Diễn đàn hỗ trợ Firefox

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

For some time, maybe 3 updates ago, when I open Firefox with my many tabs, I have this problem. The first 3 tabs that I close leave a blank space the width of 3 tabs on the tab bar. After that any new tab opens to the far right spot at the end of the blank area. This happens in a private window too (extensions closed). After I close a session, then reopen later, all my tabs are still in place but the first 3 that I closed reappear where they were at the start. Strange.

The only Firefox will open a link in a new tab is if I force it to do so by right clicking each link and choosing open in new tab. Before it automatically opened in a new tab.

When I am scolling and the mouse hits an image, a large image preview appears. How on earth do I turn this off? I can see tab preview images to turn off but not this stupid image previre thing that covers everything I am trying to read or navigate on the web site.

Thanks very much M

Is it a known issue that opening JIRA web pages immediately crashes and closes the Firefox browser on Windows 11. It never happened on Windows 10 however due to Windows 10 end of life we've been forced to upgrade at work. Now this crashes on a key webpage (we're software delevelopers). So we might have to change to Chrome which I really don't want to do. It would be great if you could find any or many crash reports I've filed and fix the issue.

I've copied the crash report info here in case its of use.

We are unable to stop playback from the controls in the PIP window for Apple TV when the video playback was started in the main browser window. If we press the control the playbacks stops for a fraction of a second and continues again. Other controls like mute etc. are working as exspected.

If we start the playback in the PIP window we are able to stop it!

If we use Youtube or Amazon as a video source the problem does not show.

If we use Troubleshoot Mode we get exactly the same behaviour.

Any Ideas?

Slow website loading (30+ seconds) on some websites (the same ones) for over a week now. Have tried MANY things. No issues with MS Edge loading the same sites. Using Windows 10. Data copied. Help please.

Suddenly, Firefox is not auto-filling my passwords. I am experienced, and have gone over all settings multiple times. It is requiring me to click "manage passwords" and then copy from my saved passwords, and paste in the password, instead of auto-filling.

I am a Firefox user for the last 20 years. I frequently use Google Translate, and I depend on the voice-to-text feature. However, when I try to use it in Firefox, I get the message: “Voice input is not supported on this browser.”

Because of this, I am being forced to switch to Google Chrome, which I don’t really want to do. Is there any workaround, add-on, or upcoming plan to bring proper voice input support to Firefox?

I've usede Safari for years, but want to try Firefox. I've tried to import data, bookmarks and so from safari, but can't do it. Firefox says: Select the Safari file. But which one? And where do I find it? I've find the app Safari – but there's a lot of files underneath it.

Unable to pin extensions since i do not see the option to, clicking on the puzzle piece creates no drop down menu, when i go into the extensions menu the ... only allow me to remove or report, the manage extension shortcuts menu shows nothing.

Very annoying to deprive me of my preferred news source. Firefox refuses to load any link on Netflix

   Here is the message "The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

Please fix this or advise Thank you. David Vosbein [edited email and phone# from public community support forum]

Yahoo Finance stock charts are not loading. Never encountered this problem before this week. A GeekSquad tech support person was not able to fix the problem and recommended I contact Firefox. Edge and Chrome load Yahoo Finance stock quote sites just fine; I'm only having trouble with Firefox. Any ideas on how to fix? Thanks! Carol

When I login to amazon, it asks my user name (normal), then asks my password (normal), then when it sends a code to my phone, it freezes the entire browser and I have to force quit Firefox. Been happening a week, I've cleared history, run several programs (Malwarebytes and CCleaner-with normal results) and restarted my computer (Macbook Air running Sequoia 15.6.1). Any fix for this?

Just wanted to drop in here and give an update to my original post detailing how to hide the tabs and address bar when in fullscreen mode, using the View/Toolbars/Bookmarks Toolbar/Never Show command. With this css in place and the preferences set, toggling the bookmarks toolbar in fullscreen mode will toggle everything at the top of the FF window (but won't do that unless fullscreen is active).

This code changed recently (like, today) because the "collapsed" attribute from the #PersonalToolbar item no longer toggles between "true" and "false" when the user hides/shows the toolbar — instead, the "collapsed" attribute disappears entirely when the toolbar is showing, and reappears to be assigned the value "" (yes, empty) when the toolbar is hidden.

--- Here's the CSS. It goes into a text file called "userChrome.css".

root[sizemode="fullscreen"] #navigator-toolbox:has(#PersonalToolbar[collapsed=""]) {

 visibility: collapse;

}

--- On the Mac, here's the location. The CSS file then goes into a "chrome" folder in the "Profiles" folder located within your Mac user account's "Library" folder (not the Profiles folder within the Library folder on the root of the system drive, but the one in your computer account Home folder). You'll probably need to create the chrome folder. Just put the CSS above into a text file, name that file "userChrome.css" and drop it in the location shown below. Quit Firefox first, of course.

/Users/<user>/Library/Application Support/Firefox/Profiles/<profile>/chrome/

--- You'll also need to set the about:config options in Firefox to allow legacy user profile customizations. Go to about:config in the browser, and search for "toolkit.legacyUserProfileCustomizations.stylesheets" and set this preference to "true".

--- The code only updated slightly today. See my original "question" here: https://support.mozilla.org/en-US/questions/1448596#

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.

This may be a small issue but it's pretty bothering, I do understand that the web app as of now is primarily to be pinned at the taskbar, but would this be done in the start menu in the future? I mainly keep my apps at the start menu for my convenience.

Basically the problem here is the shortcut icon, so take this Messenger web app as an example. If I pin this to taskbar, or even make a desktop shortcut, it's showing the correct icon, it's also in the start menu but unpinned. However, when I pin it to the start menu, in the app catalog, it changes to the Firefox icon (for some reason the one on the taskbar sometimes does that as well).

I've tried looking into the Properties tab of the shortcut, but apparently it's already set to the Messenger icon, so I'm guessing it's primarily the start menu problem.
