User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:126.0) Gecko/20100101 Firefox/126.0
Steps to reproduce:
Edit text in a textarea on macOS. Make a mistake while writing. Then try to highlight part of the sentence I want to edit using the macOS native keyboard shortcut, "shift+opt+left" and "shift+opt+right".
Actual results:
My browser navigated to the previous tab, which takes me away from the textarea I am editing and to an entirely different website.
Expected results:
The words I wanted to highlight should have been highlighted so I could edit them, or put them into the clipboard.

Is this keyboard override seems like a recent change in behavior?

I'm going to test with a different profile, or in safe mode to see if anything else is going on.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

I ran Firefox in Troubleshooting Mode and could not reproduce. Going to try to disable extensions to try and figure out which one might be causing this issue.
Score a win for Troubleshooting Mode.

I found the culprit. The "Tree Style Tab" extension. From their Release Notes:
4.0.16 (2024.6.9):
- Add new keyboard shortcut slots "Simulate Up/Down/Left/Right Key on Tree" and assign default shortcuts Alt-Shift-Up/Down/Left/Right. They provide both spatial focus move on faviconized tabs and collapse/expand tree like arrow keys on tree items.
I'll admit to being a little confused since I didn't think extensions could override Firefox or system shortcuts like that?
Something that might be useful to me, as a user, would be to have some way to view, "what extensions have updated recently?". Similar to what mobile OS vendors provide. That might help me narrow in on which extension(s) to focus on when troubleshooting a situation like this. Just a suggestion, while I am thinking of it.
Regardless, I will file a bug on the extension and see what happens.
My apologies for the noise.

If anyone else stumbles across this bug, the developers of Tree Style Tab are aware of this issue, and will issue a new version which does not conflict with macOS native keyboard shortcuts.
