Don't know how to pause/resume downloads (in browsers) (Mozilla Firefox)

1. Click the Downloads icon and select Show All Downloads
   
   

   

2. Once the Library window appears, right-click a downloading file and select Pause
   
   

   

Repeat the previous steps if you wish to resume downloads (click Resume instead of Pause)

Click the small Downloads icon while a file is being downloaded -> Right-click the file whose downloading you wish to pause -> Select Pause

The procedure is the same if you wish to resume the download (in that case you will only click Resume instead of Pause )
