Hello everyone.

I'm noticing an abnormal battery usage in my Samsung Galaxy S24 Ultra. Ive used other Chromium based browsers without issues. Sadly I'll have to stop using it.

I have noticed that for the past several months Firefox for Android begins draining my battery after being installed for around 2 weeks. I'm using a Google Pixel 7 (128GB) running Android 14 (AP1A.240405.002) in the UK.

At first, I thought this was being caused by an add-on, so I reinstalled without add-ons and slowly started enabling them day by day until I caught the culprit (which if I recall correctly was Dark Reader). However, even after I disabled the Dark Reader add-on the problem persisted, and no matter how many times I uninstalled and reinstalled the app, the background battery drain issues would eventually come back after ~2 weeks of being installed.

At present I have only three add-ons enabled in the browser: ClearURLs, Decentraleyes, and uBlock Origin. I have used these add-ons in the browser for years without any issues.

It's now got the point where I am so fed up with this issue and the need to constantly reinstall that I will be using a different browser for the time being until this is fixed. I really want to use Firefox as I use it on all my other devices, but this is too much of an issue for me to ignore.

I've included screenshots of my phone's battery consumption whilst I'm asleep, and whilst I'm watching Youtube on my TV over lunch. Both of these are times I'm not using Firefox.

Any help on this issue would be greatly appreciated.

Firefox 125.0 Beta 9. Why so much memory usage in background when Firefox is not open and in use? (See Screenshot). Never noticed this before on previous Beta versions. Otherwise this version works good and no crashes.

Dear team, 1) thanks for your work! 2) I can observe a quite important problem which could make me uninstall the app. Mozilla is now draining much power, even while not using it (e.g. at night where I can monitor the problem). I can observe that since I switched to a pixel 8 phone. (Which has itself a poor living battery). The phone can hardly survive a day and a night without being charged. And when charged on everything. It can loose up to 30% battery until the morning. Another phone could be 5%. What really strange is android show me that during that period of time Mozilla was responsible for 90% of this leakage. I had sync enabled.(Tabs, history and bookmarks) I removed it, but the leaked percentage of Mozilla at night stays around 70%.

Firefox android RAM memory usage gets sometimes high. I have no addons and only view tabs. Max RAM usage rises to 2 GB and my phone freezes. Opera always runs smoothly with no problems.

Firefox has been a great browser on my new S22 however I have noticed recently that it has been dropping my battery percentage extremely fast, and I notice its lower almost every minute I check. This is confirmed in the battery settings menu where it shows an abnormally high amount of usage, when I mainly use Firefox for general browsing and close background tabs.

I have a strong phone sd 870 and 6gb ram so need to put the blame on that.. but this browser keeps refreshing the webpage as soon as I leave to other apps.. yes I tried with no battery restrictions but didn't solve the problem
