So I'm not sure how to search this, I couldn't find anything after trying...so apologies as I'm sure this is covered somewhere. Anyway, when I wake computer from sleep, Firefox is often unresponsive while disk activity is maxed - so I think what's happening is it's storing pages/tabs to disk and reloading them (slowww*) vs just getting them fresh from the web. If I have diagnosed this right, is there a setting that can be changed to disable this? (I already tried browser.cache.disk.enable -> false - this had no effect). Thanks in advance. *Yes this is an old drive not SSD but for crying out loud I shouldn't have to upgrade hardware for this, in theory at least....
