since upgrade to v29, pinned tabs don't appear and sometimes all tabs don't appear and open menu button does not work
My pinned tabs don't appear at any start and at some starts, I don't see the bookmarks toolbar (I can restore that by removing it from view-toolbars and then reselecting it). when this happens, FF also does not show any tabs and the Menu button does not work.
I have tried various suggestions found on here like deleting the sessionstore.js and re-installing FF, also tried disabling hardware acceleration in safe mode and still have the same problems.
Am reluctant to reset FF in case I lose my favourites and Bookmarks, is there anything else I can try?
I risked a reset which managed to delete my saved homepages as well as the settings and addons etc. However, it does seem a lot more stable now and most times I do get all the tabs where they should be, it's not 100%, will see if the next update helps further.
