Try going to Settings and turning off Block Pop-up Windows.

Thank -you!!

Same problem and I don't have pop-ups blocked. Any other ideas?

Hmmm..

1. Settings 2. Tracking Protection 3. Standard

Yes, that's what I have. And I haven't touched it since this started. Plus it's only on some websites. It's very weird.

What settings? Firefox settings? I phane settings?

Firefox settings.

This Happens for me as well since about a week now. And it concerns all webpages and sites all the time :(

Didn’t change Firefox fir iOS-settings Didn’t change iPhone settings.

Have tried all sorts of changes in settings with respect to popup windows, tracking allowance, cookies, data usage restrictions and more

Nothing helps.

And in Safari everything works just fine all the time. So now I’m forced to use safari in stead :(
