I use firefox as my primary browser, but I have recently ran into issues with several sites that I need to use. Whenever I contact support, they tell me their site requires Chrome.
As it is, I have a Winblows box for gaming only that I put Chrome on, but one day, I am going to be remote and needing Chrome. I don't want google's tentacles on my work laptop, but am starting to worry that I have no choice...
If you absolutely must use Chromium you can use Brave instead. It doesn't solve the extensions issue discussed here but at least it cuts out most of the Google garbage.
Netflix limits video quality on Firefox although you can trick it with an extension. Then there is the fact that hardware accelerated decoding for Linux/X11 hasn't hit yet.
Anyway one valid solution is to add one or more app shortcuts that effectively run chrome/chromium --app=url and collectively treat these chrome specific apps as such. Instead of opening a new tab just click the icon on your bar.
Ironic. Back in the days when IE was king, we thought that all that's needed for a truly open web is open standards. Now Google has demonstrated how you can have open standards, but still create and maintain a monoculture around them, simply by evolving them so fast that any competition can't keep up.
The builds themselves may potentially be insecure, but they're rather popular among the security-conscious target audience, so I hope someone would notice if they go bad.
