User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0 Build ID: 2012042100 Steps to reproduce: On a dual-boot box: 1. Install TB on Windows 7, 2. mount NTFS drive from Linux, with proper permissions mapped between Windows and Linux users, 3. Install TB on Linux 4. Run "thinderbird -ProfileManager", create new profile, navigate to the profile on ntfs drive, for example: /win7/Users/MYSELF/AppData/Roaming/Thunderbird/####.default. Make the new profile the default one. 5. Configured TB to store local copies of messages. Actual results: The setup described above worked for me since TB versions 7 in Windows 7 and 3 in Linux. Indepenently on in which system I checked my email, I could open local copies on both systems. It worked with POP3 and IMAP accounts equally well, up to TB 11.0. Since I installed TB 12.0 (on both OS'es) I have connection problems on Linux (another bug report) an I can only download email from Windows. But the messages which I download in Windows are not visible with Linux version of Thunderbird. Expected results: I expect that if a message is stored in the profile, It should appear independent on the OS. This is a regression as it worked for a long time, even if versions of TB differed between OS'es.
Dear Hashem, The bugs you refer to are rather old. Problems described there could be due to filesystem problems, I do not recall since when NTFS is fully supported in Linux and TB profiles on FAT partitions probably differed due to fs constraints. As I stated, using NFTS-3G mounts to full extent (utf-8 long filenames, user permission mapping between OS-ses) I had no problems with this setup so far. However it might be also the case that the messages were in fact downloaded twice (in every OS separately) and I didn't notify. As I always store server-side copies, I did see all messages in both OS-es. How can I check, which way it really works?
YOu can log using https://wiki.mozilla.org/MailNews:Logging to see what's going on. Looking into Tools -> Error console is also a very good way to see things.
