All, I know this is like a broken record, but I'm to a point where I'm about to give upon Firefox after all these years... After the last problem, reported here under two (2) entries - lost all favicons in the upgrades from 60 to 61, got to a point where I couldn't even delete any bookmarks, so I uninstalled Firefox completely, every trace, including bookmarks. I have had no desktop version of Firefox for sometime now, but did keep Portable Firefox updated, including bookmarks. I downloaded a fresh install of Firefox 62 this week, no issues setting it up, imported the HTML bookmark export file from Portable Firefox, no issues. Since the problems in 60 and 61, I now approach my bookmarks differently, I removed almost 3000 business bookmarks and now have them in a Word file, kept about 1000 active in FF. When I set up FF62 and imported from file, all my favicons were there in both sandboxed and unsandboxed Firefox (I use Sandboxie). Booted up this morning, all favicons are gone again, every single one of them. I have no issues with bookmark favicons in Portable Firefox, Slimjet (Chrome) or Waterfox - they all have identical counts and all favicons are present - just desktop Firefox and just since FF60. I have no issues with any of those browsers either sandboxed or unsandboxed either. I started with a completely fresh install, new profile, no bookmarks. When I downloaded and set up FF62, everything was great - I set up FF in an unsandboxed environment, always do. Portable Firefox, Portable Thunderbird and Thunderbird run flawlessly, I don't get it. What am I doing wrong? I am at a complete loss. Any ideas? Thanks, in advance.
