Over the last year I have uninstalled FF removed settings then reinstalled from scratch. Its been over a year now and FF never can pin point where I am at. Today it says I am 1300+ miles from where I am. I really don't want to go back to using Chrome but it appears I will have to as it normally has my exact position. I travel for 6 months of the year and have 3 internet connections shared via an internal WiFi that I use 99% of the time. They are connected via Starlink, GoogleFi (T-Mobile) and AT&T SIMs. I have a SSID with the _nomap suffix and that fixes Chrome but FF NEVER seems to know where I am, no matter how many times I clear the browsing data. I really don't want to go back to Chrome, but I cannot do my work if FF thinks I am somewhere else all the time. Geez, If only there was an addon or extension that would override FF location so I could tell it where I am. I'm in FF Hell. -Bill

Hail:

System Software: Win11Ent_x64 v22H2 (b: 22621.2283) MFF v18.5.0.0

No matter what I try, my MFF keeps crashing at startup. For some reason, it tries to open 2 pages the windows at the same time, which is illogical. I deleted firstly my: sessionstore.jsonlz4 logins.json to no avail.

Then I tried to open MFF through elevated CMD with the command: C:\Program Files\Mozilla Firefox\firefox.exe -safe-mode Again, 2 windows pop crashing immediately.

I do not understand why all of the sudden, it tries to open 2 different instances at once. This makes no sense. I am out of ideas, having tried many an option found on Google, but which none give me a solution.

If anyone has an idea, I would be quite darn thankful. This MSEdge crap that I need to use now is not quite my thing.

Thank you. Ke'Ylan

This is a recurring problem. I have just been on to Vodafone who have tweaked my router as my speeds, download and upload, were very erratic, and upload speed often zero so connections failed. Sometimes my phone speeds were similar but not always. The Speedtest by Oopla desktop app also showed erratic results but often when they were OK the web-based test on Firefox was much worse, with upload speed zero. When I started this Firefox showed upload speed zero. Now Firefox shows upload 18Mbps. This variability keeps happening and is driving me spare, as even emails often fail to go through - I use Thunderbird. I shall see how things go tomorrow and tell you how it is going.

Preventing Focus Stealing When Restoring Session

I am using Firefox 115.3 on Debian 12.1. I have numerous tasks which require the use of my web browser and have allocated a different virtual desktop for each. This means that my browser session typically has several dozen tabs open in numerous windows at one time. Under normal circumstances, this works just fine (and is a testament to the engineering that has gone into this browser).

My issue is that Firefox renders my machine virtually unusable for a few minutes each time I restart my desktop session due to focus stealing. When I open the browser, several dozen windows pop up (as expected) and relocate to their correct virtual desktops (as expected); however, as the windows begin to load, the most recently active Firefox window steals focus repeatedly. If I am, for instance, in the process of typing my password into my desktop e-mail client, a Firefox window may steal focus from the password dialog. In practice, this focus steal happens once every few seconds for several minutes.

I would prefer that Firefox would not steal focus while restoring a session. Does anyone have any suggestions for correcting this issue?

System:

Windows 10 pro 22h2 19045.3516

Intel i5-10200h with UHD 620

Driver 31.0.101.2125

Firefox ESR 115.3.0


When watching streams in firefox, I noticed that overall iGPU load is very high, up to 70%, a lot higher than watching 1080p movie with dedicated player.

I found that the firefox actually only shares 10~20 iGPU load, the rest are from DWM, which load is up to 40% sometimes.

Also found if I switch from the tab with streaming page to another normal webpage, DWM immediately drops its usage to about 2%, firefox still uses some load as it's still decoding. DWM usage rises if I switch back.

I tried force firefox to use nvidia dGPU, firefox does use nvidia card to decode, but the DWM problem said above still apply.


See attatched image as prove.

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!

Many bugs and crashes with Firefox

  1. 1 Not able to install an automatic update, via the Menu Help --> About Firefox (or Thunderbird). This bug / problems sits already inside the earlier versions of Firefox and Thunderbird.
  • A No new version is shown.
  • B Firefox (or Thunderbird) tries to download / install this update, bug become someway corrupted and also stuck in this process.
  • C Firefox (or Thunderbird) says to apply the update you must restart the program. After Firefox (or Thunderbird) was restarted, the program keeps trying installing or downloading this same or another update. I see a spinning circle only, no progress bar. Waiting, trying again later or another restart from Firefox (or Thunderbird) does nothing.

Only way to update Firefox is via https://www.mozilla.org/en-US/firefox/all/#product-desktop-release Which always shows the wrong language. Only way to update Thunderbird is via https://www.thunderbird.net/en-US/thunderbird/all/#product-desktop-release Here, I can click on letter from my language and download the setup package. After this update installation was done, the Help --> About (program name) window show the program is last version. But not seems not always the last version, like version x.x.01 to x.x.02, then tries to install this newer small version and gets stuck in the same loop or corruption.

  • D You must use the setup package, because the installer doesn't work, likes to abort the installation and shows error messages about something gone wrong. Installer package is incomplete or damaged, not for current version and Windows.
  • E For last newer versions, they seems not working anymore directly. The program can be restarted once or few times before it seems working. Until other bugs appear.
  • F Always adding a new and faulty shortcut, but I have already a working shortcut on my Desktop. Icon hasn't logo from Firefox or Thunderbird, but the setup icon.
  • G Sometimes you cannot start Firefox or Thunderbird, due the update did something wrong.

Missing file(s) and/or some strange error message after I clicked on the shortcut from the program. Another run from this "update" setup is needed. Remove a or all "Firefox.exe" from the Taskmanager list.

  • H Bug that stops add-ones working. This can be happen due the general function / thing for add-ones inside Firefox crashes, become bugged or corrupted. 1 add-one or more add-ones take the others and stop working, become bugged or corrupted. Add-ones will forget things, their work / functions or do it halfway. Has something to do with the installation and/or data from add-ones. They seems to not having support or do anything about their problems.
  1. 2 Random many crashes without any useful (error) messages, can be with closing the program itself.

Already from earlier versions of Firefox. And also Thunderbird too. This bug seems to sit deep inside the programs. I should be to use Firefox, Thunderbird, Notepad together, with having a some folders open. Switching between them can be annoying slow. Takes longer time be before responding. I'm seeing empty white or black windows. Only last selected section is visible, has the text and smaller pictures. I can have Firefox and Thunderbird left open for hours and later finding one or both programs are closed by itself. No reason, no permission given to do that. Add a new tab or click on a current site, there is no (fast) respond. Same for buttons, filters and filling in forms on a site. One program can pull the other program in closing to when the one is crashing. Also Windows will show several error messages about programs are using to much memory and must be closed. If this has programs listed, then Firefox seems to appear most here of the programs I'm using.

Updating doesn't fix anything Using the safe mode and new profiles are no long time solutions, every time anything is gone or nog working better.

It seems you must have 2 profiles running at same time when you want read something and not switching back between every minute or so. If 1 is near crashing, you have still the other one running.

  1. 3 Why I'm seeing 20x to 72x a Firefox.exe in my Taskmanager? They takes a lot of memory, showing different sizes. I started Firefox once. This is not needed.
  1. 4 Some sites seems to not work in Firefox or takes longer time.

Same for responding on clicking, using filters, buttons and sending forms. Clicking on those (annoying) accept (popup) windows. Unable to login or confirm an (security) action like this with a word or number given via e-mail. Might be something for the site. When you need to use Private Browsing for this.

  1. 5 Icons from installed add-ones don't appear in main bar, at right side. How to use them? Before they did.
  1. 6 Site using third party host sites are slow and mostly don't work. Connection errors.

"Seems fine here, but something with you". Refresh page doesn't fix it. Wait and try again later, how long? Firefox should block these sites.

  1. 7 After updating to Firefox version 115.0.2 and continue my last session, there are appear several new bugs.
  • A I cannot longer visit sites. Even earlier visited sites don't load. Firefox keeps stuck in loading or receiving site info data. Sites don't appear, just an empty (white) page. Also about:support doesn't work. Strangely, I can visit Google.com but not open any site from there. I tried Private Browsing, so no add-one can do something with this.

I had Firefox running for some hours, these sites are still stuck in "loading" or something else.

  • B Right click to open a site or page in a new tab doesn't longer work. Right click menu appears, but action will not be done. Which can be strange at top, missing or changed items.
  • C Same to copy line of text or picture, action isn't longer "remembered".

Now, I created again a new profile and again this doesn't fix them. Even more bugs and stranger. Again lost everything, settings, sites, installing dictionaries and add-ones. Stupid.

  • C1 I can visit websites, but with some strange things, not always working fine.

That makes it to post my problems here.

  • C2 Cannot longer type keywords in the addressbar and after pressing Enter, you should visit Google with search results. Firefox thinks the given keyword is a not existing website.

In Settings (via about:preferences#search), there are no search engines (Google, Wikipedia, ect) in the list, who should be there by default. Also there's no default search engine selected, the list therefor is small and empty.

  • C3 Yet visited near 10 sites, who I cannot visit any of the sites with my other long time using profile. Then Firefox crashed by random, white empty window. Windows adds not responding at end of the program's title bar. I could restart Firefox after that, get the "continue after a crash" tab and revisit any of these sites in their opened tabs.
  • C4 A site keeps saying cookies are disabled / denied, while minimal are accepted when some of that stupid (popup) windows did show. This means: Some stupid messages don't disappear after clicking "OK", the "X" or close buttons / links. Site might not work fine or on some parts. Something can follow you browsing through the site. Not able to visit that site or part.
  • C5 A site keeps saying there is an ad-blocker installed, but there is no add-one like that installed. This means: Stupid messages like these keep appearing; site cannot work fine; you cannot visit the site due some invisible wall or blocking thing. Some can follow you browsing through the site. This is very annoying.
  • C6 With one profile I cannot longer open sites who worked before. Keeps loading, shows URL in addressbar and on the tab.

And the about: .... pages. While with a new profile I can visit those sites, but right click menu is bugged.

  • Cannot open site or page in new tab. Only on Google based sites are working for unknown reasons, but not YouTube.
  • Missing items or I can see more gray things and lines.
  • Cannot copy selected text. Stil having old or wrong text.
  • Cannot Search with Google, this option is missing.
  • Cannot see the source code from the page, due action is not happen.
  • On sites that are working you can only read that current content. Can open links in new tabs, but their pages are empty / white, keep loading forever.
  • A few sites don't load and still giving a empty page. Loading takes longer then needed. For same site.
  • Use Google by typing the keyword in the addressbar doesn't visit Google site, but Firefox thinks the site doesn't exist, is wrong typed. You must go to Google.com and typing the keyword in the textbox here.
  • If a site worked first, then later it cannot working longer, keeps stuck in loading and showing a empty white page / tab.
  • Login for some sites is not longer possible, email send with security word or number doesn't appear. I can send myself a test e-mail to this e-mail address. Waited the time enough and made a new attempt, still the same.

Windows PC. Firefox version 117.0 x64. Via Help --> About Firefox, because about:support doesn't show the version and build.

Hi all, the shortcut to close a single tab (ctrl+W (Windows) or cmd+W (Mac)) is not working anymore.

here is what I tried so far: - disabling all extensions (via restart in safe mode) but to no avail - reinstalled Firefox but the problem persists - verified, that the command is indeed cmd+W and was not changed by accident - all other shortcuts are working well

NOTE: I can see that when I press cmd+W, the "file" tab up above on the Mac menu bar flashes for a brief moment, as if the system detects the shortcut. But the tab stays open.

Any other ideas I could try out?

So for the last little while, Facebook has been making a complete nuisance of itself on firefox. This isn't a browser problem, because the other tabs I have open work perfectly fine, but FB takes forever to load, and any button I press to interact with it, (like the reload button,) also lags, (but, again, works fine on other tabs,). It doesn't even register links as being clickable for a good minute after loading. The page also seems to reset every time I switch from another tab to it, showing a blank page with a loading symbol. I have tried deleting the entire history, and restarting the browser, and deactivating the adblocker, (the only extension active) and nothing seems to help. Does anybody know why it's doing this, (other than because the company follows the 'if it isn't broke, break it' theory, which we all already knew,) and how to fix it?

When searching queries, this error will come up; however, when searching full length URLs it works and sends me directly to the website. I've looked through the Q/As and they all recommend clearing cache/cookies and messing with the history settings to resolve the problem. However, after doing all that and messing with other settings I cannot seem to understand why this started to happen.

When in private browsing mode it works fine and I can ask whatever and I receive all the possible websites to click on. It's just on normal browsing that I receive the error message. Am I going to need to just uninstall Firefox and reinstall to fix this? Or maybe there's something else I can try out. Thanks!
