Diễn đàn hỗ trợ Firefox

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

Bought a new windows 11 ASUS laptop. Trying to install an HTML bookmark file from older windows 10 ASUS laptop. When I execute the HTML file import on my new ASUS windows 11 laptop, nothing happens. Even found and removed the "block protection" in the HTML file.

Why am I unable to import a firefox bookmark HTML file?

Thanks for any solutions anyone can provide.

Clicking the mousewheel still works, but scrolling doesn't work. This behavior occurs on tab bar as well.

Using option "Restart with addon disabled" from about:profiles can make the mousewheel scrolling work, but manually disabled all addon and restart just won't solve it.

There's a gap between tabs and the window controls in the top right. You can use this space to grab the window when you have a full set of tabs. This functionality breaks when I move the window to my third monitor.

Hi guys! Currently I'm working on a project which renders video with webGL. The result works on all browsers as expected but not with Firefox vers 109 for Apple Silicon devices (m1, m2) - the video animation is just lagging,it takes cpu usage up to 160% and the video itself is stretched. Comparing to that Chrome takes 22%, Safari 14% of cpu usage. It's just regarding to this devices, it works fine on Microsoft so I think it's a browser bug regarding to osx verision. Could someone pls help me with that or have a look over?

I'm on FF Beta v105.0b6, and a recent upgrade (I'm guessing from 104 to 105) has caused popup windows to be ghosted when saving files, leaving only the file selector field visible and floating above the main window, often indistinguishable from the text below it. I've been able to work around this by temporarily jumping to another screen or window and then back to find the complete popup window magically revealed.

I've attached two clips from windows a see after clicking Download link on the https://www.mozilla.org/en-US/firefox/new/ page. This ghost behavior also happens on pages where I right-click context to "save as" or click download link for TXT, PDF, PKG or other types of files.

This doesn't seem to be a popup blocking issue, since my FF is not configured to block these specific sites and the popup is minimally visible. Also, the temporary workaround of simply switching my view away and back points more to a page rendering issue.

I'd appreciate any ideas on resolving or preventing this behavior. If these clues point to a bug, I hope they help resolve the issue.

Thanks for any suggestions!

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

The problem is as follows:

Every time I load some multilagual web page (Aliexpress, prestashop.com fox example) Mozilla loads the page in different language. After I change the language and load a new page from the site, the language is changed again to a random one. Every time I click a button or link, the language is changed.

Cleared cache, and cookies and everithing multiple times. After 3-4 days it does the same thing. Tried fresh install - after a while starts to do the same thing. Installed Firefox Developer Edition - after 6 months starts to do the same thing. Installed Waterfox on different PC - same as Firefox Developer - after 6 months starts to do the same thing.

Does anyone have the same problem? Why is it happening? Is it only me?

I have been seaching for the solution for the whole day, and i found the closest one. It Does remove tabs, windows buttoms, but the background bar still remains, and i dont need it this way. So thats the code i used to make it >>>>>

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

1. main-window:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

} /* This makes the bar shorter vertically but removes the 3 window buttons */

1. main-window #TabsToolbar {

 visibility: collapse !important;

} /* For full screen mode */

1. TabsToolbar[inFullscreen]{

 display: none !important; 

}

On the screenshot you can see what remains on tabs' bar place I need my browser to end just above the URL string, so there wont be empty space in the top of the monitor. Can you help me find solution for this problem, please?

MacOS FF dev edition 102: I have a folder in my bookmarks toolbar, and I frequently open all of them in tabs. But that option is missing from the context menu on the folder. It is there at the bottom of the folder if I click to open the folder, but this is silly. There is an "open all bookmarks" context menu option on the folder, but that opens all the bookmarks in the toolbar, not in that one folder. why is this?

I developed a web app that checks the existing session login for each new page. So, after logging in the first time, the user is shown a dashboard with a list of functions they can access (My Account, etc). When an item is clicked and the application calls the function, it first checks for the existence of login session. If it's not there, then the user is forced back to login screen. However Firefox is deleting the session at some point so when the session is checked for the new function, the user is forced to login again. Chrome, Safari, Edge do not and are fine.

Enhanced tracking is turned off for the site and is shown as an exception. What is happening and how can prevent it?

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Some videos on YouTube wil not run - shows just that circling arrow !

I'm running a fully updated Windows 10 - F5 don't cure the problem Restart PV, router or modem don't Reset FireFox work but only just after reset - if I try show the same vidoe again - same problem is back ! I have tried running is safe mode - no help ! I've tried to shut down AddBlocker - no help !

It's NOT all videos and not all videos from the same creator !

The problem started 4-5 days ago and is worsening !

What is there to do ?

Firefox prioritizes IPv6 (even on a network with internet-accessible fd00:: address, which contradicts my currently set up prefix policies) over IPv4. Now the problem is that my IPv6 address is a tunnelbroker.net one, and while I still want to be able to access the IPv6 internet, I don't want a tunneled connection to be my default. And I don't want to disable IPv6 completely. Is there a way to force Firefox to prioritize IPv4 over IPv6?

Note: the first time when connecting to a website, the browser connects via IPv4 (like the prefix policies are supposed to work), but then it remembers that the website is accessible via IPv6, saves it into the content-prefs.sqlite file (removing the said file makes the connection fall back to IPv4 first again) and connects via IPv6 again. Is there a way to make Firefox NOT remember that in content-prefs.sqlite and still connect abiding the prefix policies?

Using Firefox Dev Edition 103.0b9 on Windows 11 x64

1. When I create a sign on for a new web site Firefox is no longer saving and auto filling the logon credentials. 2. Now when I load a website logon screen it is not always auto filling the stored credentials. Instead of auto filling now I must click on a displayed use rid to get the use rid field filled. I then have to click on the password credential to get the password auto filled.

Hi,

Its about time you looked at your Mic cam Cam settings

I'm getting older, they should be set as on as Default, and switched to off if required

This is a massive issue to a great part of the community I don't use Firefox as I used to, as so many of my clients are also moving away, ( Gone to different platforms to Edge and Chrome) I'm sure this can be easily fixed.

Last few days any Firefox 102.0.1.8221 launch causes my Windows 7 64bit to reboot, usually when I try to mouse click anything in Firefox after it's fired up and restored open tabs, however even if I don't mouse click anything Firefox will force a reboot within a minute or so.

This Firefox Win 7 reboot behaviour only started after the last Firefox update, though I would point out that around update version 100.nn I started getting failed update notifications from within Firefox which necessitated a manual newer version Firefox download and install.

Running Windows 7 in safe mode with networking on allows Firefox to function without crashing, albeit slowly and with no MSE protection available etc.

Only one crash report dated 16/07/2022 with following content: Crash ID: bp-d8383165-9c77-45e4-9929-a3ce12160527

Please note I'm sending this report via Firefox on my iMac coz that still works...
