Prerequisites

• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
  • I also searched the existing issues at https://github.com/gorhill/uMatrix/issues
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uMatrix
• I tried to reproduce the issue when...
  • uMatrix is the only extension
  • uMatrix with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uMatrix
• I checked the documentation to understand that the issue I report is not a normal behavior
• I used the logger to rule out that the issue is caused by my ruleset

Description

I am not able to add codesector.com domain to the "blacklist" on my virtual server, which I had imported. I can add to the list itself of course, but it has no effect in uMatrix, so I can still the site open.

I AM able to add www.codesector.com and this address is blocked then. I have also no problems to add other names in style domain.com. JUST this specific name codesector.com isn't possible.

Supporting evidence

Weird: in the GLOBAL view I CAN see the domain as blocked ...

Your environment

• uMatrix version: 1.4.1b6
• Browser Name and version: Firefox 77.0b2 (64-Bit)
• Operating System and version: Microsoft Windows 10 Pro x64 [18363.815] [1909]
