Firefox Community Forum

Hello,

For two firefox updates, I've been having an issue where after about an hour or two of using firefox (it varies), video players on most websites will stop working. Almost every website except for Youtube's videoplayer stops working after an hour, all at once. Restarting firefox fixes it, but it's very annoying to restart firefox every couple of hours, and seems like a problem.

The following things didn't fix it: clearing my cache, disabling my addons one by one, turning off hardware acceleration, trying to watch the video in a private window, or reinstalling firefox. I don't know what's left to try. It has nothing to do with my audio devices.

Please advise, thank you!

This computer is about to crash so I have a laptop backup. I have copied my Firefox profile before from my last computer to this one that is crashing without issues at all. It copied all of my bookmark data, settings, logins, themes, add-ons, etc last time. This time it refuses to read any of the files copied. No add-ons, no bookmarks no nothing. I need this taken care of ASAP as this comptuer is on it's way down and the monitor likely only has days left the way it's running. Why does copying profiles no longer work? I know how to do it and I did the exactly the same as I did before. It's been an hour fighting with it and nothing is working. I need this done ASAP.

I use Firefox to download, copy, and store WikiSpecies pictures.

Currently, my .../Documents/WikiSpecies/Animalia_Plantae_8 directory holds what it says are 90,876 items, totalling 11.5 GB. I have plenty of unused space in that directory (over 91 GB), so space is not an issue.

Lately, when I try to install a new picture, I keep getting a warning that the picture is already stored. This MAY be because I am running out of new pictures, but I can't tell.

Is there any capacity limit to a WikiSpecies directory?

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

Hi all, is expired cookies management changed lately? Authentication doesn't work anymore in following use case. Question is all about FF for windows, while usually I'm on FF Android, Edge and Chrome for Windows and all these browsers are working correctly.

My working web app (static blazor wasm standalone) is interactively authenticating in Azure AD B2C using Microsoft.Authentication.WebAssembly.Msal library (like MSAL.js), API is an Azure Function protected through AAD B2C.

Login request successfully invokes Signin/Signup B2C flow with popup to myb2ctenant.b2clogin.com but breaks navigating to auth protected pages or backend apis.

From DevTools I see that every request to following b2c endpoints sets an expired cookie (expired 10 years before, year is now 2012):

When user clicks login: GET /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/v2.0/.well-known/openid-configuration

Returning from login confirmation: GET /myb2ctenant.onmicrosoft.com/B2C_1_SInSUp/api/CombinedSigninAndSignup/confirmed?rememberMe=false&csrf_token=xxx

for example: Set-Cookie: x-ms-cpim-trans=; domain=myb2ctenant.b2clogin.com; expires=Fri, 14-Sep-2012 12:46:46 GMT; path=/; SameSite=None; secure; HttpOnly

FF registers this warning in console:

Cookie “x-ms-cpim-trans” has been rejected because it is already expired

Following when MSAL execute a request to /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/oauth2/v2.0/authorize?xxxx

Response always contains:

Location: https://blazorapp.xx.web.core.windows.net/authentication/login-callback#error= interaction_required&error_description=AADB2C90077%3a+User+does+not+have+an+existing+session+and+request+prompt+parameter+has+a+value+of+%27None%27.%0d%0a

All other browsers are working... Thanks in advance for any help

Hello!

I'm using Firefox MSIX on a laptop with an OLED screen. To avoid burn-in, static elements on the screen are discouraged.

Unfortunately, when the Reader View is enabled on Firefox, a vertical toolbar appears and is constantly on the same spot on the screen.

I would like to have this toolbar disabled or have it to hide/show depending on mouse prompt. Is there a built-in setting I could change to make this happen?

Would this solution here be my only option and would it work on Firefox MSIX? Finding the firefox profile on the Microsoft Store app is tricky.

Thank you.

I can't connect to my router using this same link I've always used: https://router.asus.com:8443/ I also tried: http://router.asus.com and: http://192.168.1.1/ Nothing has changed! I get a security error. See attachment. There is no "Proceed at your own risk" option. I've spent hours searching for a work around or fix. Nothing works! How in blue blazes am I supposed to connect to my ASUS Router's GUI. This is Windows 10, Firefox 104.0.2 (64-bit)

I'm a gamer and alt+tab considerably often. Most of the time I end up on FireFox because I need to look at a map or browse reddit while I'm in queue. However, whenever I alt+tab frequently a bookmark will get selected as if I am clicking and dragging. The bookmarks on the bookmark tool bar always end up in different places. Is there a way to lock these links in place so I can't move them or do I have to resign myself to fixing it every day?

Firefox is forcing me to download a lot of temporary files instead of opening them in their native application, resulting in cluttering up my hard drive and making me unnecessarily having to clean up after the browser.

How can I fix this privacy invading feature?

My System Mechanic malware search system has quarantined a virus located in two Firefox locations: Virus is W32/Trojan.YZST-9002 LOCATE IN: C:/PROGRAM FILES/MOZILLA FIREFOX/UNINSTALL/HELPER.EXE C:/PROGRAMFILES/MOZILLA FIREFOX/MAINTENANCE SERVICES_UNINSTALL... I will use the delete process and remove them and watch for future loads.

Once again Firefox adds a feature I don't want and can't disable. I want not to have a tab bar. They take up too much screen and get in the way. So I fond code that eliminates the tab bar unless there is more than one tab. Then the latest release addes the 'search tab' down arrow I neither want nor ever asked for and I can't get rid of it.

Why do you insist on doing this Mozilla? How do I turn this useless feature off?

When plugshare.com loads, there is a prominent search box at the top left corner. However it is missing the menu icon (see attached pic) as well as the search icon. This is happening on 2 different machines running Ubuntu 22.04.

Please fix. Google Chrome displays just fine; see attached pic.

Preamble: for most of the day I have Firefox open with several tabs. For a specific project I want Firefox open with one tab showing a specific webpage. At the same time I don't want to delete the existing tabs in the existing instance of Firefox - I want to keep them running in the background. Question: how do I create a desktop shortcut which opens a new single instance of Firefox with a single tab showing a specific URL ?

Hi,

I'm using IPv4 as well as IPv6 addresses in my home network. But Firefox uses always the IPv4 connection when I open a website. When I open the same website in MS Edge, the IPv6 connection is used.

I've captured the network traffic during opening a website in Firefox, which is reachable over IPv4 and IPv6. First I see two DNS queries (A and AAAA) for the domain name. Both responses containing the correct IP address, and they arrive nearly at the same time at the client. Next I can see the TCP handshake. But it's send between the IPv4 address only. No IPv6 connection was attempted.

When I run the IPv6 test at https://test-ipv6.com, the IPv6 resuls are nearly fine. Only the web browser test says "Your browser has real working IPv6 address - but is avoiding using it."

When I run the same test in MS Edge, all tests are fine.

So it seems that this is not a OS or network issue. It affects Firefox only.

What I've already tried:

• Disabled all extensions
• Created a new profile
• Used the IPv6 address of the website instead of the FQDN -> Works fine.
• Checked DNS cache of Firefox (about:networking). It contains the IPv4 and IPv6 addresses of the requested websites

I guess that Firefox prefers the A record for some reason. But I've no idea why. Has anybody an idea what could causing this?

Thanks.

Firefox update required me to restart Firefox. I was unable to save a bunch of work I had done in a particular tab because Firefox seems to have refused to connect to the site I was working at until I update. THAT SUCKS!

Occasionally, when I am watching a video on Youtube or Twitch, the video will glitch and cause the browser to go completely white. On Youtube, there will be a small visual glitch and on Twitch, the video will crash and need to be reloaded, but otherwise nothing else happens.

www.google.com. PR_END_OF_FILE_ERROR www.facebook.com. PR_END_OF_FILE_ERROR Hi, This occurred after a moment of power loss during a thunderstorm on my Lenovo desktop. All my other sites as far as i can tell are ok. I used Edge and was able to access FB and Google on Desktop] i checked and the current version of firefox is installed on desktop

even weirder, i can access both google and FB on my laptop with firefox. I've tried syncing the two with having bookmarks etc. i can sync from laptop to desktop but not vise versa.

i thought I'd uninstall and reinstall firefox but i don't want to lose any info esp my Bookmarks on the Desktop hence why i was trying to sync the two.

My desktop is older, maybe 5-6 years, my laptop is 1 year old. Dunno if this matters. thanks, Jan

Hi support team,

Yesterday, I suddenly removed all logins and somehow my profile was synced to the cloud.

Fortunately, I still keep all login files (json and key db files), I tried to recovery all my logins, it was successfully.

But, right after that my profile was synced from the cloud to my machine then whole logins were clear.

So how can I overwrite my profile in the cloud so I can totally recovery my old logins?

Kindly help to give my some advice.

Thanks!

My new Windows 11 laptop forces me to use the "Mail" app to forward links by email using the "email a link to this page" utility feature in the Firefox toolbar Prior to this, my old laptop would just use Outlook which was quicker/better.

The multi-step method using Mail was cumbersome so in trying to designate Outlook as the sending vehicle over Mail, I designated a non-performing solution which is now preventing me from emailing links (and captured webpage info) at all. I would like to migrate back to Mail or find the correct choice for Outlook but the "email a link to this page" in the Firefox toolbar does not work now as a result of my poor choice.

Anyone know how to fix this? I have "restored factory defaults" and other on the toolbar features but does not help. This was apparently an unrevocable choice.

I use a laptop with Fedora 36 installed. Firefox is version 104.0.1

Until a few days ago, there were no problems with video display. But since a few days, video content that is offered by the news site from NOS (Dutch television) is not displayed anymore. I only get this error: The media playback was aborted due to a corruption problem or because the media used features your browser did not support.

Also some content on Youtube aborts. For example loading https://www.youtube.com/watch?v=qq0BUiEs3JM results in this error: Er is een fout opgetreden. Probeer het later opnieuw. (Afspeel-ID: Ui0fzPxdSexgYcZ4).' (An error occured, try later again).

When using the Chrome Browser both websites can be used without giving errors implying that all the codecs are available.

How can I detect why video is blocked?

(Twitter also gives problems. After a fraction of a second, it stops displaying video)
