Firefox Support Forum

When I open a website where there is a document upload feature and I want to upload a document but when I click the button to upload a document Firefox can't respond, I've tried several methods such as deleting cache, even reinstalling but I still encounter this problem.

I can't add images to this report because of this problem

Thank you

This blue icon recently appeared in the upper left corner, and it's there even when I watch video full screen. Clicking on it doesn't do anything. What is it and how do I get rid of it when I want to watch video?

Hi, I am using Firefox 118.0 for Fedora that comes with my Linux distribution (Fedora 38 Kinoite). Everything was working fine, but as of today, when I try to start Firefox from a taskbar, my entire desktop goes black for a second and then returns to normal with Firefox not starting as if I didn't click on the icon at all. However, if I open the Terminal and run Firefox from there, everything works fine. I am not sure if the problem is related to Firefox, KDE Plasma or Fedora, so I will start here. I attach my system info below.

Terminal output (Firefox works fine from here): $ firefox Crash Annotation GraphicsCriticalError: |[0][GFX1-]: vaapitest: ERROR (t=0.40708) [GFX1-]: vaapitest: ERROR Crash Annotation GraphicsCriticalError: |[0][GFX1-]: vaapitest: ERROR (t=0.40708) |[1][GFX1-]: vaapitest: VA-API test failed: failed to initialise VAAPI connection.

Operating System: Fedora Linux 38 KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.109.0 Qt Version: 5.15.10 Kernel Version: 6.5.5-200.fc38.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-8550U CPU @ 1.80GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 Manufacturer: LENOVO Product Name: 20L8S0SA00 System Version: ThinkPad T480s

Hi; Search engine does not open in new tab. This is not how it used to work. Not sure when this started, possibly when windows updated to Win11(2 weeks ago), but not sure. I think there used to be a setting for opening a search in new tab, but I can not find it. I have "Add search bar in toolbar" checked. I use DDG as search engine. I did lookup in FF help but found 10yr old answers. I am sure many things have changed since then.

Also when searching FF help is there a way to sort by newest first?

TIA

After upgrading Ubuntu from 18.04 to 22.04, I attempted to import my old profile data into the new version of Firefox (118.0.2). All attempts following the instructions at [https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-fire...] failed.

Following the instructions at [https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing...], I deleted the profile.ini file.

Since then, Firefox does not open. I still get the message "Your Firefox profile cannot be loaded. It may be missing or inaccessible." The only option is to press the OK button at which point, FIrefox closes.

There is no current information in the crash logs and I can't find any error logs.

Mouse is Logitech MX Master 3 for business. When I scroll on Maps to zoom out or in, it zooms all the way out or in, even when I just do one "scroll click". Scrolling up and down works fine on other websites. Using the scroll wheel for zoom in Google Maps in other browsers (latest versions of Google Chrome, MS Edge, Brave) works as expected/fine, there it only zooms out/in one level.

It's not a new issue, it's been here for a long time, I just haven't bothered doing anything about it.

I have found another old thread about the same issue and the suggestion was to disable hardware accelleration. I tried that and it made the scrolling worse, but same thing happens, just slower and with choppiness. I have tried running troubleshooting mode. Still the same thing.

Hello. Can someone please explain why Facebook asks for username/password every single time Firefox is restarted? I do not use cookie-cleaning extensions. They also send a 'login attempt' email and phone notification every time.

Tried with and without Facebook Container. Not using other Container/multi-account related extensions. My settings:

Standard Tracking Protection (allow/block exceptions: none) "Do not track" signal: Always Delete cookies and site data when Firefox is closed: disabled (no exceptions) History - Firefox will: Remember History

Thank you

I am running Firefox 118.0.2 64 bit on windows 10 22H2. For one particular website I get a 403 error on Firefox, the site opens normally on Edge. I do not have any add ons or extensions that block websites. I have cleared cache and cookies and tried to open the site in troubleshooting mode, no luck. I have also disabled BitDefender, same results. Any suggestions are appreciated.

Hello, everyone.

4-5 days ago, I've noticed weird YouTube playlist behavior. When I start playlist and switch to a different tab (or minimize browser) first video will play normally and it will autoplay the next one. But after finishing playing 2d video (3d in some cases) video will just stop at the end of playbar and not autoplay the next one in playlist. Playlist for example: https://www.youtube.com/watch?v=giUY_pEKTzY&list=OLAK5uy_nKmglmCCbx14WeFyH8e7YGYcL5skYwnp0&index=1

It's rather easy to replicate, I can record desktop video if needed.

Expected behavior: I can start YouTube playlist playing and switch to a different tab or minimize browser and playlist will only stop after playing last video in said playlist (unless "Loop playlist" option is enabled).

What I've tried to do so far: 1) Googling: I only was able to find old thread and the culprit was extension: https://support.mozilla.org/en-US/questions/952608 2) Disabling Extensions and confirming issue in Troubleshoot Mode: Did not help 3) Clear cache & cookies for YouTube: Did not help 4) "Allow Audio and Video" autoplay for YouTube: Did not help 5) Confirming issue in another browser: Works as intended in Opera 6) Checking about:config: I'm not that savvy with Firefox config to understand what may cause an issue. Tried to change media.block-autoplay-until-in-foreground to False. Did not help, rolled it back to True.

What I have noticed: 1) Firefox recent update: 118.0.2 October 10, 2023: Correlates when I started experiencing this issue. 2) YouTube playlists plays next video continuously just fine if I don't minimize browser or switch to a different tab. 3) There is a Firefox extension that does exactly what I don't want in my experience: https://addons.mozilla.org/en-US/firefox/addon/no-playlist-autoplay-for-yt/ I installed it just to check. And yes, it does what expected and it is similar to what I'm experiencing. Although it stops playlist after finishing first video, my issues go into the affect after playing first video. (Deleted it after testing)

Before posting I've tried a few different things and here where things gets extremely weird: 1) It works just fine in Firefox if I log out from my YouTube account: (Incognito/Main tab) Do not work if I'm logged in, even in Incognito. However... 2) It works just fine in Opera if I'm logged in my YouTube account. 3) It works just fine if I open playlist in mini-player. (Current workaround)

After all that weirdness I attempted to Clear cache & cookies for YouTube and it did not help once again.

P.S. Yes, I use YouTube as a music player. :)

My Firefox 118.0.1 on Win 10 (all current updates) is creating literally thousands of profile files daily. For example, at this moment there are 3957 profile files with names like

6D89348819C8881868053197CA0754F36784B4BFSF

in the directory C:\Users\(user)\AppData\Local\Mozilla\Firefox\Profiles\ywlawdlc.default-release-2\cache2\entries

There are also thousands of other profile files in folders from previous dates.

What is the purpose of this many profile files, and how do I stop their creation in such quantities?

Thanks Dave

Firefox cannot play IMDB video. It shows: This video file cannot be played error code 224002 Youtube and other video contents are working fine but IMDB. Chrome and other browsers are playing IMDB video without any issue. Why Firefox does not? Is there anyone who knows how could I solve this problem?

Thank you!

Hello, what's wrong with the bookmarks thumbnails, that they don't display properly (not as the site's logo), only some default ones that look ugly. Only some tabs have thumbnails. I have freshly installed firefox on a new PC and I've been using it for another day and nothing changes, I visit these websites constantly and these icons still look like this. It will stay like this or is it some browser error ?

Greetings

Tom

For several days I have been receiving pop up scams as illustrated in the first image attached. They repeat themselves every few minutes. The second image is what I received on the website listed at the bottom of the pop up - brnok. stoneheartseeker.top.

How do I stop them, please?

Also, is there a legitimate connection between Mozilla Firefox and brnok.stoneheartseeker.top?

I'd much appreciate your help. Nicholas

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?

Can't get past "This browser is no longer supported" message when trying to access "twitter.com". Have turned off all known ad blockers. Reload produces same result.

there used to be an add on called roomy bookmarks that stopped working so people found ways around to replicate it and it works on win 10 but I just switched to Win 11 and this solution doesnt seem to work anymore for me, anyone know if i need to change anything?

    Locate your firefox profile folder, in this article they say where you can find it: http://kb.mozillazine.org/Profile_folder
   Find your profile folder mine was: C:\Users\***\AppData\Roaming\Mozilla\Firefox\Profiles\***.default\
   Locate a folder called chrome (if it doesn't exists create one through your O.S) must be lowercase
   Locate inside chrome folder the file: userChrome.css (if it doesn't exists create one through your O.S, google how to create a .css file on notepad) Chrome must be cased as shown above
   Add the code: https://pastebin.com/1r6cc8hW
   Restart Firefox, now you are done, if you don't want text to be displayed within the icons just remove the last line. 

This is the line of code i have in css file that works for me in my win 10 machine.

/*

* Recreates the basic functionality of the popular Roomy Bookmarks Toolbar add-on in Firefox 57+.
* Uncomment the section with the functionality that you want, leave all other sections commented.
* This only affects toplevel toolbar bookmarks and folders, bookmarks and subfolders in folders are unaffected.
* The tooltips on long hover (showing bookmark name and link) are unaffected.
*/

/* some margin settings, do not comment out */

.bookmark-item > .toolbarbutton-text {

 margin-top: -1px !important;

} .bookmark-item {

}

/* No text on toolbar bookmarks; Text on bookmark folders. No hover effect. */

1. PlacesToolbarItems > .bookmark-item:not([container]):not([open="true"]) > .toolbarbutton-text {

}

does anyone have a workaround or a similar add on? i would like to have my booksmarks as shown in the screenshot on my win 11 pc as well.

Hello,

I deployed my NextJS app on Vercel, but I cannot access my deployed app through firefox because of HSTS.

I tried to access several sites with domain .vercel.app but the issue persists.

I can access all sites with ".vercel.app" domain just fine on other browsers except Mozilla Firefox.

I already looked for solution on the internet such as:

1. Removing entry on SiteSecurityServiceState.txt
2. Forget site
3. Clear browser cache & history
4. Restart browser

Any help will be appreciated.

Thank you for your time and attention.

I updated from version 106 to the latest version just now and my user-defined fonts stopped displaying on a local HTML page (stored locally on my computer); this warning showing up in the console: "Request for font FONT_NAME_HERE blocked at visibility level 2 (requires 3)."

I specify fonts using "font-family" property (CSS).

Help me out here, please. How can I fix this (so my pages look proper again)?

Thank you.

Hello, i have the issue that times are displayed in UTC as long I have enabled fingerprint protection. Is there a way to exclude time zones or to manually set the timezone I want?

I found this in about:config: privacy.fingerprintingProtection.overrides: string

Can I override the settings for the timezone?

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

• Turning off syncing in Firefox on both devices.
• Signing out of Firefox from both devices.
• Disabling "sync open tabs" via Firefox preferences
• Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
• Reinstalling Firefox
• Deleting cache from both Firefox and Chrome.
• Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!
