I don’t use Google Chrome, but there are plenty of other chromium-based browsers out there.
This isn’t the first time I’ve run up against technical shortcomings of Firefox, either. I used to frequent a site which made use of the CSS class column-span. Chrome added full support for that class in early 2016. I was probably accessing this site from about late 2016 until about 2018 or so. Firefox didn’t support column-span until December 2019. The whole time I used the site, Firefox simply could not render it in a usable way.
I’ve said for a long time that we’d be better off if Firefox switched to Chromium. They clearly don’t have the resources to keep up with the rapid pace of change on the web. 5 years and they still don’t support a browser feature that Google got out in a out 1 year and I think Edge got it done in 2 or 3 (and unsurprisingly, Apple has it ready day 1, though that’s an unfair comparison for obvious reasons). Three and a half years behind other browsers in getting out a CSS feature that’s being used live on the web already.
If they based their browser on Chromium, there would be so much less work for them to do. They’d have to spend some effort maintaining features Google has decided to drop, like Manifest V2, but they wouldn’t be alone in that effort, since they can pool resources with the likes of Vivaldi and Brave, and maybe even Microsoft in some cases. So I’m the end a much higher percentage of their resources could be spent developing features that differentiate them and help maintain them as a great privacy-focused browser, instead of merely keeping up on the treadmill of platform change.
