Diễn đàn hỗ trợ Firefox

I noticed that on Facebook there is not shown data and time on every post. Some posts show this info, the other don't. I cleared cookies, deleted Facebook from history but it didn't help. On Chrome everything is showing normally. I put Firefox in solving problems mode, with add-ons off, it didn't help too. Any solutions?

when playing videos, firefox makes the videos much darker and higher contrast than the original videos, as well as maxing out the cpu on my laptop when playing video, started a day ago or so.

I have a 2020 Mac Mini with Ventura 13.2.1 on it. I have four virtual desktops which are part of the OS. I place various apps on the others like stocks and weather etc. to diminish clutter on screen. Firefox shows up on all 4 of them. I want it on only one desktop. Safari works on only one and doesn't show in the other 3 desktops. I have searched the net but haven't found anything that speaks to this in particular. Thanks for any help with this and I hope it's just a simple setting. Regards, Jim Stephens

I installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome.

When I type about.config in the address bar, I just see search results for it, instead of going to the config page. I tried enabling a separate search bar in settings, and also turned off all suggestions, but that did not help. I still see the spyglass search icon on the address bar. How do I get past it?

I have seen multiple copies of this question, some unanswered, some with the same "answer". All the questions are closed so I cannot reply to them. The "answer" does not work.

I have the "Show tabs from other devices" sidebar. I also can access from "Open application menu" > email address > list of synced tabs. Both methods show me the device name and all of my synced tabs. Neither method has an "open all tabs" option. If I right click my device name nothing happens. If I right click a tab, it opens that one tab. I don't know how many tabs I have on my Android. I have enough tabs that it only shows the infinity symbol instead of the number. It has shown the infinity symbol for a long time and I've opened many more tabs since. It could be hundreds or even thousands of tabs. I have 224 tabs on my laptop. I want to open all 224 laptop tabs plus all however many Android tabs on my laptop at the same time. I'm aware this will cause significant lag on my laptop. I'm not looking for a solution for that or people telling me not to do that. I want to know how to open all of my synced tabs at once on my laptop, without having to click through one by one.

Edition Windows 11 Home Version 22H2 Installed on ‎2022-‎09-‎21 OS build 22621.1702 Experience Windows Feature Experience Pack 1000.22641.1000.0 "You're up to date Last checked: Today, 17:15" (Just clicked "Check for updates")

Firefox 113.0.1 (64-bit) "Firefox is up to date"

Hello all,

I am having problems with video playback on some websites (see screenshot attached). The problem is that the video options start to "multiply" - for example, when I start the video there is (as is normal) one 'Speed' and one 'Quality' button, but then every second these buttons start to multiply. This happens only on some websites - for example, it does not happen with normal videos on YouTube, although it happens on YouTube Shorts sometimes.

This is my first question on the Mozilla Support page, I thank you in advance for your help and I hope I follow the community guidelines. Please feel free to leave any suggestions or feedback concerning how I should proceed for asking for help in the future.

I just installed Win 11 with a fresh Firefox install (113.0 / 64-bit). I use a single video screen.

When I double-click on the FF icon, no Firefox browser window appears. However, in task manager, I can see that Firefox has opened and using a lot of memory.

I also put the FF icon in my "Pin to Taskbar" area. After I start FF, normally I would see the pinned icon highlighted (program open), but the taskbar FF icon does not show FF as active.

What have I destroyed this time?

I'm trying to use multi-account containers to use twitter and other sites from accounts unique to the container.

For twitter, if I select a container, a new tab opens with the twitter login page in that container. If I try to login, another tab opens in that container, with the login page. So, I can never log in.

Is there a solution?

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

Lately when opening something in full screen it shows the background as sort of a frame around it. The dark blue at the top is the header background colour I use. It's really annoying. I can't tell if it happened in a recent update as those happen automatically. But it's just been the past few days. I use 113.0 (64) right now. I'm sending a screenshot of how it looks.

I've just had to completely reinstall windows without being able to backup my files (I couldn't launch my computer in order to actually back them up) meaning I've lost my recovery codes. I thought this would be fine as I could just sign back into firefox on this new install of Windows but as it turns out I must've forgotten to put my sign in information into my password manager. Again, I thought this would be okay as I still have access to the email I used to sign up to my firefox sync but I got the message saying I'd lose my data which isn't fine and now I'm at a bit of a loss. I've had to use a spare email to make an account and ask here but I'd really love my old account back. Is there any way at all I can get back into my account without losing my bookmarks and passwords? If not, how much information would I end up actually losing? I'm slightly unclear on that part. Do I lose absolutely everything? I'm a bit stressed about all of this ontop of losing all of my old computer files so I'm sorry if this is a commonly asked question but I was struggling to find anything that helped me D:

Any advice at all would be really appreciated thank you so much!!

i cant move the tabs around in the task bar. my firefox version is up to date, but yesterday-ish my laptop forcibly updated itself. its still on windows ten, but thats the only thing i can think of other than installing a kidpix four emulator that may have caused the problem

Hi, I disabled several options in about:config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and automatically navigated to it. Also, when there was a previously open page, and I open any bookmark (tags), the selected page opens in a new window, I want it. Please help me.

Currently I'm using the css from this thread https://support.mozilla.org/en-US/questions/1341968 Now with firefox 113, this no longer works, I'm hoping someone can help me with this.

Firefox opens with a new tab containing 8 links per row. However, all subsequent new tabs have only 6 links per row. They used to always have 8 links per row. Why? A bug or a configuration change? I have made no changes.
