Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

When I go into fullscreen on firefox macos, hovering near the top shows the traffic lights (fullscreen, minimize, close window buttons) and moves everything down. This may be expected behavior, but it is very annoying as when you try to open new tabs the tab bar moves out of the way of the traffic lights, and the traffic lights area is around the size of the tab bar. Is there any way to make the traffic lights always visible or keep them from moving?

Firefox remebers my data for previously filled in forms - thats fine. BUtr how can I get it to know my basic data (name, email, phone number etc) for forms / sites I havent previously visited?

Hello there!

I have been trying to edit an existing browser extension (for the sole reason of adding new features to it for myself), and I've been trying to add it to my Firefox browser. However, upon trying to install it to the browser, it throws an error saying: "Installation aborted because the add-on appears to be corrupt". I've been trying to read more into this issue all across the internet, but none of the recommendations seem to be working.

I tested my extension locally and with using the about:debugging temporary add-on method, and everything seemed fine.

I tried to re-configurate the 'xpinstall.signatures.required' variable by setting it to false (even thought this method is considered unsafe in most cases), and the issue still occurs

I also tried adding a new gecko ID to it as stated in this article, but to no avail: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/browser_specific_settings

And last, but certainly not least, I tried compressing the extension with web-ext aswell.

My question is - is there a way to add this extension permanently to my browser without submitting it to Mozilla? I did not create this extension, I only added custom integrations to it for myself.

And more importantly - is there a way to add it to the basic Firefox browser, which is not Firefox developer of Firefox nightly? Or maybe create a desktop shortcut that will always start the browser in debug mode, always containing the extension as "temporary"?

I can see that many posts and questions have already been posted regarding this "custom add-on" topic, but my situation is a bit different since my goal is to only use this add-on by myself (and I'm also revisiting this topic since none of the previous suggestions worked in my case)

Any comments, helps, or even links would be greatly appreciated! Have a great day!

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

Im currently reading books (pdfs) in firefox and I would like to hide the scroll bar. Im using full screen mode and especially the bar the the bottom is annoying while reading. I've seen a few topics posted about this issue but they are from a few years back and the solution posted doesn't seem to work anymore. (creating profile/chrome/userChrome.css with some code) But maybe the code is just outdated or I did something wrong. Im not too sure.

The best solution to me would be to just hide the bottom scroll bar. I didnt find any option in about:config except for making them (bottom and right) both thinner.

I would greatly appreciate any help.

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

I used to be able to use the backspace key to go back one URL in a given window. Now, even though I have gone to about:config and changed browser.backspace_action = 0 to 'true', this no longer works, at least not with my new Windows 11 computer. I tried closing and re-opening Mozilla with the new preference, and again with closing, restarting the computer, and then re-opening Mozilla. Please help if you can. Thank you so much.

I have the browser.urlbar.trimURLs switched to TRUE but still as you can see in the screenshot it shows the complete URL with the protocols. I do not want this, I want it to hide it and only show the main link like youtube.com instead of https://youtube.com

Hi so am using version 125.0.1 and on my windows 10 machine I can add custom Search Shortcuts (the Add button is present) but on my windows 11 machine, the same settings page the Add button is dissapeared... Is it a limitation for Windows 11 machines?

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!

Hi. Is there a way to customize the order of Firefox headers and footers on printed pages (including print-to-pdf)?

I prefer the header to be url only, in the center. While the footer has page on left; title in the center, and date on the right.

This used to be easy to accomplish with print options in older versions, then -- as the print dialog changed (and actually improved a lot in most *other* ways) I had to turn to about:config modifications like those described in the 1/27/21 reply here: https://support.mozilla.org/en-US/questions/1323433. But now I can't seem to find any way to have any control over print headers besides "on" and "off."

One problem I find with having both page title and url on top is that these can be long, causing one or both to be truncated.

I'm using Firefox 115.3esr.

I want to disable notifications when a download is finished, however the key in about:config 'browser.download.manager.showAlertOnComplete' does not exist any more. Is there some other way to disable these notifications?

From a security / QOL pov I'd like to disable an extension on some websites, and was wondering if there were any methods to do this?

I searched this question first through reddit and the support site and found similar questions with no updates asked between 4-6 years ago, wondering if there's been a method implemented yet or if it's still not possible.

Thanks!

I have run into an annoyance where I am trying to click on a link in my email to open a new page. Clicking on the link makes a bar show up telling me that Firefox has prevented a popup from being opened (see attached image). I am given the option of managing my preferences / Firefox settings, where I can either go through multiple steps to permanently allow all pop-ups from that website until I restore my original settings, or uncheck a box to permanently allow all pop-ups from all sites until I check that box again. This is annoying because I have no interest in either allowing or disallowing all pop-ups from all websites, or all pop-ups from this specific website, every time I want to open a single pop-up from a specific site. I would rather that the warning bar which tells me that Firefox has blocked a pop-up also display a button allowing me to allow ONLY THIS SPECIFIC POP-UP IN THIS SPECIFIC CASE.

Is this a setting that exists in Firefox? Alternatively, is there a version of Firefox which does have a setting which would allow this? Or is this simply not a functionality that exists for this browser?

Dear Sir or Madam,

I'm running 101.0.1 and spell check no longer works on any mail app like Gmail, Outlook, Yahoo, BT Mail. If I use Chrome or Edge then spell check works correctly. This is despite my Firefox Settings being as below.....

Language Choose the languages used to display menus, messages, and notifications from Firefox. ENGLISH GB Set Alternatives… ENGLISH GB Choose your preferred language for displaying pages. Choose… ENGLISH (United Kingdom) (en-gb) Check your spelling as you type = Tick (Yes)

Could you please advise a fix?

Kind regards,

Neil.

P.S. If I use Chrome or Edge then spell check works correctly.

On my Windows-11 Laptop, the Vertical-Scroll-Bars in Firefox are too narrow for me to use comfortably. I am struggling with the Touch-Pad, Mouse Pointers, causing the frequently needed act of Scrolling to become a dreaded ordeal? If someone would provide clear and concise instruction on how to make the Vertical-Scroll-Bars the Classic Width of old, it would be greatly appreciated. Thank you! lg

On my old iMac, Firefox remembered sites I had visited and filled them in, like if I typed A it would autofill Amazon. This is not happening on my new 2023 iMac and I can't figure out how to turn this on. Also, I could see my site visit history on my old iMac, but this field is blank, with no history of sites visited shown, on my new machine. Help is appreciated. Please keep in mind that I am technically retarded and need step by step guidence. Thank you in advance for your help
