I don't know that I even trust openssl anymore. I used to run chromium, but got tired of it passing so much information back to google, so I went back to firefox. What I run is not an ideal solution. I'm open to other suggestions. I used to love chrome, but got tired of google spying. And yes, you have to turn off features in firefox to avoid similar spying behavior, but it can be done without maintaining your own version of the source code.
Chromium doesn't have 'spying' code that's not optional. It supports more Google services than Firefox and uses more of them out-of-the-box since it's the basis of the browser Google uses to promote themselves. Firefox is picking up support for non-Google proprietary services over time anyway so it'll probably end up with more in the end.
User security is certainly much, much lower on Firefox's priority list. They don't even enable ASLR yet, let alone robust sandboxing and advanced exploit mitigations throughout the browser. Mozilla ends up taking the same anti-user positions on issues like DRM after pretending that they're different. I can't think of one issue where they've taken the high road compared to Chromium. At least you know what you're getting with Google: profit-oriented corporation. Mozilla may not be accountable to shareholders, but they're even less concerned about the users. Google will reverse course during a PR disaster... Mozilla will just dig in and stonewall.
For just one of many examples, look at the difference in the handling of the WebRTC IP leak:
Oh, and the developer making the calls at Mozilla on this WebRTC privacy disaster developed the backdoored random number generation standard with the NSA. Mozilla isn't interested in commenting on this at all, as is usually the case (all discussion about it has been shut down).
Google would have fired this guy ASAP because it's not in their self-interest to make themselves look bad. Mozilla just coasts by on a naive, trusting community as they always do... and yet of their prominent developers think you should be groveling at their feet for all the good they've done for FOSS.
