1838037 - Minify JS code in Firefox

Status: RESOLVED DUPLICATE of bug 1505119

(Firefox :: General, enhancement)

Description

[Marco Castelluccio [:marco]]

The size of JS files has a great effect on memory usage (and probably startup performance), especially for modules that are loaded in every content process.

We are already minifying JS files on Android, https://searchfox.org/mozilla-central/rev/b91e9bef5a6d6f7b549fbc9cba70cb4665ed3866/toolkit/moz.configure#924.

Should we do the same with Firefox JS files?

Note this becomes more and more important as the number of content processes increases.

I found in a memory regression investigation that just deleting the comments in my TranslationsChild.sys.mjs file reduced memory usage by 4,608 bytes per content process.

I don't think there is a need to keep two bugs open here
