I only found this in one place so far, but it seems likely.

Per the article, the final FF 115 ESR release will be required on Mojave from September 2024.
I've mentioned before how this would be coming. Mozilla is probably expecting XCode to set the default minimum MacOS target to 10.15 in the next year or so.
Right now the minimum MacOS for PaleMoon browser appears to be 10.7, so there's still some hope for the future. (The values are 10.12 for current Firefox, and 10.13 for Chrome.)
