A user reported (and I have confirmed) that when using Firefox within a Mac environment the vertical scroll bar for the Slicer visualization is not present.
I think he means the Mac preferences rather than Firefox.I tried it - made no difference to me though...
Ok, I have found the options within the Mac Preferences. Mine were already set to those recommended - so no change. Anomaly still exists.
I’ve got response from the Product Team.
We do not support Mozilla on Mac. we only support safari. https://powerbi.microsoft.com/en-us/documentation/powerbi-service-browser-support/ We use external library for scrollbar which is not supported on firefox in chrome.
