I recently updated my MacBook Pro to the latest MacOS (Sequoia). Though I didn't notice it immediately, today when I opened Firefox, all text is displayed in a foreign character set. It is pervasive - I've tried to use several tutorials to reset the language and all settings to default, but so far nothing has worked. I've uninstalled Firefox using AppCleaner (which gets any leftover files in OS folders, as well as the app itself), but a clean install results in the same issue. I've disabled all add-ons and reset all settings to default as near as I can tell. The only time the browser displays properly is when it's in Safe Mode. I'm not sure if this is related to the OS update, but I can't seem to identify any other recent change that could have the potential to cause this problem. Any suggestions would be greatly appreciated.

I've never had sponsored shortcuts and suddenly today I've got them. I've attempted the disable the "sponsored shortcuts" on my desktop however its greyed out.

Starting state - Shortcuts selected, sponsored selected and grey Procedure: 1.) Deselect shortcuts, select shortcuts, sponsored becomes cyan 2.) Click sponsored, it becomes grey again 3.) Deselect shortcuts, select shortcuts, sponsored becomes cyan (again) 4.) Click sponsored, it appears deselected 5.) Hit refresh and it returns to starting state

I do not edit my GPO or registry, settings are not controlled by an organization, I am not confusing sponsored shortcuts with pinned search engines.

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

I tried to use a ftp link setting firefox as the default ftp app, not realizing firefox no longer supports ftp. I am unable to reset the default app and can't find the setting to do so. I downloaded filezilla and wish to set it to be the default app for ftp. Can someone help me with this? Before anyone suggests it, resetting firefox to default settings is not an option.

I'm on v137 on Windows 10.

I cannot play my Unifi camera videos because they require HEVC. I thought v134 and higher had HEVC support?

There were some mentions of needing to get the HEVC codec from the Windows Store, but I could also not locate that from Microsoft either.

Under about:support, it says HEVC is Unsupported. What am I missing?

How do I enable JavaScript on your browser? I’ve tried searching about:config It doesn’t work!! Please reply to: [edited email from public community support forum] Thanks, Linda

For some reason Firefox remembered my phone number and is now trying to use it as a login when I attempt to login or register in any service. I've checked my saved passwords and autofill data, but I cannot find it, there's only usernames and passwords, and I have no saved autofill data, no phone number. Where can I look for it to remove it?

Helllllllllllp! Just had firefox install an update & now all my saved bookmarks, login passwords & previous home page have all gone. Have reset Home page, checked that Profile is correct & the bookmark folder is empty. Where have they all gone. Yes I have restarted my computer but made no difference.

How to change home page and new tab to desired URL or any extension of Firefox desktop in 2025?

I am unable to find any way to change how my new tab should look when I click + sign or new tab is opened up on browser opening or re-opening unlike Chrome.

I hate the change of position of typing from the search bar on the current new tab to the URL bar (unseen or unheard in Chrome) that Firefox implemented without considering users who would detest it.

Using Firefox 131.0.3 (64-bit)

For several months I have been getting all these woke "news" popups from Firefox in the bottom right corner of my PC screen. I use firefox as my default browser and don't feel like uninstalling, but soon I will have to because it is so annoying when I am trying to play a game and firefox comes along and tries to brainwash me with its woke agenda. I mean, today it's giving me a popup telling me to go plant-based for a month, WHEN IT'S LITERALLY CARNIVORE MONTH. HOW DO I REMOVE THIS BULL****!?!?!?

There are 4 toolbars at the top of the Firefox screen. The default order from top to bottom seems to be:

 Menu bar
 Tabs bar
 Navigation bar
 Bookmarks bar   (which Firefox apparently calls "PersonalToolbar")

I would like to move the Bookmarks bar above the Tabs bar so the order is;

 Menu bar
 Bookmarks bar
 Tabs bar
 Navigation bar

I tried to use ChatGPT to accomplish this. After well over 6 iterations, I gave up (ChatGPT was still going strong - hallucinating?). The only code in userChrome.css that accomplished this is shown below. Unfortunately it leaves the order as:

 Bookmarks
 Navigation
 Menu
 Tabs

Can a human expert help me where ChatGPT failed? ___________________

/* Move the bookmarks toolbar above the tabs */

1. navigator-toolbox {

   display: flex;
   flex-direction: column-reverse;

}

Hello, how can I remove or hide "List all tabs" btn?

Set "browser.tabs.tabmanager.enabled" as "false" stopped working for me after update to version 131.0. Hiding the btn before version 131.0 was not a problem.

I saw in release notes that "List all tabs" got some changes. link

My husband's Windows computer failed, and I am setting up his new Chromebook as a holiday gift.

Unfortunately, the instructions for setting Private Mode as the default for Firefox don't fit what I see on the Acer Chromebook 315.

Please provide appropriate instructions. I want to place it in his office, ready to go, before he gets up tomorrow morning, December 25. I am in Central Time in the US.

I'm having some trouble with automatic translations on firefox. I don't know if It's exclusive of firefox, but some websites, mostly wikis, open a "translate" field that automatically creates a new website, wich causes the images and some other stuff on the website to break. I tried disabling the translation on about:config off, as show in some other questions, but it did not work. This is being really annoying because it keeps breaking websites unless i get to the original link.

Why it disappeared? It was always there. I am logged in Pocket and tried to restart Firefox. Maybe it has to something do with recently added AI side panel? It seems that since then my Pocket icon is missing. Browser version: 140.0.2 (64-bit) OS: Linux Mint MATE 21.3 (Virginia) Kernel: 5.15.0-143-generic

I prefer the tabs be below the bookmark bar, and successfully modified the CSS file to do this some time back. Now update 133 has once again pushed them up below the menu bar. What do I have to do to get them back where I want them this time? And why can't you just leave the tab location preference alone when doing updates?
