Introducing Safe Screen Share 2.0

Safe Screen Share 2.0 is the biggest update we've ever shipped. We rewrote the entire extension from the ground up — new architecture, new features, and a faster, more reliable blur engine that just works.

Whether you're on a client call, recording a tutorial, or presenting during a standup, 2.0 has your back. Here's everything that's new.

SmartBlur: It finds what you forgot to hide

You shouldn't have to remember every sensitive element on every page. SmartBlur scans the current page and automatically detects common sensitive information — then blurs it for you.

It currently catches:

Email addresses
Phone numbers
Credit card numbers
API keys & tokens
Social Security numbers

One click in the popup and SmartBlur runs across the page. No hovering, no selecting — it just handles it.

Meeting Mode: Joins the call before you do

Meeting Mode detects when you start a Zoom, Google Meet, or Microsoft Teams call — and automatically protects every other tab in the same window.

You get three ways to trigger it:

Off — Meeting Mode stays disabled
Ask me each time — an in-page prompt appears when a meeting is detected, letting you choose whether to activate
Automatically — blur kicks in the moment you join a call, no questions asked

And three blur actions to choose from:

Use a blur profile — applies your saved profile rules to every non-meeting tab
Use SmartBlur — runs the SmartBlur scanner on each tab automatically
Blur the entire page — full-page blur on every non-meeting tab

Meeting Mode can also hide your tab titles during the call, so participants can't see what you have open.

Blur Profiles: Different contexts, different rules

Not every situation needs the same blur setup. Blur Profiles let you save different configurations and switch between them instantly.

Create named profiles for different scenarios — “Client Calls,” “Demos,” “Recording”
Each profile stores its own set of blur rules per site
Switch between profiles with a single click in the popup
Delete profiles you no longer need

Your click-to-blur rules now persist sitewide (so blurs apply across all pages on the same domain), while area blurs remain page-specific. This means your profile covers the whole site, not just a single URL.

Faster, more reliable blur restore

In 1.x, blur rules could sometimes flash briefly before being restored on page reload. In 2.0, we rebuilt the restore engine from scratch:

Early restore — blur styles are injected before the page fully renders, so sensitive content never appears uncovered
Stronger element matching — we use a combination of CSS selectors and element descriptors to reliably find the right elements, even when the page structure changes
Multiple restore passes — the engine retries restoration at increasing intervals to catch lazily-loaded or dynamically-injected content

The result: blurs are applied faster, stick more reliably, and handle dynamic pages far better than before.

Better compatibility with modern web apps

Modern web apps use iframes, Shadow DOM, and constantly-changing layouts. Safe Screen Share 2.0 handles all of them:

Same-origin iframes — blur rules now apply inside embedded iframes on the same domain
Open Shadow DOM — elements inside web components with open Shadow DOM are blurrable
Frequently changing UIs — apps that re-render aggressively (SPAs, dashboards, real-time feeds) are now better supported with the new DOM observer

A complete rewrite under the hood

Safe Screen Share 2.0 isn't just new features bolted on top. The entire codebase was rewritten with a cleaner, modular architecture:

Background — handles extension lifecycle, meeting detection, and cross-tab coordination
Popup — redesigned UI with profile management, SmartBlur controls, and meeting mode settings
Content runtime — the script that runs on every page, handling blur application, element detection, and DOM observation
Shared modules — storage, messaging, and type definitions shared across all layers

This foundation makes it easier to ship new features faster and squash bugs more reliably going forward.
