Fed up with deciphering about:config options, or reluctant to dig deep into Firefox’s configuration files just to speed up your browser? FireTune, a free tool from Total Ideas Software, may well be the answer. It safely and automatically tweaks your Firefox settings to make the most of your computer and Internet connection, which might just shave a few minutes of loading time from your day.
For Windows XP users, there is an option to create a special “Firefox Fast Start” shortcut which uses XP’s prefetching features to enable Firefox to start up faster.
This is an essential tool in the arsenal of any Firefox user and something I’d recommend to anyone.
In a similar vein, TNK-Bootblock offer an Adobe Reader speedup tool, which will prevent the program from loading little-used plugins every time you open a PDF file.
