Firefox is more secure than Chrome, but it's not very secure. The sad thing is that it used to be more secure and Mozilla deliberately weakened their security.
If I understand correctly, you're saying that we should be careful about saving passwords in Firefox if we could be the target of a National Security Letter from the US. The attack would be detectable, so it cannot be used very often (and they would need a really good excuse for doing so).
By contrast, Google takes all our data and can do whatever they want with it, without a warrant/NSL?
I have no idea why so many downvotes. Can anyone disagree that a system in which Mozilla is able to decrypt user data is insecure?
One note: the attack is not necessarily detectable, unless you are in the practice of verifying the JavaScript you receive for each page. If there were some public registry of hashed versions of Mozilla-served JavaScript, it would be detectable.
Also, you need not worry only about the U.S. government, but also about any government which can compel Mozilla to act, and any government which can compel an employee of Mozilla to act, and finally any employees at Mozilla with access. And also you need to worry about bugs in Mozilla's JavaScript: since they did not design a system in which they can't know your password (which is the key to all your secrets), an implementation error might send them your password (and thus allow them to decrypt all your secrets).
People get annoyed of being told x-y-z is not secure, while not being offered any practical solution, especially if the risk/probability of attack is low.
(I'm assuming Firefox has a good reason for working the way it does, but I guess the first step would be to have more documentation about that.)
Which can themselves be compromised. The old Firefox Sync protocol was immune to remote compromise, completely and totally.
> People get annoyed of being told x-y-z is not secure, while not being offered any practical solution
I agree: the problem is that there was a practical solution: just keep the old Sync protocol.
> I'm assuming Firefox has a good reason for working the way it does
The short version is that people wanted to be able to only have one device and still get at their data, and Mozilla didn't want to confuse them by separating their account passwords and their sync passwords. Never mind that combining them has results in a wholesale loss of security.
but i think i'll stick with 56 as my default browser for a little longer since quantum breaks some great legacy add-ons:
* NoScript -- control script execution
* RequestPolicy (and its variants) -- control content requests
* Blend In -- use the most common user agent string
ublock origin can somewhat replace the first two (although i think its UI could use some improvement) but the latter one and a few more that i use don't have direct equivalents (yet).It won't be quite full-featured yet, though. He's planning that for Firefox 59, which will be the next Extended Support Release and what Tor Browser will be based on (which needs NoScript).
There's a handful of compatible user-agent switchers already...
It'll set the user agent to the same as the Tor browser, Firefox 52.
I suppose it has benefit now with Android, and multiple devices, but Google, and Youtube both started saving searches long before the release of Chrome.
Quite terrible.
If you are logged in you Google account, every Google search will end up in your Google history. It doesn't matter if you search from Chrome's omnibox, google.com or Firefox's search bar.
Does Chrome also uploads search made with other search engines? That would be a bit more worrisome. Though considering that Firefox saves your history in your "Firefox Sync" account, I wouldn't be surprised if Google did the same.
Chrome is specifically designed to do the opposite: Google explicitly states that when you sign into Chrome, "your experience in other Google products is personalized by including your Chrome history with your Web & App Activity." (https://support.google.com/chrome/answer/185277)
And interestingly, you could have a page showing your search history with Firefox sync just like with Google. Just because a page shows you private data doesn't mean someone else has access to it, and the more common opposite is also true.
(Note, that while the password and key derived from it never normally leave the brwser, the login page is served from the network. So, you trust Mozilla's servers to not get hacked and serve you insecure login page.)
The system also has a notion of "class A" storage, where Mozilla knows the key (called kA), but AFAIK nothing ever used that. Maybe its already gone.
Oh, the device names (and types - like desktop vs android) are not encrypted. Probably because of attempts to add push updates (normally, sync is just polling for updates). And the profile data too (not a part of Sync at all - its Accounts).
Google has optional client-side (also, E2E) encryption, for some types of the data (e.g. passwords and autofill data). One has to opt in explicitly. When opted in, data is encrypted with a key that's is derived form a passphrase you provide (and sync implementations would error and ask you for the passphrase). I'm not sure, but IIRC protocol has provisions that allow to not encrypt some data at client's (= Chrome's) discretion, as the encrypted flag is set per-object. I'm not aware if this is used or not - was a very long while since I've looked at their sync server implementation.
That said, for E2E encryption both system have feature parity, but Mozilla's one has it by design and Google's one only as an opt-in.

"When you sign in to Chrome, your info is saved to your Google Account so you can get it whenever you need it."
It is literally the first sentence. I also support some of the various EU privacy initiatives but I don't support them because I think users should be militantly ignorant about what they're doing.
I don't remember Google ever warning me specifically that this was happening in the background, and after I checked https://myactivity.google.com/myactivity and noticed it was doing that, I was so furious that I deleted all the data Google kept on me there, and paused all tracking in the Activity Controls page. I also stopped signing in to the Google account in Chrome.
This is why I'm a big supporter of EU's "explicit consent" idea. I should be knowing stuff like that without having to read a 5-page privacy policy that's often hidden somewhere on the Help page.
Speaking of Firefox, version 57 also makes it easier to enable Tracking Protection in settings now (before you had to switch to the private windows to benefit from it, although you could make it so that FF always opened private windows by default).

You can download FF57 from their FTP servers (they published it today), if you can't wait for the auto-update tomorrow:
