Comment 9 for bug 229745

In my case, urlclassifier3.sqlite had grown to 33 MB in a couple of days. Then I switched off the phishing / attack warnings alltogether.

Although the problem is greatly diminished since the xulrunner update, this security function still eats up too much resources (occasional high CPU load plus I/O activity). Which makes surfing with Firefox less pleasant than it should be.

The strange thing is, that Firefox 2 has a similar function, which did not cause any such problems.
