As I mentioned, I regularly (read: on daily basis) use four other browsers: Chrome, Firefox, Maxthon and Opera. I want to stay always automatically signed in to multiple Azure AD and Microsoft accounts, Edge being signed in to main AAD and MS accounts, four other browsers to rest of them. In fact, as the new Search function shows the five most used non-default applications on top, you can see that in my case three of those five are other browsers, in addition to my default Edge:
I am a very experienced user of Chrome, Firefox, Maxthon and Opera.
I have not stopped using extensions or add-ons because I use Edge. Even before Edge, when my main browsers were Chrome and Maxthon, I have never seen a reason to use any extensions. Of course there are some exceptions, I for instance use a short URL extension in Chrome to get some long URLs I want to post changed to my own custom short URL, to give an example here's a link to your post I am quoting:
w10g.eu/s
You saying I do not know other browsers enough is simply not true. Was it yesterday or day before when you wrongly accused me about saying all not using Edge are wrong? Now it looks to me that you do your best to tell I am wrong because I love Edge.
I repeat: I am very experienced user of Chrome, Firefox, Maxthon and Opera. Because I know them well, know how resource hungry they are, and because they lose in comparison to Edge in every aspect, I love and use Edge.
Your mileage may vary.
