When you are using some of the different computer programs you will find they want to change your permissions to work properly. This is when you will want to change those back, though, when you are not using the program and of course the program does not do this for you. To help you in changing these back, you need to get into the permissions and this can be a tricky thing depending on what you are using. When you are using Firefox, though, you can do this easily by using the Open about:permissions.
By using this, you can easily access your permissions and be able to change these around. Then you can start to have your computer working and know it is going to be working specific to what you need to have. Without this, you will have more trouble then what you think because the permissions are always located in a different place on each program that you use and this means you can easily spend hours trying to track down all of the information which you need to change these back.
