Step 2. Create association of Mozilla Firefox with MON files

However, it may happen that the application itself does not cause the MON file to open in the Mozilla Firefox application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program.

Step 3. Update Mozilla Firefox to the latest version

Step 4. Check for the following problems with the MON file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The MON file may be unusually small compared to the original file. This is most often caused by a problem while downloading the MON file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file MON or the program directory. However, remember that not every infected MON file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the MON file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular MON file corruption. You can restore the file from a backup or use Mozilla Corporation help.
The program indicates that the file is encrypted or corrupted. The encrypted MON files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. It is best to move MON to a different directory.
This problem only occurs with more complex files. In this case, the MON file is blocked by the first application to open it. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the MON file again. However, some background programs may block the MON file while scanning. If the problem persists, restart the machine.
