Mozilla has patched a memory-consumption issue in Firefox caused by leaky add-ons, but has found the patch may not be 100 percent successful.

Mozilla developer Nicholas Nethercote tested a patch by fellow developer Kyle Huey for six add-ons, including McAfee SiteAdvisor 3.4.1, and found the patch reduced incidents of 'zombie compartments'.

However, the patch also caused code built with the Mozilla Add-on SDK to "leak badly". Developers are discussing the issue, Nethercote said in a blog post on Monday.
