An obvious workaround would be to export the bookmarks to HTML and open that file whenever you need your bookmarks.

hi. do one thing at a time.

without using xmarks, play bookmark some sites, restart FF, and see if the bookmarks stays.

you might want to start with a fresh ff profile for this.

Thank you both, yecril71pl and ieNine. Before I left this afternoon I tried to first 'Backup' my bookmarks (json file) twice from the library 'Import and Backup' menu item. I got the two following script errors:

Script: file:///C:/Program%20Files%20(x86)/Mozilla%20Firefox/modules/utils.js:798

Script: file:///C:/Program%20Files%20(x86)/Mozilla%20Firefox/components/nsPlacesDBFlush.js:248

Then I tried to 'Restore' the json file and got these script errors that halted the script:

Script: file:///C:/Users/me/AppData/Roaming/Mozilla/Firefox/Profiles/n8131uvz.default/extensions/testpilot@labs.mozilla.com/modules/experiment_data_store.js:101

This one twice... Script: file:///C:/Users/me/AppData/Roaming/Mozilla/Firefox/Profiles/n8131uvz.default/extensions/testpilot@labs.mozilla.com/modules/experiment_data_store.js:153

Script: file:///C:/Users/me/AppData/Roaming/Mozilla/Firefox/Profiles/n8131uvz.default/extensions/testpilot@labs.mozilla.com/modules/experiment_data_store.js:111

So could this be a problem with testpilot interference?

Finally, I exported the bookmarks via HTML and later imported the HTML file. I turned off my computer and left for the day.

I just returned home an hour ago or so and at least my Win7 computer loaded up FF and the first time in days, my bookmarks were all there. I won't get to the Vista box until tomorrow.

So, yeah, with Xmarks and HTML exporting I now have a good work around. But the script errors seem to me to be the problem with FF.

I'm gonna keep track for a few days and if this happens again, I will write up a support ticket and have better descriptions of what went wrong when and where.

Thanks again... ddearborn
