Firefox keeps failing to verify certain apps

I submitted this question to Stack Overflow almost three months ago and they never helped me so I decided to submit the question here.

Here's the problem. I get a message that pops up that says, "one or more extensions cannot be verified and have been disabled". I know a temporary fix to get these apps working again but the apps always break after so much time. What I do is go in my extensions for my Firefox profile (which is a JSON file) and I use Wordpad to change all the instances of appDisabled": true to appDisabled": false. I also change all the instances of signedState":-1 to signedState":2. The problem is that it keeps changing the false back to true and the 2's back to -1's. I am using Firefox version 56.0.2. Is there any permanent fix that can keep these changes under the current version that I am using? I am getting sick and tired of having to make these changes every day. Also, a couple of key add-ons that I use which are Classic Theme Restorer and unblock Origin keep getting disabling from this issue. I value these add-ons and I would love it if you knew any command prompt that I could put into Wordpad that would make Firefox stop trying to verify add-ons or whatever it does that causes Firefox to disable the add-ons. I welcome any other fix as well. I do want to keep my current version of Firefox and I know the Greasemonkey I use wouldn't work on later versions.

appDisabled":true

...
signedState":-1

When appDisabled is true and signedState switches to -1, I get the message saying, "one or more extensions cannot be verified." It also disables the incompatible apps.

What I have tried:

I already tried using Wordpad to change all instances of appDisabled": true to false and signedState":-1 to 2. It would work for a while and then everything reverted back to how it was.
