Hi, It seems that with the last version that has been released for Firefox, developer edition, it is not possible to bypass the windows proxy settings, even it's configured in Firefox the option that connection don't use proxy. For me is a problem because I use this version (developer) as a complementary version for the normal one to perform some tests and find problems. At the moment I'm using the version, 90.0b1 (64-bit), and it works fine. It is possible to change something (reg value, advanced configuration, a file) in order to avoid this behaviour? Thank you so much in advance.
