From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:0.9.5+) Gecko/20011022 BuildID: 2001102203 When I set the pref user.cache.directory by hand (editing prefs.js), about:cache still shows the default cache directory and no cache files are created in the specified directory. I see this on NT4 and W2K I see this problem in NS 6.1 as well, so it may have been around for a while. Reproducible: Always Steps to Reproduce: 1. Exit Moz/Netscape 2. Edit prefs.js, changing the value for browser.cache.directory 3. Save prefs.js 4. Run Mozilla 5. Browse some pages 6. Go to about:cache, notice the directory listed (not what you entered in 2). 7. Look at the cache directory you specified. There are no new files there. Actual Results: Specified cache directory not used Expected Results: Mozilla should use the specified cache directory

Yes, the prefs were not working properly for 6.1. This has been fixed for 0.9.4, however the new preference is "browser.cache.disk.parent_directory". The disk cache device will create a cache folder in the specified directory, this avoids most the worst side effects caused by users accidently specifying their root directory or some other important directory. On some platforms, cache files used to get sprayed all over the place or important files could get deleted when the cache was cleared.

This is a dupe of another bug.

The pref is now called browser.cache.disk.parent_directory. *** This bug has been marked as a duplicate of 78480 ***

VERIFIED, dupe.
