We can personally report that for Windows Vista Ultimate Edition the new Firefox 18.104.22.168 is causing our computers to periodically crash. The first two times it crashed it gave us a nice BSOD, while the third time it crashed by itself, along with several open brower windows we had open for research.
Until Mozilla fixes this, we are stuck with Exploder or must use an alternative, such as Opera or even Safari, but not certainly not Firefox. We lost some serious work because of the unexpected crashes.
We urge Firefox to promptly address this. We are using Firefox 22.214.171.124 in the meantime.
