Implementing features from Mercury

[ThousandDemonDaggers]

What feature would you like to see?

Since it seems that Mercury adds some patches that Zen Browser maybe hasn't implemented yet, wouldn't be a good idea to implement them? Also, Mercury doesn't seem to be updated regularly anymore.

List of patches included in Mercury

• Compiler modifications include AVX, AES, LTO and PGO.
• Disable all telemetry and reporting.
• Remove all debugging constructs and enable hardening by default.

Nope, this has been requested feature for a long time (https://connect.mozilla.org/t5/ideas/support-jpeg-xl/idi-p/18433)
