I have 2 add on that don't work: when I try to log in on the Toggl button or when I try to import passwords to LastPass - nothing happens. There isn't an error or anything, just nothing happens. I also contacted the add-ons support but since it's 2 add-ons with the same problem, I think it might be Firefox that is the problem. I'm running Firefox Quantum 61.0.1 (64-bit) and I have already uninstalled and re-installed the 2 extensions and also refreshed Firefox and re-installed again. Nothing worked so far.
