Fix #5527

[bsclifton]

First run through on a Mac

The bad

noticed the home button is not horizontally aligned:

the stop button I think need to go left by 1px

The good

Here's what does look great:

• rest of buttons 👍
• using black w/ 10% alpha instead of gray on footer for add/edit bookmark hanger
• new brave button
• new tab button looks perfect! 👍
• new gray color on newtab much easier to read (time saved, etc)
• new height for extension button looks good! pocket not huge anymore 😛

thanks. I'll fix...

@bradleyrichter This is how it looks on Windows. The mouse hover isn't very prominent. Plus the stop button looks a little lighter than the refresh and the home buttons

[jkup]

Colors look great! Agree with other fixes on here then we're good to go!

[bradleyrichter]

ok, all of the above should be fixed but we still need a windows review to check the button alignments.

++ merging.

@bbondy @bsclifton @jkup This will need windows adjustment unless all planets aligned.

Stop loading SVG is still not fixed on Windows
Refresh SVG is still not center aligned

Clearly visible when zoomed in

#5737 should fix the alignment issue.
