I set up and test proxies inside antidetect browsers on a regular basis, and Octo Browser is one of the tools buyers ask about most. The setup is short, and Octo does most of the work for you, including auto-detecting the proxy format and checking the exit IP before you launch a profile. This guide walks through the whole process with real screenshots, from claiming the trial to confirming a clean fingerprint on Pixelscan. Here is the quick version before the full walkthrough.
TL;DR
Create a profile in Octo Browser, then paste your full CatProxies proxy string into the proxy field. Octo auto-detects the format and checks the connection, showing the exit IP and country before you start. Select HTTP or SOCKS5 to match your plan, leave the fingerprint on default, and start the profile.
For the format: paste the whole proxy line and let Octo split it into host, port, login, and password.
For the protocol: HTTP or SOCKS5 is not auto-detected. You must set it to match your CatProxies settings.
Core point: one generated proxy is enough for one browser profile.
Key Takeaways
You only need one proxy per browser profile. The proxy count in the generator controls how many you create, not how many a single profile needs.
Octo Browser auto-detects the proxy format, but not the protocol. HTTP and SOCKS5 must be selected by hand to match your plan.
The built-in Check Proxy button confirms the exit IP and country before you launch, so you can catch a wrong or dead proxy early.
The first time a profile launches, Windows asks you to allow the browser through the firewall. This is normal and you should allow it.
Static ISP proxies are the better choice for long term browsing and account management, because the IP stays stable over time.
How This Was Set Up
The steps below come from a live CatProxies plan and a real Octo Browser 3.0.7 install on Windows 11. Each screenshot shows the actual settings used, including the built-in proxy check, the Windows Firewall prompt, and the final Pixelscan test. The exit IP in the examples is a German address, so you can compare what Octo reports against what an independent checker reports.
Step 1: Install Octo Browser and Claim the Trial
Register at octobrowser.net, download the browser, and open the plan screen. If you received a promo code by email, click the "Have a promo code?" link at the top and enter it there to claim a two day trial.
The Octo Browser plan screen. Click "Have a promo code?" to enter a code and claim the trial.
The trial runs for two days and lets you create up to ten profiles. That is enough to add a CatProxies proxy, check it, and run a full fingerprint test before you decide on a paid plan.
When you move to a paid plan, use the code CATPROXIES30 for 30% off your first Octo Browser subscription.
Step 2: Create a Profile
Open the Profiles screen and click Create Profile. On a fresh trial the list is empty and shows your profile count, for example 0 of 10.
The Octo Browser profiles dashboard. Click Create Profile to start a new profile.
Give the profile a name. The panel on the right previews the fingerprint Octo will use, including user agent, operating system, screen resolution, timezone, and WebRTC handling. Leave these on default unless you know exactly what you are changing, then click "Set a new proxy".

Step 3: Add Your Proxy and Set the Protocol
Select the protocol first, then paste your proxy. The protocol is the only field Octo cannot detect on its own, so set HTTP or SOCKS5 to match your plan. Then paste the full proxy string into the host field, and Octo splits it into host, port, login, and password for you. Any CatProxies plan works here, including residential proxies and static ISP.
Set the protocol to HTTP or SOCKS5, paste the full proxy, then use Check Proxy to confirm the exit IP and country.
Click Check Proxy. Octo tests the connection and shows the exit IP with a country flag, in this example a German address. If the check fails, the most common cause is the wrong protocol, so switch between HTTP and SOCKS5 and try again. Click Confirm, then Create Profile.
Step 4: Start the Profile
Back in the profile list, the proxy appears under the profile with the exit IP and country. Use the start button next to the profile to launch it. You can re-run the proxy check at any time from here to confirm the IP and location still match before you browse.

Step 5: Allow Octo Through Windows Firewall
The first time you launch a profile, Windows shows a security prompt asking whether to allow the browser to access public and private networks. Click Allow. This is the standard Windows Defender Firewall request that appears the first time a new application opens a network connection. The publisher shows as the browser vendor, and the prompt is not specific to proxies. Allowing it lets your profiles reach the internet through the proxy. If you block it, pages may fail to load. You normally see this only once.

Step 6: Verify the Fingerprint with Pixelscan
After the profile opens, confirm the setup with an independent fingerprint checker. Open pixelscan.net inside the profile and run the scan. A clean result reports a consistent fingerprint, no proxy detected, and no masking detected, with the location matching your proxy exit.
A Pixelscan result for an Octo Browser profile: fingerprint consistent, no proxy detected, and the location reported as Germany, matching the proxy exit.
The Germany result here is the proxy exit, not your own connection. A location that matches the proxy is the outcome you want, and it confirms your real IP is not leaking through the profile.
Step 7: Extensions and Templates (Optional)
Octo Browser lets you add Chrome extensions to profiles and save reusable templates. Open the Extensions screen to add an extension from a file or a Chrome Web Store link, then apply it to the profiles that need it. Templates let you reuse a fingerprint and settings across many profiles, which saves time when you run several at once.

Which Proxy Type to Choose for Octo Browser Profiles
For normal browsing and social media management, static ISP proxies are the better fit, because the IP stays stable over the long term. For account creation, residential proxies or mobile proxies are the usual recommendation. The more often an account changes IP, the worse it tends to be for account status, so a stable IP matters most for long term work.
| Proxy type | Best use for browser profiles | Static long term? |
| Static ISP | Normal browsing and social media management | Yes |
| Residential | Account creation | No, static is best effort only |
| Mobile | Account creation and hard targets | No, static is best effort only |
Octo Browser is a common choice for running many profiles at once, for example for sneaker releases, retail restocks, and social media management. For sneaker and retail work, each checkout profile needs its own clean IP, so mobile proxies or fresh residential IPs are common. For profiles you keep for months, static ISP proxies are the honest choice for a stable long term address.
There are no genuine long term static residential proxies, because nobody can guarantee a residential peer stays connected to a network sharing app. A provider that sells long term static residential proxies is either mislabelling them or sourcing from a botnet of infected devices. For a stable long term IP, static ISP proxies are the reliable option.
Common Misconceptions
"Octo detects the protocol along with the format." It does not. Octo fills in host, port, login, and password automatically, but HTTP and SOCKS5 are not auto-detected. Select the protocol to match your CatProxies plan, or the profile will fail to connect.
"The Windows Firewall prompt means Octo is unsafe." No. It is the standard Windows Defender Firewall request that appears the first time the browser opens a network connection. It is not specific to proxies, and allowing it simply lets your profiles reach the internet.
"If Pixelscan shows Germany, my real location leaked." No. Pixelscan reports the exit location of the proxy, which is the German CatProxies IP, not your own connection. A result that matches the proxy confirms it is working, not that anything leaked.
"I have to pay for Octo before I can test a proxy." No. The promo code trial gives you two days and up to ten profiles, which is enough to add a CatProxies proxy, check it, and run a full Pixelscan test before you buy.
Frequently Asked Questions
Do I need a paid Octo Browser plan to add a proxy?
No. A promo code from Octo Browser unlocks a two day trial with up to ten profiles. That is enough to add a CatProxies proxy, run the built-in check, and confirm the fingerprint with Pixelscan before you commit to a paid plan.
Does Octo Browser auto-detect the proxy format?
Yes, for the format. Paste the full proxy string and Octo splits it into host, port, login, and password automatically. The protocol is the exception. You must select HTTP or SOCKS5 by hand to match your CatProxies settings, or the connection will fail.
Why does Octo Browser ask to allow it through Windows Firewall?
Because it is opening a network connection for the first time. Windows Defender Firewall prompts you the first time any new application tries to reach public or private networks. The request is not specific to proxies. Click Allow so your profiles can connect through the proxy. You normally see this only once.
How do I check a proxy in Octo Browser before starting a profile?
Use the Check Proxy button in the proxy dialog. Octo tests the connection and shows the exit IP with a country flag, so you can confirm the IP and location before you launch. If the check fails, the most common cause is the wrong protocol, so switch between HTTP and SOCKS5 and try again.
How many proxies do I need for Octo Browser profiles?
One proxy per profile. The number in the CatProxies generator controls how many proxies you create, not how many a single profile needs. If you run five profiles at once, you use five proxies, one for each.
Which CatProxies proxy type is best for Octo Browser?
Static ISP proxies are best for long term browsing and social media management, because the IP stays stable. Residential and mobile proxies are better for account creation. Frequent IP changes tend to hurt account status, so a stable IP is preferable for profiles you keep for a long time.
How do I confirm an Octo Browser profile is set up correctly?
Start the profile, then open Pixelscan inside it and run the scan. A correct setup reports a consistent fingerprint, no proxy detected, no masking detected, and a location that matches your proxy exit. If the location matches and the fingerprint is consistent, the profile is ready.
Can I add extensions to Octo Browser profiles?
Yes. Open the Extensions screen and add an extension from a file or a Chrome Web Store link, then apply it to the profiles that need it. You can also save templates to reuse a fingerprint and settings across many profiles at once.
Set up correctly, Octo Browser gives each profile a clean, consistent fingerprint on a stable CatProxies IP.
Try CatProxies. Static ISP proxies that hold the same address for months, plus residential and mobile pools for account work. See CatProxies plans.
