Today, 4th of May 2019 my Firefox suddenly after startup give me message that all of my add-ons has been disabled during non-valid certificate and suggested to make replacement for them. After check, I lost all of my add-ons and NONE of available ones on your web page was able to download, giving me "Download failed. Please check your connection." error message. Looks like this is an issue that affect all FF users all around the world. I am using 66.0.3 64-bit version on Ubuntu 18.04.2 version. I hope this issue will be solved asap. Regards,
