Update supported browsers work with JXA(applescript) e.g Yandex, Vivaldi and variants of Safari and Chrome.
Change use app's default icon.
Change JXA app activation with file path instead of app name.
Remove activation effect

Caveats

It works OOB with Safari, Chrome, or Chromium based browser which supports applescript well. If it's not working, just add your browser name to SUPPORTED_BROWSER and CHROMIUM section in the tabs.js for jxa and constants.js for node

Install browser extension
Firefox: https://addons.mozilla.org/en-US/firefox/addon/alfred-tabs-ff/
Opera: Awaiting moderation, install it manually.
Opera: It's easy. Go to Extensions page. Enable Developer Mode - Load Unpacked Extension... and locate /usr/local/lib/node_modules/alfred-tabs-improved/messaging/addon-opera/, press Select button.
(Default node global path: /usr/local/lib/node_modules/)

somewhat messy and basic
installation size is bigger than original one. because of uws, it takes about 10 MB alone.
Firefox rises again, after Quantum launched. (but I'll stick with Chrome)

Epilogue

Asynchronous!??? had fun with node and js. (I don't know it well)
Who cares? I hope this helpful to you.
