No operation, extension stops working after some time

[amithm7]

Problem:

• No right click context menu is created.
• No default operation.

Observations:

• Background script is shown as stopped in debugging.
• Changing options / preferences starts the background script.
  • Context menu is created.
  • Actions work as long as script is running.

Potential solutions:

• Use persistent background script? (unsupported on next manifest version 3)
• Use content_scripts to target urls?
