Firefox-Hilfeforum

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!

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.

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?

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 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.

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 :()

New install of Firefox set up with a 'wrong' email account. Tried to use the 'Mozilla account' page to fix this by using secondary email and then making it primary. But the secondary email I want to use is not allowed by Firefox giving an 'Account already exists' error. What should I do?

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.

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

I just bought a new laptop and downloaded Firefox as I have used it for years. Although I imported my passwords and they are correct it will not log in to sites I need for work. It isn't telling me I have the wrong pw or id, it just does nothing.

I have updated windows, I have uninstalled and reinstalled....I don't know what else to do...any suggestions?

thanks

When logging into an account there are multiple usernames (incorrect or older.) I would like to remove or delete them, but keep the current passwords.

Is that possible without deleting the account?

Thank you, rldelahay

Any help to fix this issue would be great.

Always shows "Failed to check for updates" On version 125.0.3 and still says needs to be updated. Then just run the install again and then it stops for a bit still on same version and then shows up needing update...been doing the same thing for a while now.

My "recovery.jsonlz4" file from a previous install will not reopen my previous session (tabs) after the new installation.

Before deleting my previous installation of Firefox (for a clean install), I did two things: I created a restore point, and I did a backup of my old data.

The data consists of: bookmarks-2024-05-10.json

These folders: C:\Users\[machinename]\AppData\Local C:\Users\[machinename]\AppData\Roaming C:\Computer Files\Mozilla Firefox\distribution C:\Program Data\Mozilla-1de4eexxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Within "Roaming" I have Firefox\Profiles\xxxxxxxx.default-release\sessionstore-backups

In that sessionstore-backup, I have a "recovery.baklz4" (most recent session, I'm guessing) and three others that look like "upgrade.jsonlz4-2024xxxxxxxxxxx

With Firefox closed, I took a copy of "recovery.baklz4" (745 KB) and pasted it into the current sessionstore-backups file, then I changed the file to "recovery.jsonlz4".

I thought that when I reopened Firefox, my previous tabs would appear. They didn't. So, I went to the menu, then to History, and clicked on Recover Previous Session. That didn't do anything either. And it reduced the size of the *.jsonlz4 file from 745 KB to 6 KB.

I'm not sure what I've done wrong. Can you help me out?

Thank you.

using Win 11, Firefox browser, Google search. subfolders are listed but will not open. Using Bing they do open but I prefer Google. If this is a Google problem or a Win 11 can you steer me in the right direction. Thanks My email is artsiii@aol.com
