weird problem with user notifications

[replica9906]

I have this weird problem where in the user control panel, whenever I change settings and re-open them via the UI the options are checked one by one. They are not reverted, they get checked or unchecked...

I have tried that, both as an Admin and as a regular user, on Firefox and Chrome browsers and both work fine.
And I tried both classic and new layout as well.
Try logout/login and/or delete your forum-cookies and then try again.

I managed to pinpoint that this is an issue with Firefox. It did not happen on Safari. I could not find out what on Firefox causes this, so I will just use safari to make changes to my notification settings. Thanks a lot for your help!

Just in case, I'm using Firefox 115.19.0esr (Extended Support Release) on a laptop with W7.
