For those who are not familiar with this modification, in Firefox's URL window, type About:config. This will bring up the configuration editor.
Most of the below settings do not exist, so they will need to be created (right click, create...). Where a number value is desired, create an integer. Where a true/false is desired, create a boolean.
I'm going to start-out with a test of the following settings,
nglayout.initialpaint.delay = 2000 ms (previous value not existent)
content.notify.ontimer = true (previous value not existent)
content.notify.interval = 1000000 us (previous value not existent)
content.interrupt.parsing = true (previous value not existent)
content.switch.threshold = 100000 us (previous value not existent)
browser.cache.memory.enable = true (previous value already true)
browser.cache.memory.capacity = 4096 (previous value not existent)
browser.sessionhistory.max_total_viewers = 0 (previous value -1)
config.trim_on_minimize = true (previous value not existent)
@elianda, when your machine is available, please let me know what settings you decided were the most optimal for your (rather fast) Pentium 166MMX. I'm using a significantly slower Cyrix 5x86-133 (~Pentium100).
EDIT: Well, I don't really know how fast Firefox was before the mods (I'd need to get out a pocket timer), but it still isn't quite as fast as IE6. Has anyone else played with these settings? If so, what was found to be most optimal on a 486? Thanks.
Plan your life wisely, you'll be dead before you know it.
