Firefox Community Forum

I am trying to access certain HTTPS websites and some of them show PR_CONNECT_RESET_ERROR in Firefox. This error is not present in Edge or Chromium.

Here's what I've tried (none of these works):

• DNS over HTTPS turned off
• Uninstall all add-ons
• Reinstall Firefox
• Create new profile and set it as default
• Delete/rename certs.db in the Firefox profiles folder.

The only fix that works is to use Troubleshoot Mode every time I visit these websites which is not practical. Any ideas on what could be the problem?

I don't know if this is relevant but one of the websites that does not work is https://alexan.com.ph/

With Firefox 135.0 i cant reach google.com but google.se i can.

I make daily images of C: and today i managed to go back one day to 2025-02-06 but accidentally chooses 2025-01-06 and with the older version of firefox i could reach google.com

I have tried to delete cookies. DNS over HTTPS off. No proxy in connection. Add-ons off but to no avail.

In Firefox, and only in Firefox, I get 'Failed to verify your identity' on these sites. I have updated MacOS and Firefox, rebooted, tried a different DNS, and disabled all of my extensions. With extensions disabled I don't get the error, but the login site won't accept my login at all. See the attached image. I can't think of anything else to try.

The font size in "Manage Bookmarks" is way too large, both in the sections list menu on the left and the list of bookmarks. I checked my userChrome.css file as well as the layout.css.devPixelsPerPx entry in about:config and there's nothing there to explain why only the "Manage Bookmarks" text is so large.

It's possible I changed a setting somewhere that's causing this. But I'm stumped re: what setting might be controlling the font size in only that UI. All other Firefox text sizes are good.

Thanks to anyone who knows where I should be looking

Firefox 134.0.1 (64-bit) Windows 10

https://read.amazon.com/kindle-library is now not allowing me to go onto the website. I've tried talking to Amazon customer support but they can't find a problem on their end. It says:

The connection has timed out

The server at read.amazon.com is taking too long to respond.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

I haven't had a problem with the website before and every other website I have tried works fine. It's just that one. I have added it to my exceptions list for add ons but it didn't fix it.

Current Behavior When Firefox is set to offline mode (File → Work Offline), the Developer Tools Network tab does not display request body of requests that web applications attempt to make. This creates a significant gap in debugging capabilities, as developers cannot inspect request payloads details that would normally be visible.

Requested Enhancement Enable the Network tab to capture and display attempted network requests payload even when offline mode is enabled

i have problem with setting up my proxy. i choose manual proxy configuration, fill the HTTP Proxy & port. When i click ok then input username & password but it keep asking for the username & password. (I have asked the proxy provider they say the proxy is good, no problem)

Hmm. We’re having trouble finding that site.

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

I know little to nothing about computers. My Mozilla account says it is disconnected whenever I come online. I do not manually disconnect ever. Keeps telling me that it cannot detect proxy even though my proxies are set to off.

I travel to two different locations a few times a year. I use the same basic "computer" for each one, though they're far apart. It works through a "sneaker network," where data files, profiles, etc, are copied to a portable hard drive and then copied to the next computer, so they're fairly identical.

The problem is that this last time (and I've been doing this for perhaps about 3 years), Firefox has refused to do anything online. I can use it offline, but not online. The "work online" is unchecked, so it should be online. But it refuses to do anything.

After several Firefox reboots, windows reboots, checking everything, Firefox still does nothing.

Currently I'm using Waterfox and Edge. Both work fine. Thunderbird works fine.

I've had this problem since Tuesday night. So about 48 hours now, and nothing at all.

The way I transfer from one computer to another without losing email or current Firefox status is to copy the newest profile over, delete the old, and then copy the current program, as well.

Thus, the program is up to date, as is the profile, but all I get when I type in any address is that dot thing at the top, going side to side.

Thank you in advance.

When I click on Firefox and the to my email it says there is a problem with my internet. My internet is up and running fine. I have done everything it says Firefox can't connect to the server at mail.yahoo.com.
