Files larger than about 2Mb are failing to upload

Whenever I try to upload a file larger than about 2Mb, the upload freezes and times out. I've tried refreshing Firefox, removing addons, running in safe mode, clearing the cache and deleting and reinstalling Firefox but the issue still arises. The only thing I think it could be is that there is an Adobe Acrobat - Create PDF 1.1 addon that is disabled but I don't know how to remove the addon. But this may not be the issue. I've only noticed this problem in the last couple of months. Thanks, Ben

The service that the file is being uploaded to, is there a file size limit?

No, the file I'm trying to upload is well below the file size limit. For example I've just tried to attach a medium sized image to this post and the upload failed. Works fine in Chrome. Thanks.

Do you have any security (Anti-Virus) software that might be blocking this upload in Firefox?

I cannot upload files to Dropbox using Firefox v43.0.2. if they are larger than 1MB

I reloaded Firefox v40.0 and the uploads worked fine for any file size,

The text below was on the web console 'Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://dl-web.dropbox.com/chunked_upload?name=img001.jpg&chunk=0&chunks=1&dest=&t=_pl3E97rfmxejGwnYhEiJ8-5&_subject_uid=188228924&reported_total_size=1129807&upload_id=s5Qn7TJYL3B5Dttt1eMamQ&offset=0. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

I don't usually take the beta versions but I tried FF44.0B2 and it has fixed the problem and dropbox files are being uploaded OK

Hello, I tried to investigate if there was any changes in the singe origin/cors/cross domain stuff for that next version: https://bugzilla.mozilla.org/show_bug.cgi?id=1214819 was listed in the release notes for developers. It seems that is not the only site affected.
