Im not sure if anyone else has noticed this, but in the new firefox update has anyone else experience the responsive features not working properly?
Yah Firefox 34 broke flex. Fun. There are some workarounds, just need to implement them this week.
Ok this wasn’t too bad a fix. Antimatter has been updated with the fix in it (as well as the getgrav.org site also).
If you have not changed Antimatter, or are using it as a base theme just update Antimatter with GPM.
If you have made modifications, you can see the changes made here:
