See if this helps,

Type about:preferences#privacy<enter> in the address bar. The button next to History, select Use Custom Settings.

Turn off Always Use Private Browsing Mode Turn on Remember My Browsing And Download History At the bottom of the page, turn on Clear History When Firefox Closes. At the far right, press the Settings button. Turn on ONLY Cache and Form And Search History leaving the others off.

Nothing changed.

When I go to Amazon it still does the same thing I sent you. Reverting to the same search and opening a box with all the titles which include the search. If I clear the search and do another search it will find that item, but them reverts back to the above search and opens the box with the included titles again.

Iexplore or Chrome does not do this!

I did a virus and adware scan and nothing was found.

Please help, or I will have to quit Firefox, as I use Amazon a lot.

Thanks; Chuck Hurst

I finally fixed it. I signed out of Amazon, closed Firefox and re-started. I then signed into Amazon again. No more problem. So there is a switch being turned on at Amazon thru Firefox that lingers. CH

That was very good work. Well Done. Please flag your last post as Solved Problem as this can help others with similar problems.
