Last upgrade not stable keep loosing history not able to bookmark pages

Hi James, If this started after a recent Firefox update, could you first let us know which Firefox version and operating system you're using? For the history issue, does Firefox lose your history every time you close and reopen it, or does it disappear while Firefox is still running? For the bookmarking problem, what happens when you try to bookmark a page normally (for example, by clicking the star in the address bar)? If you can describe what happens, we can narrow down whether the two problems are related.
