Quote:Mozilla has officially released Firefox 66.0.2 for the Windows, Mac, and Linux platforms with fixes for compatibility issues affecting Office 365, iCloud and IBM WebMail users, as well as to fix tab crashes impacting Windows 10 1809 users.
 
As detailed in Mozilla's release notes, the new Firefox release addresses "web compatibility issues with Office 365, iCloud and IBM WebMail caused by recent changes to the handling of keyboard events."

• For Office (bug 1538651, bug 1538652), we decided to add some wildcard domains. This is based on this comment, and initial conversations we had with Microsoft. It's probably the safest approach for us right now.
  
• For IBM Webmail (bug 1538317), this patch only includes the one known domain. The domain is mentioned in IBMs docs, so it's likely a generic endpoint for one of their shared cloud offerings. We're working on getting more information here, but for now, that's all we have. Given we can't really tell what else is behind that domain, using a wildcard here would be dangerous. We can iterate in the future.
  
• For iCloud (bug 1537913), Adam confirmed in that bug that this resolves the issue. iCloud always seems to hard-redirect to the www-subdomain for these documents, so I see no reason to use a wildcard here.
