Using Firefox Flag

Launch Mozilla Firefox, type about:config in the address bar and hit Enter, When prompted with a warning message, ignore it and proceed further by hitting ‘I accept the risk’ button.

Next scroll down to find the following entry,

toolkit.winRegisterApplicationRestart

Or, you can copy the above entry and paste it in the ‘Search’ bar located at the top.

When found, double-click it to change the value to ‘True’.

Alternatively, you can simply copy and paste the following code right in the address bar of Mozilla Firefox to move directly to the setting.

about:config?filter=toolkit.winRegisterApplicationRestart

The value for both the settings above is set to ‘False’, by default. This means the feature is disabled. All you need to do is simply double-click the entry in the about:config screen to change the value from false to true. So long the value is set to true, the feature will remain enabled. Should you wish to disable the original configuration follow the same procedure and set the pre-configured value to false.
