  • Support issues and questions are handled at /r/uMatrix
• I tried to reproduce the issue when...
  • [x] uMatrix is the only extension
  • [x] uMatrix with default lists/settings
  • [x] using a new, unmodified browser profile
• [x] I am running the latest version of uMatrix
• [x] I checked the documentation to understand that the issue I report is not a normal behavior

Description

Many times Scripts are cascaded through several domains. Many time I have to allow a script and after reload a bunch of new scripts appear in uB then I have to allow another script and again a bunch of scripts appear. I do not like it to try unblocking ressources part be part.

A specific URL where the issue occurs

On fanfiction.net/login.php you need to enable google recapcha.

Steps to Reproduce

1. Unlock scripts for google.com
2. Reload
3. Unlock scripts for gstatic.com If you try to login, scripts for gstatic.com create a frame to google.com
4. You have to unlock frames and XHR for google.com
5. Now you could log in

Expected behavior:

• [ ] uMatrix knows that I google.com is addressed with a specific resource the domain gstatic will follow.
  • [ ] uMatrix shows below of google.com gstatic.com as a dependency option
  • [ ] uMatrix shows a mark which tell which resource lead to which domain
  • [ ] uMatrix save this dependency and show them directly on next visit
  • [ ] uMatrix shows learned dependency immediately after revisiting a website. This dependency shows in gray instead of red or green until they are actively requested.

Mockup

Your environment

• uMatrix version: 1.4.0
• Browser Name and version: Firefox 75
• Operating System and version: Ubuntu 19.10

This involves re-writing large parts of uMatrix, I prefer to decline, and additionally, I do not think it is desirable behavior.
