I’m still running my DS1812+, she’s purring along with no signs of distress. 😅 I have another DS1515+ that I recently added and the difference in speed/responsiveness in the DSM OS is night and day. So the older DS1812+ is now mostly for long term storage.

Agreed, I’ve never come across a site that was broken because of Firefox. Usually the culprit is adblock being too good at blocking, so just toggle it off and refresh and page loads just fine.
