Not anymore, If you want a firefox based browser, go with mullvadbrowser, Tor or Librewolf, all with canvas blocker set to the proactive? protection profile...I think it's called.
Nope. Afaik, there is still no legal precedent set that you must make your publicly available website usable on more than one browser suite. Which is ludicrous, because Google has quietly been trying to make Chrome the only option.
When I say that Edge is equivalent to Chrome, I don't mean that Edge is exactly Chrome It's not what I said and it's not what I meant. I mean that for all intents and purposes you can use edge for anything you want to use Chrome for. Major differentiation is that you're giving all of your data to Microsoft in lieu of Google. And you could look at all the other chromium base browsers and say yeah you could do the same thing with those but in this case we have a business user. There's businesses are probably already running Microsoft networks. They might very well already have Microsoft SSO. Edge is going to have all kinds of great tie-ins to active directory policy. So secops/it is going to try to force you to use Edge, instead of say Firefox with a barely have any control over or maybe brave where you're going to try TOR or IPFS and just basically be a stain on their HIDS board.
I’ve been at companies that did that too, historically, but it seems like a solved problem. My current company does UI testing only through headless browsers and it seems to work
These terms are absolutely meaningless. Browsers like all Chromium forks and Firefox add new CSS, HTML and JS features on a almost monthly basis. Safari then usually is takes a year more to implement them. And for the past few years Chrome has usually been adding new stuff the fastest, then Firefox a bit later and then Apple adds them after a year, but only if they don't threaten the native Apps on iOS because of AppStore money.
