Thank you, I understand why everyone is mad. It's free to use for a long time. I respect your decision. At first I wanted it to be just a donation, but the country I live in doesn't accept donations whether I use paypay or stripe.

Sorry to make you think it's a lure, but it's not like that. And it's been free for a long time. It's not just recently. As i get older, i need to spend more money. After I updated the code I decided to add it. For the time I spent doing it

It's not a new permission. It's the same permission from manifest v2, but in v3 it needs the user to enable it themself.
And I'm not forcing you to use it. There's no need to tell me when it's not what you want.

update extension from using manifest v2 to v3, which in the future v2 will have to be terminated
Normally, when installing the extension in v2, it will be required during installation, but in v3 it will be an optional option that needs to be turned on manually. This permission gives the right to inject code to create buttons on the Youtube page.

on the "Zoom / Mirror" button displayed on YouTube Player at the bottom of the menu, there's a Mirror button. You just don't see it. If it's not FullScreen, you have to scroll down.

Now you don't have to scroll. Just need to update to v5.3.3. I let it all show.

It's at the bottom of the menu. If you don't see it, scroll down.

Updated to v5.5.1
- Add Shortcuts for mouse
- Add option to enable/disable fixed shortcuts

Add Zoom, Move, Reset with mouse
Using the shift key, ctrl key is not suitable, there will be other problems.
You can adjust the speed in the options.

I just now understand your problem.

Must delete or change shortcuts in Manage Extension Shortcuts.

Updated to v5.5.1
- Add Shortcuts for mouse
- Add option to enable/disable fixed shortcuts

In option > enable shortcuts for > try to disable Fixed Shortcuts
If it doesn't work, try disable everything again.
Finally, if it still doesn't work. Try deleting in Manage Extension Shortcuts too

Reply to me again if there is still a problem.

Updated to v5.4.8
- Fix autoplay problem

I'll inform you, this one can't be fixed.
In theater mode, there is a problem when pressing rotate for the first time that it doesn't fit properly (while in default view / no problem in fullscreen) which is caused by the width and height of the image in theater mode.

Ok, how is that account different from the others? I tried switching my google account but it didn't have a problem. Try changing the language or changing the theme, no problem.
I don't know what the cause is, I can't fix it. If you know the cause then please reply me.

I've checked both Windows and Mac in the latest version (v110.0.1), but it doesn't have a problem when pressing the zoom button and the menu doesn't pop up.

Please remove this add-on and install it in the latest version (Upload Today v5.4.7)
*** Not update. Remove it > Close Firefox > Reopen Firefox and install the add-on ***

I don't know what caused it. But I reworked the code sequence of the zoom function. Hope it solves your problem. If the menu still doesn't pop up Try using shortcuts instead.

HI. i have checked. It still works normally.

Can you try disabling all addons to just this one? If it works, it means some of your addons are in conflict with this one.

If it works then please reply me. I want to know which addon it is so I can check and fix it.

If not, what version of firefox are you using?
Previously, there were people who had problems with this zoom function as well because they were using Firefox Nightly, some versions that had problems.
