FireTune is a Firefox add-on, which aims at optimizing the speed of the browser by changing its settings based on the user's preferences. The user is first invited to choose from a list what best describes his/her computer configuration such as "fast computer / fast connection", "slow computer / fast connection", etc. FireTune then attempts to adjust the settings of Firefox to best matches the user's computer - thus improving the performances of the browser.
As of 17 December 2009, Totalidea no longer distributes or supports FireTune. According to the Totalidea website:
"Because the Mozilla Foundation disallows us to show the Firefox logo within our FireTune software, we are no longer able to distribute FireTune, otherwise we would face legal actions initiated by Mozilla. Because of that we have removed the FireTune product from our product catalogue and do no longer offer it for download. Downloads of FireTune from third party websites are out of our control."
