+++ This bug was initially created as a clone of Bug #1751978 +++

Seen in 98.0a1 (2022-01-25) (64-bit), Win10

STR:

• Edit a contact in ("new") Address Book
• Fill First, Last, Email address
• Press Enter with focus in Email address input to trigger the default button (Save)
• Try to save the contact using keyboard only (!)

Actual results:

• Pressing Enter does nothing.
• Saving the contact via keyboard requires pressing Tab key as many as 32 (!) times.

Expected results:

• Pressing Enter from any input should trigger Save default button as it used to - that's how default buttons work in dialogs, and this is essentially still a modal dialog as Magnus correctly pointed out.
• In addition, explore restoring an access key for pressing Save button (well, that's another can of worms, just listed here for contextual completeness).

For keyboard depending users like the blind, this will be living hell, hence S2/P2.

For keyboard depending users like the blind, this will be living hell, hence S2/P2.

Update: Keyboard dependent users will have to press the Tab key as many as 32 (!) times starting from email field. I initially miscounted.

I think the fields should be within a <form> so that normal "submit" logic applies.

I have a patch underway for this and bug 1752051, if you haven't started yet.

Adding what I had. Working but some things to sort out wrt how "New Contact" works while editing. In the patch I would disable that while editing since it's rather confusing what one gets... but I saw one of your other patches might have taken care of this now.
We really should get bug 1562198 fixed. At the moment we kind of allow saving invalid values. Or not really, but the UI implies we would, e.g. an invalid email will "save" without warning, but will not really be saved.

Thanks for this. Confirm that both esc and enter work on Windows with 99 beta. And there is a prompt when cancelling if data has changed.
