1653697 - Can't quickly type "about:" in address bar because autocomplete suggestions overwrite typed text

Status: RESOLVED DUPLICATE of bug 1653436

(Firefox :: Address Bar, defect)

Description

[Chris Peterson [:cpeterson]]

[Tracking Requested - why for this release]:

This bug is a regression in Fx80 Nightly.

I have trouble typing about:config into my Nightly address bar. If I type a, b, o, u, t quickly, the b disappears and I get aout instead of about. If I pause about half-a-second or longer between key presses, I can then type about:config successfully.

The address bar's autocomplete suggestions for domains like "app.slack.com" or "auth.mozilla.auth0.com" overwrite the text I am typing. I don't see this in a clean user profile that doesn't have a long browsing history for autocomplete suggestions.

Harry, I bisected this regression to the following pushlog, which includes your autocomplete changes from bug 1645521 and bug 1645324:

Thanks for the bisection! I'm pretty sure this one was caused by bug 1648468 which is also in that stack.
