when i choose show your bookmarks i have the correct list and favicons as i had in previous versions of firefox ,im using the light theme and its applicable to all themes,so here is the issue..moving your mouse pointer over the selected bookmark use to give it a dark blue highlight and any bookmark you chose would highlight like this,now i have no highlight on placing the cursor over it,just a text box in mono showing the url this seems a bit vague when moving over several bookmarks and none is highlighted.ive recently moved to windows 10 pro and was clean install and up to date with a new profile on firefox .only the bookmarks were a html file imported from a usb stick so cant see that being an issue. firefox is also up to date with adblocker ultimate as the only addon.
