Firefox 技術支援討論區

I just installed firefox on a linux machine, and spontaniously, I keep getting a message pop up toward the top of the screen saying: "To play videos, you may need to install the video codecs".

This occurs when I am not even trying to play videos. I can play youtube videos fine. I don't need to install anything. It normally occurs when I am checking my outlook email, but can happen at any time.

So my question is, how do I stop this message from coming up? Prefereably WITHOUT installing some codec that I do not currently need.

Another message that comes up is an offer to install an outlook extension to my browser, but this is triggered by opening outlook email. I have no need for this either, so it would be nice to get rid if this message popping up as well.

Thanks

Hello everyone, I wrote an add-on for my own personal use. I don't intend to publish it. So naturally, it isn't verified, but I trust it. I am able to install the add-on as a temporary add-on under about:debugging, and it works as intended. The manifest file contains "browser_specific_settings": {

       "gecko": {
           "id": "example@example.com"
       }

} I would now like to install the add-on permanently. So I packaged it as a zip file. The zip file contains the files directly without a parent folder. Under about:config I set xpinstall.signatures.required, xpinstall.whitelist.required and extensions.langpacks.signatures.required to false. Then I went to about:addons clicked on install add-on from file and selected the zip file. I got the error message: "This addon could not be installed because it has not been verified". I am using Firefox for archlinux, version 112.0.

What am I missing? How can I install this addon?

I apprechiate your answers.

The header bar at the top of the screen has disappeared from Firefox when run from my desktop computer (Image 1), but not when run from my laptop computer (Image 2). With the desktop, the maximize, minimize etc buttons are now on the same toolbar as the File Edit View etc buttons and there is no indication as to what website is being viewed. This problem occurs even when Firefox is run in Troubleshooting mode. Both instantiations are v. 119.0. How can I get the header back on my desktop instantiation?

And while I'm at it: With the current version of Firefox, the bookmarks toolbar is below the list of open websites, whereas several versions ago it was the other way around, which seems much more intuitive. Is there a way to switch them back so that the bookmarks menu is at the top?

Thanks!

I have the browser.urlbar.trimURLs switched to TRUE but still as you can see in the screenshot it shows the complete URL with the protocols. I do not want this, I want it to hide it and only show the main link like youtube.com instead of https://youtube.com

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

Which file/s contains only the browser settings, not including the extensions, which are transferable to other profiles? prefs.js? the contents of the settings folder?

So I have the tab bar hidden in 1.08. I have it going to self made userChrome.css file. This is the only thing in that file:

1. TabsToolbar { visibility: collapse !important; }

Issue is now I have no close button along with the other usual buttons with it. So what do I need to mod in that file to get them back?

Thanks

Hello,

I have more than 30 extensions, but I cannot add an extension shortcut into my toolbar and no extension appears in the “Customize Firefox” view. I tried “Restore defaults” without any effects...

There is a way to fix this issue or run Firefox in verbose mode to more information why my extensions don't appear here? (Other than restart from a new fresh profile if it's possible…). I confirm that all the extensions are functional and activated. Thanks,

I have always set my option for all download file types to "Always Ask" and now Firefox not only asks me where I want to save the downloaded file, but also downloads a copy to the Windows Download folder. Why am I getting double downloads? I only want one copy of a downloaded file, not two copies. Now I have to go to my Windows Download folder and delete the duplicate downloaded files. My question is, if my Firefox download option is set for all file types to "Always Ask", then why are you downloading the file twice??? I have specific folders where I want files to reside. I don't want to have to remember to go to my Windows Download folder and delete the duplicate files. How can this duplicate file download problem be fixed?

Long time user, Leo

How do I turn off web translation permanently for ALL pages in Firefox 118.0.1?? It´s the most annoying feature so far from Firefox. Even if I delete all languages in preferences, it shows up on every page I visit.

I've got a legacy transformer laptop with an integrated wacom-type sensor screen. Despite all shortcomings of it's age, the laptop's got class.

The main web browser installed is Firefox ESR. In tablet mode, control was handled by the Windows - mouse-like drag'n'drop, marking, but with added scrolling gesture by swinging quickly up and down. Using it in the tablet mode is actually very practical.

Recently, after updating from 91 to 101, browser started to interpret the pen as a finger, controls became clumsy and frustrating. The only way of turning finger gestures off, parameter gestures.enable_single_finger_input described in that question (https://support.mozilla.org/en-US/questions/973974) had no visible effect. Have fallen back to 91esr, but this is obviously just a temporary solution. Is there any way to add force-disable parameter or something?

Is there a way to permanently disable red underlining from Firefox spell check? This has only started occurring since an update to Firefox 110 (now on 112), but there seems to be no way to make it go away. I've unchecked the spelling box in preferences, and killed off things in about:config:

extensions.spellcheck.inline.max-misspellings 0 layout.spellcheckDefault 0 services.sync.prefs.sync.layout.spellcheckDefault false services.sync.prefs.sync.spellchecker.dictionary false

I'm using Mac Monterey, and have the global spell check turned off for that. This seems to be a problem specific to Firefox, as it doesn't happen in Chrome (spellcheck off) or Safari. I'd like to remove this entirely, since it's distracting to have it second guessing me whenever I'm typing. The main reason I use Firefox is that it gives me the ability to control many things, particularly in combination with UBlock, but I'm unable to make any progress in removing this persistent work disruption.

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

I can change the color of links and background in Firefox options. But i want only to change the colour of visited links on all pages and NOT also the colors of background and text. These 2 options are connected which is not practically i mean.

Are there addons who could do this? thx

This is more of a convenience issue but the new download panel pop-up from the download arrow is very distracting. I couldn't find an option to turn it off so I had to go into the config and turn the true flag false for this "improvement". Is there a better way of disabling this pop-up and if not will there be in future versions of firefox?

I've tried following both methods for dissabling the mute button on tabs, it's a slight annoyance, since it's easy to accidentally mute a tab when it's pinned.

Specifically, the first method I've tried changing the setting in about:config called "browser.tabs.showAudioPlayingIcon" from true to false, which was from 7 years ago it seems, which had no effect.

The second method was by making a new rule in a "userChrome.css" file in a new folder called "chrome" with that exact naming, case sensitive. The code in that file is as follows:

/* Hide the mute/unmute button */
.tab-icon-overlay:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) {
    display: none !important;
}
/* Keep site icon visible on hover */
.tabbrowser-tab:hover .tab-icon-stack:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) > :not(.tab-icon-overlay), 
     /* for site icon with Compact density */
:root[uidensity="compact"] .tab-icon-stack:not([pinned], [sharing], [crashed]):is([soundplaying], [muted]) > :not(.tab-icon-overlay) {
    opacity: 1 !important; /* overrides full transparency with full opacity */
}

If there's an updated version of the code that's meant to have that effect in modern firefox, then please let me know, or if there's some other new way of removing the mute button on tabs. Thanks.

After an update today, private browsing windows now are a different color than the other windows. I don't want them to be a different color. How do I change them back to the same as the other windows?

Also, how do I remove the extra text label next to the private mode icon, and just generally put things back to the way they used to look?

I can't get Firefox to use some custom cursors. Firefox is only recognizing the cursors that came installed with Ubuntu. Any of the cursors I installed will default to DMZ-White, but Firefox is using those cursors that came installed with Ubuntu. I tried defining the default cursor in /usr/share/icons/default/index.theme but did nothing as well. Also I tried with the cursor in /usr/share/icons and in /home/name/.icons and firefox cannot get in any of those.

I don't know if it's something wrong with my cursors or it's some inner thing with Firefox, any one has a guess? Incompatibility or something missing from the cursor?
