When clicked, we should launch the sign in page in a new tab instead of routing to the preferences.

If the user is signed in, we should show their avatar as well as their email address. Clicking on their avatar should open a new tab to the preferences for managing Sync and disconnecting.

Has there been any UX input here? I know that Ryan Feeley is looking to change about:preferences#sync to avoid the "create acct" and "sign in" buttons, replacing them with something like "Sign in to Sync", all towards a future where "sync" and a "firefox account" are decoupled for other account related services. I imagine he's going to want some consistency here with about:preferences#sync (eg, why is the 'display name' not shown?).

I've CC'd him here (along with Ryan Kelly who's also involved in the "decoupling" work), but could you please attach a screen-shot of your current patch and then needinfo :rfeeley for feedback?

This is the spec for the "Sign in to Sync" button,

This is the spec for when login sync is disabled,

This is the spec for when the account is signed in and login sync is enabled,

Thanks Jaws. Ryan, you OK with that given the changes you've been discussing recently?

I have verified this issue on the latest Nightly 70.0a1 (2019-08-01) (64-bit) on Windows 10, MacOS 10.14 and Ubuntu 18.04.

• The "Sign in to Sync" button and the message is displayed on the top of about:logins page.
• When click on the "Sign in to Sync" button it redirects you on the Sign In FxA page in a new tab.
• After you logged in, on the about:login page the "Sign in to Sync" button is replaced by email address + avatar.
• If the avatar is clicked you are redirected to the manage FxA account page.

Is there still time to update capitalization on the string? It should read Sign In to Sync

My fault for not catching this sooner. The word “In” should capped here because "Sign In" functions here as a compound verb, and "in" does not stand alone as a preposition.

Without wanting to derail fixing this string in particular, it's worth noting we're fairly inconsistent here - https://searchfox.org/mozilla-central/search?q=sign%20in%20to

It's an inconsistency I'd very much like to fix. Would you recommend I file bugs for those other instances?

This would not apply to full sentences that use the phrase "Sign in to," but for buttons only. For example, Create or sign in to your { -fxaccount-brand-name } on the device where your logins are saved would remain as-is.

Can you please file bugs for these other ones, including a new bug to get the capitalization fixed for the string from this one? Feel free to leave links to the new bugs you file here.
