Rated 5 out of 5 stars
Can user see ReminderFox`s icon in Thunderbird`s toolbar without reminders (only icon)?This review is for a previous version of the add-on (220.127.116.11-signed). This user has other reviews of this add-on.
If you go to ReminderFox Options -> Firefox tab, under the Status/Addon Bar section, set the Limit Text to 0 Characters option to 0. Then you won't see any text. Hope that works for you.
