Browser won't stay logged into any sites

Hello John,
We would like to understand more about the situation. Let us know how long you are facing this issue. Did you perform any recent update with AVG products? Have you installed AVG AntiTrack? If not, let us know the name of AVG product you have installed.

Every time I go back to an email or any other site I have to log in again. I use firefox and it's not the cookie setting there as the box is unchecked. Is this a setting with AVG?

Hi John, 
The issue is more likely related to browser itself. Could you please try accessing the web pages in alternate browsers and verify the status?
If this continues to be the same, please uninstall AVG AntiVirus free version as mentioned here (https://support.avg.com/SupportArticleView?urlname=Uninstall-AVG-AntiVirus-Free) and check if that fixes the issue. 
Thank you.

I have the free version of AVG. I've had the problem a few weeks and I think it started after an avg update.
