Since this morning, i'm not able to do anything related with mouse / point-and-click when Scratch is fulscreen or inside the editor, meanig that:

- I can't use the bottom project control buttons, including “exit fullscreen”
- I can't do any point-and-click inside the projects in fullscreen
- The whole editor is absolutely unusable and broken

This might be linked to a recent update (yesterday with an auto-update), but I didn't have any problems after the update.
Waiting for a response, I'll try downgrading and see if it's ok.

——————————————————————————————————————-
My browser / operating system: Windows NT 10.0, Firefox 55.0, Flash 26.0 (release 0)
——————————————————————————————————————-

EDIT: The error seems to be linked to Flash, I'll try downgrading..

–> Nope, it's not that. I downgraded to Flash 25.0 and it changed nothing.
So it could be a -Scratch problem or a -Firefox problem, but I don't think the second is rigth…

PLEASE HELP !

Sorry, but recently people have been experiencing problems (mainly in the editor) while using Firefox versions 55 and higher. I suggest you downgrade or switch browsers as it seems to fix the problem. I've only seen two people using Firefox 55 without a problem, but the only one I remember is asivi. asivi never seems to have a problem, and they insist that it's to do with their browser specs and applications, but I think you should probably just downgrade

All those reports about troubles with Firefox 55 sounds really strange to me. Just waiting for someone saying something more than the editor and other stuffs are not working.

Hmmmm. How do you downgrade firefox ? I already spent hours searching for the Flash downgrade, and I won't restart xD

Go to here, press CTRL + F (Or Command + F on Mac I think) to open the search thingie and type in 54, then click on the link. Be aware of the warnings on the website though;

Though I will say that nobody else seems to have any security problems after downgrading
