As for firefox 15 beta 6, firefox just silently fails. Eg: trying to upload the unreadable file (eg: echo >test.txt;chmod 000 test.txt) result in nothing happening when cliking on submit (tested on bugzilla, webmail, ...)
I've reported a similar same issue in chromium and it was fixed : https://code.google.com/p/chromium/issues/detail?id=30850&can=1&q=vignaud&colspec=ID%20Pri%20Mstone%20ReleaseBlock%20OS%20Area%20Feature%20Status%20Owner%20Summary -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/152038 Title: unreadable file form upload submits as empty file To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/152038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
