Phew, I thought it was just me.
On Mac OS 10.11.6 (El Capitan), older Macbook Pro.
I am a die-hard Firefox user, forums have not worked in Firefox for several days.
Tried Safari, everything works there. Currently using Safari to make this post. Not a fan of Safari.
Tried Chrome, didn't work at first, cleared cache on Harvey's recommendation, worked after that. Not a fan of Chrome.
Have cleared cache several times on Firefox, plus just did the manual cache cleaning as per Harv's link. Still no go on FF.
Don't surf on my phone, can't help there.
SBR over and out.
