User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:32.0) Gecko/20100101 Firefox/32.0 Waterfox/32.0 Build ID: 20140903161535 Steps to reproduce: Highlighted text to be Hyperlinked, Copied URL for Hyperlink to clipboard, then selected link box from Thunderbird options. Next click once on box provided in Thunderbird, right clicked to paste and NOTHING! Tried Ctrl-C still nothing. See attachments. Actual results: Highlighted text should have been created. Was able to create/past intended URL anywhere on open text screen using Right Click, paste or Crtl-C but NOT in box for hyperlink creation in Thunderbird. Expected results: Hyperlink should have been created. Reported same problem when v31 was released a few weeks ago and at that time Ctrl-C was a workaround. Two "upgrades" since it's only gotten worst.
