Hello everybody, as already described, my chronicle was suddenly gone (https://support.mozilla.org/en-US/questions/1231311). Now I'm the cause of the glue gone and have found that the company computer since the last update prevents. This is a pity, of course, and I have also reported that to IT, they have switched to my computer, etc. and tried to correct this. I quickly realized that they have no real idea about their job. Firefox has been reinstalled several times, other versions and and .. Current status, I have to live with the fact that my chronicle is not there after a reboot, or I have to work with FF 53. This is just installed, but does not accept my 4500 bookmarks created with FF 62. Now I have FF 62 Portable installed on a stick on my home computer, set up with FF sync, etc., then plugged it into the company computer and it happens the same as when I install the browser locally. There is no history saved after quitting or working with FF Sync. Everything is grayed out in the settings. My approach would be that I in the registry or wherever the values change so I get full access back to my FF settings. Can someone tell me what and where to change this? Or. Where this is stored? Or can someone give me other tips on how I could get on? Greetings and thanks for answering
