Different from the desktop, mobile browser tabs may not be cleaned up in time, which means that some background processes will continue to consume memory and increase battery consumption. Firefox 81 for Android platforms is about to introduce a feature that automatically closes tabs that are no longer accessible on a timed basis, depending on user settings.
As themedia GHacks points out, this new feature is disabled by default in the Firefox 81 update, but provides several options in the settings. For example, if a user allows tabs to be closed one day, a week, or a month later, Firefox will automatically process them.
This means that the browser closes inactive tabs based on your settings. So for example, if you choose a month, Firefox can close tabs that have been loaded in the browser but that users haven’t clicked on in the last month. In other words, this feature is more like a tag cleanup tool that can help with old pages that you no longer need.
While this update won’t make much difference to those who prefer to be organized and run only two or three tabs in a browser at the same time, it will certainly help for those who open each page in a new tab and forget about it.
