Rated 4 out of 5 stars

Although the add-on is excellent I am facing the same problem than before (I already included a comment here some time ago). There is a memory bug in the XPI. I do not know why but once the add-on is active TB starts to consume 20% of CPU as average... if I use Alert Switch it does not. I think that there is any process related to XPI that it seems to be checking something? but CPU increases to 20 - 22% of total and it should be not.

This review is for a previous version of the add-on (0.16.1).

0.15.3 works as fine as 0.15.2... but I found that both have huge memory leaks and CPU hungry. When mailbox alert is working takes almost 25% of CPU, and after few hours of operation RAM increases to values from 450Mb to several Gb! until crashes TB. Any idea?
