NOT OBSOLETE! Rated 5 out of 5 stars

Thank god it still works on FX20. Just realized how bad I need something that tells me how big a file is before I start download. Found this with notice that it is no longer being developed. First time I've ever seen the "+ (obsolete)" notification for an add-on ever. Not. Works fine. I tested it on some links at archive.org
https://ia600401.us.archive.org/16/items/newenglishdictio102murruoft/
and it's fine. Sometimes I have to click on the 'get file size button' but then it shows me what I need to know!!! Hooray for the developer wherever he is...

No, this addon is not obsolete, because Element Properties won't show any anything interesting anymore, e.g. file size.

I use this add-on I don't know how many times a day, especially with downloads. Worth being updated, at least in version compatibility announced.

Can we have an option to show in Kb / Mb instead of KiB and MiB? I'm used to the American style prefixes and such,
