[error] Invalid tab ID : 5

[admin]

Thanks again for the info. This issue sounds similar to [Recreator Required] No tab with id: 1662 - #5 by admin - which is already on our todo list. I will update this post once we know more.

I solved this problem with my previous solution (testing a ok.csv I create at the beginning of the macro to test if the macro starts and if not kill Firefox for a fresh start of the command line).

This is a good workaround!
