I feel like the bigger security concern here, if one needs to worry about it for their threat level that is more likely, is just like if someone knows your password, who could force me to unlock my phone via biometrics?

This was the majority of my experience as well. As a newer programmer, I'm more than happy to always know a better option. But if the way I'm looking to solve my problem is wrong, don't just give me Y, explain to me why it may not work how I think it will. Tell me about X and some pitfalls or reasoning for it not going to work, then recommend Y. Because if others only see the Y answer to my question about X, they'll probably just keep searching for a solution to X not knowing it may not work like I didn't know.
People have their gripes over the "big corporation" side of this but I also daily drive fedora KDE and I love it. My only complaint is 2 things.
-
Wireless shuts off after long periods of sleep. Suck if I'm torrenting my Linux isos.
-
Very rarely it'll freeze up and I need to hard restart.
Both of which could be a me issue. But besides that it's a beautiful, easily and highly customizable system. Highly reccomend as well.
I had tried to build one one time and got the ui down. As I started building the more complex arithmatic (chaining calculations) i realized how insanely complex it actually is. It made me realize how complex the most simple looking apps actually are.
So from what I understand, theres 2 common ways that browsers combat this. Someone add to or correct me if I'm wrong.
- Browsers such as Mull combat this by looking the same as every other browser. If you all look the same, it's hard to tell you apart. I believe this is why people recommend using default window size when using Tor.
Ex: Everyone wearing black pants and hoodies with the facemasks. Extremely hard to tell who is who.
- Browsers such as Brave randomize metadata that fingerprinting collects so that it's more difficult to piece it all together and build a trend/profile on someone.
Ex: look like a dog in one place, a cat in another place. They get data for a dog but that doesn't help build anything if the rest of the data is a cat, hamster, whatever. No way to piece it together to be useful.
In both my examples, there are caveats. Just because everyone dressed the same doesn't mean someone isn't taller or shorter, or skinnier or fatter. There can still be tells to help narrow down. Or a cat that barks like a dog suddenly is more linkable to a dog if that makes sense lol.
In other words it still depends user behavior that can contribute to the effectiveness of these tools.
EDIT: got distracted. To answer your question I don't think so. I think it's more about user behavior blending in or being randomized. I think the only thing an extension would be able to do is possibly randomize the data but I'm unsure of such an extension yet. These aren't the only options, these are just ones I've read about recently. Online behavior, browswr window size, and I'm sure so much more also goes into it. But every little bit helps and is better than nothing.
EDIT2: Added examples for each for clarity.
While the original comment has validity, I think it's important to know that a lot of the proton news you'll find is very "drop it immediately" biased.
I definitely think the news left a bad taste that's worth keeping an eye on, but I don't think it should eliminate them completely as an option. Especially for newer privacy advocates.
Edit: full disclosure for future readers, I may be biased as well since I do continue to use proton services and I love it. But I still try to look at both sides on things like this.

I feel this way too hard. I work with software and have a busy but chill job in the sense of no one really bothers me except ticket users/cool coworkers.
I get super distracted not only with rabbit holes but also trying to get organized.
Recently I've been trying to find ways to improve my productivity but its led me down hours or trying different apps/programs to try to better my work flow which in turn has hurt my work flow.
On top of that. The meds don't hit the same and I've found myself on my phone more.
I love my job too so it's not even that I don't wanna do the work lol.
