App: BrowserNow
Developer: Robert Anderson
Genres: Utilities

Just click the BrowserNow status item, select which browser you want to use and confirm the change with the macOS system dialog. All websites will open with that browser from now on, exactly the same as changing it in System Preferences. Your browsers are listed alphabetically and you can use ⌘1-9 to quickly select them without leaving your keyboard.

Release notes:
Bug fixes and improv... nope, there are actually two new features:

⏺ Automatic icon detection, BrowserNow will use your mac's existing icon in the menu bar, even if you have manually changed the icon in "Get Info"
⏺ Added keyboard shortcuts so you can use ⌘1-9 to select browsers (they're in alphabetical order for consistency).

Other bits:

⏺ Because native icons are being used, the app got ever so slightly smaller, because the previous icons were embedded in there.
⏺ Use ⌘Q to quick quit BrowserNow
⏺ The menu is a bit bigger (the icons that macOS provides are bigger and I kinda liked the look)
