Resolving Firefox build dependencies on LTS distros quickly becomes an annoying task.
Thankfully, with enough patience we made it and got #Abrowser 139 available for #Trisquel 11 which had been available only for T12 for some time.
We should be ready to keep track on some further releases faster as we've solved the dependencies 'til we need to figure them out again. 😅
But that's just life, so enjoy and don't forget to report issues.
Cheers!
