A Tour Through TenFourFox's about:config

One of the coolest things about Firefox has been its about:config feature and its near endless array of preferences. You simply type about:config in the address bar, and it's like the keys to the kingdom. Turns out TenFourFox is no different and even has a few custom preferences of its own, so I thought I'd take a brief tour through some of the settings with an eye on speed enhancements.

First, type about:config in the address bar and make the obligatory promises not to break stuff. Then find the following preferences:

This is set to false by default. Double click on false which changes it to true, and you might notice the interface seems a little snappier.

When true, this raises the download manager window when a download starts. However, on my Sawtooth I noticed that blue animated progress bar takes about 20%-25% of my CPU, so rather than keep closing the window after it pops up, I just have it not open at all. I already have MenuMeters in my menubar telling me my network activity, so I already know something's downloading.


Don't want animated tabs slowing you down? Set this to false.

Speaking of tabs, here are a couple more:


This clips the width of your tabs when you have too many open, but it also eliminates the close tab button from all tabs except the one focused. The default value is 140 pixels. I switched mine to 80, and now the close button remains visible on all tabs.


Set this to true and click on the list all tabs button at the right end of the tab bar.

And one more:


Change the value to once. Then animations will only play once and won't loop and slow down your browsing.

There are also a few settings that are unique to TenFourFox. Just type tenfourfox in the filter bar and you'll see there are three for now. They have to do with disabling certain troublesome plug-in features, and the developer has promised there will be more settings unique to TenFourFox in the future.
