Starting with version 126.0.0, firefox for MacOS stopped creating a defaults/pref folder during installation. If you create it yourself and add the autoconfig.js there, and add firefox.cfg to the root, firefox reads them perfectly and applies the settings. However, if you create folders before the first launch of the browser after installation, the file integrity check fails (see screenshot).

I couldn't find any information about why the folders stopped being created. Maybe someone knows?

The newest article regarding the configuration seems to be this one:

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!

I use multiple dialing apps in my business. When I choose a specific app, it opens in the same window as my source data for the call. I have recently began using a new computer. In my previous computer the dialing app I chose opened in a new tab. Please help.

When I'm using Firefox Multi-Account Containers with the option "Limit to designated sites" enabled, I encounter an annoying issue when navigating between different subdomains of the same website.

For example, if you navigate from "https://www.google.com" to "https://accounts.google.com," you will exit the "Google" container until that subdomain is manually added to the container.

I thought it would be nice if I could somehow create a container for "https://*.google.com/" (where * acts as a wildcard, as explained in the note below).

• Is it possible to do this? If so, how, and what is the safest way? (See note below)
• If not, is there any viable solution to this problem?

Note: The RegEx (or wildcard) * should only allow alphanumeric variations to prevent security vulnerabilities. For instance, "https://www.PhishingSite.com/WeStealYourAccount.google.com" could bypass the container if * is not restricted properly. In this case, * could mistakenly refer to "www.PhishingSite.com/WeStealYourAccount"

Thank you for your help

Not long ago all my search queries starting showing up in French instead of my default language English.

Every time I click Change to English I get taken to Google's Search Settings with NO indication where to make English the Default language. When I click Parametre de langue I am taken to the Google Search Settings - Language and region. Here I change Language of display to English...., but when I close the window and start up again it jumps right back to French.

It's driving me nuts!

Hope someone can assist me :-)

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.

I have always been able to save my bookmarks to a folder called "Other Bookmarks". I can't remember if I created it, or it was there. Until this last update (130.0), this folder was my default folder, and all the bookmarks were saved there automatically. Now, for some reason, all of my bookmarks are being saved to the Bookmarks Toolbar, which I don't want to happen. I've tried setting the default back to the "Other Bookmarks", but for some reason, nothing works. I've tried 3 different ways of doing it. This only started to happen after FF automatically updated. Any help would be appreciated.

I have the current 130.0 version and I am using Win 10. For several versions now I have been unable to print the date as a footer. I have read the Firefox help on this issue and not resolved it. &D is shown for footer-left, and footer is enabled in the print dialog. Can anything be done?

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.?

System is Ubuntu 22.04 LTS. Firefox 130.0 is the browser. When printing PDF forms from a website, the printer dialog shows the paper size as US Letter, but it prints as a tiny version of the document.

When I dig deeper into the printer dialog, the page setup is listed as na_letter. When I change it to US Letter, the document will print correctly, but it reverts to na_letter for subsequent print jobs.

The printer is a Brother inkjet, MFC-J985DW. This problem only started recently and the only known changes have been automatic Firefox updates. Any suggestions for a fix?

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.

Opening bookmark folders with middle click automatically switches to the tab of the first bookmark in the folder.

The config settings:

• browser.tabs.loadBookmarksInBackground
• browser.tabs.loadBookmarksInTabs
• browser.tabs.loadDivertedInBackground

All set to true seems to only affect single bookmarks, i.e. bookmarks that are not folders.

Why is this still something that can't be configured? Mozilla please add some support for this.

Has anyone found a fix for this issue? All help is very welcome, thanks in advice.

Since installing the latest version of firefox all the web pages are in dark mode even though everything is set to light mode in settings and themes. A lot of the sites are not designed to be in dark mode, they look horrible and some buttons/text are not visible unless the mouse is hovered over them. Strangely these support pages are the only ones in light mode. Please help

I hope my question is self- explanatory.

After a number of years away - I am returning to use Firefox - I believe in it's philosphy - but moving back from Microsoft Edge which is just too commercial, I am seeking to make the changes to my ways of working as few as possible. I use the history page a lot as a memory aid because I have short term memory difficulties caused by neurological develeopmental disability.

I also tend to say more than may be necessary!

Thanks for any responses.

FireFox 129.0.2 (64-bit) - This issue persists across updates.

If a YTTV tab is left inactive for a few minutes, the keyboard shortcuts (ex: 'm' to mute) stop working until the page is interacted with again using the mouse (clicking on mute/volume, stop/start the stream etc.) The stream plays normally otherwise.

I'm not sure if this is related to YTTV, Firefox, extensions or Windows (Win 10 Pro)

Extensions: UBlock Origin, Privacy Badger, MalwareBytes Browser Guard, Old Reddit redirect and Reddit Enhancement Suite

15-30 tabs are normally open. Firefox is currently using 2.5Gb memory (32Gb installed).

Privacy Settings are set to custom (image attached).
