Or you can use the "double tap the dots menu" trick.
You might like it, though. I've used Brave's mobile sync and it works for bookmarks across devices quite well. It's surprisingly simple to set up, too. I don't fret much about forgetting whether I opened a tab on my phone or desktop if I remember to bookmark it.
That said, I still use KDE connect to send links to my primary Firefox instance and vice-versa, but the bookmark sync is in some ways more convenient. I'd imagine they'll eventually synchronize more things, like tabs.
The same happens when some sites require Chrome to work, blocking all the rest. In 2019 it's unacceptable
Because it's 100% just a missing feature in Firefox mobile, there's nothing website developers should add to "make it work" on it.
Future monetization: that was actually an incentive for me. Having been in the belly of the beast on ad-tech I'm cheering the new ad model Brave proposes for the industry.
If you're not aware how messed up the industry currently is, keep an eye on Ad Fraud Historian on Twitter: https://twitter.com/acfou.
On the crypto front, proposing ideas like staking / slashing on their extension store for extension authors is also very interesting: https://twitter.com/BrendanEich/status/1143630584310202369
The new browser wars are certainly spurring innovation again: good for everyone regardless of personal browser preferences.
OS certificate stores often come with the political baggage of the OS manufacturer. When a Chinese Gov't CA was found to have engaged in fraudulent behavior [0] Google and Firefox were quick to revoke/remove the CA cert from their products. Apple and Microsoft did not do the same, likely because they do not want to upset the Chinese Gov't. (IIRC Iphone users cannot even manually revoke CA's on their own phones.)

Using the OS secure-store should be a preference option. The folks who don't want to use the "political baggage" of the OS manufacturer - as you put it - can continue to use their pristine gardens.
It would be nice however if Firefox had an option to use the OS store, including devices like yubikey.
