 Replying to [comment:38 acat]:
 > The asm.js caching was removed in
 https://bugzilla.mozilla.org/show_bug.cgi?id=1520931. Should we revisit
 this and try to enable asm.js for esr68? We should be able to remove
 `Services.qms.clear()` in torbutton and revert #31396.

 Sounds good. Please do, if you want. How does it work then, though, if you
 have PBM disabled? Is everything happening on the fly, in memory, or...?
 We should investigate the FPI concerns here, too. See: comment:32
