Win 7 Ultimate 32 bit Sandboxie 5.24 Addons: Roboform 8.4.8.8, One Tab 1.25 I have tried the following both in and out of the sandbox with the same results, so I do not think this is a sandboxie issue. This may have started with Firefox 59.0.2, but cannot be sure. Issue: When I open the history box, and try to export the .json file to a drive where I keep my data, sometimes I am told that I have to save the json or html file to some other drive/folder. For example I try to save the history to F:\Bookmarks backups. Sometimes the save seems to work, and other times I am told to save to the computer name folder. But no matter where I try to save either the .json file or the .html file, it never appears in the location where I tried to save it. I have used the program "Everything" to search for the file I saved, but it is just not there. I have tried disabling the two add-ons, but that does not solve the problem. Has something changed in the way Firefox handles bookmark backups? I have refreshed the browser, using troubleshooting, deleted the contents of the sandbox, done an sfc /scannow but nothing seems to fix this issue
