User Agent: Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170417065206

Steps to reproduce:

Type something in the search bar, select a suggestion so it is highlighted, optionally select some text in the search bar, quickly press backspace and then enter.

Actual results:

Backspace is ignored, the highlighted suggestion is searched.

Expected results:

Selected text or a character before the cursor is deleted, the corrected query is searched.
When I tried to reproduce this issue by pressing backspace, selected text or a character before the cursor is deleted from search bar, the edited query is searched and got proper result in latest Nightly.
BROWSER: Firefox nightly 55.0a1/64-bit/ Build ID:20170424030211
OS: Windows 10.0/64-bit

Need more information to reproduce:
Does this happens in latest version of the browser?
Does it happens in private tab?
May be MAC OS is affected with this issue. Will be good to have a test-case regarding this issue to reproduce further!!

Selected text may appear deleted for a moment, but then it is back after pressing enter.

You have to press enter immediately after backspace: the faster it is, the more chance of reproduce.
I believe this is a race condition, try to do it in a slow virtual machine.

I've checked in Nightly, it is reproducible. Nightly 55.0a1/32-bit/20170424030211.
This is actually a regression, in version 50 it seems to work OK, in 51 it is broken.

I have tested this issue on Windows 10 x64 with the latest Firefox release (53.0) and the latest Nightly (55.0a1-20170426030329) and managed to reproduce it.
After typing anything in the search bar and pressing the down arrow in order to select a suggestion, if quickly pressing the backspace and the enter key afterwards, the backspace is ignored and the highlighted suggestion is searched.

I've performed a regression, here is the pushlog:

Taking in consideration the pushlog above, I think that Bug 1306639 seems the most possible candidate to have introduced the regression.
Marco can you please take a look at this?

Thank you.
Ever confirmed: true

The only possibility that's the cause, is that it's due to the change in the autocompletecontroller
other code is unrelated with the search bar.
Adding to our triage.

52 ESR is also affected.
Too late for 53, but we could still take a patch in 54.
I've found out that this bug is even more annoying than it seemed at the first glance: it happens not only immediately after backspace, but I can enter a whole new word after that, and if the suggestion didn't disappear at the moment I press Enter, the uncorrected query is searched.
Priority: -- → P3
Marked as backlog, marking fix-optional for 54.
