It seems that Firefox has been erased from my Windows 11. I need to get Firefox back into my Windows 11. There is nothing I did to cause FF to be erased. Windows had an update and after that the FF was gone.

I am watching a movie and would like to use Picture-in-Picture mode so I can continue watching while working, thanks to its floating window feature. However, I can no longer use it.

I have already tried clicking the Picture-in-Picture icon on the video, using the Ctrl + Shift + ] shortcut, and verifying that the feature is enabled under Settings > Tabs and Browsing > Media. Unfortunately, none of these methods worked.

I would appreciate it if you could help me resolve this issue as soon as possible. Aside from its extension support, Picture-in-Picture is one of the main reasons I chose Mozilla Firefox.

Thank you in advance for your assistance.

Sometimes, for no apparent reason, on my Win 11 ASUS laptop, Firefox will suddenly use a lot of resources, such that the temperature jumps from about 50 degrees to 95 degrees and the fan runs full speed. It appears the only way to stop it, is to close FF then reopen. What might cause that?

I also have an unanswered previous question about being unable to pay accounts.

Cheers, Keith

Dear Customer Service Team, I am writing to request a refund for my monthly subscription fee for the product Mozilla VPN, in accordance with your 30-day money-back guarantee. Unfortunately, the subscription (from 18th July 2026) did not meet my expectations, and I would therefore like to make use of this guarantee and cancel my membership. Could you please confirm the cancellation and process the refund to my original payment method at your earliest convenience? Thank you for your understanding and assistance.

Best regards, Lorenz Claus

Hello there,

I’m experiencing high memory and CPU usage in Firefox, which is affecting my computer’s performance. One issue appears to be that “FirefoxCP Isolated Web Content” continues running even when tabs are inactive, contributing to increased resource usage.

Other browsers, such as Microsoft Edge, reduce memory and energy consumption by putting inactive tabs into sleep mode after a period of inactivity. I would prefer to continue using Firefox as my default browser, but I need a way to manage this level of resource usage.

Could you please advise whether Firefox offers a comparable setting, workaround, or planned improvement to reduce CPU and memory usage from inactive tabs?

Thanks for your help!

When I try to enter the VA site (https://www.va.gov/my-health) it never opens (see attachment). I use my back-up browse (Microsoft Edge) and I can enter the site. Can you help?

My folders suddenly stopped loading. When I log in, I can see grey boxes down the left hand side where my folders used to be. It looks as if the folders are trying to load, then the grey boxes disappear and all I see is in the screenshot I have attached.

I have followed the instructions GMX provides. Cleared the cache, etc. Those didn't solve the problem. The second attachment shows instructions that showed when I did an online search. Please ignore the second suggestion regarding Thunderbird. If these instructions refer to gmx settings, I cannot access them as you see by the first attachment, there is no way I can access gmx settings. The icons you can see only change how my inbox contents are displayed. If the instructions refer to email settings within FIREFOX, I am still stuck as I can find no help within FIREFOX on GMX settings that deal with these settings. I am offering my firstborn, my beloved dog, Reggie, and my best wishes for a long and happy life to the person who can successfully help me with this problem. Hopefully, Pam Barkas

Cant access "X" website .... get message that says Firefox's Enhanced Tracking Protection (strict mode) is known to cause issues on X.com

Using the "re-open tab" function on a browser based discord instance changed a bunch of my settings, for one it turned on vertical tabs, added extra side bars to everything, and made every ui element animated. Ive figured out of how turn vertical tabs back off, and while I was writing this, I figured out where to turn off this stupid animated gizmo to select what I actually want, instead of directly bringing up my bookmarks/history. How do I stop a random website from overriding my settings in the future? If discord can do it through incompetence another website can surely do it maliciously and I really dont fancy this happening again. The "best" (and completely unrelated) I've found on how to undo this, let alone prevent it from happening again is pressing esc or f11 because of course everything these days has to drown in AI slop :/

when searching from the address bar (see picture) the first result (before firefox suggests) is not a bookmark and not history. what is it and how do i get rid of it? I want bookmarks to always be the first result. I just went through the library and it doesn't appear in history/bookmarks. thank you

Firefox keeps shutting down and it will open up when I tap on the icon. I have to reload it to make it work, It seems like I have to do this everytime I shut the pc.
