Hello,
Could you write me email (admin@fastaddons.com) with more details please? I would live to investigate this.
For example, is your PC running all night? And do you have "Auto-reload" enabled in some of your dials? There have been cases when auto-reload would fail if monitor disconnects itself when monitor goes to sleep but PC is still running.
But in any case, addons should not be possible to crash the browser, so sounds interesting.
Please let me know.
Best Regards,

Hello,
Right click group name or open main menu and select "Edit group".
There you can change dimensions / layout.
The PRO feature for dial resize applies only to single dial. It should be less confusing in the upcoming release :)

This article should help with the dials recovery:

Hello,
Is there some error message?
Unless you are using some very old Firefox, everything should work.
Maybe this article will help:
