How to Clean Unnecessary Files in Firefox
- 1). Open Firefox if it's not open already.
- 2). Click the "Tools" option at the top of the window and select "Clear Recent History..."
- 3). Select the options you wish to delete in the "Clear Recent History" window. In a sense all of these options are for unnecessary files -- Firefox can delete all of them and operate just fine. If you feel any are necessary, only remove the ones you don't want.
- 4). Select the timeframe from which you want to delete the files. This is the timeframe during which the files were created and your options are the "Last Hour," the "Last Two Hours," the "Last Four Hours," "Today" and "Everything."
- 5). Click the "Clear Now" button to begin deleting the Firefox data files.
