hi PritamChaudhari, please see the banner at the top of the support page - unfortunately there's a technical issue (failing addon signature verification) at the moment that's prohibiting the installation and in some case the usage of installed addons for firefox.

mozilla is working on a resolution, expect a fix soon. sorry for the inconvenience...

There was a Bug-A-Boo with a Certificate Expiration Date dealing with the Add-ons. There's a new FF Version with the main Fix, 66.0.4.

Mozilla Blog Post Update:
A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061).
There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week. More information about the remaining issues can be found by clicking on the links to the release notes above.
