Firefox Community Forum

Firefox is deleting my website exception list whether I have "Delete cookies and site data when Firefox is closed." checked or not. It is the same with the exceptions list for logins.

I like to split windows so I can have running YouTube videos on the left half of the screen and browsing the web on the right. If I open another site on the right side of the screen that has multimedia (ESPN, CNN, IMDB), the video freezes on the YouTube window but audio continues to play without issue.

I have done the following troubleshooting steps:

• Hardware acceleration turned off/on
• cleared cookies/cache
• A few About:config fixes

Videos don't have a problem running if I open YouTube with Chrome and continue to use Firefox for surfing.

i9-12900hk 64GB RAM 2TB m.2 SSD (lots of free space)

When I google search while logged into my google account the results are missing the favicons.

However when I log out of my google account or go into private mode everything works as expected.

Pls help

I can't see the SYNC option in Settings so I...

Use about:config to change identity.fxaccounts.enabled = true I can now see 'Sync' in Settings When I go to "Sign into Sync", after I enter my password, it hangs for 10 seconds, then says Working, then always just hangs there forever. If I login to Mozilla using a different tab, it signs in ok.

I have tried this after successfully changing the password, and after restarting firefox.

I am using the latest Firefox version.

Any suggestions gratefully accepted.

How can I block the dropdown video miniplayer in Firefox 120.0.1 on Windows 11? It doesn't happen in MS Edge.

I've already set the following with no results:

media.autoplay.default = 5 media.autoplay.blocking_policy = 2 media.autoplay.allow-extension-background-pages = false media.autoplay.block-event.enabled = true media.block-autoplay-until-in-foreground = false

Is there a setting that I've missed? Can the miniplayer somehow be blocked using userContent.css? Can the miniplayer be totally removed from Firefox?

I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

tell me how to undo "troubleshoot mode", read the "help" article, do not understand.

tell me how to undo the "More from Mozilla" in about:preferences. I have NO idea.

I try, but I am usually confused by these help articles.

I had 2 windows open, closed one, lost all of my tabs. Restore didn't work. I tried to restore by renaming session-store-backups folder files. doesn't work. There is a file called upgrade.jsonlz4 from November, maybe that could be used to restore tabs somehow?

I have dealt with this message when searching the web... after a google product search etc., the results populate- then I click on all the top results and I get nothing but this message and the sites will not open:

Secure Connection Failed An error occurred during a connection to www.googleadservices.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

I noticed it's with most "Sponsored" results. Incredibly frustrating.

Please help!

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

Since approximately July 2023, Firefox gives me a beachball and pauses for about 10 seconds whenever I change between it and another app, or between one Firefox window and another. The same behavior does not occur with other browsers, likewise whether my connection is WiFi or wired.

I have No Proxy set in Network Settings. I am running a 2021 M1 Max Macbook Pro on Ventura 13.5.2.

I would appreciate any advice on how to troubleshoot and fix. Thanks.

I found how to backup and transfer my normal bookmarks, however I really need to backup and transfer my bookmark toolbar, specifically on the Mac version. I can only find the PC version instructions and they don't seem to translate between OS's.

learning windows 10 - closed a window retrieved from the taskbar - can i get it back with its 49 tabs? i can get an active window showing the recent files i was working with, and i can open ONE of the tabs ("one document") - went too fast i guess. thanks for any response. hope i did the "share data" for you properly.

I think it has to do with cookies, but I can't figure out what to fix. I have my tracking privacy set to strict. Twitch has permission to use my cookies and site data (Settings -> Privacy and Security -> Cookies and Site Data -> Manage Exceptions). All of the other websites that I have granted that permission to have no problem remembering my device, but Twitch does. I looked at this post already and my account was already set to these settings. How do I make Twitch remember by device? It's annoying to have to go to my email and use a one-time passcode every time I log in.

For over a week now I am receiving a popup from 'The Spruce' with the popup header being Mozilla Firefox (see Spruce.jpg). The popup has a facility to disable notifications from www.thespruce.com and I have selected this many times yet the popups keep coming several times a day. (see Spruce2.jpg). I have also visited the Spruce website and there is no unsubscribe link. I didn't subscribe in the first place and had never heard of The Spruce before this. Why is Firefox facilitating this spam that won't be disabled?

Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4
