Firefox full backup

[Kisianik]

Hi
I need to completely uninstall and erase my Firefox, as it completely unusable, nothing works there. Next, I will install FF back.
So I need to backup everything, including extensions, passwords, bookmarks (an easy job) and anything else I missed.
How to do this, the best way. I am not expecting an easy way, but a complete backup.

Please do not advise to use other browsers, I have already Crome, Palemoon,IE and a few others, each serves a particular task. so, stay on original subject.

Appreciate as always any help provided.

P.S. I can find all this info myself, but time is the essence, hence I am here seeking help to expedite reinstallation.

P.S. 2. My specs - Win 8.1 6 bit. Will erase Firefox with Revo Uninstaller.

C:\Users\<yourusernsme>\AppData\Local\Mozilla\Firefox\Profiles
Backup that folder, so called "Firefox profile".

That what I thought as well. So I just copy this folder into new installation and that is it? Would it make problems that I have now 64 bit and I want to install 32 bit, or it is doesn't matter?

Thanks

Another clarification needed.
My Firefox profile has 3 folders, do I have to backup/copy the most recent folder, or all of them?

Thanks again.

Success for now, will play and see if it solved (reinstallation) my problems.
