Heavy SSD Writes from Firefox
Chrome, on my system, is even more abusive. Watch the size of the .config/google-chrome directory and you'll see that it grows to multi-GB in the profile file.<p>There is a Linux utility that takes care of all browsers' abuse of your ssd called profile sync daemon, PSD. It's available in the debian repo or [1] for Ubuntu or [2] for source. It uses `overlay` filesystem to direct all writes to ram and only syncs back to disc the deltas every n minutes using rsync. Been using this for years.  You can also manually alleviate some of this by setting up a tmpfs and symlink .cache to it.<p>[1] <a href="https://launchpad.net/~graysky/+archive/ubuntu/utils" rel="nofollow">https://launchpad.net/~graysky/+archive/ubuntu/utils</a>
