Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

I searched, and all the internet results I find tell me to look in the settings:applications:mailto ddlb and select Yahoo. The problem is that it's not there.

There is a "use other" but there's no hint on how I'd tell it to open https://mail.yahoo.com.

How do I get it to open Yahoo mail?

This is on W11.
