Mac OS and firefox last update ok. It happens sometime (very often) that firefox after open it, tells me to refresh or to run in safe mode. I try several steps to resolve this problem but without solution.

Now i have to install a plugin for firefox but can't install the plugin and configure it every day

Possibly Firefox is misreading the state of your keyboard: Firefox will display that dialog at startup if you hold down the option/alt key while clicking/double-clicking the Firefox icon.

If it's a "stuck key" problem, the resolution may require some trial and error. Sometimes jabbing the key several times fixes it. In other cases, wireless keyboards needed a fresh battery.
