AltGr (the right alt key) essentially translates to ctrl+alt on Windows and some Linux configurations. It also acts as a compose key on some configurations, making it quite unreliable for navigation as the system IME may intercept the key before sending it through.

You can rebind it back to a normal alt key at the operating system level if you don't care about the AltGr functionality, that'll probably fix a whole bunch of unexpected problems you may be having in other programs. I think Firefox altering the ctrl+alt+left/right behaviour would break more workflows than it fixes, to be honest.

What's it likely to break? I don't have anything bound to that combo by default.

I forgot what exactly broke, but I do remember assigning something to my ctrl+alt+left/right keys and finding out that various applications (and I think maybe the rich text edit field?) got very confused.
