I'm experiencing pretty serious problems with this update. Once upgraded I start firefox again and some data would load but it would quickly seem to then fail to load almost anything, just a white page with no errors usually. Gmail specifically would show a corrupted content error which I've lost because I had to downgrade to post this update. :)
This was with an older firefox profile, but it also has not caused a problem in years and years.
Works for me. Looks like the secrets patch is back too, thanks!
Tested this build for my limited usage (import distros, koan guests, modify profiles, etc) and appears to be working fine.
Tested and working for us.
After updating NSS my issue is gone as well.
