2041228 - can no longer ctrl-a to jump to beginning of a line

Status: VERIFIED FIXED

(Firefox :: General, defect)

Description

[Martin Balfanz [:mbalfanz]]

Using ctrl-a to jump to the beginning of a line is broken. This is likely regressed by https://bugzilla.mozilla.org/show_bug.cgi?id=103422

It applies to the places like the Firefox URL bar, but also page contents. See https://bugzilla.mozilla.org/show_bug.cgi?id=2038973 for a video on Google Docs.

STR:

• type a really long URL into the URL bar, one that scrolls beyond the bars dimensions
• try using ctrl-a to jump to the beginning of the line

ER: cursor jumps to the beginning of the URL

AR: cursor jumps to the beginning of the visual area, not the very start of the URL

I'm seeing this behavior on MacOS. Haven't tested other operation systems.
