I do not care it it’s optional. I do not care if there is a “kill switch”. Firefox should not be wasting it’s time on these features in the first place, as it has been nothing but an active detriment to the user experience on every platform on which it has been implemented. Nobody asked for this. Nobody wants this. I installed Firefox because I saw that it was different from other browsers, mainly in the way that it was not following the latest tech fads straight off a cliff. If the new leadership decides to change that, then I see no reason to stick around.

My firefox recently crashed (f5ea38ba-f4f8-4224-8ab8-982e19cc72f7) is the crash code if that helps it happened just now, i dont have any additional profiles and no folder such as "old firefox" is there any way i can recover all the information and my old settings or passwords or anything? I tried to log into my firefox account to sync up data but there was no update on the information

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

If I don't use the custom adjustments in my Chrome css, seven buttons on that right side of the menubar are hidden, including the min-max close buttons.

This is problematic when I'm troubleshooting Firefox, and the css is disabled. If I want to close or take the browser out of max mode, I must move those buttons to the navbar, which has no such restriction accommodating those buttons, not to mention why is it necessary for that min-max close trio to monopolize 20% of the menubar. Waste of space. Inefficient.

I'm also curious why must that frame at the top of this sites pages remains persistent, and follows the user down the page, so that when you're composing, and accidentally (and all to often) touch one of those links, it get superimposed over the message, and you must move the cursor to the bottom of the page get rid of it. Not to mention, that frame shrinks the working area of the page about 30% vertically.

I mean, once you have already navigated to the destination page, and you're composing, how often/likely are you going to need to access that area?

Firefox fails to show short cuts in browser page and verified shortcuts is checked and can't find top sites settings. I previously had this show up every time I open Firefox.

I can't find a place to manage my payment methods. The only place I found that was when I check out and fill in my information in a store website.

The browser suggests my card and under that it says "Manage payment methods".

When I click that it opens "about:preferences#privacy-form-autofill" and then quickly becomes "about:preferences#privacy".

Please help thanks

When I choose to bookmark a website, I am no longer offered a chance to save to where I want it saved.

FF 146.0.1. Windows 10 pro

So, now I have to bookmark a page, and open the bookmark menu again to EDIT the bookmark to move it. This is Horrible. I have to do this eachj time I bookmark a page. I am veriy organized and have dozens of bookmark folder, some with folders within folders... etc.

Onliy children need to be treated this way.

I have searched the settings and find nothing. I am not using any add-on that has anything to do with bookmark. I do not use the bookmark toolbars or other bookmark interfaces. Just the file/edit... menu "bookmarks" option.,

Has this ability been removed?

Hello everyone! Windows 10, Firefox 146.0.1 (64-bit) I'm trying to synchronize my account, but there is no "Sign in to account" or "synchronization" function in the settings menu on the left. When I log in via the command line using https://accounts.firefox.com/signin, I can log in, but neither the account itself nor the synchronization button appears in the settings. What should I do? Thank you!

Greetings Ya'll,

I have to apologize if this is a double post, but I came back to the forum, & wanted to see if there were any responses, but i could only find my post listed under "My Profile"/"My Questions".

My original post was made Dec. 19-2025

=======================================

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all. Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?

What are your best tips for optimizing Firefox Desktop for daily use, especially in terms of speed, memory management, and handling multiple tabs without affecting overall system performance?

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

Desktop Computer. Still on Windows 10.

Not sure of category. This began when I launched the computer today. I opened Firefox and got the message "The bookmarks and history system will not be functional because ....."

When I started to shut down the computer (first mentioned step here) I saw there's a Window update. I selected Update and Restart. That went okay, but still don't have my Firefox bookmarks.

So I clicked on Learn more. I found the Firefox > Profiles folder. There are two folders, one from today - qkuxm6ws.default-release - 15...... 0196 with 94 items, and 7ghfiw 15.default, from Jan 5, 2021, with 3 items. I assume I should use the one with today's date.

BUT .... from this point, the information on this website was full of information - NOT step-by-step information telling me what to do with which files in this folder.

Also, I have McAfee as well as Windows Defender. I opened Windows Defender Firewall. State is On. Notification state: Notify me when Windows Defender Firewall blocks a new app. I've gotten no such messages.

Under allowed apps and features:

 "Firefox ... private not checked; public checked.."  
 "Firefox (C:\Program Files\Mozilla Firefox" - private is checked, public not checked.  

Can't make changes.

Under Overview window: Not checked is "Inbound connections that do not match a rule are blocked."

• • • • In the "Monitoring\Firewall folder" - Firefox (with path) is listed twice. Both entries have Private, Allow, NO Override -
      • Differences - the first has UDP; the second has TCP. Nothing under "Group."

My last bookmarks backup was Jan 2025. 😕 😟

I don't know where else to look or what to do. Please help. Kami

I'm getting announcements of a virus threat that purports to come from Mozilla Firefox. Usually one or all three of the attached small windows that say: 1. "Viruses Found. Antivirus notification. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 2. Attention! Click here to secure your data!. via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. 3. "System Warning!. Click here to remove them! via https+++d512ucanaffc739fe48g.cgm-defender.pro" With a Dismiss button. I have run full scans and offline scans with MS Defender, but these warnings still appear. Is this legit? I suspect these are a virus of some sort. Either way, how do I deal with this?
