Firefox is not opening. Every time I try to use it, I get the message:

" We're sorry. Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts."

I have submitted the crash report: Crash ID: bp-51f17766-7a20-41dc-ae3d-27ab10240501

I am running it on Fedora 40.

Thank you!

I recently have gotten a message about manually updating Firefox on my Windows 11 system. Even after I updated, I then I started getting the same message and also "Failed to check for updates" in the Firefox "about" box and settings page.

I even went about uninstalling Firefox and reinstalling it while deleting the Firefox Program Files and user AppData directories. I also checked for a Windows Firewall entry for the program.

Is there something in another directory or registry setting I need to delete or change? Or does Firefox use a different program for updating that needs a firewall rule?

Thanks for any help.

When I launch teams or slack from firefox on windows, I presume that a slack:// and teams:// or equivalent url is launched by the webpage.

As a developer working on Browser Picker, it would be quite handy if I could inspect these urls that gets launched, is there a way I can see the actual protocol url that got launched somewhere?

when I search for a page after opening a tab. The page will load slowly then stop. I'll then have to hit enter again for the page the load. This does not happen with Chrome or Edge. Any ideas how to fix this frustrating issue. Thanks.

I installed an OBS plug-in for a virtual camera so that I could film my screen and pretend it's a webcam. I was able to use the virtual camera or my webcam on spelltable.com by selecting either from the dropdown "allow" menu. One day, I was no longer able to select my webcam. I could only select the obs virtual camera. I switched to MS Edge which worked as normal. I've uninstalled OBS and all plug-ins. Same result I've reinstalled firefox. Same result. I've been using MS Edge for websites that need my camera.

I have played "Hero Wars,Dominion Era " for years on Fire Fox...They did an "update" last week(Thursday or friday 04/25-26?24)and I haven't been able to log onto the game itself since...I can still open the Hero wars home page,I can get into my "discord" chat etc etc etc,but I cannot get into my individual game.(If it helps,my Hero wars game ID # is 10920140)...I had to start playing the game itself on Google Chrome...I am hopeing you can help find a solution as everything I do is from Fire Fox & I really don't like chrome :(...PLEASE Help me resolve this if possible! ( Nexus suggested I use "Incognito" on FireFox ( I remeber that from a few yrs back,but honestly,i haven't used or seen "incognito" since :()

I am able to start FF with no problem. I open a few tabs and then without warning I can't access any of the sites without closing FF and restarting. Then the whole cycle is repeated. I am considering getting rid of FF this started just over a month ago.

When I open Firefox and want to go to Private. I go to the three lines at the top right of the Firefox page. I go down to Private. Then after selecting it, YET ANOTHER REGULAR FIREFOX PAGE OPENS. I NEVER had this problem until the start of 2024.

Please help as I used to have FIREFOX PRIVATE as my go to browser. Now, I use others and they do not work with some pages.

Please help as it is frustrating to keep getting a new Regular page.

I have Ubuntu 22.04 (on a Dell Optiplex 3000) with a minimal installation. I downloaded Firefox 125, removed the SNAP Firefox and installed this Firefox with no issue. I can run "firefox --kiosk" and Firefox runs in kiosk mode with no issue.

I have made some changes in the "about:config" part of Firefox. I have also made some changes to the Ubuntu keyboard shortcut list. There is only one user created on this system and I have configured Ubuntu to login this user automatically upon reboot.

However, if I setup Firefox --kiosk to start automatically (I use the gnome-session-properties application to achieve this) and then reboot, Firefox does run, but it does not appear on the screen. If I enter the "switch windows" keyboard shortcut (ALT-TAB), the Firefox kiosk appears.

So, is this something I can fix by changing the Firefox configuration, or is it an Ubuntu configuration change. If so, can anyone tell me what I should do, or have an idea how to debug this?

A couple of months ago, I suddenly lost all my saved bookmarks, plus the ones on my toolbar. Strange thing is, all the folders and sub-folders I created are still there, they're just all empty.

Can I get them back somehow? I've been collecting them for years so can't replace them all!

Firefox 125.2 iMac OS x10.15

I'm using Firefox 124.0.2 (64 bit) on Windows, and every few days I get the error about using an older version of Firefox, with Exit or Create New Profile options. I then run "firefox -allow-downgrade" from the command prompt and everything works fine... for a few days, when it happens all over again. This only started happening a couple of weeks ago, but it's getting really annoying. How do I stop it (short of using something like Waterfox or Brave).

• Bulleted list itemI understand! You're asking how to use Mozilla Firefox or Safari. Here are some basic steps to get you started:

Mozilla Firefox:

1. Download and install Firefox from the official website. 2. Open Firefox and set your default search engine and homepage. 3. Use the address bar to enter URLs or search queries. 4. Explore the toolbar for bookmarks, history, and extensions. 5. Customize Firefox with themes, add-ons, and settings.

Safari:

1. Open Safari on your Apple device (it comes pre-installed). 2. Use the address bar to enter URLs or search queries. 3. Explore the toolbar for bookmarks, history, and sharing options. 4. Customize Safari with extensions, settings, and privacy features. 5. Use iCloud to sync bookmarks and history across devices.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

Hi Guys! Huge fan of Firefox since the early 2000s when I first learned about it. Way more secure, efficient, and lighter than any other browser (IE, Chrome, and now Edge). Firefox is my first download on every new device and my go to even on my iPad.

I've been getting this error message lately and I don't know what to make of it. My saved tabs are working normally (email, work, streaming entertainment). This automatically comes out on ever new start / re-start (Firefox is my default) on separate tab but I am not opening any new website. It's been 2-3 days. At first I didn't mind it but its consistently happening and not just a one time thing. I already cleared my cache data. I've also ran a scan and it's come up clean (I have a paid BitDefender subscription). It's also not the local ip of my machine.

So any help would be great as I really don't want to leak any personal data or have any viruses.

Thank you for your time!

Hi, I have been using firefox for many years and never showed me an UAC popup requiring permissions to update firefox as soon as i clicked the firefox icon in the taskbar. Today suddenly required it. I am administrator in windows 10, and have automatic updates enabled as always. I am using 125.0.3 (64-bit) version. This could be a bug or a virus? i am worried that could have given permission to a virus to install something else when i pressed the firefox icon.

daily mail website crashing right after opening..never had problems before

Dear People --- FIRST: I apologize for taking so ling. I had physical probs, that kept me from coming back. SECOND: I'm afraid that I can't solve this problem with the advice provided. There was a file mentioned [which slips my mind, and I can't look for it with out leaving this screen] that is supposed to be on my desk top. I couldn't find it, so things stopped there.

SO..... I'm reiterating my problem: I loaded an "update" to Firefox that was supposed to get around the obnoxious "THIS BROWSER IS NO LONGER SUPPORTED" message I'd get on certain web-sites [such as the Milwaukee Journal]. I never understood that, as I am careful to update programs, when the updates are available. SO: While I was on the Milwaukee Journal Site, I clicked on the "Firefox Update" that the Journal's site recommended. What happened was I got the Current Version, and LOST all of my add-ons. After problems I can't go into here, "The Cat's Back." Please advise whether I can get things back after this much time.

N.B.: I'm running Windows 10.

THANKX! C M The Gray Cat

When I press shift+cmd+D to bookmark all open tabs, instead of the links being saved to the designated folder, they are all saved to "Bookmarks Menu". The designated folder itself also appears with these links but it itself is empty.

I would expect shift+cmd+D to bookmark all links in the folder and the folder to appear in "Bookmarks Menu". This is what use to happen ages ago. I'm not sure what caused the change in behavior. Anyone have any ideas on fixing this?
