1. I know that bug team has had troubles recreating, but from the Firefox debugger, it's pretty clear that Facebook is detecting ad blocking and taking overt action to disguise an ad. I don't know enough about FB coding to understand what they are doing, but it's clear it is detecting AdBlocking, with or with ABP on, that is, ONLY with AdGuard and AdGuardExtra on, neither of which are catching the posted ad. Adding 2 screen shots with Firefox Debugger on, one with ABP+AdGuard+AdGuardExtra and one with ABP turned off for FB. Firefox 121.0.1; MacOS 12.7.2 Monterey; ABP 3.22.1, AdGuard Browser extension: Version 4.2.241 TSWebExtension v1.0.5 TSUrlFilter v2.2.8 Scriptlets v1.9.101 ExtendedCss v2.0.56 (All Default filters turned on) AdGuardExtra 1.0.571
