I had the same problem when I started taking orders from European clients. Some websites opened differently, ads didn't match, and some services blocked access altogether. At first, I thought it was a minor issue, but over time I realized that without a proxy, it would be impossible to work properly.
I spent a long time looking for something simple, without any complicated settings, and accidentally came across a review of https://www.psu.com/news/first-15-minutes-with-floppydata-for-easy-proxy-setup/ . What interested me was that the focus was not on technical details, but on real-life use from the very first minutes. In the life of a freelancer, it's important not to "spend half a day figuring it out," but to get the job done quickly. That's exactly what this is about: I chose a country, got an IP, connected — and it works. For me, it became a tool that relieved constant stress and gave me a sense of control over my workflow.
