Is it possible to view the contents of Firefox cache and what is optimal size?
To view the information about and the contents of FireFox’s cache, simply type ‘about:cache’ into the address bar of the browser and select the ‘list cache entries’ option from the ‘Disk Cache Device’ section that appears. A better viewer can be downloaded as a plugin from Mozilla themselves from the following URL: https://addons.mozilla.org/en-US/firefox/addon/2489 There is not a definitive answer for the optimal size of the cache. Factors like hard drive size and types of sites visited (text only sites use far less space than graphically laden ones and so would fill up your cache less quickly) have to be taken into consideration. Mozilla set the initial cache size to 50MB and this should be ample for most users. If you are intent on collecting larger files, for example flash or shockwave animations, then you might want to set it to a larger size, but anything over 100MB is getting on for overkill really.
