I followed the documentation in https://developer.mozilla.org/En/Developer_Guide/Source_Code/Mercurial and downloaded FF source with:
hg clone http://hg.mozilla.org/mozilla-central/ src
How can I switch to the FF3.6 'branch' or 'tag'? The documentation said
hg clone http://hg.mozilla.org/releases/mozilla-1.9.2/ 192src
but I don't want to clone both FF main and FF3.6 twice?
This question is related to
mercurial
Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.
UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.
