Beyond the default Firefox browser hot keys anything other then that is either addon or 3rd party apps to make those changes.

For Mac, the article still lists Control + Return:

So it should work. However, there is a setting to disable it. Could you check:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(2) In the search box in the page, type or paste ctrlCan and pause while the list is filtered. Firefox should show one match (please ignore the line with Boolean Number String).

(3) If the browser.urlbar.ctrlCanonizesURLs preference has a value of false, double-click it (or click the Toggle button or Reset button at the right end of the row) to restore the default value of true

• If you changed that, any improvement?
• If the false comes back after your next Firefox restart, we need to help you hunt down the culprit, possible a user.js file.
• If it shows a lock icon at the left and cannot be changed, we need to help you hunt down an Autoconfig file or possibly an Enterprise Policy.

Hi, I had checked browser.fixup.alternate.suffix already but rechecked and it is set to true. I changed it to false and back to True but I still do not get .com appended. I am on 136.0b7 (aarch64)

What about browser.urlbar.ctrlCanonizesURLs ?

also set to true

Jscher you were thinking correctly on this. But it appears the latest MacOS Sequioa release has stolen the Ctrl+Enter shortcut for itself to open context menus so Firefox can't use it. I tracked it down to this bug: Bug 1945422 - Ctrl+Enter keyboard shortcut in the address bar no longer adds "www." and ".com" to the address bar string on macOS

The shortcut to add .com to urls has now changed to: Cmd+Enter

The patch with the new keyboard shortcut, Cmd+Enter, has not been added to Beta yet but it looks like it will very soon. The developers also plan to update the old shortcut to the new one in the KB article you found Jscher.

Notes from the bug: MacOS Sequoia introduced a new default shortcut to open a context menu: Ctrl+Enter. This conflicts with address bar shortcut to complete search string (e.g. "example") to .com URLs. We are changing the shortcut on MacOS to Cmd+Enter. The existing pref browser.urlbar.ctrlCanonizesURLs is named after ctrl, though we think it's not worth changing it, as that would break existing resources pointing to it, and it's quite common on the Mac to replace ctrl with cmd in general.

[Suggested wording]: Due to recent changes in MacOS Sequoia, the shortcut to complete search strings to .com addresses has been changed on MacOS from Ctrl+Enter to Cmd+Enter. The preference to disable this feature, browser.urlbar.ctrlCanonizesURLs, was not renamed, and it's valid across all the supported platforms.

Hello, before Firefox 136, I had used Cmd + Enter to open the result of the address bar in a new tab. This update resulted in unexpected behavior for me, though I understand why the change was justified in general. Is there a setting to change the behavior back to how it was, for my browser?

Update -- I was able to change this to the old Cmd + Enter behavior by going to about:config and setting browser.urlbar.ctrlCanonizesURLs to False. I wonder if this setting would be a good candidate to be exposed to users in the Preferences page? This behavior mimics that of Chrome, so it feels intuitive to me, and I'd guess that it might to some other users as well.

Fixed in last release but cmd enter instead of cntrl.

This change really messed with my muscle memory, I frequently use Cmd+Enter to open a URL or search query in a new tab which IMO is a much more useful and common binding. Cmd+Enter in every other browser (Safari, Chrome, Edge, Brave) will open whatever you type in the address bar in a new tab, as well as Alt+Enter in Windows/Linux (same thumb position). However, only Firefox on macOS will autocomplete with www.*.com (too bad, all the web pages that don't use www or .com) making it inconsistent with every other browser and even Firefox on other OS.

I'm going to have to switch to Brave until there's a way to map Cmd+Enter back to opening in new tab as I use multiple browsers regularly and I can't bother to remember to move my thumb leftwards to Opt+Enter instead. I end up hitting Cmd+Enter dozens of times per day.
