I'm not sure what you mean by -current. From what you posted: > OpenBSD 6.1-beta (GENERIC.MP) #7: Sat Mar 11 18:32:03 MST 2017 > dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP You forgot to tell the firefox version package. Here is what I have: OpenBSD 6.1-beta (GENERIC.MP) #214: Mon Mar 6 15:56:51 MST 2017 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP firefox-51.0p0 I have no single issue with firefox in my browsing. I still have some suprise to see that my favorite mirror is many days behind snapshots from the time point of view. Maintenance, perhaps?
