i HAVE SET FIREFOX AS MY DEFAULT BROWSER, BUT WHEN I TRY TO OPEN IT MICROSOFT BING POPS UP. THIS INFURIATES ME AND I WANT TO KNOW HOW TO STOP IT. IN THE CONTROL PANEL IT WILL ALSO NOT ALLOW ME TO REMOVE MICROSOFT EDGE.

Would appreciate your help in advising how I can re-instate my Protonmail login as it just doesn't seem to want to let me access the site at all - it just tries to access and then keeps coming up with 'oops something went wrong'. It's like there is a block on letting me access? This has only just happened since doing firefox updates.

Firefox won't load google or youtube. In my gmail spam folder I keep getting emails stating "payment declined cloud storage full".

Ordered some new checks from Costco as a "guest" since I haven't set up an online account (generally speaking, I wouldn't use, but to order checks, I need to do it online - not in the store). I put my full order together in the cart, went through the full process of completing the order and payment, but after submitting, I expected the order confirmation page. However, I received the notice that the Harland Clarke check printing vendor site won't allow firefox to display the page. Without that confirmation page, I don't have an order number to reference. The instructions provided says to embed the link (which link?) in another tab to open the missing page. I've also tried following all other instructions; going on the Mozilla/Firefox desktop/ trying to find a Mozilla contact phone number, etc. All that happens is that I go into a never-ending circle - which means no-where. What am I missing? This is what I get:

Fix error “Website will not allow Firefox to display the page.” 3–4 minutes

Some websites don’t allow their content to appear inside another website. If a site tries to embed a page that blocks this, Firefox will show an error that it cannot open the page:

“To protect your security, [website] will not allow Firefox to display the page if another site has embedded it.”

This is a security feature on the website being embedded. It prevents clickjacking, where a site tries to load another site without permission, often to trick users into clicking something they didn’t intend.

This error is not caused by Firefox. It’s a choice made by the website owner. Why does this happen?

Websites can control how their content is used. They may block it from being shown inside another site using special security settings like:

   X-Frame options headers
   Content security policy rules 

These settings are common for banking sites, schools, government services and others that need tight security. What can I do?

You can still view the blocked content by opening it directly. On desktop

   Right-click the link or embedded area.
   Select Open Link in New Tab or Open Link in New Window.
   If you can’t right-click, try copying the link (long-press on Mac trackpads) and pasting it into a new tab. 

Tip: You can also drag the link into a new tab if using Firefox on desktop. On mobile (phone or tablet)

   Tap and hold the link or embedded area (where the content should appear).
   Choose Open in New Tab from the menu.
   If that doesn’t work, try copying the link (if visible) and pasting it into a new tab manually. 

Warning: On mobile, this may be harder to do if the embedded content doesn’t show clearly. Look for a blank or gray box on the page. What if I need to use the original page?

Sometimes the website that’s embedding the content depends on that embedded page to work properly (for example, a school login system or internal portal).

If that’s the case:

   Try opening the embedded page directly (as described above).
   If that doesn’t help, you may need to contact the site owner and explain the issue. 

Need help understanding this error?

If you're unsure what the page is trying to load or can’t figure out where to click:

   Look for a blank box or missing content; that’s likely where the blocked page should appear.
   If you're on mobile, try rotating your device or zooming out to better view hidden content.
   Still stuck? Copy the page link and share it with your IT support, teacher or website admin.

Any ideas why & a fix much appreciated :)

Edge" (or some Microsoft product) repeatedly tries to preempt Firefox, my default browser, loading my default page: Yahoo.mail. It happens inconsistently, and in different manners, hard to describe. It happened on my desktop and also on my laptop. It seems very aggressive, but right now the start-up was normal

I was denied access to Costco website online for certain services??

Please do advise. Thanks.....

I cannot sign into Discover Card when I use FireFox. I talked to Discover Card about it. They say the most frequent reason it happens is because Discover Card is not on your safe list. I tried signing in on my other PCs with a Ubuntu OS and their browser Opera works fine on signing me in. Within the last two weeks I installed Mint on two of my PCs. works great except for not being able to sign in to Discover Card. I am not having that problem on any other sites. I doubt if my cache is full as my usage being new OS has been minimal. I just tried signiing in with this PC after installing Mint yesterday. I get the same message

"We're sorry. Your request cannot be completed at this time. We sincerely apologize for this inconvenience and are working to resolve this issue soon."

Discover wants to blame Firefox. Personally I think It has to do within the Mozilla VPN. I say that because I often had the same problem when I used McAfee's VPN. Discover maintains it has nothing to do with VPNs and it is a trust issue.

Eventually I want to replace Ubuntu with Mint. But I cannot until this problem is fixed. Opera is also running a VPN when I sign in so this would support Discover Cards theory about Firefox not having Discover on a safe list. I think they have it wrong though. If your site is blocked you are not on Discover's safe list. I wish we could get a meeting of the two minds instead of me trapped in the middle. Hope this helps.

I can't get into my Yahoo Email account, and keep getting, 'try again' which I've done repeatedly, then 'check internet connection' which seems to be fine, then to 'make sure Fox Fire has permission to enter', which until today I've thought they have always had because I've never had this problem before, so what could problem be today, and how do I fix it?
