(edit) I'm seeing it now. I've got a 1s timeout to cancel the auto after the last change in selected text. I'll add a setting for you slowpokes

> 1. When highlighting text "too slowly" the tiled popup won't show. Time to select text and the popup to show should be longer. Is there a way to increase that?

I can't reproduce that bug. I assume you're using the Auto opening method? I've tried going super-slow and never had the popup fail to open.

Does it happen on all websites?

Could you be having a conflict with another add-on?

What OS / FF ver are you on?

If the problem persists, open an issue at the support site and I'll work through some troubleshooting with you.

> 2. In search fields, auto close the popup when start typing on (on-screen keyboard and regular) would be nice feature to have.

Again, I'm assuming you're using Auto AND you enabled popups on input elements? That seems like a reasonable option to add. Look for it in the next release.
