Adds browser.taskbar.dockProgress.enabled (default: true) to allow disabling the macOS dock download progress indicator. When disabled, the dock icon is not replaced with a custom NSView during downloads, preserving the macOS Tahoe Clear/Dark/Tinted icon styling. Root cause: Firefox's nsMacDockSupport sets NSDockTile.contentView to a static bitmap + progress bar overlay, replacing the OS-managed icon that macOS applies Clear styling to. After download completes, macOS does not re-apply the styling. Upstream: https://bugzilla.mozilla.org/show_bug.cgi?id=1997246 Closes zen-browser#12676

Summary
Adds a
browser.taskbar.dockProgress.enabledpreference (default:true) that gates the macOS dock download progress indicator inDownloadsTaskbar.sys.mjs. When set tofalse, the dock icon is not replaced with a customNSViewduring downloads, preserving the macOS Tahoe Clear/Dark/Tinted icon styling.Root cause: Firefox's
nsMacDockSupportsetsNSDockTile.contentViewto a static bitmap + progress bar overlay, replacing the OS-managed icon that macOS applies icon styling to. After the download completes, macOS does not re-apply the styling. There is no existing preference to control this behaviour.Upstream: Firefox Bug 1997246
Closes #12676
Implementation
Single patch file:
src/browser/components/downloads/DownloadsTaskbar-sys-mjs.patchThe patch inserts a
Services.prefs.getBoolPref()check before thethis.#taskbarProgresses.add(gInterfaces.macTaskbarProgress)call in the macOS branch ofregisterIndicator(). Default istrue(no behaviour change). Users who want to preserve their Tahoe icon style setbrowser.taskbar.dockProgress.enabledtofalseinabout:config.Testing
I have verified this fix works by binary-patching the equivalent code in
omni.jaon Zen 1.19.3b / macOS Tahoe. With the preference disabled:I have not set up the full Zen build environment to run
surfer import, so I'd appreciate a maintainer verifying the patch applies cleanly.Notes
