Currently the Breakpad symbol cleanup script doesn't touch non-nightly builds. This means that we leave old alphas and betas around too. There's probably not much value in keeping very old alpha/beta symbols, and they will start to add up eventually. For example: grep -v pre symbols.txt | grep WINNT | grep "3\.0" | grep "b[0-9]" | wc -l 10 grep -v pre symbols.txt | grep WINNT | grep "3\.0" | grep "a[0-9]" | wc -l 7 We currently have 10 beta and 7 alpha Windows builds from Firefox 3.0. (Really only 5 unique versions for each, but there are a few extra due to bug 599343.)

I think we need to stick the release channel in the symbol index filename, so I can distinguish betas from releases. There's also a bunch of historical beta builds that could use some cleanup. This is going to be really important for when we turn on rapid betas.

3 year check-in - does this still matter?

We'll fix this in bug 943492.
