So, today Mozilla released a new Firefox version (119), and out of curiosity I decided to check on how does Librewolf took the last time to update it, and I compared it to Mullvad Browser, since there are a few people here that seem to have an erection when they talk about that browser.
Mozilla released FF 118.0.2 and ESR 115.3.1 on the 10th of October.
Librewolf which is based on the non-esr version, got updated on the 12th of October (so, two days after).
Mullvad Browser 13, which seems to be based on the ESR version of FF (this by itself makes them a bit different, but okay), was updated on the 13th of October (so, three days after).
I guess that the speed of the updates is not so relevant in this case, right?
