Review for ThunderBrowse by Aku
Rated 3 out of 5 stars
It's sad to see this great add-on not being maintained. It was a very great piece of software. Doesn't work with newer Thunderbird. Warning: Be on the lookout. Be careful of anyone other than the developer claiming to have fixed it and offering alternative download. i downloaded from external sources and regretted it. Yes, it worked but also got adware as part of the package. Don't repeat my mistake.
