I want to change the location of the temporary files corresponding to the web pages I visit. It seems to be called the cache.

Right now those files are saved in

   C:\Users\userid\AppData\Local\Temp\

but my C drive is a SSD and I don't want them to be there.

Note: In about:config, I created a string

   browser.cache.disk.parent_directory

and set its value to

   D:\Temp\Firefox_temp\

but to no avail: the temporary HTML pages are still created in C:\Users\userid\AppData\Local\Temp\.

5. In the Variable value Edit box you may specify the path to the directory that Windows and many other programs will use for temporary files.


Be sure and repeat that process for both TMP and TEMP.

You'll need to restart any running programs for the new value to take effect. In fact, you'll need to restart Windows for it to begin using the new value for its own temporary files.

Thanks a lot. It works.

I'm surprised that Firefox does not give more granular control. I have to change the TEMP not only for Firefox, but for every other application. In my case, it's perfectly what I want, though.
