BROWSER Tab

A full Chromium browser. All traffic is automatically captured to DEVTOOLS — no need to open anything.

Overview

The BROWSER tab is where you actually browse the web. Everything you do here is automatically captured in the DEVTOOLS tab.

JavaScript Toggle

Disable JavaScript to:

Bypass client-side bot detection
Speed up page loading
Avoid popups and modals

When disabled, the page reloads without JavaScript.

CSS Toggle

Disable stylesheets to:

View raw HTML structure
Extract data without styling interference
Debug layout issues

text

CSS Toggle: ON  → Stylesheets enabled (default)
CSS Toggle: OFF → Raw unstyled HTML

Save bandwidth
Speed up page loading
Avoid tracking pixels

text

IMG Toggle: ON  → Images load normally (default)
IMG Toggle: OFF → Images blocked (empty placeholders)

Blocked images show as empty boxes or alt text.

New Tab Interception

The Problem

Some sites (especially streaming sites) open new tabs to trigger player URLs. In a normal browser, this would break your capture session.

The Solution

Nothing Browser intercepts new tab requests and loads the URL in the current tab instead.

Normal browser:
  Click video → New tab opens → Capture lost ❌

Nothing Browser:
  Click video → URL loads in same tab → Capture continues ✅

This is intentional. It keeps the capture session intact and prevents the player URL from being missed.

Technical Details

cpp

// New tab interception
void BrowserTab::onNewWindowRequest(const QUrl& url) {
    // Instead of opening new tab, navigate current tab
    m_webView->setUrl(url);
    // Capture continues uninterrupted
}

Fingerprint Injection

The fingerprint spoofing script is injected at DocumentCreation — before any page JavaScript runs.

Injection Timing

Timeline:
────────────────────────────────────────────────────────────►

DocumentCreation     Page JavaScript     User Interaction
       │                    │                   │
       ▼                    ▼                   ▼
  Fingerprint        Page sees already    Everything works
  injected           spoofed values       normally

What Gets Spoofed

Property	Spoofed Value
`navigator.webdriver`	`undefined`
`navigator.plugins`	Chrome plugins (PDF, etc.)
`navigator.languages`	`['en-US', 'en']`
WebGL vendor	`Intel Inc.`
Canvas	Per-pixel noise (xorshift)
Audio	±0.00000005 noise

Scope

✅ Every page
✅ All iframes
✅ All sub-frames
✅ All navigations

Known Blocks

The following sites actively detect non-standard browsers and may block or degrade functionality:

Site	Status	Reason
Google Search	⚠️ May block	Advanced fingerprinting
Gmail	⚠️ May block	Account protection
Google Drive	⚠️ May block	Security measures
Facebook	⚠️ Often blocks	Bot detection
Instagram	⚠️ Often blocks	Bot detection
WhatsApp Web	⚠️ May degrade	Automation detection
Banking sites	⚠️ Often block	Security policies
Netflix	⚠️ May block	DRM requirements
Spotify Web	⚠️ May work	Less strict

Why They Block

These sites use multiple detection methods:

TLS fingerprint — JA3/JA4 (Nothing Browser passes this)
JavaScript properties — navigator.webdriver, chrome.runtime
Behavioral analysis — Mouse movements, typing patterns
Canvas/WebGL fingerprinting — GPU rendering patterns

Workarounds

Solution	When to Use
Use headful mode	Sites detecting headless
Enable human mode	Behavioral detection
Use YOUTUBE tab	For YouTube content
Try Private Browser	Different fingerprint profile

This is expected behavior. These sites go beyond standard bot detection.

Back/Forward

Use mouse buttons (if available)
Right-click → Back/Forward
No toolbar buttons (use keyboard or mouse)

Keyboard Shortcuts

Shortcut	Action
`Ctrl+L`	Focus URL bar
`Ctrl+R`	Reload page
`Ctrl+Shift+R`	Hard reload (ignore cache)
`Alt+←`	Go back
`Alt+→`	Go forward
`Ctrl+F`	Find in page
`Ctrl+Shift+J`	Open DEVTOOLS

Reload Types

Action	Effect
Normal reload	Load from cache if available
Hard reload (Ctrl+Shift+R)	Ignore cache, fresh request

Capture Integration

Everything in the BROWSER tab is automatically captured:

Action	Captured In
Page navigation	NETWORK tab
API calls	NETWORK tab
WebSocket messages	WS tab
Cookies set	COOKIES tab
Storage writes	STORAGE tab

You don't need to do anything. Capture runs automatically.

Troubleshooting

Page Not Loading

Solutions:

Check URL is correct
Check internet connection
Try disabling JS/CSS/IMG toggles
Check status dot color

Capture Not Showing

Solutions:

Switch to DEVTOOLS tab
Check you're on the right sub-tab (NETWORK, WS, etc.)
Click CLEAR and try again

Site Looks Wrong

Solutions:

Check CSS toggle is ON
Check JS toggle is ON (sites need JS)
Try reloading the page

Site Detects Automation

Solutions:

Use headful mode: binary: "headful"
Enable human mode: piggy.actHuman(true)
Try Private Browser for better anonymity
