A Firefox proxy extension either manages proxies you bring yourself, switching between them by profile or rule, or connects you to a VPN company's own network. Decide which of the two you need, then check the last updated date, because several proxy managers haven't changed in years. Nine follow in no particular order.
Firefox's built-in proxy settings are basic, which is why proxy add-ons exist. The nine here fall into two groups: proxy managers, which work with proxies you already have, and VPN proxy add-ons, which route you through the provider's own servers.
They're listed alphabetically and in no particular order. Every number comes from each add-on's Firefox Add-ons (addons.mozilla.org) listing: author, daily users, average rating, ratings count, last updated date and the Recommended badge, as of Oct 2026. If you're thinking about proxies for social media, read whether you need an Instagram proxy first.
What I read on each listing and the nine compared
Each add-on here says on its listing that it manages proxies or works as a VPN proxy. I read the same things on every one: author, daily users, average rating, ratings count, last updated date and badge. Type and Good for come from each description. Two listings say they're free; the rest don't say, so they read Not stated, as of Oct 2026.

The SwitchyOmega listing and its successor
Proxy SwitchyOmega was last updated January 28, 2018, the oldest date on this list, and still shows 11,662 daily users. ZeroOmega, whose full listing name carries SwitchyOmega V3, was last updated September 15, 2026 and shows a 4.7 average on 83 ratings, as of Oct 2026. Both describe the same job in the same words.
Hoxx VPN Proxy has the biggest ratings count here, 10,501 on 81,059 daily users. Three more add-ons on this list were last updated before 2023, so the date is worth a look on every listing.
Which proxy add-on fits your setup
- You've got proxies from a provider: pick a proxy manager that takes your own.
- You switch between several proxies: pick one with saved profiles.
- Only some sites need a proxy: pick a rule-based switcher that turns it on and off for you.
- You don't have a proxy at all: pick a VPN proxy add-on and read whether its listing needs a payment.
Checks before you route traffic through an add-on
- Read the author line, so you know whether it's a VPN company or an independent developer.
- Check the last updated date. On this list it runs from January 28, 2018 to October 28, 2026, as of Oct 2026.
- Look for a payment flag on the listing before you sign up.
- Turn the proxy off when you're done, if you only need it for one job.

My plain advice on Firefox proxy add-ons
Work out whether you've got proxies or need someone else's. If you've got them, a proxy manager that's still being updated is the sensible route, and the dates on this list show which ones are. If you don't, a VPN proxy add-on is simpler, but read the listing for any payment flag before you install it.
