I have a similar problem— after I install high Sierra, i keep getting tabs for donating to this website automatically opening on my browser every 10 minutes, and it even takes over executive control from me and redirects me to the browser from whatever app I’m actually using! Now I find that annoying, but I figured it’s just a way to nudge me into donating a few bucks, and since I got everything working fairy well I thought certainly it’s ok I think you guys deserve a donation for the good work you do. So I donated $5 and thought that would remove or turn off the ad-Ware, but I left the computer on overnight and woke up with 209 tabs open on my browser! I mean I very much appreciate this project as a shortcut to making my own but I’m a Linux guy and I’m certainly not used to *ever* having my workflow interrupted by pop-up or pop-in ads asking me for donations , let alone once every 5- 10 minutes! I mean I like this project and want to keep supporting it, but if I can’t remove that feature, realistically I can’t use the operating system other than as a curiosity on a small partition in some kinda dual boot situation , and thus couldn’t in good conscience continue to support this project. Am I missing something? Is there some easy way to solve this that I didn’t notice? It seems no one else has this problem! Anyway, thanks for your concern.
