That is a feature of the default Firefox Homepage. Last week it was a simple video game.

Do this to get rid of that image and disable it from loading new images in the future.

1. Type about:config into the address bar and press Enter.
2. Accept the warning, by pressing the big button labeled "'I'll be careful, I promise!'".
3. In the search box, paste browser.aboutHomeSnippets.updateUrl
4. In the search results, double-click browser.aboutHomeSnippets.updateUrl to open the Enter String Value dialog box.
5. In the Enter String Value dialog, press the Delete key so that there's no text remaining, then press either Enter or the OK button. As a side-effect, only default tips will be displayed below the search box, because new ones won't be fetched from the web anymore.
6. Then type about:support into the Location Bar and press Enter.
7. Click the Show Folder button. A Windows Explorer window with your Profile folder opens. In that window, open the storage folder, then the persistent subfolder.
8. Then Exit Firefox with the Profile folder open.
9. Delete the moz-safe-about+home folder.
10. All fixed, you can open Firefox.

Thanks for the reply. I cannot get this to work. From step 5 onwards nothing seems to happen after I have pressed the delete key and pressed the Enter or OK button. I dont see where to type about:support, location bar? Regards Dave

Were you able to open the about:config page via the location bar and set the browser.aboutHomeSnippets.updateUrl pref to an empty string?

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
• https://support.mozilla.org/kb/Using+the+Troubleshooting+Information+page

Delete the storage\persistent\moz-safe-about+home folder in the Firefox profile folder with Firefox closed ("3-bar" Firefox menu button > Exit/Quit) to remove snippets stored in IndexedDB and make Firefox use a default snippet set.

You can reset the browser.aboutHomeSnippets.updateUrl pref via the right-click context menu to the default value to re-enable the snippets and make Firefox recreate the moz-safe-about+home folder.

Thanks the-edmeister and cor-el, the problem seems now to be solved. After rebooting my system and going through the procedures again it seems fine. Regards
