User agent override for Youtube

[Samson]

I'd like to suggest an update to the about:config useragent override currently being used for Youtube.

Currently it is set to this:

Code: Select all

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0 PaleMoon/28.5.0

This does not allow for the use of the dark theme on the site though so I'd like to suggest updating it to this instead:

Code: Select all

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:62.0) Gecko/20100101 Firefox/62.0 PaleMoon/28.5.0

That will let you use the dark theme. Unfortunately any agent using a Gecko or Firefox version >= 63 causes all of the video preview spaces to load blank so it can't go any higher than that because of silly Google and their aggressive useragent sniffing.

Feel free to change it yourself but not likely gonna happen.

Our UAO is set to 42 for a reason, namely the use of the previous UI iteration of YouTube that doesn't use Chome-focused code (which is slow and CPU intensive on anything else)

I have changed it myself. I just figured it would be nice to update it for everyone else too. Bummer that it causes slowdowns for some people. I'm not getting that myself.

Not just some. Everyone not on chrome/chromium based browsers.

I use the new YouTube interface to get the default Dark Theme in YT so I changed to a different user agent than what comes with default Pale Moon. I get the same results as you do. No slowdowns for me and this is with using a 2010 year model HP desktop tower computer with an Intel i7 processor, 2.80 processor speed with 16 GB of memory.

No, not everyone is affected, but a number of people are. Hardware seems to matter.

I have a problem using the new design. I find it excruciatingly slow with CPU usage that fluctuates between around 30-70%.

When the new design was rolled out in Sept 2017, the UA override was initially changed to have PM use the new design. This produced feedback from people who had problems using it, and after some examination the UA override was changed back. The discussions can be found/read by searching the forum for: youtube new design

If you are on an i7, Ryzen, or other "enthusiast" CPU, you'll likely not notice. but that's not what most people are running, and there were clear complaints about it. Do a forum search.

Hi all,

I'd like to have either a builtin function or an add-on, which would add "&disable_polymer=true" to every youtube url. This enforces the use of the old youtube design. It usually helps, if youtube is unbearably slow for you. Maybe youtube will eventually remove the old design completely from their web site, years ago such a step was announced, but so far nothing has happened.

There are add-ons like "youtube classic" or "Disable Polymer on YouTube" for FF, but unfortunately they are all webext now, and I can't find an old version anymore, that would work with Pale Moon or SeaMonkey. If I knew how to develop such an add-on, I'd do it myself.

kind regards,

Use the javascript scratchpad to set a cookie set it expire in the year 9999. The Internet will tell you the code.

You can also do it to always have the wide version on the older layout.

As an aside, I have a Ryzon system and new youtube still runs like shit, even in chrome.

Pale Moon's user agent already forces YouTube to run in disable_polymer mode, you can use Pale Moon's user agent to disable polymer in other browsers without an extension

This is the user agent I use "Mozilla/5.0 (X11; Linux x86_64; rv:60.9) Gecko/20100101 Goanna/4.2 Firefox/60.9 PaleMoon/28.5.0"

Also you can get a dark mode on the old design with this user.css theme https://awau.moe/6XapUff.css
