I’ve had my share of persistent sign-ins w/ AE. The captchas not too often. I had noticed that the site was redirected from the Russian Federation, and I suppose the ISPs don’t concur within the cache. Always thought this be due to traffic or website maintenance. As for the re sign-ins, there isn’t any provision to remember the user. Being they push for the mobile app, they had that feature removed.
As for the ‘floaties’ and banners, I’ve been using AdBlock Plus which lets me remove elements from the page. Until very recently the tool was great; I could multiple click on super imposed blocks and if I over did it, there was a provision to ‘undo’. These features are no longer within the drop-down. I can block but one element at a time. Buried within the Chrome Toolbar / More Tools / Developer Tools / >> (more) / Ad Block Plus / refresh page. There I can see the elements removed and re-insert.
Background: older Mac with 5 year old operating system (10.8.5), some apps not supported any longer. Chrome works (as Firefox). Have some added blockers for social media, 3rd party analytics (those that aren’t with the primary web page) and the ubiquitous UBlock Origin, Disconnect, Taper Monkey et. al. I’m comfortable with it now, eventually will have to “hackintosh” my Mac. Have the tools and the zip on hand but re-building this computer will remove some of the features I’ve been using. Did a test on my Mac mini and couldn’t read video from the external drive (using VLC) directly to my television (or any other device). Would lose many of the peripheral controls that I’ve come to enjoy on this machine. Using SoundFlower to send Bluetooth audio to bathroom and other devices. VLC to control aspects of video. Remote backup to external drive, etc, etc.
But I’ve digressed enough…
