BleachBit 4.4.1 beta

Please test BleachBit 4.4.1 beta, which will become the 4.4.2 major release.


November 13, 2021: BleachBit 4.4.2 has been released.


For a list of changes see the commit log and GitHub bug tracker.


Please test the application in general with special attention to the following tests.

These tests are for both Windows and Linux:

  • On the main BleachBit window, verify that using the mouse on the left vertical slider (next to the checkboxes) allows you to scroll to the bottom. To scoll, try both left clicking and the mouse wheel (issue 1179).
  • Verify that right clicking a cleaning option works using the text described at the top of issue 1201.
  • Open Brave, Chromium, Google Chrome, Microsoft Edge, or Opera, visit a site, and create a site setting. To see site settings in Google Chrome, click the lock icon to the left of the page address. Then in BleachBit, choose the new site preferences option, and then verify in the browser that the settings were reset (issue 1236).


  • Test installer for Ubuntu
  • Test installer for Debian 11


  • In the Windows control panel, uninstall BleachBit. Delete the folder %localappdata%\fontconfig, if it exists. Install the new installer, and after it is done and before starting the application, verify the folder exists. Delete the folder and start the application. Verify there is a splash screen that appears while the folder is being created, which usually last roughly 20 to 60 seconds (issue 1263). Restart the application, and verify the startup is much faster because it used the font cache from the previous start.
  • In the Windows control panel, uninstall BleachBit. Download the installer, and run it like BleachBit-4.4.1-setup.exe /S /NoDesktopShortcut /allusers. Verify the installation takes place silently without user interaction or user feedback. Verify no shortcut is placed on the desktop (issue 437). Then, repeat this test but use different capitalization and order for /S /NoDesktopShortcut /allusers and it should still work. For example, use /allusers /nodesktopshortcut /S.
  • After installation, verify in the Windows start menu that there is not a shortcut to the BleachBit uninstaller (issue 1244).
  • Click the application menu (top left corner) and choose the option to shred a folder. Verify the folder selection dialog allows you to paste the folder name (issue 1175). Also, verify the deletion is successful. (Use only on a folder that is safe to destroy.)
  • In BleachBit preferences, enable the Winapp2.ini option. Verify that among the list of cleaners there are section groups named Internet Explorer, Vivaldi, and Brave (assuming those are installed) instead of numeric codes 3001, 3033, and 3034.
  • Verify the Winapp2.ini exclusion is honored as described at the top of issue 1247. Create a file called update-config.json, if it does not aleady exist, in a folder matching the pattern %CommonAppData%\Mozilla\updates\*\. The contents do not matter, and the file can be empty. Run preview or clean for option Firefox/Mozilla: Updates, and verify the file is not matched.
  • Under a folder matching the pattern %LocalAppData%\Microsoft\Edge*\User Data\*, create files called LOG, LOG.old, and ALOG. The contents do not matter, and they can be empty. Enable the Winapp2.ini option in the preferences, and run the cleaner called Microsoft Edge. Verify the first two files are found by either preview or delete, but the third file should not match (issue 982).
  • Shred a file using the Windows shell integration as described at the top of issue 1227.


See the downloads folder. For Linux, there are .deb and .rpm packages. For Windows, there is a digitally signed installer and portable package.
