Hello there

I have a small NAS with various video files on it. Some AVI which work flawless but also some MOV which show but do not play audio.

Other chromium based Browsers manage to do so without any problems therefore it should be possible somehow.

Informations regarding the file: Filetype: MOV Codec: MP4 Base w/ AVC ext (ISO 144496-12:2005) Channels: 2 compressor: sowt Sample rate: 48khz Depth: 24bit Bit rate: 16

It was recorded with a Nikon D3200 camera.

As I am hosting these Files for other people I always get requests on why it does not work in Firefox.

I love Firefox and I want People to use it but such things just make in unnecessarly hard to do so.

I have experienced great business support from the Mozilla team, hope this to be true for home users too.

Thanks beforehand and have a nice evening.

Hi, I developed a simple Add-on, based on jQuery. Unfortzunately, it seems "ajaxStop()" does consistently not work as expected (at all). Any tips on what to consider to get ajaxStop to succesfully trigger my registered eventhandlers? Thanks

PS off topic: the "developer" area of Mozilla is quite painful to handle and reach. I'm always pushed/forwarded back over here. Also the sophisticated 2way-auth seems a bit overkill for posting on a forum .

I have tried everything and cannot manage to load any webpage that prompts a reCAPTCHA. The tab immediately crashes.

1- I've tried several webpages. They all work well until a reCAPTCHA pops up, the tab crashes and creates a dump file 2- I tried uninstalling Firefox, including erasing profiles and all Mozilla folders then reinstalling, and selecting refresh. It sill happens. No addons or extensions, and HW acceleration on and off 3- The problems goes away if I run Firefox on Troubleshooting Mode

Version is 94.0.2 (64 bit) running on Windows 10 21H1 on an i7 1165G7

Am I missing something? Is there a way to do a cleaner install?

Thanks for the help!

As the subject says, when attempting to upload images from my computer (Ubuntu 20.04 on Firefox 94), often but not always, the result will be a visual glitch similar to the image attached. The only time which I have ever used Zoom on Firefox, the same issue happened when I tried to use my webcam, except that the lines rapidly changed colours.

I apologize if this issue has been solved in another thread, but this is a bit hard to describe without the picture, so my attempts to search for said thread were unsuccessful.

The issue is not present when I upload the images in question via mobile. Turning off my extensions has no effect.

The image attached is taken directly from attempting to upload a profile picture to my Firefox account, but I have experienced this issue with websites like Twitter and Ebay for example. I have never had this issue with Imgur, for example, even though I am doing nothing different (uploading images). I do not know why this only occurs for a select few websites.

Any responses or help is appreciated!

When I try to post a pic on Marketplace in Firefox I select the .JPG picture and upload it. The picture I want to post appears fine before I upload it. Once I upload it to Facebook, it just appears as a solid colour. I have attached a couple pics, one is of the pic I want to upload and the other is the pic after it is uploaded. I should state that if I use Chrome or Edge, it works fine. And if I try to post a pic to my timeline it works fine. I just have this problem when using FireFox and trying to post to MarketPlace I know, well just use Chrome or Edge, I DON'T WANT TO :-) I want to use my FireFox. Ian

Have been trying to fix this problem - FF works beautifully if Kaspersky Internet Security is OFF but cannot access any websites when it is ON - just this PR_CONNECT_RESET_ERROR page.

Very slow site loading due to Windows Firewall.

Hello together.

I'm experiencing the same problem as discussed in this cases that is not solved yet: https://support.mozilla.org/en-US/questions/1312836 https://support.mozilla.org/en-US/questions/1333547 https://support.mozilla.org/en-US/questions/1321038

Symptoms: After FF starting it loads pages fast enough. After several minutes of using pages start be loading very slow. Loading slowness increases until it becomes blocked continuously. Reload button has no effect. I tried everything from here: https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - No effect.

Work around done: When windows is loading in Safe Mode the problem disappeared. If I disable Windows Defender Firewall the the problem disappear and appear after firewall enabling again in several minutes (same as after FF restarting) When I go to <current network settings> and switch Network Profile from Public to Private or from Private to Public the problem disappear but goes back just in several minutes (same as after FF restarting). Windows 10 Restorehealth has no effect, and reports that everything is OK with system files (DISM.exe /Online /Cleanup-image /Restorehealth ) The most strange thing Windows 10 In-place Upgrade has no effect.


I found out the core of problem is that Windows Firewall is blocking FF internal interprocess communication on local TCP ports. Yes, you would say it is not possible and firewall doesn't affect local port communication but in my case it is a fact. I used the ProcessMonitor from Windows Sysinternals, and Windows Defender Firewall with Advanced Security log. Screenshots shows this fact. On first two lines from Firewall log you see a Local Port Communication blocking, on ports 1401 and 1400. Next Screenshot from ProcessMonitor shows (see blue colored lines) that it was exactly FF communication, where I was trying to reload a page several times.

Any ideas what to do with it? It seems like Microsoft’s way fighting a concurrent web browsers, but I hope it isn’t.

Now I use FF version 94 but the problem starts from 88. I was trying FF downgrading to version 75 with no effect.

Yesterday afternoon I tried to watch a Netflix movie and the Error #F7121-3078 came up. It told me to update Firefox. I did to no avail. I then uninstalled Firefox and reinstalled...no luck. I have updated my Dell computer and ran my Mechanic Systems and still receive the same error. Everything else works fine. That includes the Google browser, You Tube, Amazon Prime etc., even the Netflix trailers. I chatted with Netflix and the young man asked a lot of questions but in the long run couldn't help me...What can I do that I haven't done already. Any suggestions???? Sally Negri

Several weeks ago, because it seemed to be a Gmail-tab-only problem, Firefox Support advised us to contact Gmail Support.

It is now clear that the problem is with the Firefox browser. The attached screenshot shows an example of an affected tab.

Please fix this. Multiple versions of the same tab waste RAM and other memory, especially on a limited-memory device such as a laptop.
