1419424 - YouTube hangs tab when populating the sidebar with subscriptions

Status: RESOLVED INVALID

(Core :: Layout, defect, P3)

Description

[Rodrigo]

Attachment: aboutsupport.txt

STR:
1. Get a YouTube account with subscriptions (I have a lot of them, so many that YouTube throws a "500 internal server error" for some reason)
2. Load https://www.youtube.com/feed/subscriptions
3. Notice how the page hangs for 5~10 seconds while populating the sidebar with subscriptions

I don't know when this started happening, but it was at least a week ago.

Rodrigo check my last replies in bug 1419833 for a workaround for now. :)

@Daniel I'm currently just blocking the subscriptions section of the sidebar with a uBO filter: 
www.youtube.com###sections > .ytd-guide-renderer.style-scope:nth-of-type(3) > .ytd-guide-section-renderer.style-scope:nth-of-type(1)

This is obviously a workaround and, since I don't use the subscriptions sidebar, I'm fine with it.

I prefer my easier (and more beatiful dark orange theme) workaround with the addon :P Thanks though Rodrigo!

This issue seems to be fixed.

Ah that is why I got YouTube's notification bar "it is better now", instead of simply writing "We fixed the new theme" or so... But that is YouTube :P

Fixed by YouTube.
