Another thread that could not save bookmarks had to replace the places.sqlite file, however do not do this until you export a back up of your bookmarks. I might try this first: *See if it works in Safe Mode: [[Troubleshoot Firefox issues using Safe Mode]] *Then try: [https://addons.mozilla.org/en-us/firefox/addon/places-maintenance/ Places Maintenance] * New profile: [[Use the Profile Manager to create and remove Firefox profiles]]

You can check for problems with the <b>places.sqlite</b> database file in the Firefox profile folder. *http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox *https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file *Places Maintenance: https://addons.mozilla.org/firefox/addon/places-maintenance/ ---- You can try these steps in case of issues with web pages: You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files. *Hold down the Shift key and left-click the Reload button *Press "Command + Shift + R" (Mac) *Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux) Clear the cache and remove cookies only from websites that cause problems.
