Again, Firefox is causing a huge battery drain on my Android device when it's not running. I've set everything up so that it has no chance of running in the background, yet last night I saw a 6% battery consumption, a large part of which was caused by Firefox. To avoid this, every time I exit I have to force close it.
I need a browser that works across all my devices, I would like it to be fully open source and have synchronization between my computer and smartphone. I would prefer it not to be based on Chromium. Firefox, if it didn’t have this issue, still consumes a lot of battery when in use and is slow on Android, but I could accept that. But for it to drain so much battery when not in use, no. Any suggestions for something I might have missed?
