It works. And for anybody, who says it doenst work: Scrol down to the comments, and in this section you will find a arrow button in the top right corner (rigt over the bar, where you could write a comment)

Loving it, not sure why it's not working for other people, I have like 10 other YT extensions and its working flawlessly. The only time it doesn't (which is my one and only complaint with it) is when I open a YouTube link to load in the background which makes it just not appear for some reason, but I'm not sure if that's on the extension or on the way firefox works.
5 stars regardless tho, exactly what I was looking for!

Doesn't work sadly

Just click a button. No configuration required. It's as simple as that.

Stopped working for me on 09/27/24. no other extensions installed

doesnt do anything. waste of time.

Doesn't work

I like it will be super if you could add popup funtionality to the comments

Works nicely

EDIT (Jan 5, 2025): NOT WORKING

It seems this add-on does not work well with tabs open in the background. I often browse youtube by opening vids in other tabs, then going to them when needed.

Doing that however, I see that this add-on does not load on those inactive tabs and comments are still on the bottom. The only way the addon works on those pages, is if I refresh the page.

Sidesy emerges as a savior from YouTube's layout blunder, adeptly relocating comments to the side of the video. This intuitive Firefox extension tackles the frustration of missing video content when scrolling down to engage with comments, a glaring oversight in YouTube's design. In the rare instance Sidesy requires a reset, a simple off-and-on toggle followed by a page refresh effortlessly does the trick. This minor troubleshooting step is a small price to pay for the seamless engagement Sidesy reinstates. Earning a stellar 5/5 rating, Sidesy is a must-have for those seeking a rich, uninterrupted YouTube viewing and engagement experience.

Seriously amazing extension that completely elevates the youtube experience to another level. I don't think i would be able to go back to the old comments layout since i feel as if I miss too much of the video that is playing in the background while I'm scrolling down looking at the comments. The only thing i would like to be able to change is the width of the comments window (even though I'm not sure if its even possible), but with that being said its not such a big deal and i still love the extension. 100% would recommend to my grandma.

It's good to use

can you make the screen split line adjustable? current comments section is too wide.

i mean like this one, this has a draggable divider to resize the video section and the comments section

Sometimes works, when it doesn't I have to refresh the page until it does. Otherwise, great.

Simple and Neat, works perfectly.
Would be nice to have an option to both hide the movement button (keeping it to the plugin setting), and to have it move there by default instead of having to select it every time the YouTube page reloads.
All in all, great plugin!

It's nice if you're not in wide mode but i mainly watch videos in wide mode defeating the point of using it but still nice to have for when you're not in wide mode

Just works, looks great. I'd like an option for it to just automatically be like this.

Works great
