Thunderbird Issues and CCleaner

I am having all sorts of issues with TB and they are cautioning me (if I am a CCleaner user) to be sure that TB files and folders are not erased.

How do I go about making those exclusions?

Thanks, Larry

when TB is installed, you should see it's entry in the Application tab of CC.

uncheck all entries in there.

then as an extra precaution, for the first time you run CC with TB installed, do a Analyse (rather than a Run Cleaner) and check the results for anything TB related.

(fyi: you can double click each categories shown in the Analyse results and get a expanded, detailed file list)

Perfect. Thanks!!! Turns out my issue was the Lightning Add On.

no worries.:)
