@slytheringirl I appreciate the suggestion! I hope I didn't sound ungrateful.

@slytheringirl First time, I got an API error, then I got a 403 error.

If I'd have known I'd have lost functionality like this, I wouldn't have done it.

Is there going to be a workaround for this? I'd hate to think that by using a built-in security feature that I'd lose a feature that I really liked about Opera.

I'd like to see this optional instead of mandatory as well, please. Opera for Android is the only browser that still lets me use Facebook Messenger from the mobile website, instead of having to use the basic mobile site or the desktop site, but this feature/bug is enough of an irritant that I'm also using Brave or Firefox more often, when I'm not going on FB.

@petesherwood I had the same issue for a while at home. I noticed that it happened when I used ANY Chromium-based browser, so I contacted the Chromium team. It looks like it's a fairly common issue. I'm glad that helped you as much as it did me!

I had a similar issue at home, with my network. I turned off this feature (in Comment #26) and it resolved my issue. Hopefully this will help you as well.

Since we can't install extensions in the mobile browser, is there any way we can increase privacy with features like forcing HTTPS wherever possible or doing a better job of blocking trackers?

According to EFF's Panopticlick (https://panopticlick.eff.org/), Opera Mobile blocks some tracking ads and invisible trackers, but not all and does not block trackers from "acceptable ads".

I far prefer Opera to Firefox mobile browsers, but I usually use Firefox because I feel that I have more control over my personal privacy.

Can we investigate ways to improve privacy management on Opera Mobile (and by extension Opera Mini)?

@burnout426 I think I've also had some luck with using mail.office365.com as the SMTP server.

@treego As I said, I'd rather not have to rely on an extension. I use Mercury Reader only because Opera doesn't already have the feature built-in, like other browsers have.

I'd like to see the option to switch back and forth between those two options.
