How to Restart Firefox Browser Automatically After a Preset Time

Mozilla Firefox is considered one of the most secure and configurable web browser. This is why it is so popular is the first choice of the security experts. But it is a big memory hog and can quickly consume nearly one gigabyte of your system memory. If you have large physical memory (RAM) modules installed then you do not really have to worry about the memory consumption from Firefox. But if your computer has only 1 GB or 2 GB of RAM installed, then Firefox can make your system a little sluggish after continued use over many hours. One of the tricks to reduce memory consumption of Firefox is MemoryFox, but that works only on Windows computers. You can also use the Time Restart extension for Firefox to keep restarting the browser after a preset amount of time duration and keep it at the lower end of the memory consumption scale.

You can also this screen by from the menubar by accessing Tools → Add-ons. On the Add-ons screen, you can open the options for the Time Restart extension by clicking on the Options button next to it.
