Just thought I'd confirm for anyone else in the same boat that restarting the browser resolved the issue for my website in question. To clarify, I installed Bitwarden via Popular Extensions and autofill was working for several other sites.
Bitwarden version: 2025.2.0
Orion version: Version 0.99.134-beta (WebKit 619.1.11.111.2)
Both latest at time of posting
Thanks again to @dino for the tip! I'll keep an eye out if this issue arises for other websites in the future.
