Why does Mozilla blocks third-party extension to auto login?

What extension are you talking about?

Sorry, I forgot to mentioned the extension: 1Password

Open the Add-ons Manager and check its status. Then open 1Password settings.

If there is still a problem, contact its support.

1Password support told me that it isn't possible for 1Password or other extensions to work on Mozilla's websites. Mozilla has restricted that in Firefox.

I called for more help.

There are specific domains that are excluded for WebExtensions for security reasons.

• accounts-*static.cdn.mozilla.net,accounts.firefox.com,addons.cdn.mozilla.net,addons.mozilla.org,api.accounts.firefox.com,content.cdn.mozilla.net,discovery.addons.mozilla.org,input.mozilla.org,install.mozilla.org,oauth.accounts.firefox.com,profile.accounts.firefox.com,sync.services.mozilla.com,testpilot.firefox.com

With the Firefox Password Manager you have "Fill login" and "Fill Password" in the right-click context menu as possible workarounds.

I don't know whether Lockwise is affected as well.

I do not want to use the Firefox Password Manager. Your reply makes sense to me, though.
