Tor browser cant find Firefox server

Real N00by here!

I only want to use Tor [u]as a browser[/u], not interested at moment of doing anything more, until I get the hang of Tor.

So, I downloaded the Tor browser and installed on my Windows 10 Pro laptop.
Went through all the set up and everything was fine. I clicked on Start Tor Browser icon on desktop and the browser started - using Firefox.

The next day, after booting up, I went straight to start Tor icon, having no other browser running, I clicked on the Start Tor Browser icon again, the one I had used yesterday. But this time nothing happened. Clicked again, nothing.
I went to where Tor was installed, tried to run Tor from within Tor directory, again nothing started. Then, after probably 15 mins, the Tor browser appeared on screen.
I entered a website url to get Tor to search. Straight away I got the Problem loading page error tab showing Unable to find the proxy server. Firefox is configured to use a proxy that can't be found[I]. Funny, I don't remember setting up a proxy! Firefox runs OK, normally, so why does it need a proxy now?
So I...
checked the browser's settings, Options / Advanced / Network / Connection / Settings / Configure Proxies to Access the Internet / No Proxy tab, No proxy was already selected.
checked I had a working network connection (well I wouldn't be writing this query if I wasn't!)
checked firewall - the only firewalls I have (Windows and IOBit) weren't running (risky I know, but!).
I even used the option to reset Tor browser to default settings.
After all this it still came up with Problem loading page,... etc.

I shut down the Tor (Firefox) browser, then re-tried again to start Tor. The Firefox browser started again with the Firefox' search page opening.
I enter a random URL that hasn't been used for a while, to make sure it was no cached site.
Again, the Problem loading page error came up - [i]Unable to find the proxy server.
I checked the browser's settings again, Options / Advanced / Network / Connection / Settings tab only this time Manual proxy configuration and the SOCKS v5 and Remote DNS were selected.
So, I turned off the Configure Proxies to Access the Internet / No Proxy, then tried again.
Again the Firefox search page came up. I tried a search item in the search bar this time, and....
and again the Firefox Problem loading page error page "[i]Unable to find the proxy server appeared.

So, what can I do to use the Tor browser ???

Thanks in advance for any help.

When you run a Tor Browser, it automatically starts Tor in background, then waits for Tor to connect to Tor Network, and then starts a castrated copy of Firefox Portable, with special settings in it (Proxy:Yes, IP:127.0.0.1, Type:Socks5, ...). When you close Firefox Portable, it automatically shutdowns Tor (this also takes some time, mb several seconds or even half a minute on slow PC).

So you can face several problems:

1) Tor had not enough time to connect to the network before you closed TBB and started it again.

2) Firefox Portable sometimes cannot be started if "Another copy of Firefox is already running". So it just opens another window of "normal" Firefox instead, with default, "non-Tor" settings.

3) Firefox Portable tries to use Proxy, but Proxy is not answering (because Tor.exe is either not running or not connected).

first, sorry my english
