Thanks for reply.
I did rebranding by creating folder name "Esymed" Under branding folder. I updated .moconfig file as below
ac_add_options --enable-official-branding
export MC_OFFICIAL=1
export MOZILLA_OFFICIAL=1
# Only enable the internal updater if you supply automatic update infrastructure
# and have configured the relevant preferences in your branding!
ac_add_options --enable-update-channel=release
ac_add_options --disable-updater
ac_add_options --disable-precompiled-startupcache
ac_add_options --enable-jemalloc
ac_add_options --enable-strip
ac_add_options --disable-parental-controls
ac_add_options --disable-accessibility
ac_add_options --disable-gamepad
ac_add_options --disable-eme
ac_add_options --enable-webrtc
ac_add_options --enable-av1
ac_add_options --with-branding=palemoon/branding/esymed
After enabling webrtc it is failing build every time. I commented the code as well but still fails (Platform/old-configure.in). I am using the release branch as suggested.
It seems like customization is not a easy task
Please suggest what I am missing.
