It seems that my Bookmarks are opening SOMETIMES back onto itself. How do I adjust my settings so they don't seem like they overlap back onto each other? Wasn't sure if this was a Firefox setting I overlooked or a Windows 10 problem. Hopefully the attachment clarifies it more.

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!

Hi, I like to use the Inspector window to modify layouts for printing &/or save as pdf only portions of a page or a whole page that's not laid out in a printer friendly way. Lately in the "Rules" pane of the Inspector window, I've noticed something I've never seen before. Normally it shows a list of rules for properties, attributes, etc...(CSS) which I can select or locate and change/modify with virtually no problems. Lately in that pane I've been seeing an item with an italicized title "element attributes style" and a lock icon on the upper left next to that text and it doesn't show show a link to the CSS page on the right side, nor does it allow me to select anything within. Does anybody know about this ?...is it some new setting or something that's changed in the newer versions of the browser. A couple of months ago I updated FF, which I hadn't done for awhile, and also just by chance, since that update I hadn't really used the Inspector for one reason or another, so I'm wondering if it's just a coincidence, since I had never seen it before. I'd appreciate any info or opinions about this. Thanks and wish everyone all the best.

The bookmarks icons and fonts are too small for my older eyes on my new Ubuntu computer. They are bigger on my older Ubuntu computer. I have tried to find out how to enlarge them without sussex.

I am aware of the Zoom feature for a webpage itself, I am not asking about that. I simply want to have my bookmark toolbar FONTS and ICONS larger.

This has been frustrating. Perhaps including an EASY way to do this for future updates, or an app suggestion that would solve the problem. Thanks for your consideration and (hopefully) help.

I see a notification dot with the number "1" inside, on the Firefox icon - but have no idea where to go to see the notification referred to. Can anyone please describe how to navigate to the notification?

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.
