The problem isn't Edge in itself. It is good if there are many browsers. But when Javascript became more than just a play thing, all of a sudden browser slowly moved to chromium as an engine. There used to be Opera, IE, Edge, Firefox, Safari and Chrome with each their own browser engine. Now there is only Chromium/Blink, Safari and Firefox left. Google is way too powerful with their marketshare. They constantly try to implement features that are bad for users.
The problem is that it will take ages for them to get any adoption in a new browser. Firefox used to be a big player and then chrome came along. Now most of the people don't even try Firefox anymore. I still hear a lot of "Firefox is slow" sentiment even though it isn't.
I've started using Firefox at work, too. Unfortunately, I still have to use a lot of the Google sites at work, but they all work flawlessly within Firefox and uBO.
I also use it at work and it really sucks. I also have Chrome on my work computer, but for everything work-related I have to use Edge. Like E-Mails and Sharepoint-Stuff. Edge's startup time is at least 4 times Chrome's startup time. Sites load extremely slow directly compared to Chrome. No Adblockers. I really don't like this.
ublock origin is published to the addon 'store' for edge and opera, in addition to mozilla's (firefox and thunderbird) and chrome. links to all are on the repo's main page https://github.com/gorhill/uBlock

That's a decision your IT department made. I use Firefox with all of that at work.
Can confirm. I also have to use Sharepoint with certain groups, and it works just fine. The web interface for Outlook works just fine as well.
I also have to use Google at work, and everything I've used works within Firefox.
I think it's important to point this out because a lot of people seem to be laboring under the misconception that the sites they use will break in Firefox. The only sites I've found that don't work are things like Bing AI, which work fine if you switch the user agent header.
