LibreWolf is a great privacy oriented Browser for desktop. But there is no version for android or IOS . There are some like mull but they have their own problems. Mobile phones stay with us most of the day. So we need extra privacy for it.

It means that one malicious site can compromise your entire phone.
No it doesn’t? It means that a malicious site that can take over a browser process can also take over connections/accounts on websites that share the same browser process by bypassing mechanisms such as CORS.
This isolation mode is also pretty effective against things like side channel attacks, though real mitigations of those bugs require kernel/microcode updates.
To take over your phone, you need at least a sandbox escape exploit to break out of the browser app space, a privilege escalation exploit to get past selinux and other such protections, and even then the damage you can do is quite limited unless you’ve gained root access. Site isolation exploits can be used as the first step in a chain of exploits, but it’s not a very important part when it comes to preventing privileged RCE.

That sounds like the exposed attack surface is a lot more than just whatever sites are running under your Firefox process.
But what do I know, I’m not a developer of security-hardened Android forks, so I just have to pick which randos on the internet I choose to believe. When the developers of DivestOS and GrapheneOS both have lengthy write-ups on why chromium base browsers are significantly more secure, I’m going to believe them because I don’t have the low level technical knowledge to refute what they’re saying.
If a third part web browser “bypasses or cripples” OS sandboxing, then any app can. Seems like Graphene’s hardening isn’t very good for third party apps in that case.
Firefox doesn’t use Android’s API for sandboxing processes from each other, but that sandboxing isn’t what’s protecting your phone from getting taken over. There are many layers of security present within Android and process isolation for web content is just one of them.
I’m sure Graphene’s fork of Chrome is more secure than Firefox (especially with JIT turned off) but that doesn’t mean running Firefox presents any risk.
Android’s design is such that I should be able to install a random app and see no adverse effects other than battery drain/high network load without clicking through dozens of security prompts. If that’s not the case, there’s a vulnerability in the Android layer that needs patching, such as the Qualcomm vulnerability that was released recently.
With open security holes like that, not even Chrome’s site isolation is going to protect you
Right, so if Gecko based browsers can cause that kind of security concern on Graphene, what does that mean for people using Android ROMs that are not hardened, or, OEM variants that do not receive regular security updates?
Any app installed by a user that takes advantage of an active and unpatched CVE, can do all sorts of actions to compromise an entire phone, or critical parts of it. Are you saying that’s not the case?
The difference between a compromised app, and a browser, is that even a “safe” Firefox install is used to browse a near infinite possibility of websites, any number of which might be running an active campaign targeting unpatched Android vulnerabilities.
It sounds like you’re saying that despite Firefox Geckos significantly larger attack surface, the fact that Chromium doesn’t eliminate all risk, means there’s no difference.

It’s like you’re arguing because you like to argue, and can’t admit that you’re wrong. So you keep finding new ways to qualify your response in the hopes that I forget what this is even about.
Chromium is significantly more secure than Firefox Gecko on Android. That is according to the developers of probably the two most well regarded hardened Android ROMs.
One of which, Graphene, even advises completely avoiding Gecko based browsers.
Which is what I said in my original comment, well, the part about relative security.
You’ve also claimed that at most, a malicious android application can only harm battery life and cause network issues, which is objectively false. I’m honestly kind of confused why you even said that, but whatever.
I never said no one should use Firefox based browsers on Android, I just said they weren’t as secure and that user should understand the risks associated with them.
But what I’m most confused and perplexed by, is your insistence that only high risk individuals should be concerned with using a browser that comes with, at minimum, double the attack service they’re exposed to when browsing the web.
Again, that is per the GrapheneOS wiki/FAQ.
I mean, we’re not talking about some hardcore and incredibly inconvenient levels of unnecessary OPSEC for the sake of OPSEC, we’re talking about a browser.
Tell you what, if you post a link to your GitHub showing me the hardened Android ROM that you develop, or heavily contribute to, I would be happy to revise my opinion on your credibility versus those developers.
