Firefox Community Forum

I use Stockhouse.com as a homepage and when I opened my computer this a.m. the site came up and it asked me to sign in which it normally does these days and I click on sign in and it shows my email and password and I click again and I'm signed in. This morning it asked me to provide my email address and password i.e. fill in the blanks. It has not done that for at least 15 - 20 years. Not remembering offhand what my password was I clicked on the 3 line application tab in the top right hand of my screen and brought up the list which includes "Passwords". I clicked on the password file and it is blank. It has never been blank before -- did Mozilla/Firefox make a change that would make my password file disappear?

I use siscom.net for my emails. The pointer doesn't seem to open the emails. It changes into a finger on a hand and doesn't trigger the opening of the emails. I'm using Windows 11.

Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

I have no issue with youtube on any other browser, but I do prefer Firefox. However, Fierfox says that site is slowing down firefox and suggests I close that page. Firefox did not do this in the past. Is this similar to the rather ugly color of the private window that I can't change, not being a coder? The impression I get is that Mozilla is making changes without assuring they work properly. I currently have to use chrome to make sure youtube works correctly.

New OS LMDE7 (trixie debian 13 base) Installed Firefox from the Mozilla Firefox Debian Package mozilla-debian- 1.0 Firefox 148.0

I've just installed LMDE7 alongside LMDE6 and want to move the 6 profile into 7. I've exported the 6 profile into backup and then moved it into the new Firefox Home folder (\home\...\.config\mozilla\firefox) Found both profile.in and installs.ini there AND many different profiles. (I had tried to use the profile manager and seem to have created lots of profiles beside the default-release from 7. Installs.ini shows both the original profile from the 7 install and one created with the Profile Manager and both are locked. They are also in profile.ini as installed.

So my Question is how do I install the old profile into profile.ini?

v148, Win 10

The site froze while playing a video. It happened multiple times. Is anyone else reporting this kind of behavior on Instagram. I closed the tab, but cpu stress-like side effects remained for a while.

I have a problem trying to get the app PC Express past the sign in. The app is part of the yourindependentgrocer.ca app. I have used Firefox, Chrome and Edge and have encountered the same problem. I use Proton for my e-mail and I have used all their apps for my computer. I recently changed the start up app from judymk@protonmail.com to judymk@pm.me. I don't think this is a problem as Proton says the app should not care what protocol is used as it translates the same regardless of what app is used. I would appreciate any help with this.

My Firefox shortcuts keep disappearing: this is an almost daily occurrence. Sometimes they re-appear later without any intervention, sometimes they re-appear after a reboot. Right now, after rebooting and 'fixing' Firefox from Control Panel, they are still missing. I have 4 rows configured for both shortcuts and recent sites, and had 'pinned' about 20 shortcuts. Currently on Windows 10, soon to upgrade to Windows 11.

Can someone PLEASE tell me if there is a fix available for this (will it be resolved in Win 11?), or if there is a way to easily save and restore these backups when this problem occurs.

The ability to have 32 shortcuts is the motivating reason for my using Firefox over Chrome or Edge (which only allow 8), but if they keep disappearing like this I'm going to have to re-think my browser selection.

Thanks for any suggestions.

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

Windows10 simply multiplies the numbers of active Mozilla Firefox Apps which are open. Every day for about two weeks I've been having to delete hundreds of Firefox Apps open in the Task Manager. So many open in a very short time it locks up the Win10 system. I've attached a pic

Win10 will no longer let me download & transmit a .jpg file, sorry

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

Firefox, Firefox for Android Firefox, Firefox for Android Last updated: 8/24/25 36% of users voted this helpful

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.

Firefox memorizes userIDs and I do not see an option to stop it from doing so. Is there an option?

Keep in mind that passwords are not limited to the password entry. Every entry in a sign-in process is an opportunity for a password. For example, the answer to "What street did you grow up on?" could be "Beatlejoice". Similarly, the answer to "What was your mother's middle name?" could be "Aardvark". Nonsensical answers to security questions are more secure than truthful answers.

Again, in the interest of security, is there an option to stop firefox from remembering so much?

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:
