I just spent WEEKS troubleshooting the crap out of this problem, and could not solve it. I was tracing stacks on Firefox.exe threads in Process Explorer, debugging memory dumps in WinDbg, running safe mode, trying processor optimized builds, reverting to FF 3.5.0, reverting to FF 3.0.13, swapping out my Sessionstore.js, etc. TONS of people on the Mozilla firefox support forums are complaining, there is an endless amount of threads talking about sluggish performance and problems scrolling, stuttering when entering text, etc. Only today did I FINALLY solve this with the browser.sessionstore.interval. Seriously, look at how many comments there are sympathizing with this fix: http://www.reddit.com/r/todayilearned/comments/9by73/til_firefox_backs_up_your_tabs_every_10_seconds/ Here's a guy who bought a new PC JUST because of this issue (he thought his PC was the problem.) http://lifehacker.com/5342636/how-to-fix-annoying-youtube-jumpiness-in-firefox http://www.ncwoodworker.net/forums/f57/firefox-trick-fixes-freezing-25512/ "I was blown away by the results." "it is incredible how fast it is." This issue caused me and thousands of others (tens, hundreds of thousands?) a huge amount of aggravation. I am very relieved to finally get this monkey off my PC's back, so to speak. Do you realize that this single issue is the largest Firefox performance disaster I’ve ever seen?

“I was blown away by the results.” “it is incredible how fast it is.”

This issue caused me and thousands of others (tens, hundreds of thousands?) a huge amount of aggravation. I am very relieved to finally get this monkey off my PC’s back, so to speak.

The nsISafeFileOutput stream would ensure that you don't get corruption in these cases, however. Firefox shouldn't block other applications from accessing the hard drive, but that really depends on your file system.

Could this cause session writes to stack up or does the code check to see if a write is already in progress? Would Firefox end up blocking other applications from accessing the hard drive in a situation like this?
