I have had no problems with any performance issues with it. On that page it says that it is recommended and that "Firefox only recommends add-ons that meet our standards for security and performance.". It looks like I will have to put the Firefox profile directory on a ramdisk to fix this, softlinking the password files to the HDD, because they are the only thing I care about getting written to disk straight away. Every chance I have tried on the about:config settings to try and fix it hasn't worked, got rid of session restore etc, no dice.

This writing all the time behaviour has led to Firefox being called a 'SSD killer' a few years ago when SSDs were not as durable as they are now. One of my bigger annoyances with Firefox at the moment is that it writes to the cookies.sqlite and cookies.sqlite-wal files consistently every few seconds. This is just what worked for me, so YMMV, it only might work for anyone else. IIRC the about:config changes were changes to various cache setttings, but one of the more surprising things was that not having disk cache enables significantly reduced memory usage, no idea why, maybe Firefox's bookkeeping code for stuff cached on disk used a lot of memory for some reason. I had some issues with Firefox memory usage quite a while ago, tweaking about:config and using the Auto Tab Discard addon made it much better.
