Diễn đàn hỗ trợ Firefox

I'm trying to get my wife's firefox browsers synced - mainly her laptop and phone. I've got the phone signed in and working fine, but on her laptop there's no option to sign in and the sync option is missing from the settings menu?

It seems to be profile related as if I create a new blank profile the option is there - but if I copy all the data from her original profile the option goes missing again. Short of manually copying all her data over, I'm a bit stuck for what to do next - any ideas?

I've tried disabling any addons, restarting in troubleshooting mode etc. I've also looked at all the other solutions I can find from here (mostly related to group policies, there's nothing enabled on this) and everything seems as it should be.

I haven't tried reinstalling, but it seems like this is a profile issue rather than an installation issue?

It's a Win 11 laptop (upgraded from W10 if that makes a difference), FF version is 135.0 64 bit.

Thanks!

I have downloaded the mozilla extension " screen recorder". After giving all permissions , the logo of this extension is not showing on my screen .SO, I am not able to use this extension facility. Please solve it. And also I have been blocked for accessing this extension owner' s website. THANK YOU. OM PRAKASH GUPTA

Firefox will not start on my PC, so in the process of troubleshooting, I reset my password to get into this Mozilla support site. I saw the notice about losing sync data, so I followed the instructions. I changed the password, then went to my iPhone, where Firefox is running. However, when I tried to create the backup, it would not take the new password. I presume that since it was running on the old password (which I do not remember), which is the password required for the backup. Next, I logged out of Firefox on my iPhone and logged back in with the updated password. Now my data seems to be gone.

I have two other devices running Firefox, iPad and another PC. I need to know how to create a backup that I can restore my sync data.

Changed behavior of autofill is a small thing. A few weeks ago, I could enter the first few letters of a site and then down arrow to choose one from the list. Down arrow no longer works here.

A significantly bigger issue allowing a website to open a window or tab or popup. There used to be two buttons when this happens, allow and always allow. Always allow is no longer a choice. I have to click allow every single time I go to that web site. Since two of those sites are the enrollment and learning management systems where I work, I'm doing that 20 times a day. If disappearing the always allow button was a design decision, it was a bad one.

I am trying to use my recovery key, but the form does not accept the letter Ø. The letter Ø is nok defekt at my computer. What could be the problem, and how do I fix it?

On my windows PC, I am unable to view Ring Camera live-view due to "error missing required codec". Does my Firefox have the required HEVC codec to view Ring Camera videos?

The logo in the top left-hand corner of my website's landing page does not display using Firefox but is displayed properly using every other desktop browser. Using Firefox, just my name is displayed in place of the logo. Chrome for Android has the same problem but Firefox for Android displays OK. On my iPad both Chrome and Firefox display properly. What are the reasons for this? Is there some upper limit for the dimensions of the logo (mine is oblong in shape)? Do I have some settings that don't suit certain browsers? My site was built using Wordpress/Elementor/OceanWP. Many thanks in advance for an answer!

I'm not sure I have the right topic as I didn't see what I will try to say. The problem is when I send an email (googlemail), I cannot insert a photo/picture in the email. The only thing I can do is attach which I do but want it inserted too. This only started happening about 2 weeks ago. It is now to the point where I have to use another browser to get it to work as it should. Any ideas why?

NOTE - I am using Firefox on my PC which is working fine. Issue is with my laptop Firefox.

Firefox was working fine, on my laptop and PC, until about 3 days ago. Started getting Tried to download various versions of Firefox. I am using Firefox on my PC with the same exact settings, network, Win 11 and Antivirus as my laptop. Firefox, version 128.6.0esr (64-bit) works fine on my PC, but does NOT on my laptop. I uninstalled FF and reinstalled it, changes Firewall to Windows on the laptop from my AV, NOTHING. Driving me crazy. HELP please.

When I put my laptop to sleep, websites I am logged into are often logged out when I return. Note that I don't close Firefox. The tabs generally reopen but require login again. Windows 11, Firefox 137.0.1

For example, I put my laptop to sleep for lunch. When I returned, tabs were there, but I was logged out of gmail, Discord, and a website I was logged into.

This seems to happen more frequently recently, but not every time, as far as I know. But this is a relatively new problem, possibly related to a new laptop. Occasionally I get a message that there is trouble restoring my session.

Audio doesn't work with Firefox. This appears to be ONLY a Firefox problem. Headphones work with Edge. Computer speakers work. In Windows settings, testing audio works. But when I attempt to listen to something in Firefox, there is no sound at all.

Why does Mozilla say insane things like put your passwords in a safe place? Mozilla just today made mine disappear. Can the morons at Mozilla understand the problems this has caused? I am through with sitting before this machine trying to get thru this B S ! Want to help now? Give me my G D password manager back... Safe... what a D joke.

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.
