1. When i take "url" manage groups from adress bar (for example moz-extension://8e9a54bb-e738-413f-ae0e-f28052cf45da/manage/manage.html) and make this url my home page, and then use hotkey or gestures to start homepage - manage groups starting, but tabs in groups deleting after transitions to other groups. Its sad.
2. Tab "manage groups" not deleting if i run manage groups and select other tab in current group, i forced periodycaly delet this tab. And why tab "manage groups" visible in manage groups?
3. Window "manage groups" does not remember window position and size, and why i cant maximaze window?
That's all for now, tnx.
