This fixing for me if only im refreshing the page somehow (for example, as in the video, scrolling again).
Maybe FF settings matters, ive disabled many things to decrease RAM usage.
Yep, tried to reprocude on IE8. No problems there.
I have a specific preference file on my firefox, maybe that should explain causing the problem for me somehow:
# Mozilla User Preferences
pref("app.update.enabled", false);
pref("browser.search.update", false);
pref("extensions.update.enabled", false);
pref("extensions.update.notifyUser", false);
pref("extensions.pendingOperations", false);
pref("extensions.blocklist.enabled", false);
pref("browser.sessionhistory.max_total_viewers", 1);
pref("config.trim_on_minimize", true);
pref("browser.shell.checkDefaultBrowser", false);
pref("browser.feeds.showFirstRunUI", false);
pref("browser.rights.3.shown", true);
pref("extensions.shownSelectionUI", true);
pref("toolkit.telemetry.prompted", true);
pref("browser.places.importBookmarksHTML", false);
pref("browser.privatebrowsing.dont_prompt_on_enter", true);
pref("geo.enabled", false);
pref("browser.safebrowsing.enabled", false);
pref("browser.safebrowsing.malware.enabled", false);
pref("privacy.donottrackheader.enabled",true);
pref("dom.event.contextmenu.enabled", false);
pref("browser.tabs.animate", false);
pref("browser.display.show_image_placeholders", false);
pref("gfx.direct2d.force-enabled", true);
pref("layers.acceleration.force-enabled", true);
Im thinking that those things may stop loading the page:
pref("extensions.pendingOperations", false);
pref("browser.display.show_image_placeholders", false);
pref("gfx.direct2d.force-enabled", true);
pref("layers.acceleration.force-enabled", true);
But anyway, if its only me, then it doesent matter.
