GeckoFx loaded page grey

Question

I have GeckoFX 45 in my project and use it as a web-scraper and it loads YouTube page and gathers info like title, number of comments, top viewed video, etc... After I did not use this tool for over a year but all other web is loading when I debug it. In the browser, I have this code even if I try to comment all, it still cannot load youtube page and it is grayed and we can't see anything.

GeckoPreferences.User("general.useragent.override") = UserAgent
GeckoPreferences.[Default]("extensions.blocklist.enabled") = False
GeckoPreferences.User("security.warn_viewing_mixed") = True
GeckoPreferences.User("media.navigator.enabled") = True
GeckoPreferences.User("media.navigator.permission.disabled") = True 'False
GeckoPreferences.User("plugin.state.flash") = True
GeckoPreferences.User("network.http.sendSecureXSiteReferrer") = True
GeckoPreferences.User("browser.xul.error_pages.enabled") = True
GeckoPreferences.User("browser.screen_resolution") = 1
GeckoPreferences.User("dom.max_script_run_time") = 0
GeckoPreferences.User("network.proxy.ssl") = True
GeckoPreferences.User("network.proxy.ssl_port") = True
GeckoPreferences.[Default]("extensions.blocklist.enabled") = False

I'm having the exact same issue and I asked about it on the [BitBucket repository for Geckofx60.64](https://bitbucket.org/geckofx/geckofx-60.0/issues/68/only-youtube-not-loading-in-geckofx6064). — Peacock, Jun 16 '19 at 20:32
@Peacock i found the way, just change the useragent to the latest ones for example this ua works: Mozilla/5.0 (Windows NT 10.0; rv:37.0) Gecko/20100101 Firefox/37.036 I hope it helps. — PavelRak., Jun 19 '19 at 16:08

I can confirm the behavior. If you specify an older or inconsistent string you get either blocked (browser no longer supported page) or the clips greyed out view.

However, if you specify no UA or override it with a proper current UA string it will work, e.g.

GeckoPreferences.User["general.useragent.override"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0";
