"Having to restart after installing an extension is another. Every time I see the request, I can't help lose a bit of respect for it."

Restart-less add-ons have been around for long years, so if you see one that wants you to restart Fx, you can blame it on the addon's creator (I know there may be some edge cases where it is a must, but those are pretty rare).

> One minor grievance I have with the Firefox console is the input line is all the way at the bottom. I quite like Chrome's approach of starting at the top.

This is such a small thing but it drives me insane (and keeps me on Chrome, among other things).

Yeah, I've enjoyed the last few years with not having to worry about restarting idk if I could go back...

>Having to restart after installing an extension is another

Because it's part of your everyday workflow to install extensions one after another, right?

> Having to restart after installing an extension is another

It depends on the extension. Only some (particularly, older) extensions require restarting.

Another one is not being able to use shift-home or shift-end to select to the beginning or end of a css property.

Wow, this drives me insane. I've always meant to file a bug report about this but I'm not sure if its supposed to be a feature instead. It appears to let you cycle through valid properties but I really wish it was assigned to another key.

File a bug if you want to request devtools improvements.
