Is it possible to search my YouTube favorites using Chrome or Firefox without an extension?"
Can anybody that has Chrome and can actually do it, answer? Also, for Firefox (latest version of ff), only those that can do it.
I searched a while back and found a website or two that did but more recently i've not found anything and certainly nothing in the youtube interface, though i've tried many options in the youtube interface.
I'm going to respond to a comment for me to be more specific. A comment said "Please be more specific about the Web browser features that you are trying to use, i.e, if you are trying to search from URL / address bar or using the Find in page feature. Show what you have tried and what you found on YouTube, and each web browser help."
To answer the question of whether I am trying to "search from the address bar" . No i'm not, and I don't think there is really such a thing. Sometimes people when they type a search term in the address bar it does a google search. I'm not talking about that.
As for whether i'm looking for a "find in page" feature, no i'm not. Youtube doesn't show all videos on one page. A person could have 50 pages of youtube videos.
As for what i've found on youtube when looking for searching favorites, there is this video here here "How to find favourites on YouTube (November 2020)" It mentions that the favourites list is now under playlists. But it doesn't talk about how to search favorites.
There's another video "How To Find Your Watch Later Playlist On YouTube - Mobile & PC" by GuideRealm here And it mentions that if clicking on the three lines, then it opens a menu showing "watch later" and "liked videos".
So from those it looks like "liked videos" is the current name for "favorites".
Another video "How to see all YouTube likes if you liked over 5,000 videos" By Bhupinder Tube
Mentions that you can list all watch history https://myactivity.google.com/product/youtube?utm_source=my-activity Though that's not searching "liked"/favourites
There is a search there when looking at watch history, but I see no way to search specifically for liked videos.
And the video mentions that you can list all liked videos, https://myactivity.google.com/page?utm_source=my-activity&hl=en_GB&page=youtube_comment_likes
but doesn't show a search for it. And "find in page" / ctrl-f won't do it because it doesn't show all results on one page. You'd have to keep holding page down for potentially hours or days.
