This happens anytime I use Sync. The first time, it works perfectly and then any subsequent logins with Mozilla and all images are gone. This is a great option. I had to refresh my PC and sync had all my settings, bookmarks, etc. But then I have to refresh Mozilla and leave sync off. Kind of counterproductive. I have attached a link of the error log as was advised.

MJ, thanks for you bug report! Can you help me understand what you mean by "all images are gone"? It's true that on new devices attached to Sync we don't show the "favicon" for the site next to your bookmark and history entries until you revisit the site (instead we show a globe). We'll hopefully be able to work on an improvement on that soon: https://bugzilla.mozilla.org/show_bug.cgi?id=428378 Does this describe your problem, or is it something else?

MJ, attaching a screenshot of your problem would also be helpful.

Copying over the reporter's response added in https://bugzilla.mozilla.org/show_bug.cgi?id=428378#c53: "All the graphics are gone. Pictures, icons, etc. If I log onto facebook, where there should be pictures, it shows blank text boxes. For my gmail, icons for mail, drive, etc. are gone. Text is on top of other text, I think because the graphic isn't there. Sometimes it shows the 'broken picture' icon, sometimes it's blank. Depending on the website. When I refresh Mozilla and leave sync off, I don't have any problem. Does this help?"

MJ, Based on that description, I'm concerned that you're using an Add-on that's blocking images, and when you log into Sync, it's enabling that Add-on on your computer. Can you try disabling your add-ons, restarting, and see if the problem persists (https://support.mozilla.org/en-US/kb/disable-or-remove-add-ons)?

That was one of the first things I did. Didn't help. I have refreshed Mozilla and have reset everything and am just leaving sync off, so unfortunately, I can't send a screen shot. To give you an idea of what I mean, when I opened Add-ons Manager, there were no graphics. All the boxes under 'featured icons' were blank squares. And when I synced my laptop (windows 10), it did the same thing. Which bites, because it was so great to be able to sync all my favorites from my desktop to my laptop.

Thanks, MJ. I'm sorry you're having this problem. It indeed sounds like something we should fix. I've never seen this before, and it's going to be hard to proceed without further information. If you can provide us with further details in the future, please let us know.
