One note for anyone experiencing this issue: you can downgrade to an older version of the extension that still appears to work properly in Orion. Version “2024.1.1” has been verified to work. Visit the GitHub page for Bitwarden’s client apps, and navigate to that release:
https://github.com/bitwarden/clients/releases/tag/browser-v2024.1.1
Once there, expand the “assets” button, download the Firefox version of the extension, which is a Zip file. Once downloaded, rename the file from “.zip” to “.xpi.” Then, go into Orion’s extensions pane and tap the plus sign on the bottom left of the screen, select the XPI file, and then install. Everything should work from that point onward.
Ideally, things would work with the latest and greatest, but this will have to do for now.
