Firefox Community Forum

Hi why have firefox started to close tabs when browser beeing closed? Allready checked the usual sugggestions like open previous, private mode etc. Assuming this relates to an update because have same issue on several computers ( same account)

"Access Denied" when accessing homedepot.com and lowes.com using microsoft edge or firefox within windows 7

This has started a few days ago. I'm running Firefox Desktop on Windows 11. Browsing is perfectly normal, until I try to watch a video in full screen mode. It plays normally for a few seconds and then my whole system freezes, with no response to any action except for hard reset. This has never happened to me before, and all other browsers I try do not demonstrate the same problem. Is there any solution other than changing browser permanently?

Добрый день. Проблема наблюдается примерно около полугода. В браузере открыто несколько вкладок, не закрываются (новости, ВК, поиск, различные статьи и тд.). Происходит следующее: читаю активную вкладку, строго через определенное время, без каких-либо действий с моей стороны, активная вкладка меняется, т.е. открыты вкладки 1-5, активная 2, через 10 мин (до переустановки мозиллы всегда одно время) активной становится 4, к примеру. Раньше фокус перемещался на вкладку поиска Yandex, если закрыть вкладку с Яндексом проблема уходила! Я удалил браузер Yandex и все что было от него (автозагрузку, планировщик заданий), переустановил Firefox. Какое-то время все работает, но потом начинается снова, тут время переключения меняется. В последний раз (после удаления Яндекса) фокус стал переключаться на mail.ru, значит яндекс тут не при чем. Если закрыть Mail проблемы нет, если открыть страницу снова, то примерно через 1 мин. открывается mail.ru. Доп. информация Windows 11, плагинов и расширений в мозилле нет, пробовал работать в безопасном режиме браузера - не помогает, перезагрузка не помогает, помогает только закрытие "маркированных" страниц, проверял на вирусы NOD32, cureIT в безопасном режиме работы ОС, вирусов нет. Очень прошу помочь с решением!

I have upgraded my PC from Windows 10 to Windows 11 and my Firefox bookmarks have disappeared. I understand that Firefox keeps a copy of my bookmarks which appear each time I start Firefox, so how can I make them appear again automatically when I open Firefox?

Recently, whenever I put a video in PiP, the whole browser freezes. I'm not sure what causes it. The PiP player itself is playing and working fine, it's the browser as a whole that freezes completely. I can play/pause and even pop it back to its tab, but when I do, the browser is inaccessible to me because it freezes, despite the video still playing normally. I can only terminate the browser with Task Manager, otherwise the video will continue playing and the Firefox process goes on the background.

I have tried Googling for a way to fix it, but nothing seems to work. Some of the recommendations were to turn Hardware Acceleration off, allow autoplay, upgrade GPU drivers, and test in Troubleshoot Mode. I have autoplay completely off (including in about:config) and gave an exception to YouTube. I don't think this is the problem though, because I've had it set up this way for a long time, and the browser freezing only started happening recently. I have had Hardware Acceleration off for a while too, so it's not because of that. My GPU drivers are up-to-date (Nvidia). The browser still freezes in Troubleshoot Mode.

The problem is not limited to YouTube. Wherever I can pop the player off with PiP, it will freeze the whole browser (like Twitch or any other site with video player capabilities). I tried playing a video in a different browser and it worked just fine with no freezing, it only happens in Firefox.

I noticed that the common issue people report is the PiP player itself freezing, but my case is the exact opposite. The PiP plays fine while the rest of the browser freezes. I really like this feature and don't want to turn it off if possible. I like to pop the video out and watch it play while I scroll around on my desktop.

I use Stockhouse.com as a homepage and when I opened my computer this a.m. the site came up and it asked me to sign in which it normally does these days and I click on sign in and it shows my email and password and I click again and I'm signed in. This morning it asked me to provide my email address and password i.e. fill in the blanks. It has not done that for at least 15 - 20 years. Not remembering offhand what my password was I clicked on the 3 line application tab in the top right hand of my screen and brought up the list which includes "Passwords". I clicked on the password file and it is blank. It has never been blank before -- did Mozilla/Firefox make a change that would make my password file disappear?

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to na.nikken.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

Probably nothing, since it’s likely there’s a problem with the site itself.

The site is ok when I open on another window and even on Google which I don't like.

All of a sudden (after a recent update I suppose) every time I start to type anything in the "search" in the middle of my "home" screen, the curser jumps to the address space in the toolbar. I hate that! I want to continue to use search in the middle of the screen as I have for years since I started using browsers. I've tried looking at the setting for "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" and it is set to "false" as was recommended in another post some years ago. What do I have to do to revert back to the way it was before this change was forced on me?

When trying to play video from https://www.camelbackresort.com/resort-information/live-cameras, I get the following message:

The media playback was aborted due to a corruption problem or because the media used features your browser did not support.

I'm running Firefox 148 in MacOS Ventura (current version)

I've tried the following:

Turning off Privacy Badger Turning off the default add blocker Starting the program in Safe Mode Refreshing the browser Turning off DRM Controlled Content Turning off Use recommended performance settings Deleting cookies related to the website Clearing cache and temporary files

None of the above had any effect. I was able to play these streams in earlier versions.

The streams will play in Chrome but not in Safari so this may be the result of a change in the website that was not tested outside of Chrome.

Any other suggestions would be helpful.

I just upgraded my Dell desktop computer -- Win 11 and some other hardware tweaks. Everything is fine -- but an old problem that was resolved some time ago in this forum has reemerged. My mouse wheel does not scroll properly at all with Google Calendar. I recall a simple solution on this forum that worked perfectly a few years ago when I originally set up the computer. It has apparently been removed, and I can not find anything to resolve the matter. Does anyone recall the secret formula? Is it hidden away somewhere? The scrolling is so convenient, and the instinct is hard to break.

After using firefox for most of my life i am disappointed with the current service i am receiving. I have recently purchased a new laptop with windows 11 installed & no matter how many times i try my passwords are not being synced. I have imported them from my last device but the only password that is showing is the mozilla firefox account. Please help as i am constantly having to change my passwords as the previous ones are not shown. Thanks

I sent another help request on this subject but that too seems to have gone AWOL so I am trying again.

My passwords are being randomly wiped from my PC yet again but this time, although they are still on my Google Pixel 7 phone, Sync is not working for passwords. Strangely however, tabs are being synced.

I have tried every suggestion that I have found but syncing is just not happening.

To re-cap:- Passwords are not being synced from phone to PC Tabs are being synced between phone and PC.

Any suggestions?

Firefox 146.0.1 (aarch64) macOS 26.2 (25C56) on M2 Pro

Hello.

I'm dealing with a strange issue that began with Firefox 146.0 and continues with 146.0.1. I previously blocked categories I do not care about such as Parenting, Cooking, and others. When doing so, for some reason some of my followed topics including Sports, NFL and NHL no longer appear along with the rest of the topics I've followed. (Please notice only followed sports-related topics disappeared...)

Checking the settings for Firefox Home shows no blocked topics (even those I have explicitly blocked), and checking what I can think to think via about:config shows me nothing I can edit to get my desired topics back.

So, I'm not sure what to edit to get my missing topics back. If they were blocked because of some bug, i cannot see blocked topics in the Firefox Home settings, so I cannot unblock them if that's what would need to be done. Has anyone else experienced this? If so, were you able to resolve it or are you aware of some BugZilla or GitHub issue I can watch for this one?

Any help will be certainly be appreciated. Thank you in advance.

Some videos work perfectly fine, however for some videos audio lags behind the video. The same video file perfectly works in Chromium as a control test. Example file is MP4, inside was initially h264 video with AAC audio, for test I re-encoded video to be svt-AV1 with AAC / flac as well - no difference, audio still lags behind. Local players (mpv) and Chromium works perfectly. No plugins which can affect it - for testing disabled them all. I really try hard to like Firefox but this thing is a real bummer. Any ideas what can be causing? P.S. I tested both firefox compiled from source and binary package provided by my distro. Linux system if that matters.
