Tips and Tricks

You can change the setting in Preferences → General → Tabs unchecking the “Open links in tabs instead of new windows” so that firefox opens new windows instead of tabs. The advantage of this setting is that each window shows up in the list of open apps in the phone shell making it easier to switch between them and close them.

Firefox tends to consume a healthy amount of RAM for each tab/window. Close ones that you are not using.

Web apps can be given access to desktop notifications that are included in the list from other apps such as Chat when you click the top menu bar. This is useful for certain web-based instant messaging systems.

The reload button is not visible on the menu bar. However, you can press and hold on the tab at the top to reveal a context menu where reload is accessible.

The above screenshot is using Firefox with the density setting “Touch”. With this setting the back button, the tabs and the address field are larger and therefore, are easier to touch. Please use Customize (in the Hamburger menu) → Density → Touch → Done if you want to have this setting.

To make Firefox scroll more smoothly, go to about:config and set layers.acceleration.force-enabled to true. Some users have reported stability issues with this setting.
