Are XType Keys still supported under Firefox?

I’m using UI.Vision RPA under Firefox 99 (64-bit). I’m trying to make a makro, which will use keyboard at some stages. However it seems like XType is not working. Generic type command works, but it can send only text. To send for example Tab or Enter, I need XType, but I can’t make it work. Here is MVE:

  "Name": "Keys",
  "CreationDate": "2022-5-2",
  "Commands": [
      "Command": "open",
      "Target": "",
      "Value": "",
      "Description": ""
      "Command": "XType",
      "Target": "${KEY_TAB}",
      "Value": "",
      "Description": ""

I can supply any key under ${…}, it makes nothing. I have RealUser XModule installed, version 1.0.31. What’s more do I need to make it work?

All works fine. I think the issue is that you do not set the focus on the website. You can use XCLICK or simply “BringBrowserToForeground” for this. See this video:

Thank you, it was the focus. I thought it is set by default. Now almost everything works fine. I only have a trouble with ${KEY_ENTER} in file upload window. Is this issue still open? Chrome update disabled the file upload feature? {"code":-32000,"message":"Not allowed"} - #2 by admin

I was able to make it with workaround (slight modified as I work in dual monitor mode, and image recognition has troubles with accuracy, so I hard set location to click), however it would be nice to have it in more elegant way.

File upload works fine meanwhile, see Chrome update disabled the file upload feature? {"code":-32000,"message":"Not allowed"} - #17 by admin

But 7.0.9 has an issue: Error ipcPromise on load pictures to a website - #2 by admin

But both posts are for Chrome, Firefox is not affected by these.

Are you sure? Any time I try it gives me error:
Setting file path fo file inputs is not supported by Firefox extension api yet

Do you mean type | name=upfile | C:\\some_path\\test.txt or other method?
