Firefox for Android Community Forum

Hi,

Super cool site-isolation is now rolled out for Firefox Android!

I was checking the 'about:memory' and 'about:process' info pages and noted that there only seems two different processes for all tabs. As Firefox desktop achieves site-isolation via different processes per tab I was wondering if on my android device its correctly enabled. Can you elaborate if this is intended and how the site-isolation on android works?

Thanks!

I need no one can't mirroring my phone and hak my device.no one can get my browsing data. I need my browser safe and private the most ..

I have zero interest in this nonsense malware being added, especially with their terrible reputation for security

I'm giving my old Galaxy S7 to a friend, I've got her a prepaid SIM and put it into the S7 (my own SIM has gone into a new S22). I've managed to set up the S7 to sync with her data via DAVx5, Thunderbird was easy to set up thanks to the QR-Code export, and various other things worked as expected.

BUT she uses firefox sync, and so do I. I deinstalled firefox on the S7, and reinstalled it, and changed to her sync account - but all my own personal data (bookmarks, chronology etc) are still there. That's not only really annoying, but also a breach of my private sphere.

Google KI tells me to give her sync account a new password, before doing that decoupling from sync on all used devices; we have five, so that would be a real pain. The only other option I see is a factory reset and then repeat all the work setting up the S7.

So what I'm asking for is an option when firefox is deinstalled, or as an extra option in the settings, to delete all stored personal data.

Is firefox safe? How is it's privacy compared to chrome and edge? Is firefox at par with chrome and edge? In terms of popularity compared to chrome and edge -- how does firefox stand?

My browser has been infected with Porto sites that I have trying to remove, but they just returned through emails and web posts How do I permanently remove and block them?

Is there any way to disable or bypass the safe browsing filter in Firefox android? I'm trying to access a site that has been blocked as a "deceptive site" and there seems to be no way to ignore or completely disable the warning.

Прошу припинити підтримку Firefox на Android 8/9.

Ці версії ОС більше не підтримуються та не отримують оновлень безпеки. Надання підтримки старим версіям створює ризики для користувачів (шкідливе ПЗ, викрадення даних, експлойти).

Це питання безпеки та відповідальності розробника, а не сумісності.

I keep getting devastating messages from Google warning me that my Android is corrupted with Virus's! If I don't allow them to CLEAN it, I may be REMOVED FROM THEIR SITE! This is not verbatim, but close! I'm an 85 year old disabled widow & need my phone badly! I'm scared they will remove me! HELP!

Long story short, I want to view a link from a QR code, but I don't want to open it in Firefox itself. I fear that doing so would expose me to scams. So, I want the link prompt (deny or allow) to allow me to copy the url, so that I can paste it in a different browser.

So I have been hacked by somebody I'm pretty sure and I think you guys have found the link between us I would like to know how to get this taken care of so I can cut them off and get them off of my phone I need somebody's help as soon as possible thank you

When you open firefox private mode, it says leave no trace. Assuring users that whatever happens in their private session, stays in that session, but this is a blatant lie and firefox knows this. Go to any site that has cookies, or user login, or something similar. login into the site. Than simply remove firefox from ram. Now open firefox again, go to private mode, and go to that site. Most of the time, it still remembers the user. This issue has been present for far too long, not addressed, still pushed to the users that it is safe to use. Instead of warning the users, it is promoting them to use it by saying leaves no trace in this new update. This is unacceptable.
