askvortsov Are you trying to develop on the live site? I would recommend against this. You should set up a local development environment and work on your extensions there.
My question is not about extension development. Sometimes when we register a new domain, we encounter the parked page. Because this parked page is cached, I am unable to make the improvements. This screen was being cached. I've had this many times. I just waited for the solution.
For this reason, I asked you to recommend a browser that does not keep such caches. I think it makes the most sense to get things done in the incognito tab.
