I've found Firefox looses most preference settings everytime I restart my computer.
This isn't a massive problem but it means I loose things like the homepage settings and custom settings in extensions (which means these need to be set after every reboot ).
I think this is partially linked to the windows scan disk which runs often when I restart my computer (mostly I think this is because I simply turn off the computer via it's power button rather than choosing shut down within Windows) and does things like truncating files and dealing with cross linking (not sure what either of those really mean but it does seem to target areas of Firefox and other programs which store preferences).
I'm also unable to save any image within Firefox. Choosing "save image as" opens the dialogue box to select where the file is downloaded to. Clicking save closes this box and the image is not downloaded (the download manager doesn't appear either).
Any ideas on how to go about fixing either of these problems?
