First of all, if you want to decrease Firefox load time, remove all addons that you installed on it. All addons must be loaded during the load time and most of them are heavy enough to increase load times by a scale of seconds.

Also, you can find some tutorials that promisses increase Firefox performance. Take a look at these links:

If you want to increase the startup speed on Mozilla firefox, maybe you can do these steps:

  • Defragment your hard drive. (If using Windows, you can found in the Start Menu ---> All Programs ---> Accessories ----> System Tools ----> Disk Defragment.

  • Remove all the History, Cookies, and Cache, then check the applicable options, or in the Mozilla Suite preference ("Advanced -> Cached Web Content, click clear now").

  • Clean your bookmarks.

then restart your browser..


Reduce firefox cold start to warm start time:

Put an shortcut to firefox in the autostart directory in which you add -silent (using Properties of the shortcut), e.g. C:\Program Files\Mozilla Firefox\firefox.exe" -silent.

In the case, that you get a recover prompt at the beginning, set browser.sessionstore.resume_from_crash in about:config to false. (This does not affect your recover ability, e.g. if you use "SessionManager", you can easily restore your last session - but you are not asked automatically; in SessionManager you need to additionally tick use browser's built in crash recovery prompt).
