Firefox Support Forum

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.

Hello, i have run Firefox for years on 2 separate computers each with their own data and now I want to sync them. My problem is I don't understand to the 2 different sets of data if I sync. Do the 2 sets 'blend' somehow? Does one set take primacy over the other (if so, how do I control which one it is?) or do I lose everything from both computers and start again? I've been wanting to sync for 12 months but I am so scared of losing information that I keep avoiding doing anything. Thanks Chris

I have lost recent activity on home screen. There are blank tiles but nothing is being added.Hovering over tiles nothing happens. How do I get recent activity to appear again ?

So I've recently shifted from Chrome to Firefox and there's his specific touch pad gesture I set up on windows settings and it acts like media controls, but it seem to be unresponsive. Tried it with Chrome and VLC media player and it worked normally. Tried setting about:config; media.hardwaremediakeys.enabled but its already set to true.

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

I have several virtual desktops: Desktop 1, 2, 3 and 4. Case 1: Assume that there is at least one opening Firefox window in any virtual desktop. And, if I try to open a new window in Desktop x (x = 1, ..., 4), it will appears in Desktop x as expected. Case 2: Assume that there are currently no opening Firefox windows in any virtual desktop. And, if I try to open a new window in Desktop 2 or 3 or 4, it will only appears in Desktop 1.

Hello everyone!!

I've been experiencing a rather "unusual" issue: My Firefox up until version 116.0b8 worked perfectly fine; however, after any updates to versions beyond that, it stopped working.

I've tried the final versions and the betas, but nothing works. I attempted reinstallation and everything else, but I couldn't solve the mystery and remain stuck on version 116.0 beta 8.

What's happening? Every time I try to load a page on any version above 116.0, it either doesn't open or keeps loading in a loop. Yet, if I use another browser or revert to version 116, everything works correctly. This issue does not occurs in others machines.

Has anyone experienced something similar?

Thanks in advance for your help.

Dear FireFox, I am writing this E-mail to address a critical issue. So i wanted to set up a password for my firefox browser so that only I can access it. i set a primary password, and it asks me to enter the password when i open my browser. However, when the message appears asking me to enter the password, you can just click "cancel" option or press 'x' it ignores the password and lets me in the browser, essentially rendering the purpose of the password useless. thus anyone can access my browser. i request you to fix this problem. Regards -SpideyKnight

I've noticed that Firefox has been running very slowly on my computer recently. Pages take a long time to load, and the browser often freezes or becomes unresponsive. I've already tried clearing the cache and disabling extensions, but the problem persists. I'm using the latest version of Firefox on Windows 10. Are there any other troubleshooting steps I can take to improve performance for my website?

1. In the past there was a restriction on the suggested number for "network.http.max-persistent-connections-per-server". Is that still the case?

2. Does prefs.js contain all the altered about:config settings? Can I safely transfer "prefs.js" to other profiles in attempt to enable all those settings changes, instead of changing them manually, one by one.

For several months, Firefox has been unable to play videos from various different websites, including Netflix, Paramount Plus, Youtube, and others. I've turn off VPNS, reset my internet router countless times, cleared cache/cookies, flushed DNS, updated firefox, updated my video drivers, updated windows, disabled extensions (including adblock), opened Firefox in safemode, and reset hardware acceleration. This is not an issue on chrome or edge. Some of the error messages include: Netflix F7351, Paramount Plus 5000, and error code 102630. Youtube mostly doesn't work on livestreams, and says that my browser isn't compatible.

This started a week or two ago intermittantly on some websites. Today I cannot see any images of amazon items in the shopping cart. I can see the thumbnails in the right side bar, and if I click on an item, the image appears on its for sale page. Ebay usually shows the first image, but the rest won't load, unless I click on "unable to load images" and then they might. Or if I use the icon to put the images in their own box, I can < and > to navigate them

Turned the new "secure DNS" feature off & on, no difference. Turned off NoScript, no difference.

My laptop glitched while doing a Windows update and it chose to not load certain apps upon completing the update. Mozilla Firefox was one of the apps it chose to delete and I lost all my bookmarks with my login information to all my accounts, can I retrieve those?
