 ### Installation
 You can install the add-on from Mozilla add-ons (AMO): [Bypass Paywalls Clean](https://addons.mozilla.org/en-US/firefox/addon/bypass-paywalls-clean)\
+Latest add-on versions (2.4.8.0+) require a browser based on Firefox 86+ (else use the non-amo version below).\
 Or download and install the latest xpi-version from [GitLab](https://gitlab.com/magnolia1234/bypass-paywalls-firefox-clean/-/releases)\
 By default BPC has limited permissions, but you can opt-in to enable custom sites (and also clear cookies/block general paywall-scripts for non-listed sites).
