Firefox Community Forum

Several extensions were recently deleted without my input. Among them were Duck Duck Go Privacy Essentials, Keeper Password Manager, and Apple's iCloud Password autofill. I know there were others, but I cannot even recall which ones they were. Not sure if this happened after the most recent update or later, but it happened at some point in the last 24 hours given that today is 3-15-2026 12:30 pm PST. I only discovered this when a tab popped up in Firefox asking me to complete a survey as to why I uninstalled Duck Duck Go Privacy Essentials, which in fact I NEVER did. See attached pic. Nor did I uninstall any of the aforementioned, et. al. Thanks Mozilla for f'ing up my settings and overall browsing experience across all of my devices without my consent.

When I try to go into my google account for any reason and a few other websites, it will say use passkey or try another way. I have done both several times and Firefox ALWAYS FREEZES and I have to force quit. I have reinstalled Firefox, gotten rid of all cookies and cache, gotten rid of extensions and everything I could do from the help website but nothing seems to work. I have also reinstalled Firefox but the same thing keeps happening. I need HELP!

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!

I'm suddenly having a problem where images don't save as .jpg unless I add that myself. At first, it wanted to save images as WebP, but I was able to fix that in the about:config. Now when I go to save an image, it wants to save as Chrome HTML document and I have to click all files and then add .jpg.

Hi, I opened Firefox to continue with my work, just to get greeted with a 'start a new profile' page. All my profiles, saved data, history, add-ons and customization, were discconected/removed. Even on my phone it logged me out from my account- logging back in doesnt retrieve my history from my previous sessions on my desktop device.

I tried logging in to my account, checking if theres an 'old firefox' folder on my device or anything like that, but it did not retrieve any of my old data.

Just to clarify, I have not played around with my settings, left or deleted anything, so I really dont understand why I've just came back to nothing.

Was wondering why this happened, how do I know this won't happen in the future, and if, when possible, how can i get all my data back?

Thanks

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

Hi Had some problems with the computer. According to Microsoft the dll error was caused by the new Adobe acrobat. Trying to fix this problem some of the websites in Firefox are having now problems. EXP. Kohl's Error code: SEC_ERROR_REVOKED_CERTIFICATE. Home Depot Oops!! Something went wrong. Please refresh page. This is only happening in Firefox with Windows 7, Firefox version 115.33.Oesr 64 bit. When I access these two websites on Chrome in the same computer everything is fine.

What is causing these errors in Firefox????? Can you please help!!!!!

Since changing to a new internet service provider, I can no longer print form Firefox. My internet router uses the same username as password as my previous router.

Whenever I open a new firefox page externally, such as from the system tray or by opening a link from outside firefox, nothing happens for about five seconds and then it loads normally. When I open a new firefox page internally, such as from file ---> new window or by clicking a link within firefox, it loads instantly like normal. This has been happening since yesterday (3/13/26) evening.

I have already tried all of the following fixes and none have done anything:

Clearing firefox startup cache running firefox in troubleshoot mode running an older version of firefox disabling all my extensions disabling my antivirus disabling hardware acceleration disabling captive portal detection making sure both firefox and windows 11 are fully updated refreshing firefox reinstalling firefox rebooting my PC disabling IPv6 preventing accessibility devices from accessing my browser clearing my cookies

When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

1. "Apps > Default Apps"
2. .mp4 (for example)
3. click the button below that displays the current default application
4. Firefox Nightly appears in this menu
5. "Choose an app on your PC"
6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

javascript contains the following code:

var txt = "<tr><td" if (SecIndent[i] > 0) txt+= " class='In" + SecIndent[i] + "'" txt+=' onclick("' +'go2('+ "'_" +i +"')"+ '")>' +SecNames[i] +'</td></tr>' alert(txt) // txt += ' onclick("go('+"_'><a href="#_'+i+'">'+SecNames[i]+'</a></td></tr>' document.write(txt); }

seems to be working right -alert displays: <tr><td onclick("go2('_3')")>Chapter 1 – The Number Tiles</td></tr>

when I inspect element it shows <td onclick("go2('_3')")="">Chapter 1 – The Number Tiles</td>

where did the extra =" come from? when I tried other browsers still problems but inspect element was different hopefully this isn't a Windows 10 problem, but very wierd if it is
