I’ve noticed the same issue with Synology releases on that page for many months with Firefox and Safari.
Looking at the inspector, I can see that the checksum is completely missing from the HTML of the page for various releases. And it happens even with content blockers completely disabled. So it seems to be a server issue rather than a client issue.
Looks like the checksums are now displaying when you click on “Show Checksums” and then on “Choose Distribution” - which is great.
The trouble is you can’t select the checksum value to copy it, as it seems to be part of the download link - clicking on the value starts the download, and doesn’t give you the option to select it (at least when using Chrome and Edge).
So a step in the right direction… but if anyone is seeing this, it would be nice if you could just double-click on the checksum value to select it (and then copy it and paste it in to whatever tool you use to verify checksums).
Thanks,
Nathan
P.S. I did find that if you put your mouse in just the right spot on the right-hand side of the value, you can click, hold, and drag and manage to select the checksum. So there is a work-around, but supporting a double-click on the value would still be nice.
