Because Firefox is often very slow or hangs, I followed the instructions on support page "Firefox hangs or is not responding - How to fix". The instructions include : In the Firefox profile folder, find and rename the files places.sqlite to places.sqlite.old and places.sqlite-journal to places.sqlite-journal.old (if it exists). I followed the instructions and found the places.sqlite file, but not the places.sqlite-journal file. However, when I did a search of my HD, I discovered a folder called "mozembed" lurking inside the folder for the game "FallenEarth"; inside mozembed was another places.sqlite file as well as a places.sqlite-journal file. Any attempt to move the files out of their folder doesn't work; all you get is an alias. What is happening here, and what should I do? Dump the entire mozembed file?
