gtuhl: startup IT and software development

I finally grabbed the latest beta (beta 4) of Firefox3 and absolutely love it. The downsides are that many extensions are not yet setup to work and there are rendering differences. I fixed a half dozen visual problems today primarily related to button input widths and absolute positioning of iframes.

Overall though that doesn’t matter because the fixes were minor, the important extensions are ready to go, and the new browser is fantastic. My personal list of observations includes:

• It looks fantastic and like a true OSX application.
• The rendering speed is incredible, I no longer have any reason to run Safari given that it no longer has the advantage here.
• The memory issues appear to have been resolved. I generally never shut down my browser and would only kill Firefox in the past because of the rolling memory leak that would eventually consume my machine.
• I love the way that alerts (such as whether to remember credentials for a login form) are now a slick pop-in div that does not interrupt or delay your browsing. They used to fire up in abrasive popups.
• Bookmarks are beefed up in several nice ways, though I use delicious so not massively useful.

Here is the new default look of the toolbar area. I really like it.

So the new browser is great, but it does have some rendering differences and it is still beta so at the moment having both the beta FF3 and the stable FF2 installed is a great idea. Here is what I did to set it up where both are installed and can run at the same time. I am assuming you currently have FF2 and are adding FF3 and also assuming you have never messed with your Firefox profiles before.

• Make sure Firefox isn’t running.
• Rename your existing Firefox application to Firefox2.
• Open a terminal and run /Applications/Firefox2.app/Contents/MacOS/firefox --profilemanager.
• Rename the default profile to Firefox3 (this is preference, feel free to skip or name it whatever you want).
• Create a new profile named Firefox2
• Download the Firefox3 .dmg from here.
• Mount the .dmg and copy it into your Applications folder.
• Rename the new Firefox application you just copied over to Firefox3. Renaming this is mostly so spotlight searches and dock mouseovers can be differentiated.
• Create a file named firefox2.sh in /Applications/Firefox2.app/Contents/MacOS/firefox2.sh with this content.
  

  #!/bin/bash
FFDIR=`dirname "$0"`
cd "${FFDIR}"
./firefox-bin -P Firefox2 -no-remote "$@"

  • I had to use FFDIR to make it work, needed the absolute path.
  • The -P argument tells firefox to run with the Firefox2 profile created in the previous steps.
• Modify /Applications/Firefox2.app/Contents/Info.plist. Look for the key CFBundleExecutable and change the string value from firefox-bin to firefox2.sh
• In my case, OSX had cached the contents of my Info.plist file somewhere and it ignored my modifications to it. To make it see my change I had to drag Firefox2 out to another location (I used the desktop) and then back into the Applications folder. I was going nuts trying to find out why my Info.plist file was being ignored and this fixed it.
• You should be able to run both version at the same time now. Firefox2 will use your custom script and pull the Firefox2 profile and Firefox3 will use the default profile (Firefox3).

As a final note, when you fire up Firefox3 it will appear that Firebug doesn’t run on the new browser. This is not the case, you can install the 1.1 version which will work with the Firefox3 betas at getfirebug.com.Home improvement loan missouri
