Diễn đàn hỗ trợ Firefox

Good morning, I have strange issue. Websites on my Manjaro Linux (GNOME desktop enviroment, using Wayland and Xorg) are not displaying correctly. Sometimes there are white fonts on white background-color, sometimes black fonts on black background. Sometimes where the bg should be white, it is black. I have Firefox Sync between my firefox browser on Windows 11 and Manjaro. Every setting in both browsers are the same. I tried to follow the instructions, like removing history, cache, cookies, turning off hardware acceleration etc. I just have no idea what to do now.

The latest Firefox update appears to break video playback on Linux. I am having issues playing video on Twitter, Facebook, and Locals. YouTube video still plays. I have not enabled any new ad blocking and have also not changed any settings. Looking at the Troubleshooting Information in Firefox reveals nothing that is suspect.

Certain fonts are displayed not as what I set them to in Firefox's settings.

At first, I thought it was a windows OS font related issue- it's not.

I've followed everything here: https://support.mozilla.org/en-US/questions/1323130 (The answer support link is inaccessible. But following the answer did not fix my issue.)

Also looked to see if any of my add-ons are affecting it. I've disabled them on the sites (in the screenshot) but the fonts are still displayed as attached. Checked to see if the add-on uBLOCK is disabling remote fonts, that feature is not checked so that's not the issue.

Please help, thank you.

I asked this a couple of years ago - ! But the problem apparently is BAAAAACCCKKKK.....

In my list of bookmarks I have inserted SEPARATOR lines. I cannot find how to delete a separator line. There doesn't seem to be any up to date information online about how to handle this - can someone help?

In the previous fix I would click the three-line icon at top right and to into MANAGING BOOKMARKS, where there was a way to see the list, and I could click on and delete any separator lines I wanted to remove.

Apparently in the newest version of FF this no longer works. Now when I go to Manage Bookmarks, there is a list of my bookmarks, but I don't see any of the separator lines.

I'd be truly grateful for help - thank you in advance.

I've blocked Autoplay (Audio & Video) for *all* Web sites via the settings menu, but videos still continue to play automatically (abcnews.go.com, for instance).

I went to config:about, and made all the suggested changes I found in Mozilla support. Autoplay seems to be blocked now, but at the expense of Firefox going into an endless loop trying to load and play videos. While in this loop, Firefox is eating up 20% of my CPU sources, which comes to close to making my PC unusable.

I have Firefox 109.0.1, 64-bit.

This has been a chronic problem ever since I've used Firefox. Someone needs to take a MUCH deeper dive into why we can't block autoplay.

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

WHERE IS MY BOOKMARKS TOOLBAR??? Every time I update Firefox (now 109), I end up with all kinds of problems! NOW, I can't see my bookmark toolbar. All the help articles tells me how to show it or how to bookmark a page, which I already did multiple times. But this issue is never solved. If I can't get this resolved, I'm going to MS Edge.

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

So this crazy new update has broken my Firefox in these ways:

1. All my bookmarks on my bookmarks bar have been deleted. 2. I can't drag any new links to the bookmarks bar 3. Overflow menu for apps is empty and will only let me drag Firefox defaults to it such as settings. Dragging apps to it is impossible. It "is" possible to pin items by using the Chrome puzzle piece..

Firefox: 109.0 OS: Windows 10 Pro

Using troubleshooting mode has no effect.

Hi, I'm running Firefox 109 on Win11 on a recent lenovo laptop with touchpad gesture and I can't find the way to disable a 3 fingers tap behavior specific to firefox.

I want 3 fingers tap to only open link in a new tab (mouse middle click) witch is working fine and match win11 touchpad gesture setting.

But in firefox, when I'm not exactly on a link, the 3 fingers tap is giving me a round with 2 vertical narrows and a dot (see screenshot below), and then any touch on the touchpad is scrolling the page, really fast if swiping vertically, or slowly if swiping horizontally.

I can't find any about:config parameter about this behavior. I found a lot of discussion about 3 finger swipe on Mac computer but nothing specific to three finger tap and scroll (Like Here or Here)

If someone has any clue, or just the name of this function that I could look for it, I can't translate it right to find anything. Thanks a lot

Hello,

There is a very long list of these that are associated with my account. I've imported my Firefox settings from computer to computer for at least twenty years. I may have made mistakes that caused me to pick up malware, and want to fix this, and some of these certificates have expired.

How do I know what to keep and what to either delete or edit trust regarding?

Is there any way to quickly and easily have all of them assessed at once?

Thanks very much!

I recently updated my system (OpenSuse15.4) which included a Firefox update to version 109.0.

I regularly use my mic for google voice, however even though I can select my microphone in Google voice, It never shows any input.

I tested my mic in other apps and it works fine. When I pull up my systems pulse audio volume control (pavucontrol), it does not show firefox in the recording tab like it used to when using Google Voice.

To test to see if it was a Google Voice error, I also tried testing my mic at https://mictests.com/, and zoom.com, but after selecting my desired input device, mictests.com was also unable to record anything, and again, pavucontrol did not show anything being recorded.

I have attached an image of pavucontrol that shows audacity recording audio. Normally, I would also see Firefox in this window when using the mic.

I am trying to put a shortcut to a web site on the Desktop. Using the the padlock on Firefox 109.0(64 bit) puts it in a sticky note on Desktop instead of a shortcut on the Desktop.

I am running running on Fedora 37 KDE where this does not work.

Using Fedora 37 Workstation (GNOME), the shortcut is created and works.

How do I get the shortcut to work on Fedora 37 KDE?

https://addons.mozilla.org/en-US/firefox/addon/lightorange-on-black/ there seems to be a problem with this theme, cant install, cant upload or anything it says its corrupted can someone help? please contact me under my email [email removed from public]

Okay, I give up. So, Facebook is or has implemented this Turn on two-factor authentication or whatever it is. What this means for me at the moment is that I am unable to access my Facebook account as it is now forcing me to use this Two-factor authentication thingie, despite that I do not have a mobile phone. (yes, I know it's unusual in this day of age not to have one. I did have one at one time, but for the moment I have no interest in getting another one). I would rather use my laptop anyway.

Doesn't Firefox have a Two-factor Authentication thing that I can use with Facebook? Without a mobile phone using the Firefox browser on a computer or laptop?

Now, from what I can see, Facebook is offering 3 ways of doing this. #1) Authentication app, like Google Authenticator or Duo Mobile. #2) Text message (SMS). #3) Security Key. So, because I do not use or have a mobile phone, I was guessing that my option would only be #1 Authentication app, like Google Authenticator ... which I have never used before, and while reading up on it, I keep reading that I can only use it with the Google Chrome browser?!? If that wasn't bad enough, I typically use Microsoft Outlook, not Gmail. So, I am at a loss at this point.

Again, I do not have a mobile phone. Doesn't Firefox have a Two-factor Authentication thing that I can use with Facebook? Without a mobile phone using the Firefox browser on a computer or laptop?

Help please.

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

so, my computer is getting old, and because of that, it's slowing then. Firefox isn't helping much because it uses too many processes and memory. i tried deleting some extensions, I tried using task manager to close separate processes but i always end closing the wrong one and closing firefox completely i tried going to dom.ipc.processCount and change the count to 1. I'm so confused, it's slowing down my games i play.

Hello, when I'm on a website that could use my microphone or camera, I am not getting the prompt to ask for permission to use them. I have tried manualy giving the website permission in CTRL-I website settings. But that did not fix it. I have tried the same websites in google chrome, and my mic works then.

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

I tried to Connect Dropbox to my desktop, but the page would not load.

Chrome has no problem loading the page.

Could someone please let me know if they have the same problem
