Chrome/Firefox: Disable keyboard shortcuts on websites

Question

I am using Outlook Web Access in Chrome and Firefox. On OS X, the webpage uses the keyboard shortcut Option+S for sending off the email. Unfortunately, on OS X the same shortcut is usually used to type the German Umlaut "ß". Hence, whenever I now try to type a word with that character, the website instead sends off my email. Do you know of any plugin or other means to disable such shortcuts on certain websites? Thanks!

Answer 1

Use an OS level tool, such as Automator, to toggle the keybindings based on the browser URL:

• A guide to using OS X's Automator to create your own software
• Webkit/Safari/Firefox/API: Can I programmatically read/extract multiple tabs' URLs?
• Is there a way to trigger a Hot Key/Keyboard Shortcut via a Shell Script, a AppleScript or a Automator Workflow?
• MacOS, how to delete unused service item in Keyboard Shortcuts

Answer 2

You can tell Firefox to disable all keyboard shortcuts for websites (as well a couple other options). Look at this pref on the about:config page.

permissions.default.shortcuts (default = 0)

The values can be set as follows:

UNKNOWN: Services.perms.UNKNOWN_ACTION [0]
ALLOW: Services.perms.ALLOW_ACTION [1]
BLOCK: Services.perms.DENY_ACTION [2]
PROMPT: Services.perms.PROMPT_ACTION [3]

Note that there may be some undesirable side effects, eg my fn+delete macOS System function no longer works to delete the next character after my cursor... maybe there's a workaround for that?

More context:

I had a similar problem with Outlook Web App (OWA) in Firefox on Macbook (OSX), where I want to refresh the page with cmd+r but instead OWA would interpret the shortcut as "reply" and pop-up a new window to reply to the selected message instead of simply refreshing the page.
