Firefox Community Forum

zen_browser has this feature which I use multiple times per day every day: keyboard shortcut ´shift+cmd+c`to copy current URL to clipboard.

This is such a useful feature. It helps me save time and speed up my workflows a lot, so much that it's absence in Firefox is preventing me from going back to Firefox.

The feature was implemented in v1.6b back in early 2025 in zen_browser.

This might be quite "old man yells at cloud" of me, but oh my god I am so fed up of everything putting AI in as a "feature" for no reason.

1) No one asked for this. 2) It is bad at doing whatever it is designed to do. (It's not helpful, it's not even neutrally unhelpful, it's ANTI-HELPFUL.) 3) It is always on by default, or worse, impossible to turn off.

At the very least AI features need to be off by default, because it's rubbish.

Firefox is meant to be a bastion of sanity and safety in a world of exploitative techbros trying to steal our data and trick us into making money for them. So-called "AI" goes against this. Please, Firefox, be better.

As of 20th Nov 2025, here's how to turn off AI features. Go into about:config and set all of these to false (yes, you’ll have to copy and paste them one by one):

• browser.ml.enable
• browser.ml.chat.enabled
• browser.ml.chat.menu
• browser.ml.chat.page
• browser.ml.chat.page.footerBadge
• browser.ml.chat.page.menuBadge
• browser.ml.linkPreview.enabled
• browser.ml.pageAssist.enabled
• browser.tabs.groups.smart.enabled
• browser.tabs.groups.smart.userEnabled
• extensions.ml.enabled
• browser.search.visualSearch.featureGate

in addition to nuking AI, it’ll also speed up your browsing

These are technically two separate issues, but both pertain to functionality of the mouse and keyboard. Whenever I right click to bring up the menu, the options (despite being functional) do not appear in the menu proper. Instead there are just empty buttons. In addition, certain hotkeys aren't working at all. Ctrl+C and Ctrl+V to copy paste are doing fine, but Ctrl-T and Ctrl-W to open and close tabs respectively do nothing. Neither of these issues were happening yesterday.

The keyboard shortcut to take screenshots [Ctrl + Shift + S] used to work a few weeks ago but it has stopped working for quite a while now. Doesn't work on any site, I can only create screenshots by right clicking and pressing the button manually.

started a new profile, imported bookmarks, the about:config settings won't die. I've deleted the user and prefs.js data etc. but all the dumb changes I made before switching users just make their way back no matter how many new profiles I create. I have standard Firefox, with Nightly and Private versions installed. Win 11 25H2 whatever its called now.. please help.

Hi all,

I’ve been experimenting with Firefox’s new AI chat integration and adding custom prompts via `about:config` using `browser.ml.chat.prompts.#`.

Right now, prompt values are static JSON strings, like:

```json {"label":"Answer","id":"answer","value":"Answer selected question"} ```

This works great for fixed text, but there’s no way to dynamically include useful context like the **current page URL**.

For example, I’d like to create a prompt like:

```json {"label":"Summarize w/ URL","id":"summarize_with_url","value":"Summarize this selection. Page URL: {{url}}"} ```

…but currently, `{{url}}` (or similar placeholders) isn’t supported, and the AI chat doesn’t automatically pull the page URL as context.

This means I either have to manually copy/paste the URL or use a separate bookmarklet workaround, which breaks the smooth workflow.

• • Feature request:**

• Add support for variables like `{{url}}`, `{{title}}`, or `{{selection}}` in `browser.ml.chat.prompts`.
• This would make prompts far more powerful and let AI chat automatically reference page context.

Has anyone found a hidden about:config trick for this, or can this be added to Firefox’s roadmap?

Thanks!

I often use the key combination Ctrl+Alt+X in Google Docs when on different devices but it doesn't function properly when instead it brings up the AI sidebar gadget. Removing the sidebar button doesn't really help and it's annoying. So how exactly do I turn off the key combination for the sidebar?

Hi I see that Firefox has the option to ask an AI chatbot, with your options for AI being Claude, GPT, Gemini, and Le Chat Mistral. What I'm not seeing is an option for Lumo, Protons new chatbot. My question is is there any future support coming for Lumo, or better yet, an option to let FF users choose ANY chatbot, not just these 4?

Hello,

I wanted to customize my Firefox new tab with a local HTML file, such as "/path/to/my/index.html". It was possible to use this workaround: https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main https://github.com/Jangsoodlor/Firefox-New-Tab-Config/tree/main

Which implied a configuration file (sometimes named "autoconfig.cfg", "firefox.cfg", "local-settings.cfg" depending on the guide since the name is arbitrary) with javascript code. In the new Firefox 136, this code fails to execute due to a new API being used.

If you want to customize your new tab, follow the previous guide, but on the configuration file write this code instead:

// My new tab
try {
  const ff = {};
  ChromeUtils.defineESModuleGetters(ff, {AboutNewTab: "resource:///modules/AboutNewTab.sys.mjs"});
  ff.AboutNewTab.newTabURL = 'file:///path/to/my/index.html';
} catch (e) {ChromeUtils.reportError(e);}

Note that the file must start with a comment

Adapting the "/path/to/my/index.html" to your needs.

Thanks to @mkaply (github) on this thread https://github.com/mozilla/policy-templates/discussions/1190 for the new API method.

I post this here in case someone has the same issue, because is quite recent and hard to find on the internet.

I am uncomfortable with the push for unnecessary ai content and features on firefox and if they are added without easy ways to remove or disable I will be switching to a different browser

I'm a user of the new "Ask AI" feature in Firefox, and while I appreciate the convenience of having an AI assistant in the browser, I've noticed a significant limitation that prevents the feature from being truly useful.

The Problem

Currently, when you right-click and select the "Ask AI" option, the prompt sent to the chatbot only includes the selected text and the page title. It completely omits the page's URL. This is the prompt that is sent:

* * I’m on page “<tabTitle>Get Support | Mozilla Support</tabTitle>” with “<selection></selection>” selected.

• * Please summarize the selection using precise and concise language. Use headers and bulleted lists in the summary, to make it scannable. Maintain the meaning and factual accuracy.

This is a major issue because without the URL, the AI cannot access the full context of the page. It can't scrape the content, analyze the structure, or understand the full context of the selected text, which is often crucial for generating accurate and comprehensive summaries or answers. The feature, as it is, relies entirely on the user manually selecting a large block of text, which is clunky and often insufficient.

Proposed Improvements

   Include the URL in the Prompt: The most critical improvement would be to automatically include the page's URL in the prompt sent to the AI. This would allow the AI to properly "see" and interact with the full page, making tasks like "Summarize" much more effective.

   Allow Custom Prompt Editing: A second, highly beneficial feature would be the ability for users to customize the prompt before it's sent. This would give users more control over the AI's output and enable more creative and specific uses of the feature beyond the pre-set options. This would also allow users to manually insert the URL if needed, as a workaround for the current limitation.

These changes would transform the "Ask AI" feature from a novelty that only works on selected text to a genuinely powerful tool for research, content analysis, and productivity.

Thank you for considering this request.

Hi All

I am trying to set up a background image to my FFX home page. In other browsers that is simple; I see no simple way in FFX. Is this a failing? Can it be overcome, simply?

I am unable to locate the setting Enable Link preview. I am using Firefox 142.0 on Windows 10 Home 22H2. This setting does not appear under Settings>General>Browsing. Are there other settings that are required to enable this facility?

hi, spellchecking works fine when using Firefox in Linux, but not in Windows 11. For instance, I can enter comments and replies to magazine articles while using Linux and they're spellchecked as I go by highlighting misspelled words etc, but if I'm in Windows 11 and on the same comments section, although my Firefox settings are the same the spellcheck doesn't happen. Can anyone please tell me what's up with that?

New installation of Debian 13, Firefox setup with sync on successful. However, I wanted to add hone button and a few other mods to the toolbar but when I started customize the toolbar from menu pic the customization page would not work, it appeared and seemed OK but when I dragged and dropped anything it would not work. I could pickup items but they would not place in toolbar and just snapped back to the pallet. I tried several different ways to enter the customization area but it was always non-functional.
