¡Hola!

Thanks for reporting this.

I can reproduce this on Mozilla/5.0 (X11; Linux x86_64; rv:50.0) Gecko/20100101 Firefox/50.0 ID:20160705030222 CSet: c9a70b64f2faa264296f0cc90d68a2ee2bac6ac5

I see the below in "Browser Console" and wonder if it is related:

A promise chain failed to handle a rejection. Did you forget to '.catch', or did you forget to 'return'?

Upon restoring and then maximizing the window there's white space on both left and right borders of about:newtab (please see 1284043-restored-window.png) as opposed to a non restored about:newtab (please see 1284043-maximized-window.png)

¡Gracias!

I can't reproduce it, I'm using FF47 32 bits with resolution at 125% in Win 7.

Is it specific to the 64 bits version?

Activity Stream takes over about:newtab and about:home in 57

This is an obsolete bug and nothing similar can be reproduced on Nightly 91.0a1
20210625093436 and current version of Topsites with the given steps.
