After auto update to 102.2.2 NONE of my folders appear! Accounts are intact - but no email or local folders appear. I tried this (did not work) : ''''Menu icon > Help > More Troubleshooting Information Under 'Application Basics' - Profile Folder - click on 'Open Folder' A new window opens showing contents of your 'profile name' folder Exit Thunderbird now - this is important Scroll down - delete all of the following files. folderCache.json folderTree.json session.json xulstore.json Start Thunderbird check you have this : 'View > Folders > select 'All''''' I see a folder \AppData\Roaming\Thunderbird\Profiles\w1mt54e1.default-release that looks like it has all my stuff in it. When I do: "Under 'Application Basics' - Profile Folder - click on 'Open Folder'" that is the folder that opens. I hope someone can help I have no access to all my email. I'm kind of freeking out.
