I have FF ESR 45.6 @ Win7 running flawlessly with two legacy commercial addons installed. I do need these unsigned addons as there are no alternative software.

On the new Win10 PC and exactly same Firefox ESR 45.6 these addons show compatibility errors while installing. I have disabled signed checks and forced nightly.disableCheckCompatibility=true. No luck. Then I have copied complete profile from Win7 FF installation. Now addons do appear in about:addons. Their state is disabled with no "Enable" button.

Any ideas?

(Win7 = Enterprise x64; Win10 = enterprise_2016_ltsb_n_x64_9057894)

If you follow the "More" link for each extension to the detail page, do they show the extensions were disabled because they cannot be verified? I believe that wording is specific to the signature issue.

After copying over the profile, did you again toggle the signing requirement? (I don't think nightly preferences are relevant to the ESR release.)

I notice your Firefox identified itself as the 64-bit Windows release (on Windows 10). On Windows 7, are you running the standard 32-bit release? I'm not aware of differences in this area, but it might be relevant.

Exactly - I have messed with x64 FF on W10. I was used to Firefox being x32 only. Now it works perfectly!
