approved add-ons continue to be disabled

I have used the following add-ons for a couple of years without problem.

 Lastpass 
 FEBE

I am running version 54.0 32 bit version of Firefox. Firefox continuously disables both add-ons as not compatible with the current version of Firefox. Despite removing and reinstalling both addons from addons.mozilla.com numerous times, the browser continues to disable them. It is my assumption that addons available from the site have been approved and are compatible with Firefox. These are the only two addons that are continuously disabled. A screenshot of my installed addons is enclosed. It becomes aggravating because I use Lastpass and FEBE daily. Your assistance with resolving this would be greatly appreciated. Please let me know if there are questions or additional information is needed. Thank you.

Firefox periodically performs a check on the Add-ons website to make sure that all extensions are still signed correctly. If this check fails then Firefox will disable the extension. So make sure that this check isn't blocked by your security software or otherwise.

Thank you the information. I assumed that addons are signed if they are available on addons.mozilla.com. Is this incorrect? Also, what ports or services need to be available outside of internet access for the check to function? Thank you.
