Please note that if even a single instance of Firefox is ALREADY running, the problem described above will never occur. If I refresh the page (the purple starting page of Private browsing), its search box will immediately start working properly, displaying the Google logo and becoming clickable (in order to place the mouse cursor inside and start writing the needed search term). This problem is related only to that search box: no problem searching (Googling) the web using Firefox's Address bar or any other search method available in Firefox itself. My Firefox default search engine is Google. ISSUE: The search box in the middle of the purple "Private browsing" starting page will not be clickable and no (default) search engine loaded in it (no Google icon in it: it will be blank). Infact, the following problem will NOT occur if I click on the private browsing icon located "inside" Firefox, I mean the one in the sandwich menu at the top-right of an already-opened window of Firefox.

Click on a Private browsing "external" icon of Firefox (eg: the icon located in the Firefox jumplist in the Windows Seven task bar) in order to DIRECTLY open a single "private browsing" window. The following problem will occur about 7-8 times out of 10:
