     * CVE-2020-12395 (bmo#1595886, bmo#1611482, bmo#1614704, bmo#1624098,

   - Since firefox-gcc8 now has disabled autoreqprov for firefox-libstdc++6
     and firefox-libgcc_s1, those packages don't provide some capabilities,
     we have to disable AutoReqProv in MozillaFirefox too so they're not
     added as automatic requirements. (bsc#1162828)
