For reference. Here is what is currently being used on my sole Windows 7 box running the latest version of Firefox I've modified heavily. In other words, it's much worse in the default install. This is what is being dumped every 15 minutes from the RAM disk. So it's between 5-15 minutes out of day most likely.

This does not include anything else in the real %APPDATA% directory living on the C: drive. The only thing I've directed to RAM disk+HDD backup on this machine is Mozilla firefox's directory from %APPDATA%.

Monitoring the firefox process it's constantly writing to RAM disk at 0.2MB/s. Even when the browser is "idle" on flat HTML webpages.

Currently I have 8 tabs active. Two of which are on youtube (two videos that have been paused for over an hour), 5 threads on 4chan (of which only 2 are auto updating) and a searx web search. The other 40-odd tabs are not active because they were unloaded by Auto tab discard. I am running ublock origin, noscript and a handful of other quality of life add-ons. All of which should not be doing anything that requires hammering the disk this much.

The more "modern" the webpages the more they hammer the disk. But even old school web 1.0 flat HTML pages show this behavior. Since it isn't simply caching web pages or javascript. It's constantly writing shit to the .profile directory and usage stats and who the fuck knows what else. There are tons of .json files and things contained within these directories which are sent back to mozilla's servers 24/7.
