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.

Firefox does not allow Amazon to record browsing history. I am not in privacy mode. I once had Firefox set up to do so. Can you tell me what changed (what to change)? Edge and Safari allow the exchange; so it's something in Firefox

When I click a link or open a new Tab Firefox opens a new window. I have Firefox and Thunderbird pinned to the Taskbar and usually switch between them easily. Today when I try to switch to Firefox another FF window opens. Why is this happening and how can I stop it.?

All of a sudden, my extensions icons, site icons and some images in every page are very very dark or pitch black. I haven't change anything in themes other than changing the theme of the browser after installing it.

In the attached images, you can see how the Mozilla site icon is rendered by Firefox Stable, Firefox Nightly in Recovery Mode without my account being signed in and Google Chrome. The other screenshot is the extension toolbar with extension icons being rendered all black instead of their true color.

The other day I accidentally pressed a keystroke that changed a Firefox setting, and now it thinks I'm on a mobile device/displays sites in mobile view where possible by default. This has persisted despite restarts of the browser and the computer and has been happening since Sunday (Australian time). I've tried opening the Responsive Design dev tool and I've sent screenshots to a techsavvy friend (I'm totally blind and use a screen-reader, so couldn't tell this was happening until I tried to use a site that had a radically different layout in mobile view), and aside from not seeing an exit button or a switch to change device mode, he couldn't tell what was going on.

I'm stuck and need help! I would like to unmobile my Firefox!

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!

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.

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 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?

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.

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.

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?
