Dear community, I have been using FireFox since the version 1.x - none of the problems I experienced in the past made me create an account on Mozilla.org. After the upgrade to 45 from 44 ( now 45.0.1 ) I need to delete places.sqlite to get the favorites and tabs open properly. Initially I tried to fix it via the plugin(s), and manually from the cmdline using various how-to's, and restoring the backups I make from time to time. I finally ended up staying on v44 for around 1-2 weeks. Since this is the only Windows system I am using as my desktop/workstation at work/home I blamed it again on "Windows". But finally the places.sqlite stopped "working" also on v44. So I keep on deleting it almost on every FF restart to get the favs back. I do not remember any new plugins being installed within a few weeks before noticing this problem. Is there any other file that would have to be removed/fixed/checked in order to stop the corruption of the sqlite db? or a setting? Thank you, Mike
