I access Bluesky (bsky.app) for business on my PC. Since the last update, I've been unable to access Bluesky from my regular Firefox browser. I can using other browsers, the mobile app, and, oddly, in Firefox private browsing. I've cleared my browser history, cookies, etc. I restarted the computer. I logged out of Bluesky (and now can't log back on the regular PC account because it claims I'm not connected to the internet). Yet, I had no trouble logging in using private browsing.

I've looked through settings, etc. and can't figure out what could be limiting my ability to access this website.

My mothers new phone won't load external links and mine does?

I have way more strict security settings and same extensions. She has 2 and I have 13 extensions but they overlap and are not the issue. When someone sends her a link her Firefox does not convert the link like mine does, she gets a link in format https://share.google/ + string of letters, when she opens it, it's a blank page. When I open the same link it converts it from that to a regular link (https://). I have installed Firefox to at least 3 other people and none have this issue. I don't have this issue on desktop either.

If it makes a difference: Out all the people that have this browser on their phone she's the only one that has a new phone with Android 16 (mine is Android 14). They are both up to date on both software and Firefox 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.

Firefox just updated, now getting ACCESS DENIED at common sites, Home Depot, JC Penney, American Airlines, United Airlines and I don't know how many more.

How do I fix this or go back to previous versions of Firefox?

Or just move to Google?

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.

After update, I am denied access to my Xfinity email account: You don't have permission to access "http://login.xfinity.com/login" on this server.

Why is Firefox blocking my access to certain form fields such as User ID, Email Address entry and Security question prompts to web accounts I have, such as a Rumpke payment portal? It blockeed my access so I cannot so you now for invalid tries because I could not key into them and locked me out of my account- sorry.

websites are being blocked when I click on links from my email account and I don't know why but I also want it stopped the websites are Stage32.com and https://course.fp-platform.online/learn/hRpTYcFi2UyZKzLm2gaOHg/theory

I have been placing a weekly online shop with Sainsbury for 10yrs+, on checkout their is redirect to my bank for authorisation of the amount. This hasn't worked since yesterday and after my third attempt today I noticed there was a message at top of page saying Firefox was blocking this redirect?? I haven't changed any settings recently so why is this suddenly happening?

I am a business owner and I need to log into united health care provider portal. Mozilla will not allow me to access. I'm using this link: https://secure.uhcprovider.com/ and Mozilla will not allow me to go further. This is causing work stoppage. Chat GPT says the link is secure. HELP! I need access so I can get paid.

From Chat GTP:

https://secure.uhcprovider.com/ I checked that exact URL, and here’s the key point:

👉 secure.uhcprovider.com is actually configured with HTTPS and a valid SSL certificate—so under normal conditions, your browser should show it as secure.

So if your browser is blocking it or labeling it “not secure,” the problem is almost certainly local (your device/network) rather than a new issue with UHC.

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 !!

Hi I have a couple of http only pages behind a VPN in a private network. When using Firefox for Android and entering the address, either with "http://" or no prefix, Firefox is not able to connect and instantly switches to "https://" mode. "HTTPS Only" mode is not activated, DNS-Over-TLS is also deactivated.

The page can be opened when using the IP address.

In private mode Firefox opens the page as expected.

All other apps on Android do not show this behaviour, i.e. Chrome for example opens the pages fine as expected.

With Firefox on Linux, it works fine.

How can I make sure that Firefox openes the HTTP page and not switch to HTTPS.

About:config is disabled in Firefox on Android so all tweaks changing the settings there do not work.

Tried this with and without plugins, no difference.

Today (4/27/2026) I am suddenly unable to log in to My Account on various websites (eMail, grocery store...) The business page opens but when I try to go to the account login page, I either get a blank page or the page spins and spins and never goes to the login page. I am able to get to the logins on Safari. I've cleared cache and cookies, and closed out of Firefox and reopened.

.

Firefox now blocks my email account... https://my.netzero.net/start/login.do I can log in through Microsoft Edge, however Firefox no longer allows this.
