Not reading messages at start up and losing all ope mail tags on shut down
Hi I'm a long time user of Firefox and have had virtually no problems over around 20 years. I particularly like the flexibility for backup and email file storage.
I store my email files on an encrypted partition. I have been doing this for around 6 years and I have had no problems - until a couple of days ago.
My two problems are 1) Even though the "check for messages at startup" box is ticked it doesn't do this and 2)Any emails that are open at the time of shut down and no longer open on restarting
Both problems arrived at the same time. I increased the size of the encrypted partition mainly because there was no longer sufficient free space to allow the folders to be compacted. Around this time there was also an update.
I have tried uninstalling Thunderbird and reloading but alas no change
The partition identification letter is unchanged
The profile is still on the C drive. When I deleted it before uninstalling Thunderbird, Thunderbird wouldn't start ( I had expected it to create a new profile ). On replacing the profile from a backup, Thunderbird started up just fine but the problems still existed.
This is not a show stopping issue but with 6 email addresses to check and frequently leaving emails open under a tab as a reminder until the issue is dealt with, it is an inconvenience.
If anybody can suggest how I can resolve this irritation I would be very grateful.
The file is called 'session.json' and it is in the 'profile name' folder. Example image below - ignore the 'mailviews' that is underlined.Funda le mpendulo ngokuhambisana nalesi sihloko 👍 1

Slight correction to the first line
Although I have used Firefox from the very early days, I should have written Thunderbird.
It sounds like the session file is not retaining session data, so I'm thinking it is being 'cleaned up' by another program. Do you have any product that cleans up files eg: CCleaner or an Anti-Virus with same abilities? If yes and you like to use that product then suggest you make exceptions for the Thunderbird profile folder and files therein, so nothing gets scanned and/or deleted.
Thanks for your thoughts.
That the session data was going astray seems a likely first step. Why is a bit of a problem.
I have been using Ccleaner regularly for at least 15 years. I've not had a problem before like this and so I judged Ccleaner was not the problem particularly as I consistently refuse the Ccleaner updates. If its working fine don't tinker unless there is a real security issue.
I have solved the problem. After a disc clone backup for security, I deleted the entire mozilla thunderbird folder in USERS/ROAMING and uninstalled Thunderbird. I then cleaned up the registry with Wise registry cleaner
On reinstalling and reentering all the email addresses and storage locations everything seems to be working fine. Still a mystery as to why the problem occurred in the first place after years of problem free use.
'CCleaner' and other similar products such as 'WiseCleaner' are well known for causing all kinds of silly inconvenient issues. The kind of files they can delete that seem to cause most problems are session, cookies and password files. It is recommended that you do not allow those types of products any access to any Thunderbird folder or profile file.
I've been helping on this forum seeing all kinds of issues for well over a decade. Whenever, I come across people who had session, cookie and sometimes password issues that could not be resolved by conventional methods, I am always dicovering that everytime those people are using a cleanup file product. Hence the heads up not allowing them anywhere near Thunderbird profile files. They are not required as there is nothing that needs cleaning up.
Over the years products may get updated and modified to include additional functionalities. Every update of an Anti-Virus can potentially cause issues especially if you allow it to scan Thunderbird profile folders and files. Even if you do allow it to scan, you should make sure there is no auto fix, it should ask so you can prevent it from 'fixing' as the likelihood is it will mess up something and more than likely delete emails you do not want to lose.
Sometimes, if session file has got corrupted, it can be fixed by exiting Thunderbird, access profile, delete the session file and then restart Thunderbird.
Thanks once again for your time and thoughts.
I am well aware of the issues around updates of auxiliary programs (not to mention Microsoft updates). I have old versions of both Ccleaner and Wise registry clean up that I have been using for several years. I have the original exe files archived and backed up.
These have not caused me any problems in the last approx 6 years.
I use Bitdefender for internet security and as far as I know it doesn't delete any files without permission. I've been using it also for around 6 years.
I have now reinstalled Thunderbird from scratch and all seems fine. I've kept all my old emails which was a key objective. However for future reference it would be very helpful to know which files are what you describe as "session files"
The file is called 'session.json' and it is in the 'profile name' folder. Example image below - ignore the 'mailviews' that is underlined.
