Coming soon to the Chrome Web Store & Edge Add-ons
Real-Time Phishing Protection
Every page you open is checked instantly against 15+ phishing patterns — fake brand domains, one-letter typosquats, lookalike characters, and more. Dangerous pages get a full-screen warning before you can type a thing.
Link Hover & Right-Click Checks
Hover over any link to see a risk badge before you click, or right-click any link and choose 'Check this link' for an instant verdict — perfect for links inside emails and chats.
One-Click Browser Clean
Wipe cookies, cache, history, and your downloads list in a single click from the toolbar popup — with your important logins protected by the exclude list.
Browser Health Score
A live 0–100 score for your browser: how many cookies have piled up, how many risky extensions are installed, how many tabs are eating memory, and when you last cleaned.
Auto-Clean Scheduler
Set it and forget it — clean automatically every day or every time the browser starts. Your excluded sites are never touched, so you stay signed in where it matters.
Per-Site Cookie Manager
See exactly which sites store the most cookies in your browser, and wipe any site's cookies individually without disturbing the rest.
Tab & Memory Optimizer
One click puts all your inactive tabs to sleep, instantly freeing memory — pinned tabs and tabs playing audio are left alone.
Extension Audit
A security review of every other extension you have installed — flagging risky permission combinations like 'can read every site you visit' so you know exactly what's watching.
Tracker Blocking
Blocks the analytics and fingerprinting networks that follow you around the web — Google Analytics, Facebook Pixel, session recorders, and more.
Ad Block
Blocks the most common ad networks — banners, sponsored-content widgets, and pop-under networks — for a faster, calmer web. Toggle it per site whenever you want.
Password-Entry Guard
The moment you click into a password field on an unencrypted or suspicious page, a warning appears — before you've typed a single character.
Download Guard
Flags risky executable downloads (.exe, .scr, .js and friends) the moment they start, and shouts loudly when the download comes from a site that looks like phishing.
Deep Clean Hand-Off
Browser cleaning is half the story — one click hands over to ETA System Doctor on your PC for registry, disk, and full-system cleanup. One Pro license covers both.
