It's me! I've been a very naughty lady.

Me, but because I need chromium for work and refuse to use Chrome. Firefox for everyday browsing.

I know one person :'(

i don’t think i’ve ever used a microsoft product that didn’t feel like it was still in beta

Mozilla's "Multi-Account Containers" extension on Firefox does a much better job at the multiple profiles feature you've described.

It's like they want to drive away the experienced users who don't need their hands held and rarely need support to focus on the part of the market that will still find ways to break things no matter how much they dumb it down.

You can do that in Chrome too, if you have multiple chrome profiles right clicking on links give you the option to open it in a different profiles window

One very nice feature is that when you use multiple profiles, you can specify in which of those external links open in.

is this similar to Firefox containers? dunno why mozzila makes it as a plugin and hasn't bundled it in yet as a standard feature, literally can't live without it.

Use different user accounts. That provides you with very stronger isolation and separation of concerns, with the bonus that you won't be exposed to their crap.

you can use a work sandbox in firefox to keep it seperate

Edge is just Chromium. When they retired IE they switched. It might still work better because it's the default supposedly built to work with their products so their tweaks should help. But it is Teams and they've been doing a lot more updates lately. Did you update to the new version of Teams they've been pushing? It's bad and it's performance is bad, so that can cause issues.

Heh reminds me when I was doing web development back in the day and had IE running on Linux. It actually made more sense to test compatibility with IE by running it through wine on Linux than actually doing it on Windows because I could have multiple versions of IE installed at the same time.
