Freezing issues. Rated 5 out of 5 stars

EDIT: Thanks for the fast response. I wish other developers were so good at responding to these review sections. I've installed the latest version and will see over the coming days/weeks whether the issue has been resolved. I'll be back if the problem persists. Thank you.

I am getting a problem where (particularly after awakening the computer from sleep mode), I cannot switch tab pages by clicking on the tabs. I click on them and nothing happens; I stay on the current page (and selecting tabs in Firefox Panorama view causes Firefox to crash). I can however still switch tabs with the mouse gestures addon I use (FireGestures), so I know this is a tab interface problem, and not a problem with how Firefox is actually running behind the scenes. Apart from not being able to switch tabs from clicking on them, otherwise Firefox works fine when this problem occurs. The problem does not happen all the time, but does happen on seemingly random occasions. This is the only tab addon I have running, so I assume this addon is causing the problem. I'll wait until the next version hits and see whether the problem persists (I don't want to get on the development build cycle if I can avoid it). Restarting the brower always solves the problem (sometimes, putting the computer back into sleep and waking it up again also solves the problem), so that is what I will be doing for the time being. I do not just like using this addon, I need it. So simply disabling it is not a possibility. This addon is essential to frustration-free browsing for me, hence the five stars. Even with this issue I am having, it is still easily deserving of five stars. Plus I greatly appreciate how the developer resonds to this comment section.

This review is for a previous version of the add-on (0.3.8.7). 

try the new 0.4.0 version
