This is the 5th time I tried upload a huge ass file on TOR,
and the captcha expires before it can finish uploading.
Is there a fucking way it can verify the captcha first, 
then attempt or fail&report to upload the file?!?
This isn't blockBypass.js cookie, this is board-post captcha.js/captchaImage.

This shouldn't even be a bloody problem: You want to upload a file? 
First checkbox you want to upload a file, 
write your message, 
click take me to upload.js, 
and copy and past this key.

If should instantly fail if it detects a banned file type by just the header,
e.g. .exe, .elf, .out, etc., and reply back such, and link you back to your
thread. 
I prefer the open window/tab method.
