Thank you very much for the report. I also could reproduce it.

I investigated this, it seems that the issue might be caused by Merino implementation for amo.
Even if I input nike and Nike and any query including upper cases on the urlbar, I could see the sponsored suggestion from the queries, but not amo. Just to be safe, I took a look at the suggestions data in UrlbarProviderQuickSuggest as well, but there were no suggestions for amo if the query includes upper case char.

I have seen the Merino code, it seems that amo provider does not normalize the query, so, we should do it as the same as other providers?

Yes that looks right to me Daisuke. I've asked Michelle about this too on Slack. I think the amo provider should normalize the query string like the adm provider does.

This has been fixed on Merino: https://github.com/mozilla-services/merino-py/pull/311

It can be verified using the preconditions in comment 0 and also setting browser.urlbar.quicksuggest.remoteSettings.enabled to false to turn off remote settings suggestions.

Addon suggestions from remote settings don't have this problem, and that can be verified by setting browser.urlbar.quicksuggest.remoteSettings.enabled back to true and browser.urlbar.quicksuggest.dataCollection.enabled to false to disable Merino.

The issue is verified fixed using the latest Fx 115.0b3 on Windows 10 and Ubuntu 20. The add-on suggestions are correctly triggered regardless of capitalization, from merino as well as RS.
