Return to emails (from, say, a link) Blocked by Roundcube, "for protection"
I log on to my email Inbox. I also go to another Tab, e.g. a link mentioned in an email, or another file on my PC. When I try to return to emails: Roundcube has blocked my return, to protect me against some obscure error. This happens on Firefox (necessitating shutting down the computer, not just a Re-start), but not on Internet Explorer.
How can I tell Roundcube to xxxx off ?

That isn't a firefox software so you will have to look at their site for support.
My email provider (Plusnet) have said, twice, that it is not their software. And when it has occurred on Firefox, I found recently I could still access emails on Internet Explorer.
So where does it come from ? And how can I get it to stop ?
