At first I dunno if it`s this name in US/UK but in France it`s.
I got hard problem with my proxy.
I`m explaining that; I was using my internet browser " Opera " everything was cool and no problem.
A friend send me a Youtube link over Steam. It auto-opened me an other internet browser " FireFox " ( you may be asking; Why this french faggot has got 2 internet browser? I need Opera for somethings differents than Firefox, and I can`t really explain, but I need both internet browser. )
After watching the video from youtube, I closed Firefox, then, Opera, and gonna play to Counter Strike Source, on Steam. After this I turned off my computer, everything is okey.
I switched on my computer some hours later; Opened Opera for Facebook. I got an error message " Proxy or server temporary unavalable " or something like that. I tried a second time. Same... Strange? I tried some other site, like www.tx-gaming.net same. In the message error they said me to press F12 and to disable my proxy. Then I did. Opera is working. Now I open Firefox, to do something else. Same, so it`s my proxy. I turned it off. Now it`s working nicely. But on Steam I can`t change name or some other thing like see friends on/off line. But I can play... Seems strange... I can connect to Mumble, and not to TeamSpeak... I tried to connect to graphiix@tx-gaming.net ( my messanger account ) doesn`t working. I clicked on repair and it said me " Proxy + Principal Ports " with a little Yellow Warning.
I need your help guys to turn off the Proxy, it would be a great help for different reasons..! I was thinking about Judge helps if he`s okey... And if not someone good in informatik like Vash, Storm, Ironhide, Idk.
And I`m asking is that normal by " re-booting " my computer I got this problem with my Proxy?

Thanks to readers and helpers.
