"Almost as high" is a strange way to put it since its popularity has been dropping steadily over the last decade. And Edge market share is only going up.
Now that Firefox is no longer in the top 3 (in the Western market, further down world-wide), we can expect it to lose relevance even more quickly. Especially since Mozilla leadership has studiously avoided any effort to differentiate themselves from from Google/Chrome. They missed a huge chance to become The Privacy Browser that puts users in control of their web experience when Google and Facebook recently got all that bad press about privacy violations and monopolistic behavior.
