Have been using Firefox for several years. Recently bought a new laptop with the latest Windows 10 OS. Have attempted to install a few add-ons that were installed on my older laptop with no issues. These ad-ons are being disabled because they cannot be verified. How can an add-on that was verified a week ago on another computer not be verified on a new computer? Doesn't make sense. Any answers would be helpful.

Thank you.

Current Firefox releases require extensions to be signed to prevent abuse by malware. In Firefox 43 unsigned extensions will be disabled by default. You can set xpinstall.signatures.required to false to disable this security feature in Firefox 43. In release and beta builds of Firefox 44 and later you can no longer override this.
