Would be helpful if the Firefox store made it clear if extensions support this. Also, why do some first-party extensions ignore it??
Also: there are other things sync still misses, like config.
IMO this is quite unfortunate, and is mostly a consequence of the implementation of extension storage sync being done separately from the rest of sync (which in retrospect was a mistake, but at the time that wasn't clear). Also, the limits are copy-pasted directly from the limits chrome places on sync, so it's possible there are compatibility concerns as well.
For config (assuming you mean prefs in about:config), you can add your own prefs to be synced with about:config. If you add a new boolean pref with a value of true using the pattern `services.sync.prefs.sync.<pref you want to sync here>` it will be synced. e.g. to sync `browser.foo.bar` you'd create `services.sync.prefs.sync.browser.foo.bar`.
Disclaimer: I work on Firefox sync.
[0]: In the future this may be more complex, and you may need to flip an additional pref to get this behavior for non-default prefs.
And userChrome/Content.css... looks like I’ll need to dropbox those.
Editing css was essential to make the switch from Vivaldi to FF - yesterday! Getting TreestyleTab et al. to feel like Vivaldi with vertical tabs required some fiddling: sidebar without menu, hidden top tabs, darker text color, etc.
In any case, it’s my new daily driver and I'm quite satisfied so far. Even set DDG as the default while at it.
I just assumed that this behavior would apply to everything once I turned sync on, and then was disappointed when it didn’t work. I had no idea it was an optional feature.
I guess it doesn’t fit the key-value paradigm, but this feature would be a lot more discoverable if there was a “sync?” Attribute next to each about:config item.

Alternatively every about:config option has a corresponding option that enables sync for it. But that gets messy with many options.

That's exactly what I did, except I just forked the ghacks-user.js user.js file with the changes I needed
I then made a desktop branch, and an android branch.
https://github.com/dngray/ghacks-user.js/tree/fx-desktop
https://github.com/dngray/ghacks-user.js/tree/fx-android
The main reason I'll never use Chrome is because on Android that means no extensions whatsoever, meaning I'd have to give up uBlock and uMatrix. It's also why I wouldn't buy an iPhone (Firefox on iOS isn't allowed to have extensions).
A user.js file can be deployed on Android https://github.com/ghacksuserjs/ghacks-user.js/wiki/1.6-Fire... (I use the non-rooted instructions).
On my desktop I have it hooked in with my bootstrap script. I use Yadm https://yadm.io/
