Clarified that the Studies fix applies only to Desktop users of Firefox distributed by Mozilla.We’re tracking this issue on Bugzilla in bug 1549078. We’re aware that some users are reporting that their extensions remain disabled with both studies active.Clarified that the study may appear in either the Active studies or Completed studies of “about:studies” (May 4, 12:10 EDT).Updated the post to clarify that deleting extensions can result in data loss, and should not be used to attempt a fix.They’ll be re-enabled as more updates become available. Temporarily disabled commenting on this post given volume and duplication.We’ll let you know when further updates are available that we recommend, and appreciate your patience.

These are not recommended as they may conflict with fixes we are deploying.

For everyone else, we are working to ship a more permanent solution. If it’s possible for you to receive the hotfix, you should get it by 6am EDT, 24 hours after it was first released. Rather than using work-arounds, which can lead to issues later on, we strongly recommend that you continue to wait. Some users are reporting that they do not have the “hotfix-update-xpi-signing-intermediate-bug-1548973” study active in “about:studies”.More information about the remaining issues can be found by clicking on the links to the release notes above. There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061). A Firefox release has been pushed - version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR.
