Yab 0.47.6
Yab no longer opens a second copy of itself and quits shortly after launch, saved emails fill forms on Chromium tabs again, and the full-screen top bar no longer flickers.
Added
Extensions
Install an extension from a .crx file or a folder: choose it or drop it on the Extensions page; its signature is checked first.
Fixed
Launch
Yab always starts and restarts as the app in your Applications folder, so it no longer opens a second copy of itself in the Dock and then quits.
Crashes
When Yab closes unexpectedly, its report goes out early at the next start, if you allow crash reports, so it can be fixed.
Autofill
Picking a saved email under a field fills it on Chromium tabs too, on sign-in pages and checkouts such as Best Buy.
Full Screen
In full screen the top bar slides in once with the menu bar when you reach the top, without flickering or moving the page.
Developer Tools
Export HAR and Import HAR open the save and open panels again.
