Hi! Yes, you can use 12-hour time format. Open up the Tabliss setting (click the cog in the top left corner), go down to widgets and expand the "Time" widget settings, the select the format you prefer :)
Works well but also overrides your homepage as well as the new tab window. There's no option to do ONLY the new tab window. So, while it does what it says it does, I can't deal with that limited functionality. 3/5
Love the UI, but I still need/miss my top site. It really quick/easy to has top site compare to your quick link widget. Hope you guy can bring those topsite into it, I'll come back and use it every day. Now I have to back to my ugly new tab but has topsite. Thanks!
Hi! Unfortunately that is a bug in Firefox itself, and there is no suitable workaround I can use. For some good news though, there is a fix coming in Firefox 59 for it!
