Another method is using "about :config".
1. Type about:config in Firefox addressbar and press Enter. It’ll confirm, click on I’ll be careful, I promise! button.
2. Now right-click and select “ New -> Boolean“. Give it name extensions.checkCompatibility and set its value to false.
3. Again right-click and select “ New -> Boolean“. Give it name extensions.checkUpdateSecurity and set its value to false.
4. That’s it. You have done. Restart your browser and now all disabled extensions will be enabled and you’ll be able to install new incompatible extensions as well.
