Hello,
Could you send me email (admin@fastaddons.com) with more details?
Because I'm not sure I understand the issue.
Note that restarting Firefox doesn't preserve addons tabs, so dials page is usually closed after restarting:
https://bugzilla.mozilla.org/show_bug.cgi?id=1742771
I'm not sure this helps, but you can press F4 to open dials page, or "Alt + o" to open quick search.
Best Regards,
Juraj Mäsiar
