FIREFOX BLOCKED PAGES I KNOW ARE OK

Yes, ui-deref.com got blocked in the past day or so, probably for containing malware.

If you're okay with taking the risk and the destination link (in the /r/?to= parameter) sounds alright, you can click through the dialog's warning and continue anyways, there's link inside the details for that.

I have an email account at mail.com. It seems all links are going to www.ui-deref dot com and are blocked by "Google Safe Browsing". I don't know what "Google Safe Browsing" is? I also don't know what lurks at ui-deref dot com, so I don't want to approach either of these.

Clicking on your support email to confirm subscription to this thread also gets blocked by "Google Safe Browsing" as going to/linking to ui-deref dot com. See attached image.

If neither are a Firefox problem, I assume it is at mail.com and I will try them for an answer as well.

Thanks! Chris

Yes, seems to be a Mail.com issue from all the reports — they apparently started rotating the domains they use to isolate the outgoing content and some users started to see links working again after they triggered via a different domain — so they're already trying to replace these for users.

I have this same Mail.com problem but I dont think its Mail.com's issue or at least not solely because if I open my Mail.com account in Microsoft Edge, all the ui deref links in my emails work fine

update: over the last 2 days, all the mail.com ui.deref links now appear to be working and not triggering safe browsing blocks. hopefully this is a permanent situation
