Mozilla Firefox is primary browser I use with my Ubuntu Gutsy but like any software it has benefits in line with drawbacks. Of course there are more benefits in Firefox (I really think so) but here are several tips that would help to improve Firefox’ performance and make it working even better. These tips were found at Zepy (nice site I must say 🙂 ) and you can read them in details here.
Fetch only pages that you click (disable links prefetching): Type “about:config” at the address bar and hit return. Then enter “network.prefetch” or “network.prefetch-next” in the filter field and make it FALSE.
Limit the RAM usage (really makes sense for me): Type “about:config” at the address bar and hit return. Filter up your search after “browser.cache” and select “browser.cache.memory.capacity” from the remaining options (if there is no such item you can create it) and put desirable value in KB. For example to set limit of 128 MB you should put 6144 (please follow table below to get proper value). Quick note: browser.cache.memory.enable must be TRUE for this preference to take effect.
|Physical RAM||Memory Cache (in KB)|
|8 GB and up||32768|
