Hello,
Firefox 70 has just recently hit the stable release, and it updates a lot of stuff, but the update I'm talking about here is the new logo.
The portable Firefox apps (Firefox, Firefox Beta, Firefox Dev, Firefox Nightly) still use the previous logo, so these apps should change their logo as soon as possible, preferrably when PortableApps.com mods update the said apps.
How many times they change logo for past year? Its really annoying.
7 logo in 17 years https://logos.fandom.com/wiki/Firefox_Browser
Portabilizing application... 14 at the moment
It was already in the works for this round. 70 was mirroring when you posted this
Note that ESR is still using the old logo on purpose.
Sometimes, the impossible can become possible, if you're awesome!
