Remove empty space above tabs in Firefox 4 beta 6 title bar

These instructions for Firefox 4 beta 5/6.

1. Find your userChrome folder inside your Profile folder: to find your profile folder, see: http://kb.mozillazine.org/Profile_folder
   
   
2. Find the "chrome" folder and open it.
   
   
3. Edit userChrome.css
   
   
4. Add this snippet to that file:
   

   @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
   
   /* Note: assumes app button is visible (menu bar disabled) */
   
   /* Move tabs up to titlebar */
   #main-window[sizemode="maximized"] #navigator-toolbox[tabsontop="true"] #TabsToolbar {
       padding-left: 112px !important;
       padding-right: 112px !important;
   }
   #main-window[sizemode="normal"] #navigator-toolbox[tabsontop="true"] #TabsToolbar {
       padding-left: 112px !important;
       padding-right: 109px !important;
   }
   
   /* Move the menubar above the tabs so it moves the tab bar down when activated */
   #main-window[sizemode="maximized"] #navigator-toolbox[tabsontop="true"] #toolbar-menubar {
       margin: -19px 0px 3px 112px !important;
   }
   #main-window[sizemode="normal"] #navigator-toolbox[tabsontop="true"] #toolbar-menubar {
       margin: -24px 0px 3px 112px !important;
   }
   
   /* Curved corners when tabs-on-top and normal window */
   #main-window[sizemode="normal"] #navigator-toolbox[tabsontop="true"] #nav-bar {
       -moz-border-radius-topleft: 5px !important;
       -moz-border-radius-topright: 5px !important;
   }

5. Restart Firefox.
   

Disabling Etags from affecting your YSlow score

YSlow is a great tool to quickly determine what optimizations can make your site quicker. However, Yahoo determined to include checking for ETags; if the server in question has ETags enabled, YSlow scores will be negatively affected. This should really not always be true, as ETags aren't always "bad"; if your site runs from a single server, having ETags enabled helps.

Looking for an explanation for this, I came across a comment from David C-L inside the Yahoo Developer's Blog:

• Type about:config in the Firefox address bar.
  
• look for the setting named extensions.firebug.yslow.pointsEtags and set it to 0. If the setting doesn't exist, you can create it by right-clicking and choosing "Add".
  

Now Firebug will not ignore the ETags setting on servers to determine the YSlow score.

Drupal in the Cloud presentation from Drupalcon 2008

This presentation is not only interesting for Drupal developers; it's a great starting point for learning about what cloud computing is, the difference between platform-as-service and infrastructure-as-service, a list of companies offering these services, what some dangers and benefits are... and more. They detail what it takes to put Drupal into the Amazon EC2 service, and show a video of what a Firefox-based cloud administration tool looks like.

Recommended.

Firefox 3 RC 1 released

It's been out for a few days, but I wanted to try it out first.

I'm happy! It's solid, lightning fast, and worked with some extensions I really need like Firebug and Live HTTP Headers.

Go ahead and Get It Now!

Firebug for Firefox 3.0b+

Firefox 3 being so fast, it's painful to have to go back to Firefox 2 just for the great extensions like FireBug. However, I found out that the beta 1.1 of Firebug works great!

1. Run Firefox 3
2. Go to: http://getfirebug.com/releases/
3. Click the link under Firebug 1.1 Betas
4. Confirm the XPI install in Firefox.
5. Restart!
6. Ta da!
