So when I start FireFox up I get just a blank window and not my last set of tabs. Reproducible: Always Steps to Reproduce: 1. Open a window 2. Quit Firefox 3. Launch Firefox Actual Results: I get a blank window. Expected Results: I want my last set of windows and tabs. I've been working around this my manually copying the sessionstore.js file somewhere before I quit Firefox. It appears to be updated correctly (all my newest tabs and windows are in there). But when I select "quit" or let Firefox restart to update itself or some plugins the file gets deleted. Interestingly, when I copy the sessionstore.js back after Firefox has quit and relaunched, it tells me that my browser was shutdown unexpectedly. If I force quit Firefox then it (perhaps obviously) doesn't delete the file and so I get my windows back the next time it launches.
Please reopen this bug if you're not having Shiretoko clear your private data at shutdown (of which sessionstore.js is part).
