tabs disappear whenever I start Firefox 19

I normally Firefox put in place to have 5 tabs pinned and 2 or 3 tabs recorded since the previous session of Firefox. Since I have updated to version 19 FF, I lose 1 pinned tab whenever FF is started. I tried the fixes suggested on the issue of corruption of sessionstore.js file, checked to make sure that Firefox 'Will Remember history' is selected, the file used > Exit to leave FF. Whenever I start Firefox, it will miss a pinned tab (not all, just one). I started with 5 and I can go out, and then launch FF and only 4 pinned tabs are open. Repeat and only 3 are open, etc. If I have a normal tab open when I go out, it is saved & opens the next time FF starts, it seems open tabs is saved, but pinned tabs are closed. In addition, it is always the second pinned tab which is lost (counting from left to right). When there is only one tab left, pinned next time I restart FF, a normal tab is closed. Every time you start after that will close another normal tab until one pinned tab is on the left (the left most pinned tab). I have not tried to restart FF with only the one pinned tab, but essentially is that I lose 1 tablet recorded each time I have quit and restart and seq. anyone else see this behavior or have any suggestions to fix?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

  • Do NOT click on the reset button on the start safe mode window or make changes.

Alternatively, you can check for problems with the cleaning and security software.

Try to start the computer in safe mode Windows with network support (on the startup screen, press F8) as a test to see if that helps.
