This is just a "heads up" warning.
I wasted 5 hours working on my PC, because of this.
The latest version of CCleaner (v2.35.1219) includes a Firefox "Session" cleaner.
I noticed that Firefox was "forgetting" my tabs (from my previous browsing sessions).
I had just been playing with the Firefox configuration files, so I figured that I had broken Firefox.
I spent about 5 hours, reinstalling Firefox and cleaning up my bookmarks (I have multiple profiles).
I tested my new setup and everything seemed to be working correctly.
My usual practice is to run CCleaner after closing Firefox (which I did after testing).
When I started Firefox again, all my tabs had vanished!
It then dawned on me, that it had been working, until I had "CCleaned" my PC.
I opened up CCleaner and I noticed that a new option, called "Session", had appeared in the Firefox section.
This option was deleting my session info and settings.
The moral of the story is, always check program settings, after an update.
