Other desktop Chromium browsers
Edge, Brave, Opera, and Vivaldi support Chrome Web Store extensions. This is general Chromium compatibility; individual SnapDiff features may vary by browser. Chrome is the reference browser for the full feature set.
Store availability
Chrome and Firefox listings become available independently. The buttons in Getting started show the current availability for each store. On a managed browser, your administrator may need to approve installation.
Each browser installation keeps its own capture library.
