I-Firefox Community Forum

For the last 2-3 day I have been experiencing a box that asks for my signature each time I go to a new website. I can't move the box. I can't screenshot it. Does anyone know how I can get rid of it?

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!

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

1. 1. Steps to reproduce

Open several tabs, in settings, check «ouvrir les fenêtres et onglets précédents», quit firefox.

1. 1. 1. Expected behavior

On startup, Firefox should reopen with the same tabs before shutdown.

1. 1. 1. Actual behavior

Firefox opens with one empty tab. Forcing me to got to «history -> recently closed windows -> restore» everytime I quit Firefox or shutdown the mac.

Fresh migration from Win 11 to Mac. tabs, passwords, bookmarks, plugins migrated from win to mac. Attachments:

Lost my Passwords on my desktop and can't recover them through profile manager, I found them on my android phone and want to recover my passwords from there, but am worried if I try and sync to the desktop, the desktop might overwrite the passwords in the phone.

The last 2 days when I have shut down my computer then restarted, my Firefox profile has disappeared, along with all my bookmarks, passwords etc. I spent several hours yesterday following all the advice here to get everything back, but nothing worked. I had to create a new profile and then import an old passwords file, which I luckily had saved in Excel. This morning when I switched the computer on, the same thing has happened. I cannot even open Firefox without creating a new profile. I get a pop up box (screenshot attached), which shows no profiles, and i have to create a new one to even open Firefox. Every time I close out of Firefox and want to go back in, I am asked to choose a profile. This has never happened before.Before i give up forever on Firefox and go over to another browser, do you have any ideas how i can stop this from happening, and get my original profile, passwords, bookmarks etc back? Thanks.

I'm running Linux devuan: Linux MikesPI 6.1.93 #1 SMP PREEMPT Mon Dec 8 02:37:53 CET 2025 aarch64 GNU/Linux and Firefox 140.4.0esr (aarch64).

For years now I've been downloading and saving Yahoo quotes as csv, now for the last week Firefox wants to save page image poping up an extra window that must be refused before I can continue using Firefox. Hopefully someone can tell me what new option in about:config can be turned off to stop this. Thanks, Mike

on my laptop the firefox search engine randomly changes to one that I don't even have checked as "search shortcuts" but are still on my "default search engine" list for some reason (but never chosen by me

Tell me a working method of getting firefox to change my password so as to stop me having to sign in every time I need to use it. Worked before but doesn't work now.

I noticed that after the latest update, searching with the address bar no longer works as smoothly: autocomplete suggestions only appear in the bar when typing in a single character on a new tab, rather than updating with each additional keystroke. The suggestion only appears upon unselecting and reselecting the address bar. (see uploaded images)

Also, the search suggests seem to regenerate the entire dropdown menu with each keystroke, resulting in an unpleasant "flickering" appearance. It's not the biggest deal, but I don't recall firefox (mis)behaving this way before.

Can anyone help me with this?

I am seeing pop up ads like these on the lower right corner of my screen since I updated to windows 11. I've never seen this with windows 10. Microsoft is telling me these are coming through my browser. These are not when I am in a web site and get the pop up to allow notifications, I always say no. These come @ 1 per week or less and I don't seem to be able to stop them. Is there a setting in firefox that will stop them or is this a microsoft issue? thanks brian

With dailyexpress.co.uk using Firefox there are two pop ups. One is breaking news on each page using right links and the other is a subscribe to read any of the site, which is recent but prevents reading the site. This does not happen using Microsoft Edge.

I am currently trying to set up automatic backups to a local network folder. I have set browser.bookmarks.autoExportHTML and browser.bookmarks.file via the about:config page. This creates the backup on X:\bookmarks.html as desired, but only this one backup. Is there another way to create the backups with a timestamp and to keep to the maximum number via browser.bookmarks.max_backups?

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?
