1651189 - Activating address bar when a new typed domain is still loading only selects the trailing slash

Status: NEW

(Firefox :: Address Bar, defect, P3)

Description

[Alexander]

Attachment: screencap.gif

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:79.0) Gecko/20100101 Firefox/79.0

Steps to reproduce:

Type an address I've visited before, such as bogleheads.org/, into location bar. Note trailing slash. Problem also happens if you enter the full URL, e.g. https://www.bogleheads.org/. Hit Enter. Then immediately hit Cmd-L before the page has fully loaded.

Actual results:

This will select only the "/" part of the URL.

Expected results:

The whole URL should have been selected.

I discovered this because sometimes I want to open a URL that I've visited recently and also copy its URL so I can paste it into a Hacker News comment or whatever. The easiest way is to autocomplete it, then select the URL. Often I end up with just "/" on the clipboard due to this bug.

It looks like a race condition between autofill and select all

It seems that mozregression pointed out Bug 1601052 - Wait for both TabSelect and urlbar focus changes from the tab switcher. r=dao for causing this regression.

yeah, just too many things happen at once in this case

This is not limited to race conditions with Ctrl+L, with a bad internet connection this state can persist.

Comment 7

[Kestrel]

STR:

1. Use a very slow/limited/blocked proxy (eg tor).
2. Type a domain and press enter (eg soundcloud.com).
3. While page is stuck loading, click in the address bar.

Only the trailing slash is selected, copying and pasting ouputs "/".

Does not happen when including https:// for unvisited sites.
