Mozilla pumped out a release candidate version of Firefox 3.6.9 yesterday.
The pre-beta update is intended only for brave souls willing and able to have a poke around in the unfinished code.
“Please hammer on these builds mercilessly to make sure that things work well! If you notice things that worked in previous Firefox 3.6.8 and does not work in this release, we would like to know about it *right away*,” said Mozilla’s QA man Carsten Book.
As for what has been patched in Firefox 3.6.9’s RC, Mozilla has a full rundown of fixes here.
Separately, the open source browser maker pushed out a release candidate version of Firefox 3.5.12 on Thursday.
