My question disappeared so I'm trying again. Why is it not possible to import bookmarks and browser data any more. I had a sequence of horrible experiences with trying to get Firefox to do its basic functions tonight, starting with the disappearance of my newtab page. This then led me to try to update the browser to the newest version. First, I backed up my data. Including backing up the bookmarks two times to .html and .json files, both of which are saved. Of course, the new installation of Firefox is unable to read the old profile. Of course, because if it were able to do that the user would not have to suffer. Once a version of Firefox was finally installed, I tried to import my bookmarks. I have tried to perform this simple task 12 times; every time I try to do it, Firefox hangs and "is not responding." Then the only option is to shut down Firefox because it is incapable of doing anything at all.

Yes, I have latest updates to Windows 10. yes I 'm a chronic user of Windows and Firefox and yes, they never work right. Can anyone PLEASE, PLEASE describe in relatively simple terms how to get a version of Firefox that works the way it did before the August 10 security update (I presume that is the culprit) destroyed the newtab page, and then the new point upgrade of Firefox completely fails to allow the importation of Bookmarks, to say nothing of passwords and everything else that is saved in my profile from before. Please help!!, there is a lot of work pressure on us out here, and using Windows 10 and Firefox which are continually sabotaged by the software developers, causes immense stress. Thank you so much in advance.
