For some reason when a page is loading in Firefox, it doesn't seem to respond to user interaction immediately. For example, say you're loading a very long page (maybe you're using a free Backpack account), and you know that the content you need is half way down the page. By default, Firefox will ignore user interaction in favor of giving all processing power to page rendering. It may well be that Firefox's engineers made this decision for a very good reason, but what if it bugs you that Firefox ignores you when you know exactly what you want to be doing? Well, it turns out there's a hidden setting in Firefox that will allow you to bend it to your will.
Firefox uses two priority modes when rendering a page: a low-priority mode that often checks for user input, and a high-priority mode that prioritizes page rendering over user input. There is a timer that determines how long Firefox will wait for user input before switching to high-priority rendering mode.
The Geek at How-To-Geek researched this setting, and determined that switching the default value from 750000 to 1000000 is a good balance that allows for a more responsive feeling browser, while still giving an adequate amount of time to the high-priority mode.
To make this change yourself, type about:config into your Firefox address bar, then type content.switch.threshold into the Filter field. You will likely not have any results returned. If the setting already exists, simply switch the value from the default 750000 to 1000000. If it doesn't, right click anywhere in the window and choose New > Integer. Use the following setting:
- Key Name: content.switch.threshold
- Key Value: 1000000
