Diễn đàn hỗ trợ Firefox

Ever since I installed Firefox 123.0, when I execute a search on Yahoo.com, Firefox automatically opens up a new window or tab (depending upon how you have it set up in settings) when it didn't before. When I try this with Firefox using Google.com to search, it does NOT open up a new window/tab. But when I try it with Yahoo.com when using Google Chrome, it does NOT open up a new tab. So it would appear that the behavior is being caused by something in Firefox.

I tried making various changes in settings and Firefox about:config that were recommended in previous questions here, but they did not alter the behavior. I would like the behavior to return to simply performing the search within the same window (I can always scroll back to get the original page). Can anyone help?

Whenever I try to play videos on Firefox, the elements don't load right and no video will begin. On Youtube, this is usually either a blank page with no video element, or I get an error stating that the video can't be played. On Twitch, I get the streamer's default 'not streaming' message, even if they are live, and VODs don't work. I have several extensions to protect privacy and block ads, but even if they are all turned off I still have this problem. I've also tried turning my VPN off and on, and setting it to various different locations. Nothing works. I can watch videos on another browser without issue. My extensions: Facebook Container Privacy Badger Flash Block Plus SponsorBlock Bypass Paywalls Outline AdNauseum

I'm getting the error message "No video with supported format and MIME type found" with mp3 files at https://www.gatherthepeople.org/test/styled-7/page-3/ when using Firefox 123.0 on my M1 (ARM) iMac running OS 14.3.1; when using Firefox 123.0 on my M1 (ARM) MacBook Air running OS 14.3.1; when using Firefox 123.0 on Win 11;and when using Firefox 115.8 on my Intel MacBook Pro running OS 10.14.6.

The same mp3 files (https://www.gatherthepeople.org/test/styled-7/page-3) play without any problem with Chrome and Safari on the Mac and with Edge on Win 11 .

Thanks

After some time of idle, i.e. leave the computer for some time, say over night. No suspend or hibernate. Back to the computer next morning, unlock. Then Firefox appears frozen/hang, can't switch tab (clicking tab has no response, but not really frozen, sometimes responses after dozens of seconds of lag), page also has no response. Then after around half to 2 minutes, everything back to normal.

During the "hang", CPU load is load, no memory stress (swapping/paging).

Environment:

Firefox 123.0 (64-bit), (actually it bothered me for years)

Linux 6.6.15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.6.15-2 (2024-02-04) x86_64 GNU/Linux

``` lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux trixie/sid Release: n/a Codename: trixie ``` Not related to particular Linux and/or kernel version.

CPU: Intel or AMD, not related. RAM: 64GB/96GB, free memory more than enough.

I will gather more detailed info later.

Hi. I keep several Firefox tabs open and active on my laptop. Inevitably, Firefox slows down after a week or several weeks and would benefit from a Quit / Restart. But then (I think) I would lose my tabs, which would mean a trip to the library to login and get them back. If I do nothing, a superslow Firefox will usually mean my laptop eventually restarts on its own. Then when I open Firefox I see a "Restore Session" option, which brings everything back (I think I see Restore Session because the computer did its own shutdown). So, this does work, but I have a slow computer until the laptop does its own restart. I am wondering if I can initiate my own Firefox Quit / Restart which will give me the "Restore Session" option. Thanks!

Good Evening. I can't enable or manage shortcuts on the home page. I put a link in the boxes and it doesn't keep it, it doesn't save it.

Shortcuts

Websites from bookmarks or history

Thanks

Starting recently the firefox popups for website notifications are stealing focus and disturbing my workflow. I'm using i3 window manager and normally popups would have some id or class that can be used to latch on and prevent the focus stealing but the windows created now do not have any such marker.

made this post on reddit too https://www.reddit.com/r/firefox/comments/1bhztyg/non_full_screen_video_player_bug_exclusive_to/ but notice how theres this weird color bar right above the video player, this happens whenever i play anything on hulu.com. any solutions? thanks for any and all responses in advance :)

Amazon search has disappeared from browser and not included in list of search engines. I want amazon.uk not U.S. and I do not know where about:config is.

There is this new pop up coming on latest firefox version 123 about opening favorite link on firefox, I want to get rid of it programmatically using java, which argument or preference should I use ?

Everytime I try to open a tab on my Firefox window, it loads for a second before a blank screen saying that my tab has crashed. The only times I can open a new tab is on a private window.

For years had bookmarks in folders showing on Bookmark Toolbar. Today they are all gone. Still in my Bookmarks on the drop down Menu, but not appearing on the Toolbar. Please help. Can't seem to drop and drag them there. Also, the Bookmarks Toolbar keeps disappearing every time I go to look at a new tab.

Just recently been getting yahoo search engine results to open in new tabs rather than the same tab. I have searched for other users that have the same problem and have done the tracking protection thing and deleted cookies, but nothing helped. Also tried Troubleshooting Mode and it still persists. Any other ideas that may help? I'd appreciate it.

When you click on the player in YouTube, it lights up, how to turn off the backlight. If I click on the play button, the button is highlighted and I can’t press the spacebar to press stop or play

Windows Updates (KB5035845) and 10.0.19041.4163

After these latest updates, EVERY, Firefox browser (derivatives included, i.e. LibreWolf, etc...) are opening VERY slowly. Its almost like the browser is freezing while opening for around 10 - 20 sec, then opening. It used to open within a second or two. If I uninstall the updates the problem goes away, BUT, windows re-installs them automatically. After it is up and running its ok. The problem seems to be on startup only.

Hello, Firefox keeps crashing every 1 or 2 minutes. thats a new Endeavouros installation and firefox was pre-installed. system is fully updated.

would you please assist troubleshooting the issue

I've tried EVERYTHING I can think of to fix this issue. When 'trying' to open a YouTube video in Firefox, I'm 'informed' that I'm offline - try reconnecting (or something like that). I'm NOT offline. Three other browsers have NO problem opening these YouTube videos; it's only Firefox. Can someone PLEASE come up with a REAL resolve to this issue? I don't want to give up on Firefox and go back to Chrome. But this issue is VERY annoying. Thanks to anyone who can provide constructive resolution(s). AL R.
