Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker

    I'm not sure about this, probably internal filter read, not external filters.

• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

When I added some network filter that include ~document exception, uBlock logger reported the filter that I've putted in is invalid

A specific URL where the issue occurs

No URL, just internal uBlock (maybe only logger?)

Steps to Reproduce

1. Open uBlock Dashboard
2. Go to My Filters
3. Try add some network blocking and include ~document exception, e.g.
   ||example.com/page$~document
||example.com/page$important,~document

Expected behavior:

uBlock Logger doesn't reported as invalid, probably the network filter is usable.

Actual behavior:

uBlock Logger reported the filter is invalid

3\. Try add some network blocking and include `~document` exception, e.g.
    `||example.com/page$~document`
    `||example.com/page$important,~document`

Expected behavior:

uBlock Logger doesn't reported as invalid, probably the network filter is usable.

What you think this filter should do?

What you think this filter should do?

To block everything except document (aka. page load)

Example from real use, when I block ||facebook.com/ads/$~document will be block other requests except documents to allow me accessing specific pages like https://www.facebook.com/ads/preferences

[gorhill]

Using ||facebook.com/ads/ will block all matching network requests and will not block document, so no need to add ~document.
