Can't log in another Google account on Firefox

more options

Hello,

Recently, I can't log in to another Google account on my Firefox browser. On google.com site, when trying to log in on another account by Account button at top right corner, it doesn't effect when clicking even though bottom left corner show detail link. It happens with Apps button next to Account button as well. I'm using Firefox version 70.0.1 (64-bit). It make annoying on me quite much cause I often work on more than one Google account.

I has IDM Integration Module, uBlock Origin and Ace Script add on. I realize IDM and uBlock add on but I don't know what is Ace Script. I tried to remove it but it can't (only disable it). I also tried to disable uBlock Origin but problem can't be fixed.

I tried uninstall then re-install Firefox. Problem remains. More information: it can show gmail properly when opening by Firefox: some buttons doesn't show icon even if I can interact with it when clicking on. Attachment is an example.
