I'm still running FF 12 Portable, and all was still going fine until I booted up this morning. Certain select but important items just seem to be gone:
All Cookies
The Cache.
All History from just the last few days -- older History still there.
(However, Saved Passwords were untouched.)
Javascript functionality appears to be gone.
Far and away, the most critical thing I'm noticing is that the set default under 'When Firefox Starts', which I had set to "Show My Windows and Tabs From Last Time", this setting is now greyed out and cannot be re-set. How can I get this back ? Is there a fix I can apply in 'About:Config' ?
Has anyone ever seen a problem like this ? The only changes since yesterday I can think of that could conceivably have "eaten" these FF Portable components are that I ran an Avast Boot-Time Scan before the system fully booted up (but that is supposed to give you file-by-file control over anything you decide to zap), and the No-Script Extension updated itself to v. 2.4.6. But I think those are both long shots.
I may just have to reinstall FF Portable, in order to restore as much as possible of what was lost.
Here's a related question. There is a page online that shows all the important files belonging to regular Firefox, what they are, and where they reside. I'd really like to have a roadmap like that expressly for FF Portable. Otherwise, I have just minimal clues as to where the Javascript etc. lives.

The same files as Firefox reside in FirefoxPortable\App\Firefox. And the same files as your local profile reside in FirefoxPortable\Data\profile.
Just install 13 over your current install as you should absolutely not be running 12 anymore (known security issues). Back it up first just to be safe.
Sometimes, the impossible can become possible, if you're awesome!
O.K., thanks -- have now done so and am in the process of walking it back to the prior functionality. It seems that some settings (starting with 'Private Browsing') must have gone awry -- though not by anything I changed -- and this accounted for most of those anomalies. It also looks like I needed to update some other things, and I need to read up on the setups for Java | Shockwave | Flash to have them work for the portable iteration of FF.
