ignore the user agent, i had a 4.0 agent set for checking another site, the bug was reproduced in a clean profile however, so its unrelated.

[Matthias Versen [:Matti]]

Can you please try to find the regression range ?
Either by downloading nightly builds or with a tool like mozregression.

Comment 3

[Danial Horton]

i'll check a few builds from around the 20th of feb, around that time is when this started happening apparently.

Comment 4

[Danial Horton]

first occuring in 20120218

Comment 5

[Matthias Versen [:Matti]]

Thanks !
Can you post the build rev from the first bad and the last good one ?
The rev is the URL after "build from" in about:buildconfig

im kinda finding it hard to see why that buildset would break it,  did any merges happen between the 17th and 18th of february?

[Matthias Versen [:Matti]]

I also fail to see something that would explain this in http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=2271cb92cc05&tochange=550779e6bab4

Have you already tried the safemode and a new profile ?
Do you see errors in the error console ?

comment 1 Matti.

the new simple bug reporter template makes it easy to leave out important info in the initial post.

Comment 10

[Danial Horton]

i would've been quick to blame Bug 713936, but SSL was indeed disabled with my tests.

the 2 builds i tested were launched from profile manager into a temporary profile.

the 2 PGO green merges from inbound however, do scream potential cause to me.  PGO can break things in wonderful ways......

Comment 11

[Danial Horton]

i left it out of my initial post before because i usually didn't notice it with the test files i was using, but when you first drop a file onto the mediafire site it validates or verifies the file first 

This performs some kind of hash check to see if the file already exists on Mediafire and if it does it is instead copied into your account instead of uploaded.

It never performs this step, hanging at the queued phase after the affected buildset.

I submitted a request for mediafire devs to get in touch here as well.

[Danial Horton]

"Hello Danial,

Thank you for bringing this to our attention. I have forwarded all relevant information to our development department so they can review this bug. As soon as we have something to report we'll let you know."

Comment 20

[Loic]

Good! To be clear:
Instant Upload (My Account > Upload Options > HTML5 Uploader is Enabled > Instant Uploads: ON) doesn't work with Firefox 13 because Mediafire is using Blob.mozSlice that has been unprefixed recently in Firefox 13.
Result: uploads stay queued and local hashing runs in infinite loop.

@all, update to MediaFire.com code yesterday is believed to fix this.
