Even better just disable session restore entirely - Browser.sessionstore.enabled - Since Firefox 3.5 this preference is superseded with setting browser.sessionstore.max_tabs_undo and browser.sessionstore.max_windows_undo to 0. As I understand this feature is there so if the browser crashes it can restore your windows and tabs - I don't remember having a browser crash on me since the demise of Flash.

Other things than a browser crash can cause the browser to unexpectedly quit. For example, a battery dying, or the power going out.

Serious question: Is 12GB a day really going to make a dent in your SSD's lifespan? I was under the impression that, with modern SSDs, you basically didn't have to worry about this stuff.

If you can get a petabyte of r/w out of an SSD then 12 GB/day (of writes only) will exhaust the device in 228 years (1 PB * 1000 TB/PB * 1000 GB/TB / 12 GB/Day / 365 Days/Year).

If there is also an associated 12 GB/day of reads then half that estimate (unlikely to be equal due to the nature of the cache). Either way -- not a significant degradation.

Edit: Degradation or not -- i'd personally rather have my drive resources available. In the context switch from firefox the cache process could interfere with loading other data.

Right but that doesn't happen quite often either. Also if it does how important is restoring the tabs and windows? Probably not to a lot of people other than serious creators that use a web editor of some sort that'll lose work if the browser disappears. Even then it is flaky to rely on something like this. Much better to have periodic backups of whatever you're doing.

i'm not seeing these numbers, using I/O columns in Process Explorer. i'm running Nightly Portable with maybe 80 tabs open/restored.

Nightly Portable might have this particular setting changed, because the lifetime of random USB sticks is surely going to be much less than a real SSD.

i thought that too but the interval setting is at 15000 in the config, so maybe something else is optimizing it out?
