  • Firefox tried to Perform DCL. Firefox Not Open

doublefree

doublefree AFAIK this lists only apps running a ForegroundService I.e. it does not list apps running in the background.

yet it does show me apps which are running the background - it states "active" - what you might mean is that it doesn't show all processes?

angela Neither App is running and this messages are showing after every restart.

angela This error happens immediately after a restart every time.

Do you have some sort of auto-update?

angela package: org.mozilla.firefox:2016007175

And did you try to update the apk? since this seems to be an older build (whch would make sense for TOR tho)

angela doublefree So there could be other Apps running and I don't know? That seems bad. Why is Firefox constantly running in the background? And Tor? What purpose could that serve?

More user-friendly; apps start faster etc. That's why most Android-OS also use the "deep sleep" option for apps which aren't used regular. The lack of process control is indeed a problem with Android, imo

angela Is there a way to shut down or kill apps in GOS?

You can go into "apps", select an app and "force stop"

                  angela how do you check which apps or processes are running?

                  Settings > System > Developer options > Running services

                  You can also tap three dots and show cached processes

                  It is the sole reason why I keep my Developer options unlocked

                      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 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

                            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.

                                      thanks

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

                                        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 tap three dots in that list and view cached...

                                            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.

                                              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.

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

                                                    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.

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

                                                            doublefree I guess you have to uninstall all apps with RECEIVE_BOOT_COMPLETED permission (install-time permission)

                                                            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.

                                                              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)
