Mozzilla Thunderbird creating popstate-1.dat folders when KTS active

[MPBurr]

I have an issue which I am unable to solve.

When I have KTS active and start Thunderbird it generates multiple popstate-1(and 2, 3 4 etc).dat and msgFilterRules-1(2, 3,4 etc).dat folders. It will often download messages multiple times.

I also cannot send emails when KTS is active

When I turn off protection I do not get the problems.

Any advice on how to prevent this would be greatly appreciated.

Hello @MPBurr,

Additional to @richbuff🙇

1 In KTS, Network Settings, Mozilla Firefox & Thiunderbird, which certificate store is selected?

2  Exit Thunderbird.

3  Open KTS, Threats &  Exclusions, Manage Exclusions: try adding an exclusion for Thunderbird Profile folder, the path is:

C:\Users\YOURNAME\AppData\Local\Thunderbird\Profiles\i0soxgur.default\ < note, your  .default folder may have a unique name, not necessarily i0soxgur 

4  Shutdown PC using Full Shutdown, not Restart.

5  Start PC, login.

6  Start KTS, run a manual Database Update - allow it to complete.

7  Start Thunderbird, recheck  “Thunderbird  generates multiple .dat” folders issue?

8  Check Thunderbird email send issue?

Please let us know?

Thank you.

Hello @MPBurr,

Thank you for posting back.

1. If “adding an exclusion” doesn’t work, try changing the certificate store for Mozilla Firefox & Thunderbird, to do that, it’s necessary to export  Kaspersky Anti-Virus Personal Root Certificate, then import the certificate, the “help” link is missing some info, see post by   @TomFiii ​​​​​​, I’ve documented the complete export process. 

🛑 The last option would be to “deselect” Scan secure traffic in Mozilla applications, however, if that actually resolves either the .dat folder creation & or the “send” issue, or both, you must contact Kaspersky Lab please, bc, (imo) deselecting Mozilla SST is a “workaround”, not a fix🤔🛑

Please let us know if anything works and or if you escalate to the Lab?

Thank you🙏
