Firefox Community Forum

I run the current version of Firefox (152.01) under Windows 11 Pro on a Dell Inspiron 15-3530 laptop. More and more frequently, I'm getting "Access Denied" messages when I click on a site link t56o an internal page. This happens on several sites, most notably Dell.com. I get the error in Troubleshooting Mode, and clearing the cache doesn't help. I've searched the information here, but all the responses seem to involve Windows 7 or Windows 8, not Windows 11. Can someone tell me how to resolve this situation in Windows 11?

Thank you.

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.

I am unable to load my Facebook . have Googled the problem but am anable to perform most of their advice. I am running W11 and have emptied the cache but this didn't fix the problem. Please help !!

Just seemingly out of the blue I started getting Firefox captive portal warnings. Most websites load normally but if it's a new site i.e. one I ahven't visited in a while I get the "you must log into this netrwork before you an access the internet" message. I am and have only and always been on my home wifi with this computer, it's a laptop but has never been out of my house. Forefox seems slow lately and I keep getting this message. Other browsers work fine by the way.

recently when trying to book a flight on American airlines i get a "not authorized to access the server". No problem logging in. has been happening on other web sites as well. seems somewhat random.

Hi, I'm using Firefox on Desktop and Mobile. For last couple of months, I've been experiencing a problem of Shopify stores loading. When we open any Shopity website (stores specifically), it never loads. Sometimes it shows blank page and sometimes nothing.

At the same time, those sites are working fine in other browsers e.g. Chrome, Safari.

However, when I switch to other wifi network (jazz.com.pk), then it works on Firefox too. I tried different methods to fix it, but no success. Before the websites were sometime opening, but for lost few days, 0 response.

Not sure, where is this issue, I contacted my network support (nayatel.com), they also unable to figure it out.

I tried everything on my end, but no success. Need your help.

I got to PIA's website, i navigate to the download vpn section and from there, firefox blocks the connection and says the server is offline, Ive just done this chrome and edge with no issue, my issue is that its not only this site itll do this on.

I turn that off and still no Twitter and your system turns it back on again all by itself, your settings are doing what they want to do, not what I SAY to do. Now, I cannot get into Twitter.

it is obvious your system has changed: I have windows 11....the help I see is for windows 10

where are the current updates?

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.

I cant use firefox to connect to mail.com. I can connect by other browsers just not with firefox. Server Not Found
