The other day my son told me firefox crashed now when I open it all my bookmarks are missing and all of my addons are disabled. Not sure if he did something or if FF updated causing the issue. Looks like current version using is 9.0.1 Yahoo edition which i don't think is version I've been using. Can I see if this is a recent update & if I can go back to previous version which contains all my bookmarks and addons I had set up? Don't know what to do.

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.


It is possible that there is a problem with the file(s) that store the extensions registry.

Delete the files extensions.* (e.g. extensions.sqlite, extensions.ini, extensions.cache) and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

See "Corrupt extension files":

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the Tools button at the left side of the Search Bar (or click the "Find Updates" button in older Firefox versions) to do a compatibility check or see if there is a compatibility update available.
