Yes, this is the wanted behaviour and no, there is no option for that.
since last time I wrote, I’m really annoyed, that I can’t synchronize/manage Firefox’s favorites on my mobile.
I found XMarks addon for Firefox for Desktop but theres no equivalent for Android, which is able to make use of a self-chosen server.
My idea: make CALDAV (or a new app) a universal sync-APP using the WEBDAV protocol (if possible).
First stage: for chosen programs (e.g. browser, email) being able, to bring user data/profiles to a WEBDAV folder of choice, being managed or altered by desktop program, then applied to mobile device.
Second stage: universal use for individual choosen files/folders/data/profiles.
Is this a possible and realistic wish?
@herz_ag yes, thats possible with WebDAV I think. We’ve had a generalized WebDAV sync app in mind but right now we’re focusing on CalDAV/CardDAV (It is based on WebDAV but still very different). So it will not come in the near future Nevertheless the idea of such an app was in our minds for long time. So if not somebody else is making it maybe it will be a new app developed.
