Hi, my firefox crashes everytime I rightclick on a bookmark/bookmark toolbar. Is there a solution to this?

The bookmarks + history data are stored in the '''places.sqlite''' file in the [http://kb.mozillazine.org/Profile_folder Firefox Profile Folder]. It may be corrupted. You can try deleting it after exiting Firefox. There is also a separate dated backup of the bookmarks in the '''bookmarks''' folder and you can restore the latest backup via '''Bookmarks''' ('''Alt''' + '''B''') > '''Show All Bookmarks''' > '''Import and Backup''' > '''Restore''' after restarting Firefox. Alternatively from here you can also '''Export Bookmarks to HTML''' before deleting the places.sqlite file and later '''Import Bookmarks from HTML'''.
