Just out of interest, how many people run the "release" version of Firefox?

I'm currently using Firefox Developer on the latest auroua update channel version ( 70.0b3 ).

I haven't really expereienced any problems and am only vaugely aware of new things from time to time. Actually mostly I'm not sure if I'm noticing something new or something that's existed for a long time. Like for instance the other day I put in an address in the address bar and it gave me a "switch to tab" option because I already had that open in a browser window, I swear that's new, but I'm not sure!
