Oh, I understand you perfectly. I also faced various problems related to popups on my browser. This popup notification bothered me a lot, and I faced the problem of getting rid of it for a long time. If you use Chrome, click on Chrome's menu icon in the upper-right corner of the browser, then select "Settings" from the list below, type "pop" into the Search settings field, and click "Site Settings," under Popups. It should say Blocked, then turn off the switch next to Allowed. If these steps do not work, you can browse
promolayer.io, as there is a lot of useful information on this topic to eliminate the problem.
