Thread: Limit/Reduce Mozilla Firefox Memory Consumption

Limit/Reduce Mozilla Firefox Memory Consumption

Although popular browsers, Firefox is not a lightweight browser. This browser is quite fat and wasteful, because it spent a fairly high your computer resource. For the first time you run it the browser can spend at least 20MB of memory on Linux, and 30MB on Windows. The more you open tabs / web then the greater memory will be used and your CPU work hard to process the data.



But do not need to be discouraged and hastily decided to move to another browser. Because with a little tune up you can conserve and speed up your Mozilla Firefox.

1. Limit your memory cache capacity Every time you open a web page, Firefox will automatically saved in the cache memory. By default Firefox uses the maximum amount of RAM you have. That’s why the more you open the web, your computer’s memory is depleted. To limit the options add: browser.cache.memory.capacity. The trick, right-click, New> Integer. Type browser.cache.memory.capacity, enter the number 2048. 2048 here means use the maximum memory cache only 2 MB. You can try with another number, but try a multiple of 1024.
2. Limit your capacity of the cache history
   Just as cache memory, the only difference here by Firefox cache allocation is intended to speed up loading pages when you press the button on the browser back and forward.
   If you rarely use back and forward, you’ll want to set a small value in order to save memory. In the filter type: browser.sessionhistory.max_total_viewers, change the value of -1 to 3. Default -1 means to use as much RAM available. hmm .. The default value of Firefox is really greedy isn’t it?
3. Limit your disk cache capacity
   By default Mozilla sets the disk cache size of 50 Mega. Surely this is waste of memory. Setting it to 2 MB to provide a positive performance, especially for computers with 128 MB of memory and hard disk under the old model. In the filter type: browser.cache.disk.capacity, change the value of 50 000 to 2000.
4. Limit your extension / add-ons
   More add-ons that you use, the more RAM is spent. Disable add-ons that you don’t use. To compare the performance of memory used when using and without add-ons can be done by trying to run Firefox in safe-mode conditions. The trick with the command: $ firefox-safe-mode. At the option that appears make sure you check the option: Disable all add-ons.
5. Disable Flash
   Did you know that flash animation that is loaded when you open a web resource consuming sizable RAM? The consequence is the loading time is slower and heavier. Even the flash plugin prior to version 9, RAM resources used by an accumulation of the amount of flash which opened earlier. Hot? A good idea to disable the flash.
6. Disable download history
   We recommend that you disable the feature of this history. More download history was stored, it will reduce the performance of Firefox. Select the Tools menu> Options> Privacy. Then remove the option to “Remember what I’ve downloaded”
7. Load the necessary links
   By default Firefox without you know, doing pre-download on web page links are likely to be clicked. This tactic mimics Google’s first result cached advance of a search link that found. Of course it will be wasting your bandwidth, and CPU performance. To disable this feature type in the filter: network.prefetch-next, click twice, for its value to false.
8. Download and display immediately.
   These tips may be useful for the impatient users. Generally Firefox will wait a while after downloading to start displaying the page. To force Firefox to display immediately the web page, you can set the value of nglayout.initialpaint.delay to 0. If there is no feature then right click, New> Integer> the fill nglayout.initialpaint.delay with its value

Adding tips to save other memory is to enable the feature of config.trim_on_minimize. But this feature only work and effective in Windows OS. To activated this trick, right-click, New> Boolean, type config.trim_on_minimize. Set the value True. In this way every time Firefox in minimized, automatic memory in use will be removed / released, so it can be used to process another application. OK, if all has done, the last step is to restart your beloved Firefox.
