Rated 2 out of 5 stars

I hoped to use this add-on to import profiles from Windows 7 T-bird 68.0 to LinuxMint 19.3 T-bird 68.4.1. Compatibility to T-bird 69.* is claimed. There is NO Import selection I can find in the Linux version. Neither could I find a bug report link so I'm making the problem known here.

This review is for a previous version of the add-on (4.0.4).

Sorry for the confusion. Could you move this over to the repository where we can interact? That will help us solve your issue together:

Also just briefly, I have both users and myself using Mint with success . For importing profiles, the option under the main Tools menu at the bottom of the menu has the IET Menu. Just above options at the bottom are the import and export profile options. I was just running And looking at that on Mint
