When I update the bookmarks file by an editor (/home/user/.bookmarks/MyBookmarks.xml ) and I load bookmarks with the browser, the changes are not shown.
Even not after reboot.

In the past it did work.

Is there any other hidden place where bookmarks are saved ?

UPDATE:
I found out that it did work after clearing the browser cache, so the browser even caches the bookmarks file.

Any other experience ?
