Agreed, it seems like there are two easy fix options here -- either:
 (A) Adjust the UA sniffing logic to check for **version 67 or lower** (and offer the old version in that case). This may be the most minimal adjustment that would help here. Though note that these Firefox versions are no longer supported anyway.[1]
...or:
 (B)  Just use the new format unconditionally.
