Why is there in about:config no reference to documentation of the displayed settings?

e.g. browser.chrome.toolbar_tips.hide_on_keydown

What is it? What is the meaning of the values? What is the default value? Why do we have to guess?

It is probably documented somewhere (I hope). Why is there no reference to it in about:config?

Firefox downloads .ai files too often as .pdf files, which, although I can open in Adobe Illustrator and/or change the file suffix to open in Adobve Illustrator instead of it automatically opening in Acrobat (unless I right click into Illustrator), is a hassle and concerns me of unintentional file corruption. I don't know why Firefox is downloading .ai files as .pdf files, but it is impractical and frustrating. None of the file download settings I adjusted fixed the issue.

Is this a known issue? The only thread/question I found on this type of issue where files get downloaded as the wrong filetype/suffix was an archived question on .ddd files being downloaded as .pdf files. Please let me know if this is something the devs are aware of and can work to fix it.

It certainly appears they have, with the left and right padding growing wider. In fact, they both look about twice the size of the top and bottom padding, whereas before I remember them as being about equal. The change was immediately apparent with my home page!

Any particular reason for this?

Dear Mozilla Support Team,

I am working on configuring Microsoft Intune for organization and need to manage specific settings for Firefox via Custom CSP policies. However, I could not locate the necessary OMA-URI details for the following Firefox settings:

Advanced Options: Check my spelling as I type Advanced Options: Preference State Advanced Options: Use AutoScroll Advanced Options: Use Smooth Scrolling Disable XPI Installs These settings are crucial for maintaining compliance and ensuring a smooth user experience within our managed environments. Could you please provide:

1. The exact OMA-URI paths or equivalent policies for these settings? 2. Additional documentation or resources related to Firefox Enterprise policies for Intune?

I have a Linux PC where, when I right-click, I see shortcut letters in the context menu (the one that appears when you right-click). So, if I want to inspect an element, I right-click on it and press Q, and the inspector opens right away. This saves me time from navigating through the menu. However, on my other MacOS PC with Firefox, it doesn't do the same. I've searched for solutions but haven't found any.

There are times where I like having the title bar appear on my laptop display of a webpage. Other times I want to take a screenshot of selected page content, and the title bar just obstructs ability to fit the bottom line or two of the page content I want to screenshot. Yes i know I can reduce the zoom size of the page display itself, but sometimes (often) due to the page layout's CSS, this results in both too-small type for me to comfortably read AND even with the text reflow, it's not enough to reveal the extra bottom of page content I am trying to capture.

The Firefox UI controls are very robust and well-appreciated how much customization can be had, but still, the number of steps required to go in and turn Title Bar off is just way too many for quick and efficient workflow -- especially when after getting the screenshot I want, I will want to just turn Title-Bar back on. Surely there must be a way to create an icon option that lives next to Home, Bookmarks, Downloads, Refresh whose function is to actuate a quick 1/2 second toggle off, then a quick toggle back on?

Sat. 04/19/2025 @9:10 am CDT - Hi. About 2 months ago on any Settings page, FF began to show "your browser is being managed by your organization." The problem is - it's a STANDALONE box, not connected to any network beyond my ISP. I do own websites but I'm not perpetually logged into the host company, so their switch to Microsoft Entra wouldn't have an effect, I would think.

What settings do I change to make FF know that I'm not on a network? Thanks in advance.

Dear Mozilla Firefox Team,

My name is Bohdan, and I am an active user of your browser. I greatly appreciate the efforts of your team in developing such a convenient and secure product. I would like to express my gratitude for the excellent work on Firefox and would like to propose a few ideas that I believe could enhance the user experience.

Selective Tab Removal Feature Often, when working with a large number of tabs, there's a need to close only some of them. It would be very useful if there were a feature that allows users to select multiple tabs and close them simultaneously. This would significantly simplify the organization of work with tabs and allow users to manage open pages more effectively.

Adding Ukrainian Language to the Page Translation Tool For Ukrainian users, it is important to have the ability to translate web pages into Ukrainian directly in the browser. Given the significant number of Ukrainian-speaking users, this would be a very important and helpful addition. I hope that such an option will be implemented in future updates.

I would be very grateful if you could consider these suggestions for inclusion in future updates. I believe these changes would be useful for many users and would enhance their experience with Firefox.

Sincerely, Bohdan
