The FileLink feature probably won't get fixed for a long time by
Mozilla. When you go to add a filelink service in Thunderbird, you're
presented with the following choices:
Box (their local client corrupts Start menu)
UbuntuOne (dead, no longer free)
YouSendIt (died, became Hightail, no free services)
So the only working and free filelink service that you can select is
Box. I quit using them after a month of having to remove the "Box"
subfolder their local client kept re-adding to my Start menu everytime
it performed a covert update. I moved the shortcut (not folder) for Box
to an Online subfolder where are shortcuts to OneDrive, Google Drive,
Dropbox, and where I had Box. No complaints with their service but
their local client kept screwing up my Start folder.
UbuntuOne discontinued their free file storage service. YouSendIt
rebranded to HighTail almost a year ago, so I doubt any URLs in the
filelink service coded in Thunderbird will work anymore, plus Hightail
doesn't have any free service. Yet I suspect we will see these listed
as filelink services for years to come in Thunderbird.
There is an add-on to add Dropbox as a filelink provider in Thunderbird.
I'll probably trial that add-on since I have a Dropbox account; however,
users have complained about it not working or with poor behaviors.
Their help (
https://www.dropbox.com/help/5/en) says there is no max size
to the uploaded file (up to your disk quota) but I recall it was 500 MB.
There is an add-on to add hubiC (25GB free). There's an add-on for
FileSwap, too: 15GB disk quota but only 250MB max per file, plus they
throttle download speed to 250kbps for free accounts - DAMN SLOW for
large files which is what the filelink service is supposed to
facilitate. Dropbox downloads are slow, too. I've never measured
download speed for downloads from OneDrive (aka SkyDrive).
I'm currently using free aDrive: 50GB quota, 2GB max file size. They
also throttle their upload and download speeds. A 511MB test upload
went up at 130kbps but a smaller 37MB test upload went up at 200kpbs to
2Mbps. They all seem to do this and have you pay to get higher
bandwidths. Their desktop client is not available with free accounts.
Not only can I upload files but I can upload entire folders (rather than
upload a bunch of files). When sharing a file/folder, the recipient
doesn't need an aDrive account. The link takes them to the aDrive site
(yeah, they're going to advertize themself) but it points at a file the
recipient can download with no logon. The 37MB file downloaded so fast
that it was over immediately after I clicked the button. I had aborted
the 511MB test file because it would've taken an hour to upload, so I
didn't have that one to see how fast would be the download speed.
I wonder if I could add a filelink provider in Thunderbird *without*
installing their local client. Or are these filelink services in
Thunderbird using the local client to perform a background upload of the
file(s)? If so, it seem highly likely that the recipient of an e-mail
with a filelink will get the e-mail long before the file becomes
available on the server (uploads take time).
I've noticed some of the complaints about this FileLink service in
Thunderbird is that they stop working because the online storage
provider changed their login page. That leads me to believe that the
code in Thunderbird is either a screenscraper looking for input fields
or is using names of the objects, like the input textboxes with names of
"username" and "password", to walk through the web site. I remember
using YahooPOPs a long time ago (long before Yahoo Mail added POP, IMAP,
and SMTP access last November) to access my Yahoo e-mails. Any change
in the login page or the URL navigation between pages resulted in a
broken YahooPOPs proxy. You had to wait a couple weeks before the
author fixed his proxy so it matched on the changes at Yahoo Mail. So I
have to wonder how fragile are these filelink services in Thunderbird.
