WWorks fine om my 64-bit Ubuntu box Rated 5 out of 5 stars

with both FF 8.0 and Nightly 10.0a1 after installation of the Add-on Compatibility Reporter add-on. Note also that the latest Nightly seems to have at least partially resolved the memory-usage problem, even with 10-20 tabs open, usage doesn't go over about 700 MB....

This review is for a previous version of the add-on (1.6).
