ZennoPoster is using a FireFox BuildID from 2013...MAJOR footprint

[lukas76]

I'm using ZennoPoster and opened this website in projectmaker: http://browserspy.dk/showprop.php

There is a hardcoded BuildID that Firefox has for ALL versions of FireFox. This build ID is like extremely old think 2013.
That buildID is: 20130215130331

I opened the same webpage in a real copy of FireFox and got this BuildID: 20150630154324

Now I know you "can" edit the buildID by overriding it in Xulrunner.js if you know where to look and I did this and tested it again on the above website and got the same BuildID as before editing Xulrunner.js 20130215130331.

You too can test this yourself if you wish, this is a MAJOR footprint that needs fixed asap.

Any website could have blocked us instantly just using this footprint alone.

Just paste these two lines to C# code action

instance.SetHeader(ZennoLab.InterfacesLibrary.Enums.Browser.NavigatorField.UserAgent,"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0");
instance.SetHeader(ZennoLab.InterfacesLibrary.Enums.Browser.NavigatorField.BuildId,"20150513174244");

Just tested these, thank you! Works flawlessly... Why isn't stuff like this more common knowledge?

how do you find the buildid for the useragent you use???

Maybe somewhere there is a complete list of Firefox builds and releases. But I use add-on compatibility reports like this https://addons.mozilla.org/en-US/firefox/compatibility/reporter/{c07d1a49-9894-49ff-a594-38960ede8fb9}
This is sufficient for my purposes.
