Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

When I try to open Firefox I am getting this error message: Error: platform version '124.0.1' is not compatible with minVersion >= 124.0 maxVersion <= 124.0. Does anyone know how I can fix this? Deb PS I need simple instructions, I'm not terrible techy.

I used to be able to press Enter in the empty Firefox search bar to bring up the (DuckDuckGo) search page and enter my search from there. Don't ask me why I like doing that, but now after the latest Firefox update, 128.0, on my MacBook Air I can't do that anymore. I have to type in the search bar to bring up the search page.

I know it's a small thing but I wonder if it can be put back to the way it used to be.

I have been unable to connect to any website through firefox. Every other browser works. Can someone please help?

The error is:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.google.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

For the past few days when I have tried to log into a few websites which use TLS/SSL I have gotten PR_CONNECT_RESET_ERROR. Please see the attached screenshot for more details. This issue was observed ever since I updated to Firefox version 124.x. Prior to that the websites were working fine.

When I try to access the same websites and try to log into them using Microsoft Edge, I do not face a similar issue. They work fine.

I have cleared the browser cache, restarted firefox, and then tried. Still faced the same issue. I have cleared the DNS cache of Firefox browser (about:networking#dns) and then tried. Still faced the same issue. I have opened Firefox in Safe mode (Menu > Help > Troubleshooting mode) and still faced the same issue.

Can someone please help me in fixing the issue? I would like to refrain from using MS Edge or chrome browser.

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help

Hello. Since re-installing ZoneAlarm Security Suite (due to a ZA problem) last evening, after I turned on my pc today I am getting a new tab opens up on every FireFox browser window seeking permissions for "Harmony Web Protection Privacy Policy". (There are four new tabs for that which have opened since I commenced typing this!).

Is this a ZA problem or a Firefox problem? Also, please, how do I get rid of these damned new tabs? TIA.

Websites look extremely ugly because of the white borders surrounding icons. I've tried using CSS code I found on Reddit from posts that - I think - are related to my issue, but they proved fruitless.

What CSS/Setting do I have to disable to get rid of this?

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

aur/ffmpeg-compat-54 1.2.12-4 (+87 0.00)

   Compatibility package for ffmpeg to provide versions 54 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

Lately YouTube playing videos have been playing super fast or skipping straight to the end. I mean, they are horribly fast.

Things to know:

• I am posting here because I can't determine whether browsers may have settings unique to them that I need to change. This also happens in Chrome, but not Edge.
• I was recently forced to upgrade to Windows 11 - I can't say this issue happened exactly at that time, but fairly recently after the upgrade. I am running Windows 11 Pro.
• This does NOT happen when playing in a private browser window, either Firefox or Chrome.
• Having the Mozilla VPN on or off has no effect.
• I am sure the playback speed is set to normal. I have tried changing the playback speed to anything but normal and then back to normal and the current video runs correctly UNTIL I play the next video.
• This does not happen with Vimeo.
• It does not happen in FF for Android.

Any questions, thoughts, or advice would be appreciated.

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

Recaptcha isn't working in Firefox. It works in Chrome, Opera, and Edge with no issues, it will either just go to a check mark or open the window with the pictures to choose, on both regular pages and on the Google Recaptcha Demo site Google Recaptcha Demo site. But when I load a page that requires Recaptcha in Firefox, it just spins forever. It was working fine a few hours ago, and I didn't change any settings or anything in Firefox. I was filling out a job application and it worked fine, then I went to another job application and Recaptcha won't work at all, even on the Recaptcha Demo site.

I'm on version 125.0.3 (64-bit), on Windows 10. Not using a VPN or anything like that, just a standard Ethernet connection, with whatever Charter gives me.

Steps I've tried, none of which have helped:

1. Cleared Cookies. 2. Restart Browser. 3. Restart Computer. 4. Restart Modem and Router. 5. Opening Firefox in troubleshooting mode. 6. Ensured Firefox was up to date. 7. Reinstalling Firefox. 8. Turned Connection Settings to no proxy. 9. Turned off Enhanced Tracking Protection. (It's set on standard otherwise, and I didn't change it) 10. Release/Renew IP via Command Prompt.

I'm genuinely at a loss of what to do, after a couple of hours of searching around for solutions. I don't get how it just stopped working in the span of like ten minutes when I didn't change any settings or anything. Firefox is my main browser and it would be a tremendous pain to have to use another browser for any pages that require Recaptcha.

Any assistance or advice to solve this problem would be greatly appreciated!

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Just in the last few weeks, "buttons" on web sites do not work in Firefox, but work fine in Chrome. Example: https://www.mealtrain.com/users/sign_in/ The sign-in button does nothing in Firefox, yet works fine in Chrome. V. 125.0.3, Windows 10.

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

When i click on a tab, if I am not perfectly steady at the time of the click, Firefox opens the tab in a new windows. It happens several times a day, it's quite annoying. Searching for solutions in the support page, I've found that there was an add-on to disable this function, but now it's not available anymore. Is there a solution in 2024?
