You're not using Private Browsing, are you?

Very seldom, but I did use it about ten days ago. Tnx for the quick reply! Alexander

Do you have any programs installed on your computer that automatically deletes browser cache and history?

Do you have an automatic history and cache cleaner extension installed in Firefox?

Try disabling the Do Not Track Me extension to see if your history is then saved.

No programs to automatically delete caches... never heard that such a thing exists, as a matter of fact.

Just changed it to "Tell sites that I want to be tracked" ... even though this ain't really want I want. <GGG>
