Please add a Custom wallpaper options, Your browser has been the best so far i have used many browsers but i would love to have a custom wallpaper option and live wallpaper option too if possible just like operaGX has. Anyone can upload a wallpaper there.

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.

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 just purchased a year subscription for the Mozilla VPN. I want to be able to verify that the FireFox browser I'm using is accessing the web via the VPN. How do I verify that? I don't see any icon indicated that it's a VPN connection.

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?

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'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.

My Policies.Json can only block 1000 websites. Nothing after the 1000th entry is blocked. Is there a way to remove this limit?

Firefox 150 on Windows

Thank you

In the year 2024, firefox still does not allow a simple way to set any URL you would like as the new tab url (without an extension).

Users were previously able to use extensions like NewTab override to have a relatively seamless experience changing their new tab page. However after certain changes, these said extensions can no longer set your new tab page to a local file, and can also no longer clear and focus the address bar.

I am simply requesting a feature within firefox to set a custom new tab page, without having to create any external configs, or without using any extensions. This basic feature has been available in chromium browsers for years, and firefox already includes a feature just like this for the "Homepage and new windows" setting, where it allows you to input a custom URL to a local file or site to put it as your homepage. However, this same setting for some odd reason does not exist for the "new tabs" option. Why is this?

As of now, I've had to use a manual override along the lines of this:

``` // shenanigans for setting a different new tab page const { classes: Cc, interfaces: Ci, utils: Cu } = Components; const { AboutNewTab } = Cu.import("resource:///modules/AboutNewTab.jsm", {}); // path to new tab can be a url or file const newTabURL = "file:///home/faaris/.local/packages/startpage/fazzi/index.html"; // set the new tab URL AboutNewTab.newTabURL = newTabURL; ```

this should not be needed. Having to modify files in system protected folders should not be needed for such a simple option.

I was planning to start using the AI chatbot sidebar finally, tried out all of the free options available and settled on HuggingChat. The very next day, HuggingChat ceased operations. I don't really like the other preset options, but I have a couple of other models that I would be interested in trying out. Is there some way to add a different model than the five preset or am I just out of luck?

I am interested in Firefox View, but I do not see that button on my toolbar (see attached image). When I search extensions I don't see that come up as an option. How do I add Firefox View?

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?

I opened Firefox today to find that nothing would show up, at first I tried clicking on the icon on the taskbar, but it just made the icon bounce with the window briefly popping into view. That's when I realized that Firefox was completely offscreen and unusable.

For context, last night, I had 3 windows open, two were regular sessions, the last one was a private session I had open on a temporary second monitor that I unplugged afterward. My dad lended it to me, so I'd rather not ask him again unless I absolutely have to. I closed them in order making sure to close the default window last thinking that Firefox would open there next time I launch it, but comes tomorrow and when I launch Firefox it opens off-screen and I can't interact with the window at all.

There also seems to be no way to bring it back directly to my screen on this garbage OS everyone calls "windows 11" according to their help forum: https://learn.microsoft.com/en-us/answers/questions/4139775/app-runs-off-screen-in-windows-11?page=2#answers

So, I'm commenting here via brave browser, first to report a bug because I don't think Firefox should remember the last position of a private window of all things, but also because I don't know where else to go to ask that question since windows 11 itself cannot seem to have an option to solve this problem either. I know the position is stored in the profile folder, so what should I edit in there to get Firefox back where it should be? No, I will not delete/reset it it has a ton of search engines and settings that Firefox won't sync.

Hello,

I wanted to ask if there’s a way to configure the setting for "Store data in permanent storage" (or "Daten im dauerhaften Speicher speichern" in German) to always block/disable ALWAYS via Group Policy or Registry Editor.

As we are a small company, I would like to apply this setting for all Active Directory users.

Thank you

Best regards,

Andreas

I am seriously concerned about the upcoming use of AI in Mozilla Firefox. The only reason I use Firefox is because it is one of the few remaining widely compatible browsers that allow me to switch off any AI features. Generative AI is needlessly wasteful and absolutely pointless. Is there any way to prevent this from being forcibly added to Firefox?

I noticed recently, that you cannot copy and paste with the right click mouse buttons and seems to want me to use the Cntrl C and Cntrl V. Is there some way to re enable that on the mouse? It works in every other application except firefox, and I would prefer to use the mouse, as I am the most comfortable with that.
