1. I'm using Firefox portable latest version.

Nearly all addons stop working every time I restart Firefox. I have to manually disable and re-enable each addon to make them working again.

It takes considerably long time the first time I load the first website after I restart Firefox. Also it may suddenly hang after using for a long time.

What's up? How could I fix them?

2. I would like to transfer all settings, cookies/local storage, addons (settings and files etc.) to a fresh copy of Firefox portable, to see if those issues would be fixed. What should I do? Which files do I need to backup?

Thank you.

When a push notification is received, the display turns on (via DPMS). Is it possible to get rid of this behavior? Is there some configuration option in Firefox in about:config? I can't exclude that it's not Firefox doing this, but I'm guessing it is.

Why does this remove the entire history of a website? It doesn't make sense. I just want to remove what history it has made today. This doesn't make any sense... Not at all and the more I explore Mozilla, the more confusing it is despite I have used the browser for more than 5 years.
