with notepad.
Step #5 – On line #33 replace this:
33 | <em:maxVersion>3.0b5</em:maxVersion> |
with this:
33 | <em:maxVersion>3.6.*</em:maxVersion> |
Step #6 – Save the file.
Step #7 – Zip all the contents back up the same way it was and name it “Adsense36.zip”.
Step #8 – Change the extension back to “xpi”.
Step #9 – Open the Adsense36.xpi directly within Firefox by going to File > Open File.
Step #10 – Click on Install and then you should up and running.
Note: The fix worked for me, however, I am not providing a guarantee that this information will work for you. It should though. Good luck!
Firefox 4.0 Theme Mockups
Those Mozilla people must not even sleep anymore! It was less than a month ago when the they released Firefox 3.5 and now they’re working on Firefox 4.0 already. Below are the screenshots from Mozilla’s wiki page:
Personally, I prefer to have the tabs on the bottom, but that’s just me. We’ll just have to wait to see what Mozilla decides to do. If they gave you a vote, which would you choose?

Has anyone tried it yet? I think I may wait until it’s officially released.
Firefox Add-on: Firebug 1.3.0
If you use Firefox (which you should be) and you’re a web designer, then you need to install this free tool. I just recently started using Firebug when my layouts became more advanced and included more css.
“Firebug integrates with Firefox to put a wealth of web development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.”
After installation is complete, you should see a little bug icon at the bottom of the Firefox window (see image below). With the desired page in your browser, click on that bug icon to bring up the Firebug workspace. You can also press F12 to get the workspace up. To open it up in a new window press Ctrl + F12.

Once the workspace is up, you can navigate your HTML/CSS in the left section and then see the style properties in the right section. Something that I just learned is that you can click on “Layout” tab on the right and it will show you a picture of the various divisions/blocks. That comes in handy when making pixel-perfect layouts.
While you navigate the code in the left window, you can hover on different tags and it will highlight the corresponding item on the page. If you click that tag, it will show you the properties on the right. You can also click “Inspect” on the top left hand side and that will let you hover over an object on the page and it will highlight the corresponding code. As you can see from the image below, I’ve hovered my mouse over the “

For me this feature has proved to be a tremendous help when dealing with many nested divisions on a page. I’m sure that there are many features that I haven’t discovered yet, but so far this tool gets an A+ in my book.
