I checked my system - Firefox wasn't writing much and what it is writing is going to my user directory on the hard drive instead of the program directory on the SSD, so that's nice. But still, I don't want my browser cluttering up my drive with unnecessary junk - history, persistent caching from previous sessions, old tracking cookies, nevermind a constant backup of the state of everything. I try to turn all that off, but there's always one more hidden thing like this. If I want to save something, I'll download it. If I want to come back, I'll bookmark it. Other than those two cases and settings changes, all of which are triggered by my explicit choice & action, it really shouldn't be writing/saving/storing anything. Would be nice if there were a lightweight/portable/'clean' option or version. When I tried Spotify, it was pretty bad about that too - created many gigabytes of junk in the background and never cleaned up after itself. I made a scheduled task to delete it all daily, but eventually just stopped using spotify.
