That kid is superior

One thing I've been annoyed with after switching to Firefox is the iffy password manager performance. It's so common for it not to remember a password that it should, or, weirdly, for it to only remember the password once I've typed the whole username in and hit tab.

Functionality wise, chrome is better than Firefox but it's bad when it comes to privacy and ads

Always gonna note too that Google Chrome (and chromium + derivatives to a lesser extent) kneecaps adblock plugins so that up to 50% fewer ad domains are blocked, blocklists are out of date, many in-page ads can't be caught, it's slower, and invisible trackers can bypass it.

This might be known already, but I bet that Microsoft decided to switch Edge to Chromium instead of forking Gecko/Firefox because Google either bribed them or threatened to lower Microsoft sites' ranks in search results.

Otherwise why would MS use a web browser controlled by one of their very few competitors?

Edit: maybe they were enthralled by the promise of using Proton/Chromium based "desktop applications" (which just contain an entire Chromium browser in their install directory) to cheaply create apps that people are forced to use in their jobs, like Teams. Which is still awful even after they made it a full UWP desktop app. Like Skype already was.
