I want to Firefox to do automatic backup of the bookmarks file. It saves the file in the Firefox Profiles folder. To have it save the file in My Documents, I created the following new preference:;C:\Users\Gerry\Documents\BOOKMARKS. However, the bookmarks file was not saved at this location when I exited Firefox. I tried adding a filename to the preference: browser.bookmarks.file;C:\Users\Gerry\Documents\BOOKMARKS\Firefox bookmarks.html. It still didn’t save the bookmarks file at this location. How do I do it? How do I specify both the new file name and the path? The following is earlier correspondence.

Answer to question: How can I do automatic backup of Firefox bookmarks? What is the name of the bookmarks file and where is it probably located in Windows? You can make Firefox 3 create an automatic HTML backup (bookmarks.html) when you exit Firefox if you set the pref browser.bookmarks.autoExportHTML to true on the about:config page. That backup is created by default in the profile folder as bookmarks.html, but you can set the file name and path via the pref browser.bookmarks.file on the about:config page. Note: an HTML backup doesn't preserve tags and annotations, so you lose those if you need to import the HTML backup. See also:

Answer to question: I want to change the file location for the automatic backup file bookmarks.file, but I can’t find browser.bookmarks.file in the list on the about:config page. The browser.bookmarks.file preference does not exist by default. Right-click in about:config and select "New > String" to create it.
