Ever stumbled upon one of these? Blank YT pages. Usually they show an error to let you know what's up (or down), but sometimes...

I wonder if this one notice really complies with the GDPR...

Hi,
 
Because of minimal usage, we will no longer be supporting private messaging in Creator Studio.
 
The capability to send and receive private messages will end on July 9, 2018. All private messages will be deleted on July 9, 2018.
 
While you won’t be able to send or receive private messages in Creator Studio, you’ll still have these options for communicating with YouTube users.

...and that's it. That's all they say. Not even a 'kindly' or 'best regards'. Just: kill the feature. Goodbye.

...and this is what happened! :D Wouldn't mind if more studios give this a try, though it definitely works best the first time. Props on an anti-piracy initiative well done!

Wonder what this is all about.

I'm still using the Fox. It's better now. I found some tweaks. I browsed quite a few guides, and found out that quite a few old options no longer apply in the new version... but some still do! And they help, a little, so here's a little list of those for those of you who might need them.

For starters, type in about:config in your address bar, and then experiment (at your own risk) with setting the following:

browser.download.animateNotifications to False
security.dialog_enable_delay to 0
network.dns.disableIPv6 to True
browser.tabs.animate to False
browser.display.show_image_placeholders to False
browser.sessionhistory.max_total_viewers to 0

For finishers, type in about:memory in your address bar, and 'Minimize memory usage'. This should minimize memory usage.

A few other things I've been doing a long time now that speed things up: keep any extensions you don't need disabled by default, clear your cache and history every once in a while, don't let the browser add-on list get bloated, and if all else fails: about:support. Reset the browser.

Resetting the browser will reset some things, of course, so use that as a last resort if you have settings and history you'd like to save. It's been a while since I last did that. For now, these tweaks seem to be working pretty well.
