5/5.

A fantastic add-on. Adds much needed basic functionality such as "multiselect", "move here" and "load entire playlist". Something that YouTube itself has neglected for years despite user feedback.

I can't stress enough how much easier it became to manage my 700+ video playlist on YT's horrendously designed mess.

do not work at all

It seemed to be working fine at first, but now I've just lost about 130 videos when reorganizing some of my most important videos into new lists. I have several lists with "Lessons" about stuff I work with. Now I have only a few videos left. This is so incredibly annoying.

Edit: I have edited my review. I still use the plugin and taking it shortcomings into consideration, it's still a useful tool.

Only needed briefly but was an incredibly helpful tool.

Absolutely brilliant. Only gripe I have is the pulsing donate heart, but if you have ublock origin installed you can hide it with a custom filter:
"www.youtube.com##[id^="msfy-donate-icon-"]"

Просто. Лучшее.

The extension seems to work fine enough for now. However, in the new bar at the bottom, right next to the donate button, is a horrid pulsing heart. As far as I can tell, this heart icon serves no purpose other than to be annoying. It is incredibly visually overstimulating. Seriously, why is it throbbing?

A must have add on
Thank you Pollux :)

This is in my top 3. WORKS! I assume creator in new version found ways to work around some YouTube limitations. "Select videos by title" filter is my way to create themed playlists from Watch Later. PLEASE, make SELECT BY AUTHOR too. And if possible - By Language.

I do not understand the bad reviews. The extension does not ask for important permissions and works perfectly fine for me editing my "watch later" youtube playlist. Very useful!

bro i love ur extension but the 3.0 version doesnt work for me anymore, i have my browser updated but i dont see the button to activate the extension anywhere on the website and i cannot select any video. I do have the extension enabled on the extension manager and i have restarted the browser several times. idk if im doing something wrong, hope u can fix it when u have the time to do so, thanks for the extension. pd: in my android tablet the extensions works properly so idk if its just a mozilla problem

The new version took some getting used to, but now that I've familiarized myself with the new action bar, options and the keyboard shortcuts, I like it.

Edit to add: If you have any issues with the three-dot menu in the action bar not working, you might have to disable a conflicting extension. That happened to me – I'd apparently installed another extension for managing YouTube playlists at some point, and while it was enabled, clicking the three-dot menu didn't do anything for me, but disabling the other extension seemed to fix the issue. I didn't think to mention this until I saw a different review mentioning the three-dot menu not working.

I love this extension, but I no longer see the checkboxes to select videos after the update. I will change to 5 once I can use it again.

This new version is a step down on multiple fronts.
You have to "turn it on" each page you want to use it on compared to have it on on select pages you pre-set previously.

I'm not a fan of the bar at the bottom.

And I liked having the numbers on the side with large playlists to easier reference them.

I'm hoping for a return to the previous style or the option to choose.

Started using 3.0, and it's a lot less usable than the previous version. The biggest problem I have is how the extension hijacks the Home, End, and arrow keys. Whenever I make a change in a playlist, YouTube unloads everything in the list after the 100th video and I need to hold down the End key until everything returns. With the update, the extension only scrolls to the 100th video when I press End, so I have to turn the extension off, hold down End until the rest of the videos load, then turn it back on. It's also annoying if I try to use the arrow keys to scroll up or down a little and it just jumps back to the whatever video was highlighted. (EDIT: I think End still works to scroll, but it takes a moment to load and there isn't a spinning wheel to indicate anything is happening)

There's a new confirmation prompt when I try to remove several videos at once, which adds another step.

While clicking anywhere on a playlist item to select it is easier and faster than clicking a box, this disables drag and drop, which is useful when I want to move a single video into another location. It's easier to click and hold, scroll up, then release than it is to click, scroll, right click, then click move down here. Another added step.

I also miss the videos being numbered, which gave me easy reference points to find when moving through a large playlist.

The center bottom location of the toolbar blocks the bottom video, and having to click the three dots to use functions I use all the time, while three functions I rarely use are always visible. I would like all functions visible or customizable, and the bar should span to the left of the Multiselect button, blocking the search bar, which I wouldn't be using when organizing a list anyway.

I hope the next version is as helpful as previous versions.

EDIT: Lowered rating to 1 star for the immature developer response to legitimate, constructive criticism. All of these things can be fixed and more people would use this extension if they were, but if this person would rather encourage me to uninstall than make improvements, then I encourage everyone dissatisfied with these changes to look elsewhere, as this is apparently the final version.

About 3.0. Normally, I was able to confirm that it works on accounts that are not in use. The account has no playlists and no channels registered. However, it is not working on an account that I normally use. I can even select videos, but when I click on the three point reader in the menu at the bottom of the screen, the menu is not working. This is an extension that I have great expectations for improvement.

Really great! My only suggestion would be to bring back the option show the video index numbers in the subscription page. Great extension!

Great™ — Multiselect has become an essential YouTube feature for me. Google, if you’re reading this: buy Pollux’s code and integrate it.
