Not as good as SEOmoz blog Rated 2 out of 5 stars
* It drasticly slows down new tab opening in Firefox 12 even on fast computers.
* You have to go to Opensiteexplorer site to login each time you open Firefox. There should be an option to login automatically with login/password provided by user settings.
* Link hightlighting is buggy and impossible to trust.
* SERP overlay has fixed height (or it works so) so it can't fit in it's own DIV.
It's a weak promotion of SEOmoz Pro.
Sorry you're having trouble with the Mozbar!
We're sorry you're having problems, and would love to hear from you at seomoz.org, so we can help you troubleshoot these issues. To respond to your comments...
RE the log-in issue: We recently fixed a cookie bug that was logging people out inadvertently. We don't think it's specifically related to the toolbar. Hopefully that will resolve your issue. (I don't thing you're referring to the Login button at the far left side of the toolbar, but in case you missed it, check it out!)
We haven't been able to reproduce any link highlighting issues. We fixed a couple of specific bugs last summer, but haven't seen any since. Please contact us at firstname.lastname@example.org if you still have problems; we haven't been able to identify any specific bugs with recent testing, and we'd appreciate your feedback on this!
We've also experienced slowness with FF here in the office, but we're finding it isn't related directly to the Mozbar. I'd suggest uninstalling and reinstalling your browser and plug-ins, just to be sure they're all working as expected.
