I am attaching this another test html source. I think the problem may be related.
Steps: 1. Open the attached html file in the text-editor.zip 2. Select some text in the text field, then try to apply "bold" or "underline" by clicking the icons of the built-in editor. Current behaviour: When trying to apply "bold" or "underline", selected text is deleted. However, by clicking the "undo" icon, deleted text will come back, with "bold" or "underline" correctly applied. ** Attachment added: "text-editor.zip saved from libreofficechina.org/thread-7-1-1.html" https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1334316/+attachment/4139081/+files/text-editor.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334316 Title: Input field text is cleared when clicking "edit" of a webpage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1334316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
