Diễn đàn hỗ trợ Firefox

Hello- about 6 or 7 months ago I started noticing issues where I will type in a web address or a search term and it will not do anything after pressing enter. Just sit there blank. This does not happen all the time but is happening enough that it is frustrating. for example I could type in bank of america or amazon.com or something like that and it will not do anything. No spinning wheel no anything. I can delete what I typed in and try typing something else and the same thing. I can open a new window and try searching again and it will do the same thing. Then a few minutes later I can try it again and it will work fine. BUT what DOES work always is if I open a new private window and search that way it will always work.

Any thoughts? i've deleted cache/browser history, cookies, un-installed and re-installed. I have the firefox is up to date message. I am using FIrefox 151.0.3 64 bit Using windows 11 Home version 25H2

I use Google as my default search engine in firefox.

Thanks

Ryan

when accessing websites where Cloudfare is part of the sequence the page hangs on cloudfare and the page is not displayed. Every time data is transferred through cloudfare the page hangs on cloudfare rending the search useless.

'bold text' It will not allow me to go past the home page on large sites such as www.homedepot.com or www.costco.com . I get the following notification.

Access Denied You don't have permission to access "http://www.costco.com/gasoline.html" on this server.

Hi,I am trying to open my Hollywoodbets account in the Mozilla Browser on this Device which I am currently using,but can’t seem to open the Hollywoodbets web page.Please I need assistance.

I edit a newsletter substack and sometimes I have links embedded in it. Mozilla denies me access to those links when I check the newsletter. Do I have to cancell Mozilla protection to have full access to the links in my newsletter from substack?

I keep getting this message:

Firefox Can’t Open This Page

To protect your security, login.microsoftonline.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. What can you do about it?

I can't open the link in a new window as I have to click on a tab and when I right click on the tab it only gives the pop up box that says "take a screen shot" etc.

I tried "allowing" the website for pop-ups but it still didn't work. I don't know what to do now.

Hi everyone,

I'm having trouble accessing my local network devices (a 3D printer and Raspberry Pi) using short hostnames like "http://impressora3d" or "http://impressora3d/". Firefox keeps blocking the connection with the "Looks like there’s a problem with this site" error page.

I've captured a network log using 'about:networking' and I can see that: 1. DNS resolution works perfectly and points to my local IP:

  "CompleteLookup: impressora3d has 192.168.1.10"

2. Firefox is upgrading the request to HTTPS (port 443) automatically:

  "nsSocketTransport::ResolveHost [...] impressora3d:443" -> "pushing io layer [0:ssl]"

3. The device rejects it because it only listens on HTTP (port 80):

  "Bad Socket 804b000d" (NS_ERROR_CONNECTION_REFUSED)

What I have already tried: - Disabled "HTTPS-Only Mode" entirely in settings. - Checked "Secure DNS" (DoH) settings (set to Increased Protection and added exceptions). - Cleared history and used "Forget about this site" on the hostname. - Typed "http://" explicitly.

Firefox still refuses to connect via plain HTTP (port 80). Is there any hidden 'about:config' preference or HSTS cache forcing this behavior for local unformatted domains?

Thank you!

Something is wrong with your network configuration We checked your network configuration and found that the following domains are not accessible.

You block me when I want to open deposifiles.com I trust that site and have used it for many years. Stop this blocking action please.
