Sorry to hear about this problem. You could try doing it manually: export a file from Chrome and import it into Firefox. This probably will cause some duplication so you might want to test whether it works, but then clean out your bookmarks and do it for real. ''Chrome'' Scroll down to the "Move bookmarks to another browser" section of this article: https://support.google.com/chrome/answer/96816?hl=en ''Firefox'' Use the steps in this article: [[Import Bookmarks from an HTML file]] Now... that may lump all the bookmarks together into an Imported Bookmarks folder instead of restoring them to their original locations in Google Chrome, because many things do not match between the bookmark systems. You can use the Library window to re-organize. See the "How do I organize my bookmarks?" section of this article: [[Bookmarks in Firefox]].
