Starting [Thursday, April 18th], the original, Muon-based release of Brave (v0.27.3 or earlier) will be fully deprecated and you will no longer be able to use it to browse the Web. You will be notified of the change and encouraged to upgrade to the new, Chromium-based version of Brave.
We are extremely proud of the Muon build and appreciate the high level of support from users who still have it set as their default browser.
We understand that disabling the browser entirely may seem strong-handed and that many of our users may not agree with this decision; however, two primary reasons necessitate this change:
Security - The most important and heavily weighted factor in disallowing the use of Muon concerns security while browsing. We began depreciating and halting support for Muon last year as we rolled out Brave Core.
Given that we have not been pushing security or Chromium updates to the browser, the various filter lists for safe browsing, ad blocking, and general security patches are out of date, making you vulnerable while you browse. Important security issues like these will not be fixed in Muon and we believe it is unsafe to continue using it.
Resources - Keeping this code base up to date (both feature-wise and security-wise) is extremely time and resource intensive. The switch to the Chromium front end has allowed us to implement these updates in our new version in a fraction of the time it took on Muon. Given the complexity of these updates and the limited developer resources, maintaining two completely different (and large) code bases is not feasible.
Once the final update to Muon is pushed:
- A notification describing these changes will be displayed on the New Tab page when the browser launches.
- You will have 10 days to save, export or backup any open tabs/sessions you have in Muon.
- After the 10 days, the URL bar will be disabled and browsing in Muon will not be possible. Internal pages such as Brave Payments, Sync, bookmark manager can still be accessed after the 10-day limit however.
What happens to Brave's old version (Muon)?
Even after being disabled, Brave Muon will remain on your machine until it is uninstalled. This is because in order to import Muon data into Brave Core (using the built-in import tool), a Muon installation must be detected on your device.
No data stored in the old version of Brave (i.e. bookmarks, history, or wallet information) will be lost or overwritten. Any profile or browsing data will stay in the same place as it was stored before the update:
|Operating System||Profile Path|
Once your data is backed up or imported, you can uninstall Muon at any time:
- Windows - Uninstall Muon the way you would uninstall any other program using the Windows Add or Remove Programs tool. A warning prompt will notifiy you that this will remove Brave and any associated data.
- macOS - Find Muon in the “Applications” folder on your machine and select “Move to trash”. Note that this will not remove any associated browsing data for Muon. You must locate and trash the profile data folder (see above). Note that if you elected to keep the Muon icon in the dock, it may remain even after uninstall. Simply right-click and select Options → Remove from dock from the context menu.
