For years, I've been looking for a way to disable the space bar from acting as a page down button, including trying out scripts to solve it, but please let users disable that shortcut in the about:config page.

It is difficult for me, since I see that ability to change what the backspace does is available, but there's no option for the space bar. The space bar is something that I often accidentally hit, and it would be of immense relief to me to no longer have that issue of it paging down what I reading. This is my request, and there are others who also feel similarly.

Looks like [removed] garbage, stupid [removed] decision to make. I want them gone you ignorant [removed].

When I right click a tab and select Bookmark Tab, the "Location" is preselected from one of my existing bookmark folders/locations. I thought it might adapt to the most recent or most often selected folder; however, it seems to present the same "default" location every time I bookmark a tab - a folder I have not barely used in months. I realize I can select another folder, but it is annoying for it to select the LEAST used and my personal least favorite folder EVERY TIME, for MONTHS.

1) Is there a way to select which folder it preloads to save bookmarks to? 2) Why is it selecting THAT folder? 3) If there is no way to set a folder, is there a way to reset it or something? ANY other folder to default to would be less annoying. I do not understand why it seems "stuck" on this folder and will not preload ANY other folder from the dozens of folders.

Thanks in advance for any help!

I'm using Firefox 115.15.0 ESR with a MAC M2

When I visit jsonviewer.stack.hu and paste data into the viewer I get the following error:

TypeError: netscape.security.PrivilegeManager is undefined

Please type: "about:config" in your address bar. Then filter by "signed". Change the value of "signed.applets.codebase_principal_support" to true. You should then be able to use this feature.

As config is sensitive area of the settings can you guide through this problem with a fix? Thanks bcoleman@sympatico.ca

Version: Firefox 129 Ubuntu/Debian I'm using the Proton theme in Firefox and would like to revert the tabs to their previous, non-floating style. I've tried using the [profile]/chrome/userChrome.css method and enabling toolkit.legacyUserProfileCustomizations.stylesheets, but this hasn't worked. Is there another way to achieve this? Thanks for your help in advance!

Why Firefox is unable to bring customising options for homepage and toolbar for mobile users in all these years despite other browsers upping their game with user feedbacks and newer browsers bringing exactly what the users want?

Big phones, too many bookmarks, can't remove or hide home button icon on URL bar, no download manager, no options to add home shortcuts or speed dials on Firefox homepage no navigation buttons at bottom, no DNS, is this Firefox in 2024 and 2025?

Hi community!

For some reason, the short description of an email is now under the subject instead of besides it in the overview. This does something to my head that, atleast for me, makes it cluttery and hard to hover over who sent me email. I want a column with who sent me mail, then I want right of it a short description, the start of the mail, just like it always was. It takes vertical space so less email is visible and my head has to switch from "from" to "content" to "from" to "content" which is for some reason very tiring. It's one of the reasons I hate outlook... Please don't tell me Thunderbird changed into outlook -_-

How do I change this back to the way it was?

This recently happened on Firefox for my laptop and the characters are broken. I've tried re-installing and removing the files Application Support/Firefox, but the issue still persists. The language is set to English CA. Can anyone help with this please?

Device: Macbook Pro - M3 Chip - Sonoma 14.5

I tried following these steps but it didnt work. Is it possible to turn this off in about config or hide it with a userchrome.css style sheet?

The interface for Multi-Account Containers has changed. How do I manage the containers. Specifically, how do I create new containers and delete old, unused ones? Put the Manage Containers button back with the old buttons.

With my previous FF installation, it would remember both the width and the last selection in the sidebar after closing and re-opening FF.

I just formatted and reinstalled windows and now FF simply would not remember the last sidebar condition.

I'm using Windows 10 22H2 and FF 130 64-bit.

I posted it on bugzilla too, so any kind of help is appreciated, I am tired of resizing it multiples times a day.

Steps to reproduce--> Add 'Show sidebars' to the toolbar using toolbar customization. After opening the sidebar & then bookmark panel in it, I decreased sidebar's width to the minimum by dragging the border.

Actual results--> After sometimes[opening and closing firefox a few times], sidebar's width resized itself to the default [here I didn't change anything, 'bookmark panel' remain selected]

Expected results--> Width of 'Bookmark panel'[or any other panel] in the sidebar should have remained of the width it was resized manually.

Hello Firefox friends o/

Anyone knows how do I make https://yandex.com my default search engine? (in the top bar of the browser). I have attached a screenshot of my settings page. Please have a look at the suspicious lack of an "Add" button 🤔. Despite my efforts, the drop-down menu will not show the available options in the screenshot, you will have to take my word for it, the only available options in that menu are: Google, Bing, DuckDuckGo, eBay and Wikipedia (en).

P.S. The settings page in Firefox must change really often, as I seen so many people suggesting many outdated methods online.

I recently updated to ESR 115 and then to ESR 128.2 and I noticed that there's no Ublock Origins icon. I checked my settings and was shown to a window of installed and suggested add-ons and there I found an entry for Ublock Origins with a blue on button marked, nevertheless, I can't find where it is and I can no longer find any window showing what it's blocking.

I've read about this in earlier threads, one from 2019, one from 2021.

I would like the Ublock Origins to be visible and also to be showing what it's doing. It used to show a number of hits that would go up with each website that was open, as it was blocking things.

I'm using a win64 windows 10 22H2

The attached picture is of what I'm NOT gettting. It's from a website describing how ublock origins normally looks.

Thank you.
