When I go to Network Preferences and hit Clear Now for Cached Web Content, either of the following happens: It goes from 350 to 348. Then trying again nothing happens. Or It stays on 350 and nothing happens.

Firefox 38.0.1 Yosemite 10.10.3

Do you mean the actual cache size, for example, mine says --

Your web content cache is currently using 1.6 MB of disk space

-- or the amount in the box below that line only decreases from 350 to 348?

In case this is a problem with the new "in tab" version of the Preferences dialog, do you want to try using the old one? Here is how you switch back:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste pref and pause while the list is filtered

(3) Double-click the browser.preferences.inContent preference to switch it from true to false

Does that make any difference to whether the checkbox is enabled?

(Note: I don't know whether the old dialog will be in Firefox forever or is a transitional feature. As you've probably noticed, the long-term trend is to remove things that pop up.)

What does the about:cache page report?

Do you see all three caches (memory, disk, appcache)?

Make sure that you do not run Firefox in permanent Private Browsing mode (Never remember history).

  • Tools > Options > Privacy > Firefox will: "Use custom settings for history"
  • Deselect: [ ] "Always use Private Browsing mode"

You can try to delete the Cache2 folder on the hard drive. You can find the location on the about:cache page.
