I wonder is it a bug or a 'feature' that standard
ctrl+shift+tab shortcuts to move between tabs in backwards are disabled.
about:config I have set:
browser.ctrlTab.previews;true, but it doesn't work, of course it is showing the previews but I can move only forward. Also extensions like: https://addons.mozilla.org/en-us/firefox/addon/ctrl-tab/ , https://addons.mozilla.org/en-US/firefox/addon/super-tab-mode/ etc. also do not work.
Ctrl+shift+tab seems to switch between fields in a form on a web page or between links or some other elements. This shortcut is working fine in opera and chrome. Only FF has problem here.
Are there any other keyboard shortcuts introduced instead of ctr+shift+tab or I'm forced here to use the mouse ?
