Monosnap Chrome Extension and Manifest V3: What Changed

If a screenshot extension you relied on in Chrome stopped working, Chrome's move from Manifest V2 to Manifest V3 may be the reason: Chrome turned off extensions still built on the older format. Monosnap offers a Chrome extension; check its Chrome Web Store listing first.

Monosnap is a screenshot tool for Mac and PC from Monosnap Inc., with its own cloud storage, video and GIF recording, and an image editor.

The Manifest V2 change applied across Chrome regardless of who wrote an extension. Here's what happened and what else you can use for browser screenshots.

What Happened: Manifest V2 Deprecation

Manifest V3 is the current version of Chrome's extension platform; Google describes it as a step to improve the privacy, security and performance of extensions.

Google's timeline gives three dates: the Manifest V2 phase-out began on June 3, 2024; Manifest V2 was disabled for all users with Chrome 138 on July 24, 2025; and the remaining Manifest V2 extensions were removed from the Chrome Web Store on August 31, 2026.

Read Google's Manifest V2 support timeline.

Google's migration guide says that in Manifest V3 an extension's background code moves to a service worker that runs only when needed, the blocking version of the webRequest API is deprecated, and the ability to use remotely hosted code is removed.

For any specific extension, its Chrome Web Store listing and the maintainer's changelog show the current version.

If browser-tab capture is central to your work, the structural point worth taking from this is not about any one vendor: an extension's capabilities depend on a platform its authors don't control. See our Maxisnap vs Monosnap page for the desktop apps.

What This Means for You

If an extension you used for any of these workflows was turned off, you need another way to do them:

Capturing visible browser content — The most common use case. Taking a screenshot of what's currently displayed in a Chrome tab.
Full-page scrolling capture — Capturing an entire web page including content below the fold.
In-browser annotation — Annotating directly on top of web content before saving.
Quick sharing by link — Uploading captures and getting a shareable link.

Alternatives for Browser Screenshots

Option 1: Use a Desktop Screenshot Tool (Recommended)

A desktop screenshot tool that uses global hotkeys captures whatever is on your screen — including browser content — without depending on Chrome's extension APIs.

Maxisnap works this way. Press Ctrl+Alt+5 from any application (including Chrome) to capture a region of your screen. The annotation editor opens immediately. Your browser content is captured as pixels, so there's no dependency on Chrome's extension platform.

Download Maxisnap to capture browser pages from the desktop.

Option 2: Chrome's Built-In Developer Tools

Chrome's DevTools can take screenshots. Open DevTools (F12), press Ctrl+Shift+P to open the command menu, and type "screenshot." The command menu lists these screenshot commands:

Capture screenshot — Captures the visible viewport
Capture full size screenshot — Captures the entire page (scrolling capture)
Capture node screenshot — Captures a specific DOM element
Capture area screenshot — Captures a manually selected area

Google's Device Mode documentation, read in October 2026, describes capturing a screenshot and a full size screenshot from Device Mode's menu.

Option 3: Windows Built-In (Win + Shift + S)

Snipping Tool is Microsoft's screenshot and screen recording app included with Windows, with annotation tools and text extraction.

In Windows 11, press Win + Shift + S, select a region, and the capture goes to your clipboard. Microsoft’s guide describes the current features. See our complete keyboard shortcut guide.

Full-Page Scrolling Capture Without an Extension

Full-page scrolling capture is a common reason to use a browser extension. Some desktop tools include a scrolling-capture mode, and Chrome's DevTools has a full-page command.

Your options for full-page capture without an extension:

Chrome DevTools — "Capture full size screenshot" captures the whole page, including content that isn't visible in the viewport.
Firefox — Right-click the page and choose "Take Screenshot," then "Save full page."
Print to PDF — Ctrl+P > "Save as PDF" captures the full page. Not an image, but useful for documentation.

What Maxisnap Focuses On

Desktop screenshot tools like Maxisnap sit at the OS level. They capture pixels from the screen, independent of what application is displaying those pixels.

What that gives you in Maxisnap:

12 annotation tools
The Studio add-on enables upload to your own server via SFTP, S3, or HTTP
Custom keyboard shortcuts that work globally

Making the Switch

If you're transitioning from Monosnap's Chrome extension, here's a quick migration path:

Download Maxisnap and install the current 112 MB Windows build
Enable "Start with Windows" in settings so it's always available
Learn three hotkeys: Ctrl+Alt+5 (region), Ctrl+Alt+6 (fullscreen), Ctrl+Alt+7 (auto-upload)
Configure upload settings if you need shareable links (Settings > Upload)
Decide what to do with the Monosnap extension — check its Chrome Web Store listing for current status before removing it

Maxisnap is free to download and use, so there's no cost to try it.
