Firefox Community Forum

I use the middle button only for toggling auto-scrolling on and off, or at least that's what I want to do.

That works, unless I mistakenly (often) click the button while over a hyperlinked image or link. In that case, the link opens in a new tab which disrupts my workflow.

How can I set up the mouse in FireFox so that clicking the middle button will ONLY toggle scrolling on and off and never open a link that may happen to be under the cursor?

I've been looking for a solution for this online for ages, and hope there is a setting for this. It's a frustration many times daily.

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 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.

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.

Hi, I unchecked something in my settings and I don't know what I did to cause when I right click to copy something there is no copy and a lot of the rest of the options are no longer there as well. Can you tell me what to do to repair this? It doesn't give me the option to take a screen shot either or I would show you what's left in that popup box. It only give me "Ask an AI chatbot" and the "translate".

Have a nice day, Tom

How do I permanently change the "overflows" attribute of the new sidebar button to false so it doesn't disappear on me when I resize the window and I still need my tabs?

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 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 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 have a Snowflake add-on, which requires WebRTC for connections. But WebRTC is not permanently active in my Firefox browser. See image. I activate WebRTC by toggling the config variable media.peerconnection.enabled into 'true' and the add-on works. For some time, only! After a couple of days it is back to 'WebRTC not detected'. What is wrong?

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 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?

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.
