Citrix Reciever issue

[okkehel]

why is vivaldi not working properly with citrix reciever?

@okkehel According to this article
https://support.citrix.com/article/CTX200889
the Citrix Receiver client uses a NPAPI (Netscape) browser plugin that's no longer supported by Chrome or Vivaldi. Unfortunately, the workaround to reenable NPAPI plugins is no longer possible because the NPAPI code has been completely removed from the browser.

Thanks for that one but it is confusing. I have to use Citrix Reciever on two different applications/websites. One site is downloading a file with the extension .ica. Double click on that file and Citrix Reciever starts (in Vivaldi, in Firefox it starts automaticly).The other site downloads a file with the extension .aspx. Double click on that one: nothing happens. In Firefox it starts Citrix Reciever however. Rename that .aspx file in .ica and after double click it opens Citrix Reciever. So Vivaldi works with Citrix Reciever but on a strange way.

@okkehel My apologies for not explaining this better. Citrix Receiver has a "helper plugin" to launch the client from a web browser. It uses a "legacy" plugin type that, until recently, was supported by all browsers... that is until Chrome (and related browsers) transitioned to a new plugin technology. Now, on macOS, the only major browsers that support these "legacy" NPAPI plugins are Firefox and Safari.

Citrix still has (apparently) not updated their software to integrate with Chrome and other Chromium-based browsers like Vivaldi.

I'm using latest Vivaldi snapshot and Citrix .ica files are running automatically for me.
Edit: Sorry, I miswatched that I'm replying on Mac forum.

@enc0re My Citrix knowledge is limited and it's been a while since I've even had to use their client.

On https://www.citrix.com/products/receiver/ they have a tip for:
Google Chrome asks me to download and install Citrix Receiver each time I access my apps. What's happening?

Did you have to do anything special to get this working with Vivaldi?

Thanks!

@xyzzy Nothing. I just installed Citrix plugin, have to check which version and that's it. But I have to say that it was on my company pc, and windows on that is full of garbage.
