1.) What is FireTune?
FireTune is a free software application that allows to easily optimize several configuration settings for the Mozilla FireFox webbrowser. FireTune is based on an article on TweakFactor (
http://www.tweakfactor.com), however - similar optimization guides can be found on lots of Firefox related websites. Actually it automates the procedure of optimizing the browsers preferences for faster browsing with the FireFox webbrowser.
2.) What does FireTune do?
Instead of changing all relevant preferences of FireFox manually as described in the TweakFactor tweaking guide for FireFox, you can use FireTune to automatically apply all the configuration changes to FireFox.
Performance Settings
One of the limitations of pretty much all computer applications is the need to target for a general audience because of the wide array of computer components and varied network infrastructure. This is where tweaking comes in. Firefox by default is aimed at a general audience too and hopefully we can tune it more to the needs of theindividual. The majority of the information comes from this excellent thread over
at the MozillaZine Forum. The first post in particular goes through in great detail what each of the settings do. The thread however gets fairly long and convoluted and we attempt to summarize the contents of this thread along with a couple other sources into something that is easier to digest. As with the settings on the previous page, the contents are copied into the user.js file. We do not go into major detail about the setting as the thread goes into detailed explanations of what the settings mean in the first post. Instead, the configurations are culled from the thread of what people have reported to have worked for them along with some modifications on our end.
Quick and Dirty Settings (not included in FireTune, as part of the tweaks below).
user_pref("network.http.pipelining", true);
user_pref("network.http.pipelining.firstrequest", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("nglayout.initialpaint.delay", 0);
These were some settings I ran across sometime ago. Pipelining does multiple data requests at once and should speed things up. I believe IE did this before and this was partially attributable to the speed advantage that IE had over older versions of Mozilla/Netscape. Initial Paint Delay actually slows down the rendering of the ENTIRE page but since users tend to start reading before the entire page is rendered, setting this to a low value gives the impression that the page loads faster.
The following configurations are based off of recommendations off of the Mozillazine thread with some editing on points that I do not agree with Common to all configurations.
These are the settings that seem to be common to all configuration files regardless of connection speed or computer speed with a couple of additions - plugin paths can be found with about
lugins and the bookmark menu delay is turned off.
user_pref("network.http.pipelining", true);
user_pref("network.http.proxy.pipelining", true);
user_pref("network.http.pipelining.maxrequests", 8);
user_pref("content.notify.backoffcount", 5);
user_pref("plugin.expose_full_path", true);
user_pref("ui.submenuDelay", 0);
Fast Computer, Fast Connection:
Definitions:
Fast Computer: is a machine with a CPU greater than 1.5Ghz and with memory installed of at least 512MB RAM
Fast Connection: is a DSL, cable or a better connection.
user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("browser.cache.memory.capacity", 65536);
A couple settings of note - Firefox is allocated 4096 KB of memory by default and in this configuration we give it roughly 65MB as denoted by the last line. This can be changed according to what is used.
Fast Computer, Slower Connection:
This configuration is more suited to people without ultra fast connections. We are not talking about dial up connections but slower DSL / Cable connections.
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);
Fast Computer, Slow Connection:
user_pref("browser.xul.error_pages.enabled", true);
user_pref("content.interrupt.parsing", true);
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.maxtextrun", 8191);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("nglayout.initialpaint.delay", 0);
user_pref("browser.cache.memory.capacity", 65536);
Slow Computer, Fast Connection:
user_pref("content.max.tokenizing.time", 3000000);
user_pref("content.notify.backoffcount", 5);
user_pref("content.notify.interval", 1000000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 1000000);
user_pref("content.maxtextrun", 4095);
user_pref("nglayout.initialpaint.delay", 1000);
user_pref("network.http.max-connections", 48);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 16);
user_pref("network.http.max-persistent-connections-per-server", 8);
user_pref("dom.disable_window_status_change", true);
One of the changes made for this particular configuration is the final line where the status bar is disabled for changing web pages to save processor time.
Slow Computer, Slow Connection:
We have entered the doldrums of the dial-up user
user_pref("content.max.tokenizing.time", 2250000);
user_pref("content.notify.interval", 750000);
user_pref("content.notify.ontimer", true);
user_pref("content.switch.threshold", 750000);
user_pref("nglayout.initialpaint.delay", 750);
user_pref("network.http.max-connections", 32);
user_pref("network.http.max-connections-per-server", 8);
user_pref("network.http.max-persistent-connections-per-proxy", 8);
user_pref("network.http.max-persistent-connections-per-server", 4);
user_pref("dom.disable_window_status_change", true);
Some of the options we chose not to include as opposed to suggestions on the Mozillazine threads included the suggestion of catching SSL pages. Regardless of computer speed, one of the common trends is that pipelining is a good thing. Those with faster computers and gobs of memory may want to up the amount of memory available to Firefox while those with slower computers can still increase the default 4MB to something higher. This was not done in our configuration files however. Powerusers are also welcome to disable the status bar to eek out thatextra CPU cycle or two.
3.) Usage instructions:
FireTune is very easy to use. The only thing you need to do is to create a backup of your current Firefox configuration file (you can do that easily with FireTune's backup feature), then make your selection from the available tuning options. FireTune will optimize Firefox according to your selections.
· Close FireFox
· If you have not created a backup of your configuration file before, you should do that now
· After creating a backup of your configuration file, make your section from the available optimization settings. For details on the different options, please check the section above
· Click the 'Tune it!' button
· FireTune will then optimize the Firefox configuration file accoring to your selections from the option list. Once the optimization is done, you may restart Firefox
· Please note that FireTune does not show what optimizations you have chosen last time you used it. Do also note that you must re-select a user profile before you can change its configuration again using FireTune.
