I have this version of Firefox: 66.0.3 (64-bit) It updated and many of my add-ons will no longer work. I tried to download some new ones that will work but each add-on I try to download gives me this error: "Download failed. Please check your connection." My connection is fine. Is anyone else having this problem? Any suggestions as to how to fix it?

There was a Bug-A-Boo with a Certificate Expiration Date dealing with the Add-ons. There's a new FF Version with the main Fix, 66.0.4.

Mozilla Blog Post Update:
A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061).
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. More information about the remaining issues can be found by clicking on the links to the release notes above.

hi, this is/was caused by an unforeseen technical problem unfortunately (an expired certificate used in the process of verifying addon signatures).

a fix for this is already being rolled out - for details, please see: Add-ons disabled or fail to install on Firefox
