Question: With FF Quantum [eg, 61.0.2 (64-bit)] is it no longer possible to completely stop FF caching to SSD/HDD?
- Solving the Slow and laggy Firefox problem
- Troubleshooting Firefox
I then did:
Refreshed my test FF profile AND also deleted existing
prefs.jsto hopefully guarantee there were no historical
about:configsettings that might interfere / corrupt this experiment.
browser.cache.memory.enableis set to
Created new Integer entry
browser.cache.memory.capacity& set it to
-1for automatic cache size selection
Observed that instantly a new
memory Number of entries: 4 Maximum storage size: 29696 KiB Storage in use: 56 KiB Storage disk location: none, only stored in memory List Cache Entries disk Number of entries: 4 Maximum storage size: 29696 KiB Storage in use: 56 KiB Storage disk location: none, only stored in memory List Cache Entries appcache Number of entries: 0 Maximum storage size: 0 KiB Storage in use: 0 KiB Storage disk location: none, only stored in memory
...which would seem to be complete poppycock given my #9.
Profile: default This is the profile in use and it cannot be deleted. Default Profile yes Root Directory /home/kdemeoz/.mozilla/firefox/p0r3dfxw.default-1536906901716 Local Directory /home/kdemeoz/.cache/mozilla/firefox/p0r3dfxw.default-1536906901716
...which conforms with my #9, contradicts #10, & thus implies an apparent impossibility to completely* prevent FF-Q from caching to disk.
- * Apparent partial solution: Created new String entry
browser.cache.disk.parent_directory& set it to
/tmp[which of course is a Ram-drive via tmpfs], undid #2, closed FF, repeated #7, launched FF, observed with exasperation that another new
/home/kdemeoz/.cache/mozilla/firefox/was created, BUT this time one of its previous subdirectories,
cache2, now was created instead as
/tmp/cache2/. That still leaves, perplexingly, these written to disk:
