Built-in Badware risks disable Context-menu Copy (greyed out) on Firefox 121

[quimnuss]

Prerequisites

• This is NOT a YouTube, Facebook or Twitch report.
• I read and understand the policy about what is a valid filter issue.
• I verified that this issue is not a duplicate. (Search here to find out.)
• I did not remove any of the default filter lists, or I have verified that the issue was not caused by removing any of the default lists.
• I did not enable additional filter lists, or I have verified that the issue still occurs without enabling additional filter lists.
• I do not have custom filters/rules, or I have verified that the issue still occurs without custom filters/rules.
• I am not using uBlock Origin (uBO) along with other content blocker extensions.
• I have verified that the web browser's built-in blocker or DNS blocking (standalone or through a VPN) is not causing the issue.
• I did not answer truthfully to ALL the above checkpoints.

URL(s) where the issue occurs.

It's not very relevant. Google something, open it and right-click. Copy will be greyed out.

Description

See this mozilla bug report https://bugzilla.mozilla.org/show_bug.cgi?id=1863246
It's actually caused by ublock Origin builtins - Badware risks

If you disable that builtin default filter, you solve this context menu copy greyed out behaviour.

quote of the issue:

I can reproduce this reliably by googling something, opening a result and without switching focus, right-clicking. Firefox 121.0 (64-bit) on linux Mint

Can confirm that disabling ublock origin fixes it
Can confirm that the addon https://addons.mozilla.org/en-US/firefox/addon/absolute-enable-right-click/ fixes it
Can confirm switching focus fixes it

I've narrowed it down to ublock origin -> Settings -> Build-ins -> Badware Risks

So I think it's not a Firefox issue but probably an uBlock Origin one. I'll report if I experience it again with those filters disabled.
