Seriously. I thought we had enough Internet browsers. I use 3 on a regular basis. I use Chrome as my main working browser. I login using my work ID. I use Firefox to access client related programs like our CRM (Solve 360), Google Analytics, and Google AdWords. Up until today I was using Microsoft Edge to log into my personal email.
1. Fast loading time
It's fast. Enough said.
This feature is loaded from the left side toolbar. Essentially, you can open up another "tab" and view another website. I'm often looking at 2 different websites or programs at the same time. In the screenshot below you can see that I have opened up our website in the panel and I'm also looking at our tool, SEO-Browser on the right side. This is much simpler to setup than opening a new tab and resizing everything to fit on the screen. There is no "search" capability in the panel - you have to know the exact URL of the website you want to look at which feels strange. And you can't pop the panel out to be a tab or a new window. That would be nice.
