The Copy URL extension was intermittently failing to copy anything, and
its notification looked oversized with no icon. Several distinct problems:
- The MV3 service worker was pinned to stale cached code. Chromium caches
the worker script for a --load-extension command-line extension and does
NOT re-register it when the file changes in place — not on restart, not on
a manifest version bump, not even after a clean shutdown. So updated code
never took effect: the old worker kept calling chrome.scripting.executeScript,
which throws once the scripting permission is gone, and the copy silently
failed. Renaming the worker to a versioned filename (background-2.js) is a
new script URL, which forces a fresh registration for everyone — new
installs and existing installs alike. Rename it again on any future worker
change (see the note at the top of background-2.js).
- Clipboard writes now go through an offscreen document (MV3's sanctioned
path) using a textarea + execCommand('copy'), replacing executeScript +
navigator.clipboard. This works on chrome:// pages and needs no scripting
permission. execCommand is used deliberately: navigator.clipboard.writeText
rejects in an unfocused offscreen document.
- Add a toolbar action (chrome.action.onClicked) so the extension is
clickable, not keyboard-only — it was greyed out in the extensions menu
with nothing to invoke.
- Slim the "URL copied" notification: lead the summary with a glyph so the
omarchy notification shell collapses it to a single-line toast with an
icon, instead of an oversized card with a blank icon slot.
- Guard the Quattro shortcut-repair migration: it edits Chromium Preferences
to move the Alt+Shift+L binding to the new extension id, but a running
browser rewrites Preferences on exit and reverts the edit. Prompt (via gum)
to close the browser first, only when a browser is running and there is
actually a stale binding to repair.
