BackMark - Back up the pages you bookmark
Automatically back up the web pages you bookmark. Link rot is real. Stave off some of the damage with easy and automatic backups. Whenever you add a bookmark, Backmark will save a copy for you. You can then download it from an easy-to-use menu as a zipped MHTML file. Note: Downloads of multiple backed-up bookmarks at once is flaky and the resulting zip files may be corrupt. Work around this by downloading each individually.
