How to completely disable compatibility check

[AbrahamLinksys]

Hi, I'm trying to install Policeman 0.8. It worked fine in version 24.9 so it should work in 25.x. I want to force install it to see if it works, but I can't.

Here's what I've tried so far:
- Editing the minimum version in "install.rdf" in the .xpi
- Overriding the "general.useragent.override" and "general.useragent.override.addons.mozilla.org" to version 32
- Changing "extensions.lastPlatformVersion", "extensions.lastAppVersion", and "extensions.check-compatibility.app-version" to version 32.0.2
- Setting "extensions.checkCompatibility.25.0" to false

After all of this, I can install the addon, but I still get the message that it's incompatible with 25.0.2. How can I force disable check compatibility?

EDIT: Turns out setting the mininum version in the .xpi to 24.x doesn't work, it has to be 24.0.

For Pale Moon I use an old but good and still perfectly working firefox add-on to disable add-on compatibility check:
"Disable Add-on Compatibility Checks" (In the add-on manager it's named "checkCompatibilty" after install).
Add-on URL: https://addons.mozilla.org/firefox/addon/checkcompatibility/ - (be careful with disabling the compatibility check!)

And "24.x" cannot work, it has to be "24.*"

Disabling add-on compatibility checking is strongly discouraged!

If you are force-installing extensions that are marked incompatible (I assume updated for changes in later versions of Firefox) then you are likely going to break your browser functionality. Instead, you should check in that case if there is an older version of the extension that is marked compatible with Pale Moon's extension compat version (24.9) since that it the extension compatibility level pale Moon maintains for Firefox extensions.
