Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

Description: I need help with the "Firefox Multi-Account Containers" extension.

The extension is installed and shows as "enabled" in my Add-ons Manager. However, the colorful container icon does NOT appear on my toolbar, so I cannot access or use the extension at all.

What I have already tried (none worked):

· Dragging the extension icon from the puzzle menu to the toolbar · Right-clicking on the extension icon (inside the puzzle menu) to see if there is a "Pin to Toolbar" option — but the option does NOT appear at all · Restarting Firefox multiple times · Restarting my computer · Creating a new profile in about:profiles and testing the extension there — still no icon · Disabling and re-enabling the extension

The extension is installed and enabled, but without the toolbar icon, I cannot create containers or separate my Gmail accounts. I really need this feature.

I have read that this might be a bug in recent Firefox versions. Is there a known fix? Do I need to completely uninstall Firefox and reinstall it? If so, could you please guide me on how to do a clean uninstall (removing all profile folders and registry entries) and then install the latest version?

My system is Windows (older version, if that matters).

Thank you very much for any help!

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

Hi everyone,

I’m running into a frustrating issue where Firefox is opening PDFs in two places at once.

The Problem: When I click a PDF link, Firefox opens the file in a new tab (internal viewer) but also launches the standalone Adobe Acrobat app to display the same file. I only want it to open in Firefox.

Details: - Settings: My "Applications" setting for PDF is currently set to "Always Ask." - The Glitch: Even when I manually select "Open in Firefox" from the prompt, Adobe Acrobat launches anyway. - Timeline: This started happening 2 days ago without any manual setting changes (I think it might be after a firefox update? I might be mistaken)

- Troubleshooting done: I have tried toggling the action to "Open in Firefox" directly, but the dual-launch behavior persists.

Thanks

There seems to be no possible way to change the shortcut for peeking at the tabs in the sidebar (when sidebar revamp is enabled) from the about:keyboard UI. I have so far managed to modify the shortcut through intercepting function calls.

What I have done: 1. Read through the JS source code for about:keyboard which says the shortcut ID is `toggleSidebarKb` 2. Added hooks to intercept `RPMSendQuery` calls 3. Modified the shortcut through devtools open on the about:keyboard page with the following snippet

```js await RPMSendQuery("CustomKeys:ChangeKey", {

 "modifiers": "accel",
 "isValid": true,
 "key": "S",
 "shortcut": "Ctrl+S",
 "id": "toggleSidebarKb"

}) ```

The way I am doing it is definitely a hack. I am not sure if I am missing something. Although the shortcuts for bookmarks, history, and GenAI chat sidebar are present, there seems to be no entry to change the sidebar toggle shortcut itself. I'd love to work on this but I haven't been able to mach bootstrap on NixOS.

Thank you for any assistance :)

I can't save my tabs & windows anymore, I have the box checked but after I close down the computer I lose all the tabs when I reopen and then I need to put them all back manually. What has gone wrong it always worked before for many years? Please tell me how to fix it

Good evening. I have had to install my FF after a system repair. I have everything set back except when I click on a link and hightlight an item with my mouse and right click it opens a new tab. But before where it would just open it changes to the new tab immediately. Under settings I have the 'when open new tab switch to it immediately' unchecked and I was directed to four settings on about:config including browser.tabs.loadDivertedInBackground to set to true. I did and the behavior did not change. Any suggestions would be helpful. Thank you.

Ce matin,09/03, ORANGE a mis en place une nouvelle messagerie qui ne passe plus sur FIREFOX mais que j'ai retrouvée par un autre navigateur. Tous mes contacts avaient disparu ainsi que les messages reçus ou envoyés.

Warum fordert FF bei Anmeldung in Ebay, Kleinanzeigen immer das PW und anschließend noch eine Bestätigung über mobil Funk. Das war vor 2 bis 3 Wochen nicht, es nervt. Weiterhin werden die Bilder in Ebay kaum noch gezeigt. Sytem Win 11 auf PC

Dear Support Team,

I am currently experiencing a very frustrating issue with Firefox. I have been using it for many years, and it has always been my preferred and most comfortable browser for my daily work. I depend on it heavily, as all my bookmarks and other important information are stored there.

Over the past few weeks, Firefox has been crashing more than ten times a day. I have already tried all the troubleshooting steps suggested in forums and through AI-based support, but none of them have resolved the problem. I also attempted to install and use the Firefox Beta version, but the issue still continues.

In our environment, other users and devices are not encountering this problem, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please assist me in troubleshooting this issue? I have attached the error screen that appears after the crash along with the crash report for your reference.

No reports shows on about:crashes

Best regards

I cannot log into Facebook with my Firefox browser. Even though the username and password are entered correctly, the login freezes and I cannot proceed. I am able to access the site on other devices. On my laptop, I deleted all cookies, history, and cache as recommended. I am able to log in to Instagram on this device. Coincidental to this problem: when I try to view video on newyorktimes.com, the browser freezes. I cannot view content in other open tabs and must reboot the browser.

In the last week or so I have noticed that when I go online to to purchase something or just browse for items, my location has altered from UK to Ireland. I wondered if anyone has had the same experience and maybe has an answer to help me.

My shortcuts keep disappearing from my home page when I turn my computer on. Sometimes it's fine, sometimes I have to spend a long time trying to find them. Sometimes I just have to restart Firefox. Sometimes I have to go into settings. Sometimes I can't work it out.

Has been happening for the past month or so.

I've always used firefox

Recently it seems to me that a lot of sites don't seem to recognise me, so I have to do multi step logins.

Paypal for instance. I don't save the password, I type it in each time, but now it insists on sending me an SMS in addition

My guess is that FF is deleting some cookies that I'd rather it didn't. What can I do?

Thanks

Youtube webpages won't load properly after saving. They start to load but then switch to a white page. I need to be able to save a video's webpage to save links and other information for later viewing. This started happening on any computer 2 or 3 months ago. I'm thinking that youtube did something that causes the saving of their webpages to be messed up. Youtube webpages display fine on youtube.com but saving their webpages doesn't work anymore.

I've been trying to decipher browser.tabs.insertXXX with little success. What I want to achieve is to open tabs from the same site next to the current tab with the most recently opened tab next to the original tab.

Example Two tabs are open, site 1 tab 1 and site 2 tab 1. Open a new link to site 1 on site 1 tab 1. The order is site 1 tab 1, site 1 tab 2, site 2 tab1. Open another link to site 1 on site 1 tab 1. The order is now site 1 tab 1, site 1 tab 3, site 1 tab 2, site 2 tab 1.

Thanks in advance.

I have emptied cache, reset everything and I still get

This is from Cabelas.com but I am getting it more and more from other web sites. American Airlines, Delta.com, etc. I accessed the help and did all the steps about fingerprinting and turning off "enhanced tracking protection" and nothing helps. Any ideas? Don't like the idea of using Chrome or Edge, but Firefox is almost unusable for me now. If I have to keep using another browser for the sites, may as well just use that one only.
