<p class="MsoNormal">If we’re changing from 32-bit to 64-bit, Firefox won’t be in the same directory (C:\Program Files, instead of C:\Program Files (x86). The profile, however, sould be in the same directory. And I only used 80.0.1 because I couldn’t find

<p class="MsoNormal">We are currently packaging 78.2.0 ESR 64-bit for our internal electronic software distribution, and during my testing of the package, I notice that if I install over a 32-bit version
of Firefox (like 80.0.1) and I have saved bookmarks, after installing 64-bit, those bookmarks are gone. Is there a to preserve bookmarks when upgrading from 32-bit to 64-bit?<u></u><u></u></p>
