Anyone used Profile Sync Daemon?

Profile Sync Daemon is a tool to move the web browser profile to RAM, using tmpfs, which has the advantage of reducing disk writes (useful for SSDs, some would say), increased speed and responsiveness.

The tool supports most browsers: Chromium, Google Chrome, Firefox (stable, beta, aurora and firefox-trunk), Conkeror, Midori, Opera (including Opera Next) and Qupzilla and is based on an old script (we’ve covered it on WebUpd8 back in 2009), with some extra features: this is a daemonized script and has recovery protection, as well as support for all the above mentioned browsers as opposed to the old script which only supports Firefox. It’s also a lot easier to use.

Since RAM content is cleared on reboot, Profile Sync Daemon automatically syncs the profile back to the physical disk using a symbolic link and rsync at a given time interval. Further more, the profile is synced back to the hard disk before you shut down or restart your computer, so no profile data is lost. Still, use it at your own risk!

I use it on one of my laptop which has a crucial m4 ssd.
It seems to work correctly, though i don’t see the effect on speed.
