If you hadn’t noticed yet, Firefox 4 now runs in 64-bit mode by default (at least on Mac anyway). I’ve noticed that Firefox uses up almost double the ram in 64-bit mode compared to when running in 32-bit mode. Also, some plugins (like Silverlight) are not yet compatible with the 64-bit mode of Firefox.
Update: running in 32-bit mode will also help with a known problem with Java MIME types not being recognized correctly.
Here’s how to run Firefox 4 in 32-bit mode (by default) on Mac OS X:
Using Finder, navigate to your Applications folder and locate the Firefox app.
Command+Click (or Right-Click if you have a 2+ button mouse) and go to: “Get Info”.
Check the box that says: “Open in 32-bit Mode” and close the Firefox Info box.
Quit and then Relaunch Firefox.
It’s as easy as that!
Note that 64-bit Firefox does run faster than 32-bit Firefox, but you probably wont notice that much of a difference, and you will reap the benefit of less memory usage, which can be crucial if your system is always low on RAM.

I have been using a Mac Mini at work now for several months. I use a PC mouse and keyboard (for several reasons, namely i have big hands and fingers so using those tiny Apple keyboards is out of the question, and I like my multi-button mouse too much to give it up). If you are curious of the model, I use a Logitech Cordless Desktop LX710 Laser (keyboard/mouse combo).
As is expected, both the right and left mouse buttons work correctly “out of the box” on OS X, but the extra buttons and the horizontal scroll do not work! This has annoyed me for far too long and it was time I did something about it:
The Failed Attempt
First I tried searching Logitech’s website for drivers and/or software to fix the problem. I had done this before, but figured I’d give it another go. Nothing… So I tried Google… Oddly enough Google supplied me with a link to Logitech’s website — apparently they have a “Logitech Control Center” just for Mac’s.
I was excited that it could be so easy to fix, so I quickly downloaded the program, installed it, rebooted, and… LCC told me that no compatible mouse/keyboard found. I rebooted again… Same result… I did some more in-depth searching and discovered that this program is for the Mac versions of the Logitech devices only (which explains why when I registered my product the actual model I have was not to be found in the drop-down).
The Successful Attempt!
I decided I had enough and searched Apple’s download page under the “Drivers” section. I had read about a utility called “SteerMouse” when trying to troubleshoot the LCC (funny…in those searches it was SteerMouse people complained about as it apparently interfered with LCC — obviously not the case for me lol), so I thought I’d see if it still existed or if perhaps there were other options.
Sure enough, there was SteerMouse. I downloaded, installed, rebooted. Then I started up SteerMouse and was surprised to see that it did not detect a compatible mouse, however it knew enough to instruct me to remove the LCC as that was interfering! I uninstalled the LCC and rebooted.
I was pleasantly surprised to see SteerMouse now detected my mouse and allowed me to change settings for every feature. And the best part? Not only did it work flawlessly, but it already had my preferred settings set as default from the start!
So I was looking for a book that I needed for a class (an old APA Manual) and came across my old (about 4 years old) Logitech Wireless Mouse. I do all of my school work upstairs in my “office” on my 17″ Acer laptop (running Ubuntu of course).
I plugged in the USB receiver and pushed the power button on the bottom of the mouse. The mouse worked just fine – as expected.
What surprised me (just a little bit) was that the extra buttons (it’s a 5 button mouse) worked instantly (no special setup needed). Click one and the browser page goes back one, click the other button and it goes forward… nice!
I also noticed that the side-scroll (tap the scroll wheel to the left or right) works not only in Firefox (tested by adjusting the window dimensions to force side scrolling necessity), but it also adjusts the volume on VLC media player! I wonder what else this little baby can do!
