Not sure if this has been covered before, but pressing / to open the search box on Discourse also opens Quick Find on Firefox. Can we change the key to something else?
Are you saying that the shortcut opens both the Discourse-internal search box and Firefox’s in-page search at the same time (which I cannot reproduce), or that Discourse hijacks the shortcut so it only opens Discourse’s internal search (which is expected behavior)?
I can reproduce that, in Firefox 46.0.1 on Ubuntu Gnome 16.04.
Oops. Actually, I can reproduce it too, I was just looking in the wrong spot (Chrome really got me used to the top-right corner) 
I’m on Firefox 51.0.1 (64-bit) installed on opensuse and can reproduce this bug.
Actually, quick search opens for all shortcuts 
I am using Firefox nightly v57.0.a1
When I press /, both Firefox and Discourse search open.
When I press Ctrl+Shift+s, then the Firefox Webtool Debugger and the Discourse search open.
Some refactoring has been done recently though.
ouch, did not test that this does not clash with firefox… will see if I can properly hijack it.
Why was Ctrl+Shift+s introduced? Are there any other apps using that combo for search? What about ctrl+F for find?
It came up here https://meta.discourse.org/t/how-about-mentioning-topic-feature/7350/37?u=jomaxro
Short answer, finding keyboard shortcuts that work in all browsers and all keyboards is hard!
I think we ended up picking ctrlaltf which seems to be holding up.
