Hello, I am still running Win7. After this morning reboot, firefox did not start, messaging: "Der Prozedureinsprungspunkt "sql3lite_database_file_object" wurde in der DLL "nss3.dll" nicht gefunden. After that a message windows says: "Couldn't load" XPCOM. I tried to reinstall firefox downloading it with another browser, but the installation (I am now working with) seems to be somehow parallel, i.e. I don't have my profile and extensions, passwords, etc. And the look ist different. Thanks in davance for any help.

In the meantime, I have figured out that the renewly installed Firefox is located in C:\Program Files\Mozilla Firefox, my old (not working) one in C:\Program Files (x86)\Mozilla Firefox.

Can I somehow tell the installer to use C:\Program Files (x86)\Mozilla Firefox instead of C:\Program Files\Mozilla Firefox? If yes, will this affect my profile?

Can I import my profile to my new installation alternatively?

Thanks again.

Ok, the other Browser simply installed the 32bit-Version on my computer. Downloading the 64bit version and choosing the installation path solved my problems.
