We only used two rules from the plugin which can both easily be replaced nowadays: - `mozilla/avoid-removeChild` is equal to the already active `unicorn/prefer-dom-node-remove` rule; please see [1] and [2]. - `mozilla/import-globals` is mostly obsolete nowadays ever since we removed the Firefox extension code from this repository and we eliminated most globals usage. The three remaining occurrences can be replaced with explicit `/* globals */` comments that we already use elsewhere, which overall is also more consistent.
