Firefox-based browsers not affected.

Hmm I opened linkedin in Firefox and ublock origin showed it blocked 4 items... then switched away and back and the counter was up to 12.

Is that enough blocking, I wonder?

Firefox uses randomised IDs for installed extensions, so the method highlighted won't work on Firefox. That's not to say they aren't trying other methods on Firefox.

Attack surface is narrower on Firefox. WebExtensions without DOM-visible traces cannot be detected.
