Firefox and not signed addon - how to bypass the error.
Firefox 52.5.3. I would like to ask how to make possible of using not signed addon. The problem is I am using some addon which is no longer in development state, and author is not interesting on fixing exist bugs in it. It is signed so I can install it on my profile without any issue. I have corrected few problems on my own and for my personal use - the problem is the addon is no longer seen as signed. So Firefox persitently disable this addon at start.
I have found somewhere such solution: - if addon was signed before modification and was installed under given profile then it is enough to change in extensions.json entry from "signedState":2 to "signedState":1. I can admit that this make the addon work till the next day, then i need to modify extensions.json once again, and have working addon till next day. And so on, so on. Can I somehow force Firefox to use this addon without any limitation?

Note: Windows users should download the ActiveX for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).
Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the ActiveX.

This will disable add-on signature enforcement; Firefox ESR version only. Enter about:config into your Firefox address bar Click the I Accept the Risk button Find xpinstall.signatures.required in the list Right click the preference Select Toggle until the value is false https://support.mozilla.org/en-US/kb/add-on-signing-in-firefox
"xpinstall.signatures.required" has been left as a compatibility solution, and i am not quite sure if it will still work. But even if that work it will disable signature enforcement on every addon, and this is not quite what i need. I only need to lower the security for one specific addon. For example the method with "signedState":1 is working for few hours already, but I know it is still time limited (intentional or bug), and after next hours Firefox will finally inform me that addon was disabled. Maybe some settings which disable this timer? Or extend this timer somehow? Or is it a way to sign the addon without publishing it to community? I have generated proper CRC for all modified files but I can't bypass the same for main file in addon due to missing signature file.

Signing the legacy addon is not possible. You can only sign webextensions (with or without publishing).
So it seems that there is no good solution, i am not interested in disabling signing enforcement for all addons, nor using nightly or development edition of FF. Total fail if You ask me.
Why aren't you using the current ESR release (52.7.2)?
If you have set xpinstall.signatures.required to false then Firefox should allow you to install unsigned extensions. In case of issues with signing it normally helps to delete extensions.json (and possibly addons.json) to reset the extensions registry.

Without the reason, just not making updates too frequently. I have grown over the idea that each update is better than previous version. Now I rather think that "better is the worst enemy of good". It is from my experiences using different kind of software. Besides this subject has no meaning for my main question.

And how good is the Mozilla verification process of addons? How can I be so sure that some addon won't be able to inject other, not signed addon?
I just don't want to disable signing enforcement for all addons, only for one specific, and legacy, where I fixed some bugs and use it for my own needs. Just when original author decided to stop playing with this addon, and do more interesting things. Nevermind, i don't expect more solutions for my question now.

Define "solved" firstly. In my opinion, there is no solution here. Workarounded (worse or better, no matter), but no "Solved". I don't see "workarounded" button anywhere.
