So far, it looks I have the same problem.

Does anyone know how to solve this problem?

I'm also using FF3.

After reading this thread, I tried a zooomr's uploader but as some described above I couldn't bulk-upload.
I don't know why but I recommend other application to bulk-upload.

1) jUploadr
http://sourceforge.net/project/showfiles.php?group_id=127771
There are several versions. Use 1.2alpha1 version for zooomr.
* I'm using jUploadr to upload pics and it works well. Sometimes re-auth will be requred.

2) PictureSync
http://picturesync.net/
* I have not used this before but I'm sure some users upload pics with PictureSync.

Thanks Yanz.

i uploaded a small packet (3 images) via Zooomr's flash uploader last night. it worked fine (using FF2).

in the past i've experienced the one-upload issue. all i had to do was refresh the page and it went away.

The same thing happens with me, using IceCat (a Firefox clone) with Gnash under GNU/Linux's distro gNewSense 2.0. So, I've tried jUploader, but it doesn't work with IcedTea's free Java implementation.

jUploadr doesn't work for me either.

wow, this is really strange. I thought I was the only one having this problem. And it has been a problem. A PERSISTENT one.

why hasn't zooomr fixed this huge bug? if you can't bulk upload your pics... er.. WTF?

I guess this is the nudge I needed to move to a real photo site.
