Look on your desktop. Do you see a folder called; Old Firefox?

Type about:profiles<enter> in the address bar. How many profiles are listed?

Hi,

No folder. there are only 2 profiles

C:\Users\Peter\AppData\Roaming\Mozilla\Firefox\Profiles\ljtlr6qz.default

C:\Users\Peter\AppData\Local\Mozilla\Firefox\Profiles\ljtlr6qz.default

Regards Drachsi

Switch to the other profile. Does it have the missing data?

Sorry, how do I switch?

Type about:profiles<enter> in the address bar. You can do it from here.

In the Firefox folder under Profiles I see a profile for yesterday called eo6s261p.default but it does not show in "About:Profiles"

Really appreciate your help and support. Regards Drachsi

That is odd. Try it this way;

Sorry forgot to enclose this image.

On the about:profiles page, look under the first profile and press the Launch Profile In New Browser button. Is the missing data there?

That is a profile folder. Whether it's your missing data . . . . .

Look for the places.sqlite file in that folder. What size is it and the date?
