Switching From AdsPower to JustBrowser: A Step-by-Step Migration Checklist

Last month I watched someone in a Discord server post a screenshot of AdsPower crashing mid-session. Forty-two browser profiles open, local sync corrupted, no cloud backup configured. Two years of warmed-up profiles — gone.

The thread went quiet. What do you even say?

I don't know if it was a local database issue, a sync conflict, or something else. AdsPower fixed the crash in a patch three days later. But that person's profiles were already toast. No backup, no recovery.

That incident sat with me. I'd been running AdsPower for about eighteen months at that point. Mostly stable, cheap entry tier. But I started wondering: what happens to my profiles if something corrupts? Where's the exit plan?

So I migrated to JustBrowser. Twenty-seven profiles across Facebook Business Manager, Amazon seller accounts, and some TikTok Shop storefronts. Every one of them made it over without a flag.

Here's exactly how I did it.

What You'll Have at the End

A repeatable migration workflow. Cookies exported. Proxies re-bound. Fingerprints validated on CreepJS and Pixelscan before you touch production accounts.

Not instant — budget 15-20 minutes per profile for anything that matters. But you only do it once, and honestly I wish I'd done this sooner instead of white-knuckling every AdsPower update.

Prerequisites

Before starting:

AdsPower installed with profiles you're migrating
JustBrowser downloaded — 7-day trial gives 5 profiles for testing
Cookie export extension installed (EditThisCookie or Cookie-Editor)
Proxy credentials documented — host, port, username, password for each profile
60-90 minutes for your first batch of 3-5 profiles

If you're moving more than 10 profiles, grab JustBrowser Pro ($9.99/mo for unlimited profiles) before you start. Easier than running the trial clock out mid-migration.

Step 1: Document Everything in AdsPower First

I know. You want to jump straight to exporting cookies. Don't.

Open AdsPower and build a migration spreadsheet. For each profile:

Profile Name	Platform	Proxy Type	Proxy Host	Timezone	Last Active	Priority
TT-Shop-01	TikTok Shop	Residential	us.oxylabs.io:10001	America/Chicago	2026-06-18	Critical
FB-BM-Main	Facebook BM	ISP	iproyal.com:30400	America/New_York	2026-06-19	High
AMZ-DE-02	Amazon.de	Datacenter	185.xxx.xxx.xxx:8080	Europe/Berlin	2026-06-15	Medium

Why bother with this? Because proxy IP consistency is everything.

If your TikTok Shop account has been logging in from the same Oxylabs residential IP in Chicago for six months, and you accidentally configure a different provider or region in JustBrowser — you've just created a location anomaly. The timezone and geolocation guide explains what detection systems actually look for.

The boring spreadsheet saves you from the expensive mistake. I learned this the annoying way — spent two hours debugging a "ban" that was actually just me fat-fingering a port number.

Step 2: Export Cookies from AdsPower

AdsPower doesn't have a universal "export all cookies" button. You'll extract them per-profile. Yeah, it's tedious.

Method A: Browser extension (recommended for most people)

Open the AdsPower profile you're migrating
Navigate to the platform — Facebook, Amazon, TikTok, wherever
Confirm you're logged in. Stale sessions export worthless cookies.
Click EditThisCookie → Export → Netscape format or JSON
Save the file: tt-shop-01-cookies.json

Method B: AdsPower local API

AdsPower runs a local API on port 50325. If you're technical:

# Get browser debug port for a profile
curl "http://127.0.0.1:50325/api/v1/browser/start?user_id=YOUR_PROFILE_ID"

# Then connect via CDP to extract cookies programmatically

This is faster for bulk migrations, but requires scripting.

The critical part: Export cookies while actively logged in. If your last session was two weeks ago, open the profile, confirm you're authenticated, then export. Server-side session expiration makes old cookie exports useless.

For each profile, you should now have: a cookie file + proxy credentials + documented settings.

Step 3: Create Matching Profiles in JustBrowser

Open JustBrowser. Create a new profile. This is where precision matters.

Settings that MUST match your AdsPower profile:

Operating System: Windows 11 in AdsPower → Windows 11 in JustBrowser. macOS stays macOS.
Timezone: Must match proxy location. Chicago proxy = America/Chicago. Period.
Language: Must match proxy location. US proxy = en-US primary.
Screen Resolution: Match exactly. 1920x1080 → 1920x1080.

Settings that can differ:

Canvas hash — different engines produce different hashes. Expected.
WebGL renderer — will regenerate. Fine.
Audio fingerprint — same deal.

Here's my honest take — and plenty of people disagree: fingerprint paranoia is mostly overblown for migrations. Most people stress about canvas hashes when they should be triple-checking their proxy config.

Platforms weight IP + timezone consistency far more heavily than hardware fingerprint values. Browsers legitimately change fingerprints when users update, reinstall, or switch machines. What doesn't change? Your network location pattern.

(I've argued about this in too many Discord threads to count. Still my hill to die on.)

Proxy configuration:

Enter your existing proxy credentials exactly. Same host, same port, same auth.

JustBrowser has a built-in proxy tester. Use it. If the returned IP or country differs from what you expect — stop. Debug before continuing.

I've watched someone type a port number wrong and burn a $25K/year Amazon seller account. One wrong digit. Check every field, then check again.

Annoying? Sure. But cheaper than explaining to a client why their account got suspended.

In JustBrowser's profile settings, find the cookie import option. Paste JSON directly or upload the Netscape format file.

After importing: launch the profile, navigate to the platform, check if you're logged in.

Logged in? Move to fingerprint validation.

Logged out? Something broke. Common causes:

Expired cookies — Session died server-side. You'll need to log back in.
Format mismatch — Strip to essential fields: name, value, domain, path, expiration. Some AdsPower exports include extra metadata that breaks import.
Domain mismatch — Cookies for .amazon.com don't apply to amazon.de.

Re-logging isn't catastrophic. IP and timezone match your historical pattern? One "new device" login looks like... a new device. Normal human behavior. Have 2FA recovery codes ready. The cookie isolation guide covers session handling in detail.

Step 5: Validate Fingerprints on CreepJS Before Production Use

Do not skip this.

I skipped it once on what I thought was a "low priority" test profile. Turned out that profile was connected to a business PayPal through a linked Facebook account. Lesson learned — I still cringe thinking about it.

Before using the migrated profile on any account that generates revenue:

Launch the profile in JustBrowser
Navigate to CreepJS
Wait for the full report (10-15 seconds)
Check the Lies section — should be empty or minimal
Note the Trust Score — aim for 80%+

What you're looking for:

Lies section: Empty is ideal. Red entries = detectable inconsistencies between spoofed values.
Trust Score: 80%+ is solid. Below 65% = misconfigured profile.
Consistency: Run the test twice. Same hashes both times? Good. Values changing randomly = stability issue.

Also run Pixelscan and BrowserLeaks. The CreepJS walkthrough explains what each metric means and which ones actually matter.

If something fails: check timezone vs proxy location first (causes 60% of issues), then language settings, then OS/browser consistency.

Step 6: Warm Up the Migrated Profile

Your cookies carry session state. But account-age signals extend beyond cookies.

JustBrowser includes a cookie warm-up engine that visits 127 curated sites to build browsing history. Run it on migrated profiles — it takes maybe five minutes and reinforces the profile's age signals.

For the first 48-72 hours post-migration:

Keep activity patterns consistent with previous behavior
Don't suddenly run 10x more actions than usual
Avoid heavy automation until you've confirmed stability

If you're using Playwright or Puppeteer for automation, the antidetect REST API guide covers programmatic profile launch.

Step 7: Migrate in Batches, Not All at Once

Don't migrate your most valuable profile first.

I've told maybe forty people this. At least fifteen of them ignored me. Guess which ones regretted it.

Pick 2-3 profiles that matter but aren't critical. Run them in JustBrowser for a full week with normal activity. Watch for:

Unusual CAPTCHA frequency
Verification prompts you didn't get before
Session instability

No issues after a week? Migrate the rest. Problems? Debug before touching high-value accounts.

Common Errors and Fixes

Cookies imported but session is gone

Cause: Cookies expired server-side, or you exported while logged out.

Fix: Log back into the account from the JustBrowser profile. As long as IP + timezone match your historical pattern, one new-device login is normal. Have 2FA recovery codes ready.

Proxy connection fails

Cause: Credentials wrong, or your proxy provider requires IP whitelisting.

Fix: Double-check every field. Some providers (Bright Data, Oxylabs, IPRoyal) require you to whitelist your machine's IP. If you're migrating from a different machine than you used with AdsPower, add the new machine's IP to your provider's allowlist. The ISP proxy tutorial covers provider-specific setup.

CreepJS trust score dropped vs AdsPower

Cause: Fingerprint settings don't match proxy location, or there's an OS/language inconsistency.

Fix: Verify timezone = proxy timezone, language = proxy country language, OS = consistent with profile history. Disable all browser extensions during testing — some extensions modify fingerprint APIs in detectable ways.

Profile performance feels sluggish

Cause: Usually proxy latency, not the browser.

Fix: Test proxy speed independently. Slow proxy = your provider's problem, not JustBrowser's. Check hardware acceleration settings if local rendering feels off. And don't run 25 profiles on a laptop that struggles with 8. (Speaking from painful, fan-screaming experience.)

The Pricing Math

Let me be direct: JustBrowser isn't always cheaper than AdsPower's entry tier.

AdsPower starts at $9/mo for their lowest tier. JustBrowser Pro is $9.99/mo (or $99.99/year). On paper, AdsPower looks cheaper.

Here's what shifts the math:

AdsPower's $9/mo tier gives you 10 profiles. Their $50/mo tier gives you more. Team seats are $10/seat/month.

JustBrowser Pro at $9.99/mo includes unlimited profiles. Team seats are free and unlimited.

50+ profiles? JustBrowser wins. 10 profiles forever? AdsPower's entry tier is fine. I'm not going to pretend otherwise.

JustBrowser offers a 7-day trial — unlimited profiles, card required, nothing withheld — so you can test migration before committing. That's how I started. Migrated two throwaway profiles, ran them for ten days, then upgraded.

Run the numbers for your situation. I'm obviously biased, but the spreadsheet doesn't lie.

Next Steps

Once your test profiles run clean for a week:

Batch migrate remaining profiles — Gets faster with practice. 5-10 profiles per hour is realistic.
Run parallel for a month — Keep AdsPower active until you're confident. Don't rage-cancel.
Set up ongoing fingerprint checks — Detection tools evolve. Monthly CreepJS runs keep you ahead.

For click fraud protection on ad accounts running through your migrated profiles, ClickzProtect monitors for fraudulent clicks — their click fraud detection guide explains what signals to watch. For privacy-respecting analytics across profiles, JustAnalytics handles conversion tracking without third-party cookies — see their getting started guide.

Migration is tedious. Boring work that requires attention to detail exactly when you want to rush. Nobody enjoys this — I certainly didn't.

But if the pricing works out and you want local-first profile storage with optional unlimited cloud sync, the switch is worth the afternoon of careful work. Take your time. Validate everything.

And seriously — don't migrate your most valuable profile first.

Frequently Asked Questions

Can I export AdsPower profiles directly into JustBrowser?

No direct import exists. AdsPower profiles are locked to their proprietary format. You'll export cookies manually via browser extension or AdsPower's local API, document proxy credentials, then recreate profiles in JustBrowser with matching timezone, language, and proxy settings. Plan 15-20 minutes per high-value profile.

Will switching antidetect browsers trigger account bans?

Not if you maintain IP and timezone consistency. Platforms weight network signals far more than browser fingerprint parameters. Keep the same proxy IP, same timezone, same language. Fingerprint changes look like normal browser updates. The danger zone: changing IPs, timezone mismatches, or losing cookies that force re-authentication.

Does JustBrowser support AdsPower's team collaboration features?

JustBrowser includes free, unlimited team seats with role-based access and a shared profile pool. If you're on AdsPower's team plan, you'll recreate team assignments in JustBrowser after migration. Profile sharing between Pro users is direct — no password exposure.

What about my RPA automation scripts that use AdsPower's local API?

JustBrowser exposes a REST API plus CDP endpoints for Playwright, Puppeteer, and Selenium. Your automation logic transfers, but you'll update connection strings and endpoint URLs. The API documentation covers migration from other browser APIs.
