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 Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1334316 Title: Input field text is cleared when clicking "edit" of a webpage Status in “firefox” package in Ubuntu: New Bug description: After some day I updated my ubuntu 14.04, sth wired happened to my web browsers. It's really difficult to describe, so just try the following steps to see the problem. Steps: 1. Open the html file in the attachment. > (This html source was saved from this link: https://bugs.freedesktop.org/show_bug.cgi?id=mab4.2 . You can reproduce this bug behaviour by login to this page directly, but I am attaching it to this bug report in case you do not have libreoffice bugzilla account.) 2. In the line "Bug 65675 - (mab4.2) LibreOffice 4.2 most annoying bugs (edit) ", click "edit". > When click "edit", an empty input box shows up. However, the expected behaviour is that it shows an input box with the text "LibreOffice 4.2 most annoying bugs" in it. 3. Refresh the page; in the field "Depends on", click the "edit" link at the end of the bug numbers. > When click "edit", it shows an empty input box. However, the expected behaviour is that it shows an input box with the text "34467, 34957, 36799, 37223, ......" in it. > (This is where I realize this bug for the first time, when I input one new bug number in the empty input box and click "save changes", then "Depends on" field is cleared out with only one bug number retained) This bug behaviour did not happen before June. And I remember one day after June I updated ubuntu, then this bug behaviour appears. I was thinking this may be a Firefox bug, so I tested by installing Chroinum, but the bug is still there; also, this bug behaviour does not happen with Firefox in my Windows XP computer. I do not know which compenent this bug belongs to, so I report it under Firefox. This is really annoying, and is likely a regression. I hope will get fixed soon. Thanks!
