Firefox Support Forum

When I select in Settings>Privacy & Security>History, that a history should never be saved and close the Settings tab, the next time I go to Settings, the option is replaced by the setting, that saves a history according to customisation and there's a check mark to always use the Private Mode. Apparently Firefox doesn't keep or save the setting. I learned from https://support.mozilla.org/de/kb/privater-modus that saving a history according to customisation with the option to always use the Private Mode enabled, is the same as never saving a history, nevertheless it should be possible to keep the setting (as the setting exists). How can I solve the problem?

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

I'm encountering consistent video playback issues on Firefox while running Fedora 38. The error message I receive when attempting to play videos from certain sites, notably LinkedIn and Twitter (now X), is:

• The media playback was aborted due to a corruption problem or because the media used features your browser did not support.*

Furthermore, when examining Firefox's console while attempting to play a video, I observed the following error:

• [Child 5999, MediaDecoderStateMachine #1] WARNING: Decoder=7fdb3c55a100 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - mozilla::MediaResult mozilla::FFmpegDataDecoder<60>::InitDecoder(AVDictionary**): Couldn't open avcodec: file /builddir/build/BUILD/firefox-118.0/dom/media/MediaDecoderStateMachineBase.cpp:166*

Steps to Reproduce: 1. Navigate to LinkedIn or X (previously Twitter). 2. Attempt to play any video content. 3. Observe the aforementioned error.

Additional Details: - OS: Fedora 38 - Firefox version: Initially 117.0.1, then updated to 118, both 64-bit. - This issue does not occur on Google Chrome on the same system. - I have attempted the following troubleshooting steps without success:

 1. Updated Firefox to the latest version.
 2. Enabled DRM content.
 3. Booted Firefox in Safe Mode.
 4. Disabled hardware acceleration.
 5. Cleared cache and cookies.
 6. Used a Flatpak version of Firefox.

This issue has significantly impacted my user experience, and I hope to find a resolution soon. Any assistance or guidance would be greatly appreciated.

Thank you!

For the past few days, the YouTube website has behaving unusually in Firefox. The volume and play/pause controls don't work. The picture in picture mode does not work. And most importantly, the search bar is broken. Whenever I type something and click the search button or press enter, the value entered disappears and I have to type it all again, only that this process goes on for infinite number of times and so, I can't even search for anything on YouTube.

Firefox used to have an option to put tabs back under the address bar, it is missing. I don't want to mess with custom css files every update when mozilla breaks things again.

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

Hello,

I need help i'm using polish language always on many websites.

When i typing letter "ó" which using key combination Right ALT+O always my brower opening "Open file" dialog window. this is annoying always.

Many sites write that it can not be changed?

Why does the browser open this dialog with this shortcut when there is another shortcut for it? Ctrl+O. Why two another shortcut doing te same job?

I am running Firefox-112.0(64bit) on Debian Bullseye. When I pend Firefox I am presented with a blank page rather that my normal sign in page.

Opening a terminal window and starting Firefox with /opt/firefox/firefox generates the following errors:

comp@AbNormal:~$ /opt/firefox/firefox [GFX1-]: glxtest: VA-API test failed: no supported VAAPI profile found. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. [ERROR glean_core] Error setting metrics feature config: Json(Error("EOF while parsing a value", line: 1, column: 0))

If I enter a URL the page opens and is usable.

How can this problem be fixed?

Thanks in advance.

been at it a week everywhere. how can I change the resresh rate about 60MH. desktop preferences is greyed out. command line didnt do it. not a programmers, please keep it simple. was hoping a GUI would make life easier. its blocky on a slow screen scroll. tried loads everywhere. I think it might not happen in chrome.

I'm the tech director (tech janitor) for a public school that is using Securly.com for their Internet filter. Securly requires installing their own certificate so they can be a man-in-the-middle. I've installed that cert into Firefox and that works fine. However, even with that cert installed, Sync doesn't work when I'm behind that filter. As soon as I take one of my computers off the school network, everything will sync up. I don't get any errors that sync is failing, it's just not working. Any ideas on how I can fix that issue?

Thanks!

I stream video and after 10 minutes, graying out of screen or simply the steaming stopped. Repeatedly same problems. Problem for same streaming not seen using chrome.

I do online payment and screen locks up. I refreshed... no change. I paid in chrome... no issues Now notified that I may have paid twice. WTF?

Why suddenly problems with firefox.

Running Linux mint

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

Fix the confirmation email process so it works. Tell me how Firefox lost my signed in status. Tell me why there is an added 1 after my user name of bth73. Drug test your employees for meth usage.

Web page loads incorrectly. so far this is the only page, the same time on other computer all is ok. cookies and cache is clean. Linux Mint 21.2 Cinnamon 5.15.0-83-generic Firefox 117.0 (64 bitu)

nsandi.com asks for cookie permissions on every page despite accepting cookies on previous pages.

I raised this with them and they said it was because I am using an unsupported OS, I am using Ubuntu 22.04.3 LTS and FF 117.0 (64-bit) - which they do support.

If I use a different browser, Opera One(version: 102.0.4880.40) on the same machine it is not a problem.

Is there anyway I can make this work correctly using FF?

Hi,

I running Firefox on Ubuntu Lunar. Every thing is updated, Software Updater doesn't find anything to do. Neither does looking for updates in the extension manager.

I have a lot of extensions installed, probably too many. They include several malware, tracking, popup, and ad blockers. I'm surprised they seem to be playing well together without stepping on each other. When they do block something I need, it's hard to tell who blocked that and then fix it. Is there an easy way to find which one did the block?

Could the multiple blockers be interfering with each other in subtle ways without me noticing?

I have some false alarms where at first I thought extensions were interfering with each other. There are a few extensions that don't work: Dictionary Anywhere, Don't Track Me Google, and To Google Translate among others. When I click the puzzle piece extensions icon in upper right corner, they are grayed out and can't be used. I tried disabling all the other extensions and tried each one at a time by itself. They are still grayed out.

Any ideas?

(It may be "website broken" but I fear it is more this part of the problem)

Sorry folks, I know I don't help here much yet am often asking questions.

Base line: This machine Firefox Ubuntu 22.04 LTS Lots of pages/tabs open. 4 very specif tabs: 1 - this machine. 1 - RasPi #1 1 - RasPi #2 1 - RasPi #3 1 - RasPi #4

I use Node-Red on all 4 machines. So I have the tabs open on their "edit screen". I have a "dark theme" loaded - saves burning my eyes.

Until very recently things have been good. Example: Pic 1 And another part that is correct. Pic 2 All machines are running the same version of Node-Red with the same settings for how the "edit screen" is shown.

Suddenly - and alas I don't have a screen shot of one of the problems - the colour scheme is corrupt.

Example of a problem. Problem1 I can't see things until I move the mouse over them.

the other problem - which has now gone away - is the background as shown in pic2 is white.

Until today this problem didn't exist.

I am asking here as I want to check all possibilities.

SUSPICION 1: A LONG TIME ago I asked for help with the log in screen for these three remote machines. The colours were wrong and at the log in screen I was seeing text similar to how it looks in 'problem1' picture.

I adjusted the colours to something else and it helped the problem. Not exactly 100% good, but it did make the contrast better. Has that *crept into* causing this problem?

By opening a private window and logging in this is what the login screen looks like: login

Sorry I don't know how to make them appear as inline but I've named them as per how I called them here. (edit) SORRY, I see that the names were not exactly honored and they were given different names. I hope you can see what is what.

(edit 2) Ok, something else that doesn't make sense. The third of the remote machines. It's colour scheme is working fine. It is the same as the first two. RasPi. Buster. Ok 1 and 2 are V3 and 3 is V2.

BUT! Ok, saying what I just said/suspect is true: HOW did it happen? It was working for .... years. No problems. Suddenly **BANG** it happens.

Thanks in advance.
