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 copy and paste the following code into the address bar of Mozilla Firefox to access the setting directly.

about:config?filter=toolkit.winRegisterApplicationRestart

The value for both settings above is set to ‘False’ by default, which means the feature is disabled. To change the value, simply double-click the entry in the about:config screen. As long as 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.
