Firefox tried to Perform DCL. Firefox Not Open

ILIKETRAINS

angela I dont know what it is or how to check it.

There is an app for that - or via developer options; this guide should work:

ILIKETRAINS i never ran fitefox or requested it to autostart and it is not showing in active app.

i think this is some exploit or ive been hacked. i should probably stoping using gos :-( cell phones are too frequently targeted

angela I don't see developer option

you might need to activate it. Go to "setting" > "about phone" and tap like 7 times on the "build number" 8at the end)
A message like "you're now a developer" should appear

angela i never ran fitefox or requested it to autostart and it is not showing in active app.

wait...? You have a browser that you don't use?
And the most stupid question: what a about de- and re-sinstall?

angela i think this is some exploit or ive been hacked. i should probably stoping using gos :-( cell phones are too frequently targeted

well... GOS shouldn't be blamed. But indeed, smart phones in general - as you said.

Any source for the "cell phones are too frequently targeted"?

angela activate it by tapping 7 times on Build number in Settings > About phone. Don't go playing with anything else, just view the running services

angela

ILIKETRAINS i can de and re instill but i wish i knew why this happend

is firefox starting up then shutting down at startup?

angela

thanks

i activated it and looked at the runnjng processes. firefox is not there.

I had the same issue. After stopping the app from the Seetings>Apps menu Firefox ceased to annoy me with failed background stuff. I haven't used it ever since.

I don't know why Firefox assumes it's ok to start background processes and I've never bothered to check. I know FF on android still shares usage data (or whatever) despite unchecking the box in the settings. So I assumed it had something to do with that.

I think it's a bit premature to assume you've been hacked because FF generates errors. It's certainly not trivial to hack into a GOS device and I doubt that a sophisticated attack would solely rely on Firefox. Before you start to reset your device try to rule out any other possible explanation for FFs behavior. Then, if being hacked is still the most likely explanation proceed with a clean reinstall of GrapheneOS.

I just tried on my phone with a fresh install of Firefox, and I get the same error message.

Firefox must be trying to start in the background for some reason. Maybe to get notifications, sync bookmarks, or whatever. I'd suggest you ask them in one of their communities what their app is doing in the background.

I doubt you'll see it in any lists of running apps because Firefox may just start up quickly, do something and close again within seconds.

After disabling Settings > Apps > All apps > Firefox > App battery usage > Allow background usage, I haven't seen the error pop up. It probably would stop popping up if battery saver mode is on, too. Firefox may request to run after the phone starts up, so it popping up after a restart wouldn't be surprising.

I'm deleting Firefox.

I knew it had telemetry but autorunning on boot without telling me is a violation of trust.

Is there a way to see if other Apps engage in this sort of Tretchery? Tor browser is giving me the same error.

[deleted]

angela it's not a treachery but added functionality :) you need to calm down a bit please and keep learning. I myself have a long way to go. But you are right to let go of Firefox, Mull and all things alike. Stick with Vanadium, our devs are very smart guys.

I guess you have to uninstall all apps with RECEIVE_BOOT_COMPLETED permission (installt-ime permission) which are likely >50% of your apps.

Does Vandium make users stand out through conventional fingerprinting (canvas, audio, textmetrics etc)? My threat model involves risks of being tracked and fewer risks of being hacked. I could disable the background usage of Tor.

It's really unfortunate that not only do Tor and Firefox both have this error, but it's done in a way that could allow for an exploit.

flighty_sloth

angela My phone does the same thing with both Firefox and Tor, so it's not unique behavior to your phone.

I am sure you already know this but you can check your browser's fingerprint here: https://coveryourtracks.eff.org/

It may or may not be very accurate but it provides a good first impression on your situation.

This one (https://browserleaks.com/) is a little more in depth. I am sure there are others.

Well... Orbot perhaps? But it might opens a new vector at entrance nodes for you. Depending what VPN-app you have to sacrifice
And your firefox and TOR browser share the same issue bc TOR browser is a modded firefox

The devs here themselves here acknowledge that their security with vandium is high but their anti fingerprinting isn't "there yet" (but also not the biggest fans of TOR(-browser) when speaking about their browser)

There are ways apps can tell if a device has booted even if they do not have this permission. Unfortunately many of the install-time permissions are misleadingly named or they suggest an app can not do something which is still possible. It is easy to get confused by looking at those permissions.

AcidDemon It was a subjective statement without any numbers, like "Pink is a pretty color." There have been many cell phone exploits that people didn't discover until later, many think MBS's assasins were possibly able to slaughter a journalist because of one such exploit. (Even if the exploit didn't lead to the meeting, the knowledge that he was encircled and monitored in ways he didn't know may have.) Even if there is bias from reading only the worst cases, there are many ways user privacy is targeted with cell phones to an extreme amount and and it shouldn't be a controversial statement.
