When I open Firefox, the tabs from the previous session do not open despite the setting. I end up with a start page showing only a new tab page. This has been happening over the past few days and I don't know why.

Does anyone have any ideas why this is happening.

I've read all of the recommendation on how to keep links from opening in another window. Tried them all to no avail. This is a new problem. Anybody out there finding the same issue? Find a fix?

I have a problem. When I access my Firefox main default screen I open up a respective website I want to access but within a matter of a few seconds the main default screen automatically opens up again meaning I now have two windows open which shouldn’t happen! I have opened up ‘Help’ and have refreshed Firefox a few times now. Additionally, I have opened ‘Troubleshooting Mode’ which comes up with ‘Restart’ then ‘Open’ and I have ‘Refreshed Firefox’ from this option. I have cleared my Cookies and Cache. I asked for help through the Firefox Community. I received one response asking if the problem still happened in ‘Troubleshooting Mode’. My response 'yes' it does but I have not had any other reply. Hence, I am stuck. Nothing has worked which I find very frustrating. I have used Firefox for many years now but if I cannot resolve this matter I will have to select a different browser which I don’t really want to do.

I'm installing a Docker service set onto a new Ubuntu system, that has Firefox installed by default. One of the services is a GUI application.

However, when opening Firefox for the first time, a dialog shows up that I would like to disable (attached).

How can I disable this?

I'm running Firefox using: "/usr/bin/firefox --kiosk http://localhost"

I've already followed a lot of the suggestions in here: https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs (and verified they are indeed set after installing my own "user.js" file), but I cannot find an about:config preference that disables what I'm still seeing.

Any help or ideas?

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.

Update 123.0 deleted all my firefox data from logins.json. backup files are corrupted or have no data. No support article suggestions have worked. The .json files indicate that there is data, but appears blank in notepad, and wont load in json reader in firefox

I've been trying to reply to moderator "Phil" who requested information regarding Firefox crashing while on Youtube. When I press "Post reply" all I get is an error message:

An Error Occurred

Oh, no! It looks like an unexpected error occurred. We've already notified the site administrators. Please try again now, or in a few minutes.

It's important "Phil" gets my message as others may be affected my possible Youtube shenanigans. If possible, can you forward this message to "Phil": Unfortunately there are only two reports generated during the problems with Youtube:

The problem caused my system to stop responding forcing me to power cycle to clear my PC, so no reports could be generated. Hopefully these two will show what the problem is. In the meantime, can you check the reply system to make certain it's working properly?

Greetings. so I have been using this type of browser since netscape vs ie. enjoy and use firefox daily, when i can. there seems to be a weird process of constantly changing the software, and not allowing reliability. I can set for no updates, or only if i allow it, but firefox ignores me and updates anyway and then displays a new front page describing the mischief the coders have been up to. couple weeks ago, you broke it. dead. like a brick. switched to brave, there were a couple updates, you undid whatever you broke, fine. then a day or two ago, broke it again. not really a fun game. once i am able to move bookmarks over to brave, why do firefox? it takes forever to start, presumably while it sends all my browsing history and downloads to be examined for commercial potential. I can give fire fox a 2 or 3 minute headstart, hit brave, in 10 seconds i can use it, firefox still busy with industrial spying, or something. eating a sandwich? who knows. if there is any way to tell the coders to create a do not change, leave my damn browser alone because it works button, that would be nice. otherwise, its just a weird game for someone i guess, but i dont have time to play.....

Hi everyone

I've experienced a problem with Firefox on the Metacritic-Website. As you can see on the attached picture on the left, it's not possible to set a filter for "release date". There's no problem when I use Chrome (see picture on the right). The problem still persists when I start Firefox in safe-mode, so it's not related to an extension. I could replicate the problem on another system as well. Firefox on iOS has no problem setting the filter however. Do you know what the problem could be?

Thanks, Phil

Hello, so I have been putting my custom links onto the 'top sites' start page in Firefox, by editing the icons and putting the URL, etc. It is a great 'speed dial' type feature I love. One thing has me tearing my hair out after trying all ways to try and fix this to appear to my liking, is the 'custom icon' from the website not showing in the sites I want to 'speed dial' Facebook and YT show up fine, but random sites I want on the page don't do this. I don't care why this is anymore, please don't give lengthily fixes. It's just silly you need a working URL with an icon at the end of it to display this properly. It did make me very mad, can you tell, even madder when I saw it done as it should be in OPERA browser, on their 'top sites', or 'speed dial' customizable home page they have the sensible option there to pick your own icon, you can put in a folder on your desktop if you like, no working URL needed! start a collection of what icons you want to see on your own start page. Can you please implement this 'common sense' modification as soon as possible, it will take only minutes of code writing i'm sure. I do not want to, but I will go to Opera as my main browser for this common sense functionality, good luck and thank you.

Every time I browse incognito mode and download files (pdf mostly), then I exit the browser and my files disappear from the Downloads folder in Windows 11. It has been like this for a long time now. I have to remember to cut and paste them to another folder before shutting the browser down, but when I forget it's annoying. Can this be fixed?

When I'm viewing a PDF from within Firefox and try to print the page, it shows a smaller version between 1/2-3/4 of the size of the paper. I have "fit to page selected" and this doesn't change it. I try a larger than 100% scale and this doesn't change it either.

However when I download the pdf and pull it up using Acrobat it allows me to print full page, fit to page, scale, etc no problem.

Initially I thought it was my printer, but I removed and reinstalled the drivers for the printer and I don't have this issue with any other program except for printing from Firefox. It's almost like the Firefox browser has too small of a page default set so that it's fitting to a page, but the page is smaller than 8.5x11 printer paper.

How do I fix this?

I need to run speech recognition in Firefox (OS solutions are not suitable in my case), but I can't get it to work. I've tried following these instructions in Nightly, Dev and regular version, but they all end with a network error. I also asked my friends to check and they had the same thing happen. Do I need to follow the steps to run offline or is the problem much deeper?

Hi,

Since about two days ago firefox on both my PC and laptop has been trying to connect to a random website called ponf.linkedin.com that I have no idea where it came out of.

I have no clue why this was but I reset both browsers on both devices + reinstalled windows 11 on my main PC and it only continues happening on my PC now, i've managed to replicate the behaviour by resetting the browser and everytime that happens firefox attempts to connect to this website even though bitdefender blocks it and nothing comes up, no popup or anything as if its just in the shadows.

Does anyone have any idea why this would be and what I should do? any help is appreciated thanks.

My Firefox browser is broken, I can open Firefox but I can not do anything it will not respond, clicking anywhere prompts a "Firefox is not responding" error message, I was able to "refresh" Firefox once with zero results, I have tried uninstalling Firefox yet it will not uninstall the uninstallation window comes up yet no matter how long it sits open nothing happens, I have tried reinstalling Firefox with no results, the installation freezes just before completing and says "Firefox could not be installed". I have been using Firefox as my primary browser for a long time but I am unable to use it in any way now. All other browsers are working fine no issues but I do prefer Firefox and would like to continue to do so. What do you suggest?
