Firefox 도움말 포럼

For some reason, the bullets used to hide a password are not rendered properly in Firefox. As shown by the first uploaded image, they are displayed as big white-filled circles.

This problem does not occur on chromium-based browsers, as shown by the second uploaded image, which is a screenshot taken from chromium, on the exact same session.

I have already done the following:

• verified that the "Allow pages to choose their own fonts, instead of your selections above" box is checked in my preferences. I have also tried disabling and re-enabling this option
• launched FF in troubleshoot mode to disable extensions and hardware acceleration
• verified that gfx.downloadable_fonts.enabled is set true in my about:config

All of these attempts however failed to solve the problem.

This problem is occurring on a fresh install of a Linux distro, so I first thought that I might be missing some fonts, but the problem might lie somewhere else since the symbols are properly displayed in chromium-based browsers.

Hi, this is going to be a long one, so many things... Using Firefox the latest Ubuntu LTS, with the latest Firefox from Snap. I'm a very long term Firefox user, never had any real troubles unit recently. I have a vast number of cookies, saved passwords and so on. Reinstalling or deleting cookies or such isn't an option unless fixes are guaranteed to work - if I have to start over then I'll do it with Opera, that is where my grumpiness indicator is at.

The set up is two monitors (working as a single 'screen') attached to an Aspire PC (Aspire X seems to be the model?). I tend to have 'stuff' going on in the left hand monitor, YouTube on the right. The PC is on all day. I know there are log files, but I don't know which is for what or where they are. I use AdBlocker Ultimate.

So what's happening is: Firefox crashes quite often at any time - 'Firefox is not responding - force quit or wait' - always have to quit. There doesn't seem to be any repeatable way to cause this, it seems random.

When the mouse enters the YouTube window (the drawing area, not the actual window) it disappears until the pointer moves out of the window. Jiggling the window size sometimes brings it back, but...

When the mouse pointer actually appears the window is completely unresponsive - clicks don't work, nothing highlights and so on. After somewhere between 10 and 30 seconds things will work for 2 or 3 mouse actions (clicks, drags etc) then do it again. Unless I give it plenty of time, clicking on a video will play a pretty random one - Firefox seems to lose track of where the pointer is.

If I comment on a video the I get about 5 to 10 characters in then nothing happens for 10 to 20 seconds, then any queued characters are shown. Rinse and repeat until the comment is complete - it takes ages.

YouTube is the biggest problem, but there are some glitches in other Firefox windows, I'm supposing that the problems are audio/video related.

None of the above happens with Opera. It's getting to the stage where Firefox is unusable.

I've googled and searched this site but the there seems no solution.

Any help appreciated.

I view a lot of PDFs for electronics design. And after some time with the browser running it starts to garble PDFs. I have not found a trigger. Sometimes it opens fine in a new container tab or private browsing, other times nothing will open it. Very occasionally refreshing a few times makes it load correctly. The error doesn't manifest for all PDFs at the same time. Open ones will remain viewable, and once the error occurs some new PDFs still open while others fail consistently. Sometimes opening the same PDF as a file from my local drive makes it render.

The rendering error is a bit unlike anything I've ever seen. There is a lot of X and Y spearing like it tried to render the same text and images in slightly different spots over and over again. When I switch virtual workspaces and come back some parts of the rendered page retain the contents of the previous workspace and others do not. Scrolling produces jitter and additional smearing.

One somewhat reliable way to trigger the error is to put the laptop to sleep and wake it up. That always causes PDFs to exibit this error but often refreshing the PDF will work to restore it. Not reliably though.

I've attached an image of the error captured with my phone because neither screenshots nor OBS can actually "see" the garbage on screen. Apologies that this error is so full of inconsistent behavior. I've lived with this for some time now in the hopes that it was a temporary problem and tried to work out what causes it but I can't find anything other than putting the laptop to sleep being a cause, and even then it is not the sole cause.

Lately, I used "Bing" in Firefox browser,but it often show no result and give one message about “Missing children". I think this is very strange, so I try to search in the "Bing" in different browser(Firefox and Chrome),and the test is confused. when I used this string "益云公益寻儿童" as the keyword for searching, there is only one result in Firefox browser but there are many results in Chrome browser.please see below images ( image 1 and image 2). At the same time ,there are also many results in "Baidu" in Firefox(image 3). Next I changed another keywords"天气预报",but there is still the big difference between them. when I Searching ,I closed all the plugins. So I think this is strongly related to Firefox browser. This phenomena makes "Bing search" very unpredictable so that I often got no result. please help me! thanks.

The blinking screen is on ebay but it just keeps on blinking. I have tried other programs and it only happens with this one and only with ebay. This is the new tab stuff: https://www.ebay.com/itm/401568771184?_trkparms=amclksrc%3DITM%26aid%3D777008%26algo%3DPERSONAL.TOPIC%26ao%3D1%26asc%3D265563%26meid%3D7245a46a376945799ec6d6e8ae3176fa%26pid%3D101967%26rk%3D1%26rkt%3D1%26itm%3D401568771184%26pmt%3D1%26noa%3D1%26pg%3D4375194%26algv%3DPersonalizedTopicsV2WithDynamicSizeRanker%26brand%3DFintie&_trksid=p4375194.c101967.m162920&_trkparms=parentrq%3A88a4a82d18f0ad8bbb523870fffffa70%7Cpageci%3Ab38440d1-149b-11ef-b242-1adf3ab78462%7Ciid%3A1%7Cvlpname%3Avlp_homepage&afsrc=1&mkevt=1&showcs=1

Thoughts?

I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

Sometimes a box pops up on the screen that asks if I want to block or allow something. Sometimes I have no interest in doing either, and just want the damned dialog out of my face. The page seems to work otherwise, but the stupid browser keeps the dialog over top of things, and clicking outside of it, and hitting Esc, don't make it go away. I think those actions used to work, and I think there, sensibly, used to be a dismiss option, but that seems to be absent now. There's no sense to trying to force me to make a decision I don't want to make, and doesn't even need to be made, and I want this thing to cut it out.

Hello when i am on facebook,and i want to do a video chat or a call chat it now tells me that video or voice calling is not supported by this browser,yet it was all working fine about a week ago and i went to do a video call two days ago and now i can't,i have no idea what has happened regards mark

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

I want to disable this redundant dropdown there is a post here from 6 years, but dont dolve my problem, I dont want to disable or separate the seach and the url bar, i just want to get ridoof this redundant information, just for curiosity, if i disable search or separate the bars, i still get the anoing dropdown but with "Visit" instead of "Seach with"

Currently, when I try and open downloaded .txt files and .log files (that is, when I click on them directly from the download pop-up that appears at the top-right of the browser), Firefox inexplicably opens Aegisub on my machine as the app to use. This is in contrast to when I open it directly from within my file browser, where it opens the Kate text editor, as suggested by the default app option in the permissions of the filetype.

How do I change the apps Firefox uses to open downloaded files? I've tried going into my settings and looking at applications, but .txt and .log don't appear, so I'm not quite sure what to do.

I'm on Kubuntu 22.04.3 LTS, using the Firefox deb package.

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

Hello, I administer a small fleet of Ubuntu desktops. For a variety of reasons we avoid using Canonical's Snap package version of Firefox.

Currently the fleet is using Firefox installed from the Mozilla Team PPA repo. However that repo can be incredibly slow and after reading about the new Firefox deb packages [1] from the Mozilla APT repository we would like to move to them. The problem is that these packages lack Apparmor profiles, so unfortunately my security team won't let me use them.

Would it be possible to add Apparmor profiles to these packages please? They would need to be applied only when an OS has Apparmor enabled, which may not be the default for Debian.

Thank you!

I using kubuntu (ubuntu with kde) 22.04 and firefox will not recognize my security key. There is a really good thread on this here. It is now closed.

https://support.mozilla.org/en-US/questions/1412073

One of the solutions is to install firefox from the mozilla server. On other forums, this is referred to removing snap and installing the debs. I haven't tried this.

Reading through the thread however, it seems like the snap version should work. The manufacurers id and product code for my Thetis FIDO2 usb key are present in the etc/udev/rules.d/70-snap.firefox.rules

This answer says to disable apparmor. I tried that, but it didn't work.

I have quoted this answer below.

This isn't actually a firefox problem. KDE Neon uses the firefox package from the Mozilla Team PPA and there's nothing wrong with that package. The problem is that Neon enables app armor on firefox which breaks access to password managers and security keys. sudo aa-disable usr.bin.firefox works around the problem by disabling app armor for firefox. aa-complain was not sufficient in this case.

Is there anything else I can try?

Hi, I'm using Firefox 125.0.3 64-bit with Linux mint and some of the tiles on the homepage have disappeared I have selected 4 rows in settings but only 2 and a half rows show, I can remove all rows and select 4 rows again but only 2 and a half rows will show all the edit, pin etc, options are there and work and I can rearrange the tiles but if I dismiss a tile it disappears completely, any help much appreciated. please see added image.

Steps for reproduce:

• Turn ON PC
• Launch Audacious player
• Launch Firefox
• Visit to drupal.org

And I have sound glitches like on radio tuning. From all software, that have sounds: players, browser, messengers. Glitches disappear after restart. I find only 2 sites, that make it: drupal.org and my local bank. With Chrome - no problems.

Without Audacious glitches can be to, but not in 100% of cases.

OS: KDE Neon Plasma 6

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?
