Today I found the solution mentioned at the How To Geek’s blog. He mentioned a setting in about:config that was specifying the time between the high and load frequency interrupt mode. Firefox changes modes depending on a user’s activity on a website. High Interrupt Mode interrupts the website parser more frequently for better responsiveness of Firefox while Low Frequency Mode loads the website faster but is unresponsive.

Type about:config in the address bar of Firefox and filter for the string Content.switch.threshold. If the key does not exist create a New > Integer with the name Content.switch.threshold and the value 1000000. The default value for the key is 750000 which caused the problem in first place.

The related keys content.notify.ontimer and content.interrupt.parsing must be set to TRUE, the preference would not have an effect otherwise. The value 1000000 sets the threshold value to 1 second which makes Firefox more responsive but increases load time slightly.

It begins by explaining profiles, general appearance of items in firefox, followed by an in depth explanation of firefox options. After that the editor compiled a list of firefox extensions that he uses (extensions are addons for firefox that increase functionality).

The final part explains advanced configuration elements like about:config and explains some of the options you can change to make firefox even faster.

Everything is explained in word and with screenshots making this an ideal guide for the visual type of reader. I´am using most of the authors suggestions and I encourage you to take a look as well and change firefox the way you want it to be.

Great guide for every firefox user.
