Firefox tried to Perform DCL. Firefox Not Open

angela

I am getting notifications that Firefox tried to perform dcl. I have Firefox. it isnt opened or running in the background.

angela

angela I get these DCL error notifications from Tor Browser and Firefox even though I am not starting either App and neither App is running in the background

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

angela How do you know that it's not running in the background.

Browser have a JIT for JavaScript and Wasm, so they required DCL from memory.

ILIKETRAINS

doublefree you can slide down the not. menu and at the end there is a circle and a number next to the user symbol.... you will see all running apps.

JIT... Just in TIme... so the browser shouldn't run and execute codes at random and not in the background...

@angela
Do you have also an alternative browser?
TOR browser builds upon Firefox so the issue might "just" be firefox-code related?

Does it happen somewhat regular?
if so: Does it try it also when the network permission is disabled?
Did you re-boot?

angela

doublefree I did a full restart and keep getting this error. If Firefox and Tor are launching something at App start that's a concern or I could be hacked.

doublefree

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

I rebooted. Ive probaly rebooted 7 times since update.

It doesn't show on the list of running Apps.

Firefox shows as trying to use natibe code debugging and DCL

type: memory_DCL
osVersion: google/bluejay/bluejay:14/AP2A.240905.003.F1/2024090400:user/release-keys
package: org.mozilla.firefox:2016007175

DCL denial type: DENY_EXECMEM

Tor mentions DCL too but not native code debugging.

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

In the log these errors are showing up currently, within past hours, after restart with neither App opened. I care less about the error than the Apps doing stuff without being opened.

angela

ILIKETRAINS I have alternate browsers.

This error happens immediately after a restart every time.

It does happen with network permission disabled.

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?

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

Even with GOS, it seems I don't have control and don't know what this system is doing. The hardware is so modern and the OS is so smooth but stuff like this makes me want to change to something that I can control.

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)

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 did you check cached background processes also? It likely autostarts after reboot and suspends itself to launch quickly when you open the app, but even in that state it's still active. Until you actually open the app, it won't be showing in the list of running processes. That's just my understanding by observing behaviour of certain system apps.

angela

[deleted] Is this the same as active apps?

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

[deleted]

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

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:

[deleted] kudos for being faster around 1 sec

angela

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

[deleted] I don't see developer option

ILIKETRAINS

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.

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

[deleted]

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.

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