I’ve been spending a lot of time on mobile due to medical reasons, and I can’t seem to find a straight answer as to which mobile browser is best; I use FF on my PC and currently on mobile as well, but I’m seeing people call Bromite better, and others recommend Mull or Fennec. I (unfortunately) haven’t been able to jailbreak my phone or anything out of fear of bricking my sole means of emergency contact, so I have a Galaxy S10 with as many bloatware features disabled as possible, but not any OS installed or anything, as much as I’d love to. I’m not as tech savvy as I’d like to be.

Apologies for the wall of text. I just really want to know what to use.

Bromite is chromium based and has site isolation wheras mull doesn’t have process isolation. Both are hardened browsers and are very good for privacy. If your threat model requires site isolation go for bromite but if you don’t need it, you can go for mull. I think mull is enough for my threat model and I really like its ad and tracker blocking and addon capabilities. You can add any addon with a customized addon collection.

Firefox has site isolation since a good while now, these are GrapheneOS community lies that Bromite has exclusive rights over it. These lies can be traced back to madaidan, and were debunked long ago: https://old.reddit.com/r/netsec/comments/i80uki/_/g162g4r/?context=3

Firefox has Tor Project features like First Party Isolation and anti fingerprinting which is unmatched by any Google Chrome or Blink/WebKit variants. Therefore, for site isolation, one must choose Firefox. Bromite and Google Chrome have lots of issues like WebRTC leaks.

Firefox doesn’t have per-site process isolation. That info is from the dev of mull.

I’m not sure what info to take from that linked comment, sorry. I didn’t refer to madaidan or grapheneos.

WebRTC is obviously only a problem if you use it. I think I’ve never used WebRTC in an android browser.

The site isolation claims for the past 3 years are made by madaidan, and not u/subzer0carnage on reddit. To debunk your very own claim, let me cite the developer of Mull and DivestOS himself, from reddit, from 3 weeks ago.

“Site Isolation” on its own is nonsense that people need to stop parroting. When it comes to browsers you have per-site PROCESS and DATA isolation. On desktop:

  • Chromium by default has per-site process isolation
  • Chromium by default has no per-site data isolation
  • Firefox by default has per-site process isolation
  • Firefox by default has some per-site data isolation
    • In private browsing mode has strong per-site data isolation On Android:
  • Chromium by default has per-site process isolation
  • Chromium by default has no per-site data isolation
    • Bromite and Mulch enables strong per-site data isolation
  • Firefox has no per-site process isolation or Android isolateProcess usage
    • This is the big issue people usually mean
  • Firefox by default has little per-site data isolation
    • Mull enables strong per-site data isolation Useful sites:
  • https://divestos.org/index.php?page=browsers
  • https://privacytests.org/ Also because it isn’t obvious, Mull and Mulch are my projects.

Thx for the clarification. Maybe there was just a misunderstanding. I wrote site isolation but meant per-site process isolation in the first comment but added it in the following comment.

As an alternative to Bromite there is Kiwi which is a good balance between privacy and usability.

Be careful because Kiwi in the latest release insert a lot of tracking: https://reports.exodus-privacy.eu.org/it/reports/com.kiwibrowser.browser/latest/

  • Facebook ADS
  • Google AdMob
  • Google Firebase

Doesn’t fission offer site isolation for firefox on android? It’s disabled by default but you can turn it on with about:config

I don’t think that enabling it does anything

Btw on android it’s called rooting not jailbraking. I highly advise against rooting your android as this can introduce security risks. Indtalling another os like grapheneos does not requiere root access.
