Trying to find a way to move the browser cache dir in FF 45.01 - currently disabled to reduce wear on my SSD. I want to move the dir to a ramdrive, however the browser.cache.disk.parent_directory line in about:config is no longer there.

How can I move the cache dir to a new location?

Ta muchly,

You can create the pref manually and then enter the desired path. Note, the target directory must exist before.

Thanks christ1 - this put me on the correct path, although slightly more detail would have been useful. The sequence I used to fix the issue was:

open 'about.config' right click anywhere on bcakground, select new enter 'browser.cache.disk.parent_directory', click ok enter '<path to temp dir in ramdrive or other drive> [note - directory MUST Pre-exist> click OK RESTART FIREFOX check path in 'about:cache' use preferences to adjust cache size as required

Job done.

Again - thanks for the tip :D

You can consider to use the portable Firefox version.

The portable Firefox version is specially configured to run with a removable drive or with SSD devices to limit write access to the device.
