OK, I can't clear my Firefox (45.0, Mac 10.11) cache. Well, it's really hard ...
Clear The Cache Firefox For Mac
I go to Preferences/Advanced/Network, where I'm presented with a 'Clear Now' button. Looks good! I hit that and my cache (listed as 303MB) drops to 299MB. I hit it again, and it drops to 287MB. I hit it again, again and again and each time it drops a little bit. This is NUTS! I want one button hit to drop it to ZERO. I don't want to have to hit that stupid button fifty times to clear my cache. What's going on???? This happens EVERY TIME I want to clear my cache.
