Review for Extra Folder Columns by t3st3s
Rated 5 out of 5 stars
Nice addons,
I partially agree with this comment:
>This addon looks cool, and it partly true, but very hard to use because of mixed unit
>of folder size. It's disgusting to see MB and KB in the same column.
I would prefer to know the KB data as well as the MB. The mixed unit folder size issue could be lessened if the addon allowed for customization: the ability to check and
uncheck which columns will be displayed.
To create your own collections, you must have a Mozilla Add-ons account.
