Comment 11 for bug 1908082

@Olivier Tilloy, ironically, I'm now seeing the same behavior in version 90. I don't remember if the performance behaved the same way in 89 or not, but maybe? At any rate, performance of Ubuntu's builds has vastly improved, even if it's still not quite on the same level as Chrome. I haven't re-tested non-Ubuntu Firefox yet either.

Also, I'm on 20.04, which might be making a difference.
