If Firefox could make their Dev tools as good as Chrome's, I would switch immediately.

Firefox is already valuable for browsing on mobile phone, where there is not much space on screen to have Dev console anyway. I recommend trying Firefox Mobile

I would actually really like an answer to this question, I’ve often thought about it!

Huh, I thought the original was a sarcastic question. In that case, let me explain: I keep a browser window open at all times. It is never full screen, because if it were full screen I wouldn't be able to see multiple windows at the same time. I keep my browsing window as close to 1024x768 as possible. In 2019, a lot of websites can't handle a browser window using a mere 75% of the laptop screen, so they either rende…

Thanks for the answer. I just thought people usually kept their windows at full screen, but reading all the replies perhaps I am the outlier here!

Why can't the ad industry just accept that there are some people out there who don't want to see ads and wouldn't click on one to begin with? Then they can honor Do Not Track and those who choose to work in adtech can start working on things that are more productive to their business.

Apps need it to determine where to place elements. If it wasn't you would still be able to reverse engineer it by sticking elements outside the viewport and seeing if they're hidden or not. Turns out anonymity is super freaking hard. :-/

Some would take enhanced privacy over properly-functioning sites. I wonder how broken sites would appear if the browser simply lied about such things.

People with that preference usually just turn off javascript.

But I've already got code in my xmonad.hs that clamps firefox windows to common monitor sizes?

It's truly unfortunate that browsers just punted on security, dumping endless amounts of sensitive information into a purported sandbox. Why bother developing something with a secure mindset to begin with, when you can just band-aid on patches later?! It's the sendmail/ActiveX philosophy all over again, only now with network effects.

I'm guessing they would lose their financing from Google by adding UBlock.

I don't know the terms but surely there are enough parties willing to pay them- MS would love to shoot with gun on fx shoulders. The engineering effort required to implement this feature is better spent in doing useful things.

That's just a bet, I doubt Mozilla is willing to blast google on the chance there is someone willing to pay them, they'd probably rather have a sound financial cushion from non-google before going after google.

That might have worked if Microsoft hadn't enabled Do Not Track by default.

Every time there's something about online privacy with browsers, it's mostly Firefox or Safari. I wondered if Chrome had resisting fingerprinting on its radar (guessing that it wouldn't be in Google's interests to add any feature that would thwart profiling users online), and I found this [1] confirming my guess (emphasis mine): > Since we don't believe it's feasible to provide some mode of Chrome that can truly prev…

Here's a good comparison: Android Chrome's user agent:

Mozilla/5.0 (Linux; Android 6.0.1; SM-G928F Build/MMB29K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Mobile Safari/537.36

Versus Android Firefox's user agent: Mozilla/5.0 (Android 9; Mobile; rv:66.0) Gecko/66.0 Firefox/66.0

Note how the Chrome browser announces your phone model and software build version to the world.

With regional models with carrier customised software builds, simply the user agent can be used to fingerprint a user.
