I have no favorite or dislike for any browser. I use X 'browser' which satisfies my need and increases my efficiency.
Along with required extensions, I have found FireFox fulfilling my current need.
I began with Netscape, Ie, Chrome and FireFox. I have tried Opera, Vivaldi (now) and many other browsers.
My first chance of using FireFox came when I was using Chrome and Gmail was introduced. I need a keyboard shortcut to delete a message quickly. I found Greasemonkey and script to delete and also label. I myself made script for removing label and shared in that forum.
Now all is available in GMail itself, but that incident showed me the power of extension in FireFox. I have posted above my current extensions. I may post in details what benefit I get from them and why I can not live without them, even if the browser itself is more powerful otherwise.
