User Agent: Mozilla/5.0 (Windows NT 5.1; rv:33.0) Gecko/20100101 Firefox/33.0 (Beta/Release) Build ID: 20140705030203 Steps to reproduce: Go to a page with a table (e.g. http://ftp.mozilla.org/pub/). Now press Ctrl key, and keep it pressed during each case. Case 1: 1. Doubleclick a cell A Selected cells: A Selected text: A 2. Click some other cells B1, ..., Bk (different than A) Selected cells: A, B1, ..., Bk Selected text: A 3. Click cell A again Selected cells: A, B1, ..., Bk Selected text: none 4. Click any cell C (can be A or Bi) Selected cells: C Selected text: none Case 2: 1. Click a cell A Selected cells: A Selected text: none 2. Doubleclick another cell B (different than A) Selected cells: A, B Selected text: B 3. Click cell B Selected cells: A, B Selected text: none 4. Click cell B again Selected cells: A, B Selected text: none Actual results: In case 1, clicking a cell selects it (even if it's already selected) and unselects all other cells. In case 2, you can't unselect cell B by clicking it. Expected results: That shouldn't happen. And maybe double clicking a cell shouldn't select its text.

Dup. of bug 1035036?
(In reply to Takanori MATSUURA from comment #2) > Dup. of bug 1035036? Bug 1035036 is about clicking links in tables, and doesn't seem to cover double click. This bug doesn't need links, it can be reproduced with text cells too.
