Gmail - Firefox to load most used account.

My esteemed listmates,

I have more than  one gmail account.

When I open Firefox it always opens to a lesser used gmail so  I have wait
for that s to load then have to right click on my profile to see the most
used gmail and then click on that gmail to open that.

Is there a way to set gmail so that my most used gmail loads first?

I've received odd results when I Googled this.

Thank you so much.
