How to change FireFox switch tab shortcut on OS X?

Question

How can I change the keyboard shortcut to switch between next and previous tabs on Firefox on OS X?

Solution

updated for macOS and current Firefox.

1. default shortcut: Command+Option+⭠ and Command+Option+⭢
2. alternative shortcut: Ctrl+Tab and Ctrl+Shift+Tab
   this shows firefox tab switcher in current version
3. alternative shortcut: Command+{ and Command+}
   this actually requires 3 keys to be pressed on US keyboard Command+Shift+{ and Command+Shift+} and may not work with other keyboard languages
4. alternative shortcut: Ctrl+Page Up and Ctrl+Page Down
5. you can also jump to tabs directly with Cmd+1, Cmd+2, Cmd+3, Cmd+4 etc.
6. you can try a Firefox add-on focused on switching tabs which suits your needs: Add-ons browser
7. just use a BetterTouchTool to remap any keystroke or mouse/trackpad gesture you want to already existing Command+Option+⭠ and Command+Option+⭢ keystrokes.

I personally prefer #7: Command+Option+⭠ and Command+Option+⭢ for switching tabs. I haven't modified Firefox at all and I used BetterTouchTool to remap keystrokes in every other app which uses other commands that these two. Now I can use Cmd+Option+⭠ and Command+Option+⭢ to switch tabs across all apps I use on Mac and it works great.

Please accept the answer, I spent a considerable amount of time searching on Google, before it led me here (I was expecting a stackexchange answer from the start, but it took time until it surfaced).

These work for me. Not sure why it was downvoted. You can also go directly to a tab by pressing cmd plus the number of the tab (ie, press cmd+1 to go straight to the first tab).

Another non-acceptor... Probably abandoned the question... The most annoying thing that happens here... @Downvoter could be... Just my 2¢...

@ChrisHerbert: Although cmd +# is available, it is useless when you have 20 tabs open. You can ergonomically manage as many using e.g. side tabs.

This doesn't seem to answer the question of changing the Switch Tab keyboard shortcuts in macOS.
