I've tried to follow the instructions given in https://support.mozilla.org/en-US/kb/import-bookmarks-google-chrome?esab=a&as=aaq Firefox says that it imported cookies, bookmarks and history. I can see the bookmarks. When I try writing a URL I've visited, it is not filled in the location bar. I've looked through the history, and I do not see any of the webpages I would only visit using Chrome - I've tried to keep a distinction between work browser and play browser, so these are quite typical. They are also important as history, if I am going to switch to FireFox being my work browser.
