Lightbeam freezes Firefox (consumes 100% CPU)

[antistress]

Hi, Great extension, thank you for bringing it back! One worry is that it usually freezes Firefox after some seconds. I've checked and then it consumes 100% of one of my CPU

If then I try to close the Lightbeam tab, it takes some (long) seconds before Firefox close the tab and finally returns the focus to the user. Thanks

I've encountered the same issue, except it's worse. My computer crashed after open the lightbeam tab

First of all, I love this tool - many thanks for maintaining it! I can confirm this problem when Lightbeam has been active in the background for a couple of weeks and the number of websites/URLs is quite high (I cannot say how high exactly, probably a few hundred). When I try to use Lightbeam's "Reset Data" button the browser starts working and sooner or later crashes, unfortunately without the data being deleted. My workaround is to uninstall and then re-install the extension, which deletes all data and then Lightbeam works like a charm. But of course it would be much nicer being able to use the tool without having to re-install it every few weeks. The original Lightbeam extension did not have this problem.

Thanks for reporting. I will see if I can at least figure out what is causing this issue. But I cannot guarantee a timeframe.
