Well, it does what it says, if that's what you mean by "works". But I don't think my grandpa is going to be happy with the results.

Here's NYT with that firefox "zoom text only" enabled: https://i.imgur.com/zp7pDW3.png

See the chopped "rld" on the left? That's the link to the "World" section. To the left of that off the screen should be the "U.S." section. But there's no horizontal scroll bar or any way to get to it, or any way to even know it exists. Categories spill off the right too, and you can't get to those either. This anti-feature, in the name of accessibility has actually just made things worse.

For reference, here's the totally sensible result if you just don't enable "zoom text only": https://i.imgur.com/Kkd5aOu.png
