I've tested Vanadium, Firefox, Safari, Chrome, Edge, Brave - all of them on either Android or macOS and Orion version 0.99.128.2.1-beta is the only browser that consitently can't handle Bitwarden's Autofill option.
It'll only work when the extension is reloaded and then it'll break within 10 minutes. I'm using the recommened extension from Orion's Popular Extension page.
When using Autofill
Unable to autofill the selected item on this page. Copy and paste the information instead.
One can only manually reload the extension and it'll work. This is not a Bitwarden problem, it is Orion as it's the ony browser currentky with this issue
0.99.128.2.1-beta
