I've noticed that whenever I press ⌥⇧Space (option-shift-spacebar) in Firefox Developer Edition, it causes the page to refresh.

This behaviour seems to be consistent across devices.

Is there a way to change/disable this behaviour? It is very inconvenient, as it often causes me to accidentally trigger a page refresh when I type an em dash (`—`) in a text input (opt-shift-dash, and then type a space character after it, I'm very likely to hit opt-shift-space by mistake 🙈).

I love FF and I appreciate the intentions behind the new update for quick/custom search engines in Firefox 140, but I can't help but notice that the new UI for custom search engines requires the user to manually click on various buttons and does not allow one to navigate the process via keyboard only. (Unless I'm missing something?) Prior to this UI update, I was able to fully navigate the drop-down and select my custom search engine of choice using only my arrow keys and enter key. Now, the "search with XYZ" button that pops up if you type the site name is only selectable if you click on it, and cannot be highlighted with the arrow keys.

I am not personally disabled in a way that prevents me from using my trackpad, but having to stop what I'm typing and go out of my way to click on various UI elements is a real stymie in terms of flow, ease of use, and efficiency. At least for me.

Is there some kind of secret key combo I can use? Or an about:config setting to enable keyboard navigation in custom searches? Is it a bug? Or simply the removal of a feature?

I hope I will be able to use my arrow keys to select my search engine again in the future— Thanks

Please 🙏 I am tired of the same thing nothing changes I will get control over my podcast and Cash app pay pal and they take it right back I truly know who's doing this where do I start

F12 is near the backspace key on my asus laptop and I keep accidently hitting it and would like to remove this fuctionality. I can just use ctrl shift c if I need it

My sanity is at stake here!

When I installed Firefox, I struggled to find a theme that was easy for me to see. So many had dark borders/backgrounds or busy backgrounds or transparent. It appears that I'm using the default at present and am happy with everything but the visibility of those little icons. Is there is a way to make them darker? Thanks

I'm trying to add the Dashlane extension to my laptop running Windows 10 or 11, and Firefox. But I cannot do this as my computer is in safe mode (troubleshoot mode?) How do I get out of this mode so I can add Dashlane extension. Thanks for your help;. Jonnie

Firefox has been working fine, but today when I clicked to start, I received an error message. "The file or directory is corrupted or unreadable." When trying to uninstall Firefox, Windows cannot find the uninstall helper. When I try to download a new version, I receive an error message: "Couldn't download - virus scan failed." Windows Security reports are all good. A scan found no viruses. Firefox will not open at all.

Note: This is also an accessibility issue as those of us with limited or impaired motor control can be inordinately affected in a way that limits our use of Firefox or makes it virtually impossible to use in any use-case more complex than browsing YouTube.

Issue: There are certain, pre-defined, keyboard shortcuts within Firefox whose action is both immediate and irrevocable. Those of us who have limited, or impaired, motor control are particularly susceptible to this, though I have heard anecdotal evidence that other - unimpaired - users suffer from this as well.

Example: There is a particular key combination that I periodically, (accidentally), hit while typing that immediately and irrevocably clears the dialog that I am entering text into - as I am doing here - with no possibility of recovery and no warning that a potentially disastrous action is about to take place.

My specific case, (that is, the most recent instance of my specific case), occurred last night while composing a reply to a topic within the Microsoft Flight Simulator forum addressing a particular, and popular, issue with the sim.

I spent a significant amount of time creating this message - setting paragraph formatting, creating tables, inserting images, carefully crafting the text and such like, that had taken me upwards of an hour to prepare.

While typing - I managed to inadvertently hit a magical "Nuke-and-Destroy" key combination that caused all my lengthy, careful, painstakingly crafted work to immediately vanish with no chance of recovery.

To this very day I still have no idea what combination of keys does this - and if I knew, I would try to suppress it at the keyboard/system level so that Firefox never sees it.

When I searched for a solution to this problem, I found the following article on this site: [https://support.mozilla.org/en-US/que.../1364260]

In essence, (though it was worded much more politely), the answer was that Mozilla knows about the issue of potentially undesirable "magic" key combinations, has no plans to address it, and if you don't like it it just vacuums being you.

Though this particular key combination might be useful in certain cases, (though I cannot imagine what use-case would benefit from accidentally destroying hours of work), the utterly irrevocable nature of the action - and the absolute lack of any warning whatsoever - makes this a classic case in the annals of horrid user interface design; to the point of being a functional bug even though it works as designed.

A more desirable action would be to:

1. Allow it to be disabled entirely, along with the other potentially annoying/disastrous keyboard shortcuts.
2. Provide a (default) action that warns the user that this action is both immediate and irrevocable and allowing the (default) option to abort the action. Extra credit: Allow the user to permanently disable the offending feature from the dialog.
3. In the unlikely event that a particular user might wish to use this regularly and deliberately, allow the user to bypass the warnings and permanently enable the feature - with the caveat that it vacuums being them if they do something wrong - not unlike the disclaimer when accessing about:config.

I would suggest that this action, and the action of other "magic" keys/key-combinations within Firefox represents a significant burden to those of us who may already be struggling to use a keyboard. Perpetuating this class of issue, especially since it's a known issue and there's no desire whatsoever to accommodate those of us negatively affected by it, borders on both arrogance and ableism.

I would like to humbly place this request at the feet of whomever is responsible for this atrocious policy and earnestly request they reverse this unpleasant and destructive behavior.

Respectfully submitted: Jim Harris.

Я пытаюсь использовать сочетание клавиш ctrl+shift+c, что бы скопировать текст, но, вместо этого открывается devtools, я не могу использовать другое соччетание, пробовал отключить это в настройках devtools, но это не сработало, так же пытался выключить devtools, но не помогло

When a tab is opened or moved into a new window (image 2.png), the additional windows will disappear from the Windows taskbar after a few moments (image 3.png) and cannot be accessed via Alt+Tab, the only way to reach that window is via dragging the windows around or with the Firefox View tab.

Can we get a setting that disable the Quick Find feature or at least its keyboard shortcut.

It breaks keyboard shortcuts on multiple sites, as it is often used to select the search bar(Youtube, Github, ...)

I just setup this firefox extension to help me manage my 800+ tabs - https://addons.mozilla.org/en-US/firefox/addon/simple-tab-groups/ . This might have even been causing Firefox to crash and my computer to restart, but I'll save that for a separate issue. The extension has some suggested shortcut keys, particularly Ctrl + Backtick and Ctrl + Shift + Backtick to switch between next and previous Tab groups. I tried to go to Manage Extension Shortcuts in settings, and tried to specify the keys Ctr + Backtick, but the input box would not accept the key. In fact it only seems to accept Ctrl + <alpha-numeric> key. or Ctrl + Alt + <alphanum>

Is there anyway to enable this? Most keys like Ctrl + alphabets appears to be already mapped by firefox's default mappings. my Ctrl + numbers are also similarly mapped by another tab extension to switch tabs.

Thanks, arun

The keyboard shortcut L of "copy link" in right menu over a link is inconvenient for most right-handed people. I want it back to old keyboard shortcut A.

After new version 134 update, the shortcut L to A is not working again.

I posted 2 links in 2023 and 2021, but they are not working now. https://support.mozilla.org/en-US/questions/1333526 https://support.mozilla.org/en-US/questions/1433785

Could you please fix this bug?

Thank you so much! Brian

I have 2 instances of Firefox: I use stable for all my professional work, and I use Developer Edition (Aurora Channel) for personal things. The stable branch works fine. In Aurora though, certain key combos will not work. This even persists in troubleshooting (safe) mode.

Specifically, it seems anything using both ctrl+alt will not register alt, only ctrl. alt, alt+shift, and ctrl+shift all seem to work fine, but ctrl+alt and ctrl+alt+shift do not. Again, this works fine in stable, so I am clueless as to why it doesn't work in my other instance.

Another detail is that this happens on multiple websites, not just one. The post prominent one is Google Sheets. In sheets, you can insert the date using `ctrl+;`, the time using `ctrl+shift+;`, and both using `ctrl+alt+shift+;`. Inserting them separately works fine, but both causes only one to insert.

With normal mice, when you scroll you typically scoll in steps which you feel as the mouse wheel feedback.

The issue here is with high resolution scroll wheels, whether that is a knob or a "frictionless" mouse wheel like on higher end logitech mice.

What happens: You slowly rotate the scroll wheel while nothing is happens in firefox, then you get to a certain point and firefox scolls one step, then you continue to slowly rotate the wheel, and eventually firefox scrolls another step.

What should happen: It continuously scolls as you rotate the wheel. This works in chromium browsers and other chromium based apps like discord, steam, etc, it also works in kde settings app, dolphin, okular, etc. But not firefox. It even works in terminal.

Both firefox and thunderbird are like this.

Is there a way to get this working or is it simply not supported in firefox? If so then feature request: get high res scoll wheels to work

When I press a hotkey that involves Ctrl (ie. opening a new Tab via Ctrl+T or closing one via Ctrl+W) Ctrl sometimes remains stuck until I press it again. This will cause issues ie. when I open a new tab and try to type a new address (or search term), and Ctrl causes new hotkeys to be executed.

I've even tried launching firefox with a new profile, and on safe mode (firefox --safe-mode -p <something-else-than-usual>), so no bookmarks, cookies or extensions should be causing this, and it will still happen sometimes. The annoying part is that this seems to be an issue with performance. It happens less-often with the empty profile and safe mode, but it still happens, especially if I had just opened a new page some tab, causing the most minute thing for firefox to process.

The problem is probably not the computer specs either (below my specs). Indeed, from what I can tell, firefox does not even seem to function particularily slow in any case. Just this ctrl being stuck seems to happen.

I have also tried disabling hardware-acceleration (and explicitly enabling it), no effect.

Other interesting facts I've discovered: - This for sure does not happen in other programs and - This does not happen with the Ctrl for all the keybinds within firefox. For example, Ctrl+A (for select all) does not trigger this

I'm not sure what else I could share at this point

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.

This does not work anymore and I get an edit drop down with copy, paste etc It works on Chrome and Safari. I checked the config for "browser.fixup.alternate.suffix" and it is set to .com.

I'm currently using FF 134.0.2 on a Mac running Sonoma 14.6.1. I'm unable to use the Find shortcut (⌘ + f), but I am able to use other shortcuts in Sheets: ⌘ + c, ⌘ + v, ⌘ + Option + m. That shortcut operates as expected on other sites, opening the Find pop-up at the bottom of the browser. It's not working within Sheets to search a spreadsheet or at the browser-level when on a Sheets tab.

Any idea why that one shortcut isn't working?
