ActiveX on Firefox

eea
eea

Dear Support,

We are using IE on Windows for our main application and using ActiveX script to print directly to the printer and this is working fine. Now, we need to migrate the application to Ubuntu desktop and use the Firefox as web browser instead of IE but the ActiveX script is not working from Firefox. What is the similar feature in Firefox for Activex?

There's not really an equivalent. It would really help to know what exactly your ActiveX script needs to do though.

What's available currently are Web Extensions APIs like:

https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/tabs/printPreview https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/tabs/saveAsPDF

If the use cases is persuasive enough, those API's can potentially be expanded.

Why does your application need to print directly to the printer? I think a more broadly compatible approach would be to serve PDFs to the browser for the user to print in their preferred way.
