User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0 (Beta/Release) Build ID: 2014060900 Steps to reproduce: Log in to Intelligent Finance (UK online banking brand) at my.if.com. Clicked clickable part of page once logged in Actual results: Took me to page saying I'd been logged out because of security around timeout i.e. I'd spent too long logged in without being active. Expected results: Taken me to whatever aspect of the account I had clicked to view. NB logging in and clicking logout immediately returned the same timeout error page (instead of the expected "thanks for logging out" page) i.e. it's anything on the page, not just banking aspects. Tested with new private window to (I think?) eliminate cookie issues etc.. Logged in with Chromium without issue. Used FF29 on same machine and same connection at weekend without issue. Site is not complex with tech > 6 years old in its fundamentals (more or less abandoned brand since Lloyds acquisition during banking crisis).
Please try Safe Mode (maybe an add-on has changed?): https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode
Ok, cannot reproduce, will assume just some one-off related to the upgrade or a change at their end. Marked resolved WFM.
