Should I use DuckDuckGo Privacy Essentials with Mozilla/Firefox? Would all of the Firefox features work the same or would DuckDuckgo replace Firefox features? If both worked together it would seem to be the best option. I would greatly appreciate some input on this.

I'm using PAC file that returns SOCKS5 proxy, however in my Network Monitor I see actual IP addresses rather than proxified. This is contrary to what Chromium does and it makes no sense. I need to know which requests were successfully proxied.

Is there a ay to enforce it or as usual Firefox is 10 years behind Chrome?

On linux terminal the text should change color but how do I do that on firefox? By the way I have these settings for the caret ui.caretBlinkTime 0 ui.caretWidth 7 Not being able to see the character under the caret is problematic, would be nice if anyone knows what to do.

I Use Mac OS Firefox as my primary client for Gmail, and I always compose emails in a pop-out window. Ever since Firefox 124, these pop-out windows include the tool bar and bookmarks bar, eating up a bunch of space. I do want those bars displayed on my main firefox window, I don't want them displayed on the pop-up Gmail compose windows. Is there anyway to get Firefox revert back to this old behavior?

For introduction, sorry if My English was very bad.

Suppose I was in YouTube (https://youtube.com) domain name, then from that URL, I went to https://youtube.com/history (that is, all in the same domain name YouTube, but different URL) by clicking the history button. The same I did when I clicked https://chat.openai.com/c/d93ac426-c5d1-451b-abc4-fc82739f..... from https://chat.openai.com/c/d93df...... (went from one chat to another) or to https://chat.openai.com/ (went from current to new chat) by clicking the list of chats at leftmost vertical panel. When I saw the top left corner of Firefox browser, the "round circle arrow" reload button was not change to "X" or any other symbol specified that the page was going to different link (different URL). Previously I have had went to this https://github.com/microsoft/playwright/issues/15781 page, and mostly not specified the problems at all. I went to ChatGPT and it said that "I must change the 'false' to 'true' of browser.tabs.remote.separateContentProcess object/variable in about:config. When I searched for that, it seems I found browser.tabs.remote.separatePrivilegedContentProcess" and I have had toggle this to ensure if YouTube, ChatGPT, or other domain will refresh/reload the page when it went to different URL in the same domain, but nothing happens.

The problem is, this is not happen in Chrome Browser. Because of Firefox is my default browser, multi-functional, configurable, I want to make this behavior can also happens in Firefox rather than Chrome. Is there any solution of this?

I’m currently using Windows 10 Firefox v.124.0.1 and am set to auto update. For some time now I’ve been trying to make use of the option to set homepage as a shortcut folder as described: Settings/Home/Homepage and new windows where one of the options is: ‘Choose a Bookmark to be your Home Page. If you choose a folder, the Bookmarks in that folder will be opened in Tabs.’ You then need to delete the existing homepage and select the desired shortcut folder. This works but after it appears to be a static rather than dynamic selection as regardless of any changes made to the indicated folder, the homepage does not change. Am I doing something wrong or expecting too much. Thanks John

Updated to Firefox 124.0.1 on March 28 (from 123.0.1, which was installed on March 12). This update also installed the Keeper password manager addon.

This is a work PC so it's locked down by IT admin, including extensions on FF. I have no access to about:addons ("Blocked Page - Your organisation has blocked access to this page or web site") and it's impossible to install Xpis.

However, extracting info from extension.json shows that Keeper® Password Manager & Digital Vault Version: 16.8.1 was installed at the time the update to FF 124.0.1 happened. See images.

How can this happen? What can be done to remove Keeper, given that I don't have access to about:addons?

Possibly relevant: I do have some extensions that I had installed before Firefox extension access and install was locked down by Admin (lock down of FF was done remotely through some kind of policy), including LastPass.

As I am a corporate website administrator and I use an ultra-wide monitor with a resolution of 3840x1600 pixels, I need to be able to run firefox with window size of full HD to verify the compatibility of the site for common displays.

How can I ensure that the Firefox window always starts at this size?

In the case of Chrome, you just add the parameter -window-size=1920,1080

Unfortunately, this solution does not work here (so it worked in older versions).

I found some plugins that promised this, but none worked correctly.

I find the option to set a default size to be very basic and essential and prevents me from switching from Chrome to Firefox.

i made a custom firefox colour setup for my desktop machine, and it doesn't have any option to save it- because of this, on my laptop which is synchronized to my desktop's firefox settings, it is not showing up at all and if i go to firefox colour it isn't there for me to add. so how do i DO this???

i do not want to maker my custom setup public so it is not available to all, it is my own setup using some of my own artwork which i do NOT want made public on the internet.

there MUST be a way to save it however and let my laptop's firefox also display it,m yes???

and on that topic, why isn't it just automatically synchronizing when everything else does?

Hello, I use Firefox as my only browser and I use the shortcuts because they're really helpful. But every time that I lunch Firefox all the pages in the shortcuts "call" their websites, I see it from pihole and all the requests are made every first lunch of Firefox. Probably it's something related to the cache and to give better perfomances in case I wanna select one of those shortcuts, but I don't want that all of them make a "call" to their respective websites. I think it's something related to privacy and freedom about what I want to do with mt browser. Is there an option to block those connections? In case there isn't an option is possible to implement it? Thank you so much

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Firefox correctly redraws the addon window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
5. Reopen the addon window
6. Switch system theme globally again
7. Observe that Firefox does not correctly redraw the addon window
8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
9. Reopen the addon window
10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

System details:

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Desktop environment: GNOME

When I open Firefox, the tabs from the previous session do not open despite the setting. I end up with a start page showing only a new tab page. This has been happening over the past few days and I don't know why.

Does anyone have any ideas why this is happening.

I'm installing a Docker service set onto a new Ubuntu system, that has Firefox installed by default. One of the services is a GUI application.

However, when opening Firefox for the first time, a dialog shows up that I would like to disable (attached).

How can I disable this?

I'm running Firefox using: "/usr/bin/firefox --kiosk http://localhost"

I've already followed a lot of the suggestions in here: https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs (and verified they are indeed set after installing my own "user.js" file), but I cannot find an about:config preference that disables what I'm still seeing.

Any help or ideas?

In the browser settings I use a color preference that replaces white with black, this works with pages where Dark Reader is not available. These settings are needed so that when surfing the web at night with the dark mode on, my eyes don't hurt from contrasting bright white elements with dark-colored pages. For example, it works on single image pages - in situations where except for the image the rest of the page is colored solid white; It also works for some add-ons - on settings pages and pop-ups.

I'm interested in being able to automate toggling on/off the «Use system colors» checkbox, which is in the browser «Color» settings. It would be great to somehow synchronize the activation of night mode in Dark Reader with disabling checkbox responsible for using system colors. Or, for example, make it so that when the «Website appearance» setting is set to «Automatic», the checkbox is switched accordingly together with it - being disabled when the appearance is dark and enabled when it is light.

Hello, Under about:preferences I went to applications. Under mailto there were references to Yahoo and Gmail which I deleted. Now then when I click on an email address link on a webpage the mailto menu pops up like it always has but Yahoo and Gmail are no longer listed as email options. How do I get those links back? Firefox is listed as the default option but because there are no links to webmail services there is no way to send an email from that menu. Sincerely, MKH
