CloseReview for Firesizer by ehdsj
Rated 1 out of 5 stars
Thank you for maintaining this add-on for so long. Unfortunately when I was auto-upgraded to Firefox 55.0.1 (32-bit) it now reports, "this add-on is not compatible with your version of Firefox." :(
When the addon is compatible again I will raise my review to five stars.
