Starting with
Bug 1746462 you can use
mold linker for linking Mozilla Firefox on most linux distributions.
In order to use mold please update you mozconfig file as:
`````````````
ac_add_options --enable-linker=mold
`````````````
Please note that `ac_add_options --enable-linker` takes the path to the mold linker from your system.
If you encounter any sort of issues using it, please let us know.
