Hey! I think you should try reinstalling firefox on android. If it does not help, try to remove the firefox on the PC.

Hi, thanks for replying. I actually already did that. Installed a fresh Firefox Android a few days ago and bought myself a brand new PC. So basicaly is everything new.

Hi

If you go to https://accounts.firefox.com/signin and sign into your Firefox account and select Connected Services, do you see both devices listed?

Hi Seburo, yes, they are all there. Actually it's all syncing. It's just that on the smartphone I have to regularly flush application cache to get it working.

How much free space do you have on the phone (not including any SD card)?

Which other apps do you have open?

Hi,

I've got 30gb free space. About the RAM itself it's hard to know. But I guess 8gb of RAM is definitely enough for my very very application selective way of dealing. I mean I only install applications that I REALY need. So not much.

How many apps do you have open?

Right now in the multi task menu I had 5 apps. And I believe most of them are already killed by Android system.

If you close those apps and restart your device, does the situation improve?

Hi Seburo,

had a try a few days, but still it's appening. I have battery optimisation off. So it's although not such a problem.
