Uninstall LibreWolf on Mac

Save any LibreWolf bookmarks and the profile before removing the browser; ~/.librewolf can also hold an overrides file. The September 17, 2026 record covers the Homebrew cask.

Quit and remove the app

Quit LibreWolf, then move LibreWolf.app to Trash. Keep the profile until you have opened the exported data in another browser. The official page has more product information.

Review the app’s data

The cask names ~/.librewolf and ~/Library/Application Support/LibreWolf as data, plus LibreWolf cache and preferences. The first two may contain profile settings or overrides; inspect both rather than deleting them as cache.

If you installed it with Homebrew

The Homebrew cask has its own --zap list. brew uninstall --cask librewolf removes the cask without that list; brew uninstall --cask --zap librewolf also acts on its listed data without consulting Mole’s checkboxes. Its zap list includes both profile roots, so review them before using zap. Mole skips Homebrew zap for browser casks and uses its own selected-remnant path.

brew uninstall --cask librewolf

Check the result

These commands inspect the running process and one relevant location. They do not remove anything:

pgrep -il "LibreWolf"
ls -ld "$HOME/.librewolf"

No pgrep match means no process with that name is running; a match needs identification before quitting anything. A listed path still exists, while an ls “No such file” error means only that exact path is absent. A permission error is inconclusive.

What Mole lists

Mole leaves browser profile rows unselected. Exact LibreWolf cache and preference rows can be selected by default; it does not claim other Firefox profiles.

What this test covered

The test used the Homebrew cask. The September 17, 2026 sample retained the LibreWolf profile under the browser-data policy. The record does not prove that a custom overrides file, another profile, or signed-in sync was exercised.
