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?

Firefox may not have closed properly.
You can try to update to Firefox 29.0.1 to be released tomorrow (Friday) to see if that helps with this issue.

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.
