Thread:Project:Support desk/To launch mw-config more times

I'm installing extensions in my wiki (1.19.2) and some of these ask to launch an update. So I start mw-config / index.php but if after a little time I have to launch it again, the message tell me always that the installation is finished (even with the cache of the browser clean). So I have to start it in another browser, but then if I need another update I must use a third browser.

Is there a manner to launch it more times always in the same browser?

Thanks in advance
