Issue persists in private browsing without extensions

I have the same problem
Firefox Developer Edition 145.0b9 (64-bits)
Same in private browsing

Fine in Edge 142.0.3595.65 (64-bits)

[VILJkid]

Yes, facing the same issue in Firefox (both normal, and private), but running fine in Brave (both normal, and private).
No extensions installed in either of these.

Can confirm issue against Firefox 146.0.1 (64-bit) and Firefox Developer Edition 147.0b6 (64-bit)

Issue is not present in Chromium 143.0.7499.169 (64-bit)
Opera One(version: 126.0.5748.0)
or with Vivaldi 7.7.3851.66 (Official Build) (64-bit)

So this is clearly just an issue on Mozilla

[VILJkid]

Yes. I think this pattern leads to the Firefox browser.
I've opened an issue via their issue tracker.
webcompat/web-bugs#196226

It now work in Firefox Developer Edition 145.0b9 (64-bits)

[lll123github]

This is a bit odd behavior. 2 days ago I was getting the same ada query error, but now it's working fine.
I'll check this today and tomorrow and update the same over here.

[jakob1379]

Worked for me, just now
