To add to the other anecdotes here: I've always used multiple browsers at the same time. On my local workstation I used Edge (used to be Chrome) for corporate and customer stuff, Firefox for everything else. Firefox runs faster with less headaches than the others, even with ADO, which is funny to me. When I encounter environments where only Chrome is available (e.g., jump box or application server in a customer's network) I have to deal with Chrome eating up too many resources. I often have to kill other users inactive sessions due to how much memory their Chrome process is using. I've seen it affect production performance due to it eating up so much memory. The only user app I've seen that sometimes uses more memory on those customer hosted systems is Oracle SQL Developer. Firefox is simply better for me. However, I won't argue with others on personal preference, hence why I don't just uninstall Chrome where I find it. Also I don't want those people to lose their bookmarks and browsing history.
