It took them SO LONG to get back to this point. They gutted the extensions with the redesign a while back. Only allowed approved extensions(which I understand since a lot of desktop extension ui just doesnt work on android and many extensions are broken), but then they kinda just stopped. They added a convoluted method of creating an account and whitelisting extensions on the account if you use nightly, but it was a hassle to use and it's been years since even that was introduced.
And I mean, for normies it might be OK, but why not add a toggle that allows me to install whatever I want. If they don't work I'll just have to uninstall the again. It's not like it's gonna break my browser
I last used a chromium based browser more than 5 years ago. Recently I bought myself a tablet and had to make the difficult decision to switch to the kiwi browser there just because Mozilla can't be bothered to include tabs for their tablet layout.
