Problem
The file logging plugin allows users to store the logging information in a separate file. The logging level can be selected and the options menu will be extended.
Prerequisites
The file logging plugin can be downloaded from the Firefox add-on manager, using the following url: https://addons.mozilla.org/.
Solution
There are some extra buttons visible in the log panel after installing the plugin. We can select the level of logging and choose if we want a timestamp.
