PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

This error occurs constantly on Firefox. I've had to go to Chrome to connect. I want to use Firefox, but not if it keeps doing this.

I am repeatedly getting this pop up window after starting my computer and selecting the Firefox icon in the toolbar to start the browser. When using the Firefox browser I always update Firefox when prompted, so it should be the latest version, unlike what it states in the popup window. If I want to use the browser, I have to sign in to the browser and sync my data and I have to re load all my tabs from my history. It is time consuming to the point where my colleagues who were using Firefox have uninstalled Firefox and are now using a different browser. I could do the same...but I want a solution. I'm using Windows 11.

Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

Is there anyway to force actual mozilla pages to be displayed in a dark mode instead of the blinding white background that hurts my eyes to view ? Thanks, David

Hello,

For a few days now I've been unable to use Google tools via Firefox (I can't tell if this is due to an update or not).

As soon as a document (usually an editable or navigable area) is opened on the page, it appears completely black. Interactions work correctly at first glance (it's possible to click, write, interact with content that isn't displayed. The problem seems to be purely visual.

I've encountered the problem in all Google Sheet or Docs documents (including when I'm making a new one) and on Google Maps, regardless of location (in the case of Google maps, a notable point is that the map is displayed and then turns black after one or two seconds).

I don't have this problem on another browser, I have it in PM.

Do you have any ideas on how to find the cause and fix the problem?

Have a nice day!

I can not get Youtube to load on desktop Firefox. It works fine on the mobile website, app, and Chrome. I've tried clearing cookies and site data, removing extensions, resetting Firefox, and disabling hardware acceleration, and so far nothing has worked. Has this been happening to anyone else ?

I want Protonmail as my default mail for Firefox. Windows 11 allows me to install Protonmail as an application. I cannot find or use that application in order to use my Protonmail email as my 'mailto' option in Firefox. Why does Firefox not allow this? Why can't Firefox find and suggest the Windows 11 Protonmail app in its list of suggestions under 'mailto' options?

I had a Firefox account on my phone. I got hacked. So I uninstalled the Firefox app. I got the upgrade for Lookout and added that to my phone. I opened a new Firefox browser on my PC because I was tired of Google and I don't like Bing. I think you are still using my phone account. dawniegirl1973. lt has never been a primary or secondary email for phone or Pc. But you caught the last hacker! I would like an upgrade with Firefox on both PC and phone if I wouldn't have to pay for both devices. Would that cover both PC and phone? They are not linked, but they do share 2 emails and passwords. I also would like VPN, if that would secure my wifi. But I need a network that I can use for all my internet needs. I don't know what all VPN does. Please help me out. I don't know what to do anymore. It's all gotten so confusing. I'm tired of being hacked. Please advice. I trust, you, Firefox and I want you on both devices can we do this?

I downloaded a large filed in my Firefox Browser and it took me 2 days to download the file but when it's almost done, it suddenly failed download. Can you help me resume the download? I think it stopped around 60 gig.

I like to clear the cache on a regular basis but then Facebook does not recognize my laptop and I have trouble logging back on. Is it possible to clear the cache for all but a select website? Thanks

For some reason I looked into whether my Firefoxes are ever using HTTP/3 - turns out they aren't. I looked up how to get any kind of information on this, and saved networking logs. They indicate that the moment Firefox tries to send the first UDP packet for the HTTP/3 connection, it gets "ErrorAccordingToNSPR [in=-5987 out=80004005]", the connection fails, and the server is added to an exclusion list so that no further (futile) attempts at using HTTP/3 will be made (which makes reattempting a HTTP/3 connection by hand that much harder). The initial platform was Windows 11, with Firefox 98.0.2, but afterwards I reproduced the issue on another PC running Windows 10, and with a nightly version on Windows 11, which I also used to save some logs which I can publish, as they don't reveal the sites I visit (though I can always provide the logs from my everyday instance of Firefox, should you find the information insufficient).

I also confirmed that HTTP/3 works with Chromium on the very same system and network, and also with Firefox on another machine running Linux.

For the past several months, I've had increasingly worse graphical errors on Google Drive. At first it was only in a few documents, and now it's in every single document. These errors only occur on Firefox, no other browser. Text that I type is constantly blurry, oddly-sized, or oddly-spaced, with some letters touching while others have large gaps between them. I've also had some other small issues, like the document thinking that I'm two people and asking me if I want to see "the changes made my collaborators" when I'm the one currently typing (the documents aren't shared with anyone else, and there are never any changes beyond the ones I make), or showing my cursor highlighted with my name as if I were someone else watching myself type. It's made it more difficult for me to focus on work and I don't know what to do about it.

I've tried the following methods (most of them multiple times over the past months) to solve it, none of which worked: - Running the windows in safe mode - Uninstalling all add-ons and themes, clearing cookies and cache, and then restarting my computer - Uninstalling Firefox entirely, restarting my computer, then reinstalling it - Refreshing Firefox - Looking through pages like Firefox Task Manager and such (although the information there didn't really mean much to me, nothing looked out of the ordinary)

Does anyone have any ideas about what I can do about this? I was ignoring it for a while since it's still legible, but it's become really annoying, especially when it makes some words hard to read. Thanks in advance for the consideration. Here's a screenshot of a document with the weirdly-spaced, blurry text:

I am encountering an issue where I am unable to update from within my browser (Help->About). I have confirmed that the policies.json ("C:\Program Files\Mozilla Firefox\distribution\policies.json") has "DisableAppUpdate": false, to ensure I am not blocking myself. As of now if I try to update it gives me a prompt saying: "Updates avaliable at https://www.mozilla.org/en-US/firefox/new" Is I give myself administrator access then I get normal behavior and the browser begins updating automatically.

The odd thing is if I modify the permissions on C:\Program Files\Mozilla Firefox directory to allow normal users the ability to write/modify its contents then the Normal User Account is then able to update the browser as desired. The obviously solution is to just modify the permission and allow Normal Users to update. But I am hoping you have a better solution that more precise because I am concerned of the security impact of opening the directory to all users.

Is there a specific file/sub directory I can give them access to that accomplishes the same thing or is there a setting I need to change on the installer that would fix this.

Thanks!

I have at least one extension that has had a later version than what I have for days and firefox is not updating it even though everything is set to auto-update. i hate to have to uninstall/reinstall it since I will lose all the settings I have in place. Any ideas?

The developer says firefox is just waaay behind on extension updates and it isn't their fault.

I travel for work and often stay at IHG properties (Holiday Inn, etc.). I have Firefox as my default browser; version 99.0. I cannot login to their wifi using Firefox; I have to copy the address and paste it into Google Chrome and after confirming my information I am able to browse normally until the next day; It must reset at some point.

This is the web address for the network login: https://www.msftconnecttest.com/redirect

I read this article about Captive portal detection: https://support.mozilla.org/en-US/questions/1314194 I change the setting per the article hoping it would take care of my concern but it did not.

Thank you!

New computer, running Windows 11, McAfee LiveSafe came with for 30 day trial. I use Firefox, have since 1997. Just added Mozilla VPN. Old computer ran Xubuntu. Windows 11 needs antivirus because it's Windows. So. How compatible are McAfee LiveSafe and Firefox with Mozilla VPN? What suggestion, if any, does Mozilla have for an antivirus program that will work well for Windows 11 but not mess with Firefox and Mozilla VPN? Thank you.
