Separate Security Issue, please update your Flash 20.0 r0, Flash 27.0 r0 by removing them with this : https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html Reinstall with Flash Player Version: 30.0.0.113 Current Version https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, . . . .) Note: Other software is offered in the download. <Windows Only>

I would guess that Sandboxie is doing what it is intended to do then. Or your Security software maybe blocking it. Would not know. You would have to review your logs to find out.

Current version is 61.0.1 this date : You can shutdown or try with Sandboxie running and see what happens and then go to Help --> About to update Firefox or you can do a install over top from a Full version installer :

• https://www.mozilla.org/firefox/all/

Please let us know if this solved your issue or if need further assistance.

Another user reported an issue with Firefox 60 in Sandboxie (could not post on this forum). Does Sandboxie have any advice on this?

Updated Flash. Update current version of Firefox

Running malwarebytes and defender, has not been a problem in past.

Same results. Firefox opens, but not homepage, not bookmarks will open, can type in a URL, but it won't open.

Cold booted system, same results, blank page.

Any other ideas?

None of the quantum versions 60.XXX worked sandboxed either.

Hi, know not why not working you think it would for sure. How about giving them a nudge and file a bug report. If you have a bug, file a bug report. https://bugzilla.mozilla.org/ Bug Writing Guidelines : https://developer.mozilla.org/en-US/docs/Mozilla/QA/Bug_writing_guidelines
