I want my passwords, bookmarks, tabs and history to synchronize with my iPad in an end-to-end-encrypted fashion. Are there currently any possibilities for this with Firefox? The current unsatisfactory options I know of are: === 1. Bookmarks On The Go === An app mentioned by a previous question. Apparently developed by a Mozilla developer based on Firefox Sync's code, so it should be trustable. Doesn't seem to cover passwords and even if it did it wouldn't be able to provide autofill. === 2. Dolphin, Mercury browsers for iOS === Dolphin used to provide synchronization with Firefox sync, but currently both Dolphin and Mercury use Desktop addons for synchronization. I couldn't find any information regarding encryption, but I'm pretty certain that these addon approaches undermine Firefox Sync's end-to-end encryption. For dolphin connect I could find a review saying that you have to specify a separate password for password synchronization, but overall the zero-knowledge approach is still undermined. === 3. iCloud addon === Basically the same issues as with (2) and no password synchronization.
