Silverlight on Catalina

Hi, I was using Firefox ESR 52 with Silverlight on Mojave, it worked fine until I updated to Catalina yesterday and Silverlight disappeared in my system and I can't install it back anymore.


I just want to know that if Silverlight is not supported anymore in Catalina?

Any method to install it back without reverse the OS to older version?

Well, there's Dayforce, which Trader's Joe's, at least, still uses. Dayforce is the payroll program that company uses. Since Silverlight has never been updated for Mac since v. 1.0, it's pretty safe to say that Mac users are locked out of using their company's payroll program, when of course all their PC users can.

Reminiscent of the early days of the internet where companies built their websites that would only work on Microsoft browsers. That’s how they killed browsers like Netscape. Silverlight is, of course, a proprietary framework completely controlled by Microsoft and they have already announced the end of Silverlight support for even Windows browsers. Silverlight is no longer supported on any browser for macOS and Macs. Read the link provided above by @dialabrain.

Have you considered IETab in Chrome? They previously relied on a user's version of iexplore.exe (which obviously would only work on Windows) but now they're doing some kind of cloud-based virtualization which seems to work like a charm on Mojave. This must be a recent development because some of the documentation on their website still says the extension doesn't work on Mac or Linux but...it does. No reason to think a virtualization-based solution wouldn't work in Catalina too. Give it a shot, certainly easier than a VMWare or Virtual-box based solution.

as far as I understand it's a thin remote client in a browser connected to cloud VMs so it's not going to be fast and the latency will be higher than running a VM on your own machine. You have to decide whether installing windows on virtualbox on your Mac just to run silverlight and all the attendant headaches that entails (obtaining a windows license, configuring your own VM, etc.) is preferable. I've done it both ways and I prefer IETab. YMMV.
