Best Proxy Browser Extension: Top 8 Picks for 2026

Like everything else in technology today, the different options for managing and configuring proxies are numerous. One of the fastest ways is to install proxy browser extension. This allows configuring proxy settings in browser itself without needing any extra programs on the user’s machine.

In this article, I review general proxy extensions, but if you want to check the same on specific browsers like Chrome, you can read our review of the best proxy extensions for Chrome.

What Are Proxy Browser Extensions and Why Do You Need Them?

A browser proxy extension controls how your browser connects to the internet. It channels the connection from the device through a remote server in a different region. As a result, the extension changes the user's visible IP address. In other words, online activities appear to be coming from a different region entirely.

Among the most important highlights of proxy extensions for browsers are the following:

• Enable users to bypass geo-restricted content by concealing their actual geographical IP address.
• To bypass cybersecurity controls, reach blocked pages in offices and many more, extensions help you navigate with ease.
• Proxy server extensions add a layer of privacy by hiding your real IP address, but they don't encrypt your traffic on their own, so use HTTPS or a VPN on public Wi-Fi networks.
• Plugins allow users to conceal their IP address from websites, advertisers, and other potential snoopers, as well as improving online identity security.

If you need the most ‘natural’ footprint on sensitive sites, it can make sense to buy residential proxy access for browser-based workflows.

These features make proxy add-ons indispensable to a large number of users who need enhanced privacy protection, anti-censorship measures, and more freedom in enjoying various online content around the world. For long, stable sessions (e.g., work accounts and dashboards), ISP proxies are often preferred due to their more predictable routing.

Next, I'll examine the best known implementations of this tool for popular web browsers and show how to set proxies in each of them.

ZeroOmega (Proxy SwitchyOmega 3)

ZeroOmega, listed in the Chrome Web Store as Proxy SwitchyOmega 3 (ZeroOmega), is the fork I recommend instead of the original Proxy SwitchyOmega. The original FelisCatus project is no longer maintained, and the community has moved to Manifest V3 forks. If you need a proxy browser extension that supports Manifest V3, this is a good place to start. It stores several proxies and lets you switch between them easily, which helps a lot with multi-accounting.

By the way, it provides a number of additional options, like:

• the ability setup of profiles for different users with the option to switch among them;
• the setup of automatic switching for the specific IP address to be used through the “auto-switch” feature. In rotation-heavy scenarios, pairing auto-switch rules with a 4g rotating proxy can help keep IP changes smoother and more natural.;
• PAC script creation;
• keyboard shortcuts for more comfortable operating of the extension;
• error log.

With these features, one is able to accomplish almost every task, including but not limited to, evading geographical restrictions and controlling several accounts on social media and other services.

Step-by-step Proxy Setup in ZeroOmega

1. Head over to the main menu, locate the "ZeroOmega" icon, click it, and choose “Options” from the list that pops up.

   

2. Locate the “Proxy” tab, choose the appropriate connection type, and fill in the IP and port boxes. If your endpoint is IPv6-based, you can use an IPv6 proxy here as well—just enter the IPv6 address and the port in the same fields.

   

3. In case private proxies are used, click on the lock icon to provide authentication details.

   

4. Type in your username and password in the space provided in the pop-up screen. Click “Save changes” then.

   

5. Press the “Apply changes” button to finalize the setup.

   

Open a new browser tab and go to any site to determine geolocation. The IP address that is highlighted should be the same as the proxy IP.

Using ZeroOmega with private proxies gives you more flexibility across sites and projects. This add-on is free and open source, and it works in Google Chrome, Microsoft Edge, and Mozilla Firefox.

Proxy Manager

Proxy Manager is a lightweight browser proxy extension for people who want to save several proxies and switch between them in one click. It supports HTTP, HTTPS, SOCKS4, and SOCKS5, handles username and password authentication, and has been updated recently, which is why I chose it for this list.

• saved proxy profiles with one-click switching;
• import and export in JSON or protocol://user:pass@host:port format;
• a per-profile bypass list for sites that should connect directly;
• search and sorting across your proxy list;
• an IP check through the active proxy.

Step-by-step Proxy Setup in Proxy Manager

1. Click the Proxy Manager icon in the browser toolbar.
2. Choose “Add new proxy”.

Conclusion

The right proxy browser extension depends on your task. Certain extensions are designed for multi-accounting or web scraping while others are geared towards simpler tasks. In my view, ZeroOmega, FoxyProxy and Smart Proxy are the most useful for managing several accounts. Other such applications serve the purpose of region restriction bypassing or changing IP addresses for better connection anonymity. It is also recommended that a proxy browser extension be used only in combination with private proxies to guarantee quality and fast connectivity, as well as provide a high level of privacy. If you want consistent uptime and support, it’s better to buy proxy servers from a trusted provider rather than rely on public lists.
