ProxyShard Extension

ProxyShard – Smart Proxy Manager is our official extension for Chrome, Mozilla Firefox, and other Chromium-based browsers (Edge, Opera, Brave, Yandex, and others). It lets you add, switch, and test proxies straight from your browser in just a couple of clicks, with no third-party software needed.

What the extension can do:

Stores an unlimited number of proxy profiles
Supports HTTP / HTTPS connections in all supported browsers
Supports SOCKS5 in the Mozilla Firefox version
One-click profile testing (latency, country, IP)
IP rotation on a timer or by hotkey for mobile proxies
Bypass lists and advanced domain routing
Localized into English, Russian, Ukrainian, and Chinese

Installation

The extension is available in the official Chrome Web Store and Firefox Add-ons. The Chrome Web Store version also installs without issues in Edge, Opera, Brave, and other Chromium-based browsers.

Once installed, open the extensions menu (the puzzle icon next to the address bar) and pin ProxyShard for quick access by clicking the pin icon next to the extension's name.

Pinning the extension — 1) Open the extensions menu. 2) Pin ProxyShard.

SOCKS5 limitation in Chromium-based browsers

Google Chrome (and other Chromium browsers) does not support login/password authentication over SOCKS5 proxies out of the box. For Manifest V3 extensions, this limitation still applies.

You can use SOCKS5 through the extension only:

without credentials (anonymous proxy), or
with IP whitelist binding

For proxies that require authentication, use the HTTP / HTTPS protocol, which is fully supported.

SOCKS5 in Mozilla Firefox

The Mozilla Firefox version of ProxyShard Extension supports SOCKS5 through the extension, so you can use SOCKS5 profiles directly in Firefox.

Setting up Residential proxies

Open your order on the Residential proxy page and configure the proxy parameters (country, region, protocol, TTL, port, etc.).
Click Generate proxy, and the generated proxy will appear in the Proxy List block on the right.
Copy the connection string with the Copy all button.
Open the ProxyShard extension (the pinned icon next to the address bar).

For Mobile proxies: IP rotation on a timer or by hotkey

When editing a profile, an IP Rotation block is available, which is especially useful for mobile proxies:

Rotation URL - paste the IP-change link from your mobile proxy order, and the extension will hit it automatically.
Trigger: Interval - rotation will run at the time interval you set.
Trigger: Hotkey - assign a key combination (for example, Shift+F2) to rotate the IP on the fly.
Track IP history - duplicate-detection feature: the extension will notify you if the same IP address repeats during your session.

Adding a profile manually

If you'd like to create a profile by hand instead of pasting a ready-made string, use the full + Add Profile form.

In the extension, open the Profiles section (via the gear / settings icon).
Click the + Add Profile button in the top-right corner.
Fill in the profile parameters:
- Name - any profile name you like
- Color - a color tag for convenience
- Type - protocol (HTTP / HTTPS is recommended)
- Host and Port - the proxy server address and port
- Bypass List - list of IPs / domains that should go directly, bypassing the proxy (one entry per line)
- Username / Password - authentication details
Click Save Profile.

The full profile creation form

Done! The ProxyShard extension is fully configured and ready to go. Switch between proxies in one click from any supported browser.
