FireTune for Firefox 1.x
FireTune optimizes firefox according to your computer and internet speed. Suppose if your system is slow but you have a very fast connection then firefox is optimized accordingly. There are different pre configured settings like slow pc slow connection, slow pc fast connection, fast pc fast connection etc.
Firetune does not modify the firefox executable or any other binary file instead it makes some change in the profile folder, which can be backed up before making any changes.
There is also a neat feature, to start firefox faster with the Windows XP prefetcher option. Firetune creates a desktop icon named “Firefox FastStart” using which firefox can be started quickly.
One more thing is firetune is compatible with the latest (pre)release of firefox 1.5
