There's another way to trigger this:

1) Open Windows Narrator (NVDA may also work)
2) Open Firefox Nightly
3) Open the form select test case
4) alt-tab away from the window and back to get narration working
5) Tab to the test case select element (make sure Narrator announced the selection)
6) press alt down arrow to open the drop down popup
7) press alt up arrow to hide the drop down popup
8) use down or up arrow to navigate through select options

result: No narration occurs other than key input announcements.

This sounds like a variation on bug 1309271 to me.

I split this bug out from bug 1309271 to isolate issues specific to electrolysis in bug 1309271 . This bug reproduces in non-e10s as well, and apparently has been around for a while.

Hey Tracy, please confirm you can reproduce this on Windows w/e10s and non-e10s, and if so then please search for a regression range in non-e10s.

Narrator has an odd delay sometimes in announcing content. I retested and and found that if I sit on the select for a few seconds, the announcement will finally happen. This is with non-e10s, need to test e10s.
