I am using feisty, as in the summary field. I just confirmed that it is due to the "Html Validator 0.8.3.4" extension. Everything works after I disabled it, and it breaks even if only this extension is enabled.
Error Console shows:- Error: oTidyUtil.tidy has no properties Source File: chrome://tidy/content/tidyBrowser.js Line: 188 -- [feisty] Back/Forward buttons cease to work https://launchpad.net/bugs/85587 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
