Legacy Browser Support extension for Windows

Legacy Browser Support release notes

See the changelog below for the Legacy Browser Support (LBS) version history. We recommend you are using the latest version of the Legacy Browser Support MSI and Chrome extension.

Here's a list of the new features with each LBS release:

5.9

  1. Added new interoperability functions to the LBS extension. These are in anticipation for when Legacy Browser Support's functionality is incorporated into Chrome Browser in a future release. For more information, see "Legacy browser support planned to be incorporated into Chrome 75" in the Chrome Enterprise Release Notes.

5.5

  1. Fixed an issue with the AlternativeBrowserArguments and ChromeArguments policies not being applied in LBS.
  2. Fixed an issue with Internet Explorer site lists where whitespace around domain names was not properly trimmed.

5.4

  1. More precise rules in the URL lists make managing multiple sites hosted on the same domain simpler. Specifically, the more precise URL entries in any list are preferred over less precise ones.
  2. Improves support for automatically generated Internet Explorer site lists.
  3. Reminder: If you deploy the Legacy Browser Support MSI manually, make sure to download and deploy the newest version to avoid the MSI being out of date with the latest Chrome extension version.
