Working with dozens of accounts requires more than time. You also need the right tools. Each account should have its own browser profile with a separate digital fingerprint, cookies, and proxy. At the same time, creating, configuring, and using all these profiles should be convenient.

This is a familiar challenge for affiliate marketers, SMM specialists, e-commerce teams, crypto projects, and people working with browser automation. Whatever the field, the goal is similar: keep accounts separate, avoid unnecessary risks caused by inconsistent settings, and manage hundreds of profiles without getting buried in repetitive work.

If you want to change the IP address websites see when you browse in Firefox, you can configure a proxy in the browser settings or use the ProxyControl extension. A proxy provides a different public IP address; Private Browsing does not.

In Firefox 152 and later, proxy settings sit under Settings > Privacy and security > Connection and software security > Advanced settings > Configure proxy, not on the General page that most older guides describe. According to StatCounter's September 2026 browser version data, Firefox 155 and 156 alone accounted for 3.27 percentage points of Firefox's roughly 6.1% worldwide desktop share, so most Firefox users already see the new layout. A proxy changes the IP address that websites see, which Private Browsing does not: Mozilla's support article on private browsing myths states, “It doesn't hide your IP address or your location.”

In this article we will consider how to use proxies to work with API. We will show how to add a proxy to the code to, for example, change geolocation.

Bots generated 53% of web traffic in 2025 and 27% of bot attacks were aimed at APIs, according to IT Brief's summary of the Thales 2026 Bad Bot Report. Akamai's 2026 State of the Internet report counted 113% more daily API attacks than a year earlier. That is why API providers rely on rate limits and IP allowlists. The address your requests come from, and how steadily you send them, now decide whether an integration keeps working.

What are APIs and why do you need them?

An API (application programming interface) is like a menu in a restaurant. Instead of cooking yourself, you choose from the menu and the chefs (or APIs) do all the work.

APIs allow programs to share data and functions. For example, an online store can process payments through APIs without needing a deep understanding of how payment systems work.

A dedicated proxy is an IP address rented to one customer at a time: for the length of the rental, no one else’s traffic leaves through it. In October 2026 a dedicated IPv4 address costs from $1.47 a month on the Proxys.io pricing page, roughly 2.2 times the $0.67 price of a shared address that up to three customers use at once. What the extra money buys is control. Every request the address sends is yours, and so is every rate limit it runs into. A dedicated address still shows up as a hosting IP, and it won’t make a slow route any faster.

Bots generated more than 53% of all web traffic in 2025 and people only 47%, according to the Thales 2026 Bad Bot Report, which classifies 40% of all traffic as malicious. That is why it matters who else uses your proxy address: websites now score an IP address before they look at the visitor, and the record of that address counts alongside your own behavior. "The challenge is no longer identifying bots. It’s understanding what the bot, agent, or automation is doing," said Tim Chang, Global Vice President and General Manager of Application Security at Thales.

The 11 best proxy providers in this ranking charge from $1.00 to $8.00 per GB of residential traffic, so the real choice comes down to proxy types, locations and payment terms. PROXYS.IO is the best proxy provider overall: it offers five proxy types (datacenter IPv4, IPv6, ISP, residential and mobile), a 100M+ residential IP pool in 195+ countries, HTTP(S) and SOCKS5 support, and 24/7 support.

Top proxy providers compared: proxy types, locations and pricing

Ten of the 11 providers list 190 or more countries, so proxy types, crypto support and unit price separate them more than coverage does.

The guide covers three platforms: Squid on a VPS for an HTTP/HTTPS proxy, 3proxy on a VPS for SOCKS5 and HTTP, and Squid on a Raspberry Pi for a proxy with your home IP address. The last section compares what each setup costs with renting proxies.

How to make a Squid proxy server on a VPS (Ubuntu)

Squid on an Ubuntu 24.04 or 26.04 LTS VPS works as a private HTTP/HTTPS proxy on TCP port 3128 that serves only clients with a valid username and password.

Bottom line: unlimited residential proxies pay off when monthly volume exceeds the flat fee divided by your per-GB price. In practice that means headless-browser collection and hard anti-bot targets; compressed HTML scraping rarely reaches that line, and small API calls get cheaper on sticky sessions or per-IP plans.

• “Unlimited” never means no limit: the gigabyte counter is replaced by another cap.
• The collection method sets the bill: a full browser load of a home page used 111 times more data than a compressed HTML fetch.
• Per-GB plans carry hidden multipliers: missing compression, a new IP on every request and retries on hard targets.
• Before paying, test success rate, throughput, session uptime and the fair use rule on your own targets for at least 24 hours.

"VPN/proxy detected" on YouTube means YouTube has classified your connection's IP address as a VPN, proxy, hosting network or privacy relay, and the video or channel you opened won't play over it. The screen says "To continue, turn off your VPN/proxy." If you don't use a VPN, the cause is hidden routing on your device or an ISP address that databases mislabel.

Key points

• Any VPN or proxy blocks playback on YouTube TV, Primetime channels and restricted channels, by rule.
• On regular YouTube, only channels that chose to restrict playback show the error.
• Detection is a score built from IP databases, ASN, shared IPs and browser or network mismatches.
• Without a VPN, the cause is hidden routing or a misclassified ISP address.
• Check in this order: direct connection, hidden routing, IP classification, location settings, then clear the cache.

Private Internet Access runs one SOCKS5 proxy server, proxy-nl.privateinternetaccess.com on port 1080, in the Netherlands. Setups in a single app or in Multi-Hop usually fail for one of three reasons: the wrong login, a hostname where the app expects an IP, or a browser that can't send a SOCKS5 password.

Does Private Internet Access offer a SOCKS5 proxy?

Yes. PIA's help center documents a SOCKS5 proxy at proxy-nl.privateinternetaccess.com, port 1080, set up with credentials generated in your PIA account. There is nothing extra to download.

The proxy has its own login: your account username starts with "p" (p1234567), while the SOCKS5 username starts with "x" and has its own generated password. PIA's settings guide describes the SOCKS5 option as an unencrypted proxy that masks your IP address, so only traffic the app encrypts itself, such as HTTPS, stays private.
