Is there a recommended browser?

I'm currently using FireFox ESR (31.7.0) to view these forums and there are a number of aspects that seem rough around the edges in the way things layout, the way they draw and also in terms of performance. For instance, last night, when attempting to insert a jpeg into a post, I clicked on the add image button and just saw a white pane across my page with the above pictured text. It persisted for several seconds so I just assumed the feature was completely broken. As it turns out it's just slow to display.

I am wondering if there is a recommended browser where some of these issues might be mitigated or minimized?
