Firefox Community Forum

Hello: Suddenly when I go to click on a hyperlink in the body of an email, nothing happens. (I might see the pinwheel for a few seconds, but that vanishes and nothing is opened).

I am using: Firefox 152.0.5 (64-bit) Windows 10 Roadrunner email through Spectrum

Is this a Firefox issue or an email issue? Thanks in advance for any help!

Getting around 20ms for DNS lookups so thats not the issue. Why do I see Error Code: NS_ERROR_OFFLINE maybe once every several days when this Firefox has never been in offline mode and never will be? Env is MacOS 26.5.2 with current Firefox installed.

Hi, My browser won't save the open tabs. I lost my tabs multiple times now, I don't even bother opening them back up now, but it's annoying. I have activated ( and disabled/enabled ) the setting to open previously open tabs on startup.

What can I do ? thanks

I am suddenly getting ads across websites in Spanish, and my Amazon account flipped to Spanish. I used several IP geolocation services which identified my IP address is assigned to Mozilla Corporation in Queretaro, Mexico, despite my Mozilla VPN being designated United States. How do I solve this problem?

Up until version 141, the difference between 32 bit and 64 bit Firefox installers wasn't noteworthy, though it has clearly been slowly increasing overtime. However, starting from version 141, the difference between them doubled from 5MB to 10MB, meaning a nearly 13.5% larger installer for the 64bit version than the 32bit one.

Why is that? What happened? Are there are feature differences that would warranty such a large gulf in their installer sizes? It's the AI isn't it? 32bit users were spared the bloat of the AI.

I also see that starting from 115.16 Firefox suggests users that aren't on Windows 7-8.1 or MacOS 10.12-10.14 should use other versions. Given both x86 and Windows' immense reputation surrounding backwards compatibility, is this really a concern? Is there REALLY something supported by Windows 7-8.1 that wouldn't function on 10?

When I went to log into my email it would not let me without confirming my profile information by hitting the "Submit" button. I tried to find a way around this but was not able to. The information had my name, an erroneous zip code of 99999, and my phone number. Since the info was minimal I went ahead and hit submit. It said a confirmation would be sent to my phone, but I did not receive anything. I then logged into my email, but as I was logging in it said, "logging out" and then logged me in. I opened a new tab to research if the ATT profile confirmation was legit or a scam. I was unable confirm either. However, when I opened the new tab I noticed the Tiger favicon between two ATT favicons on my recent history. I attempted to confirm whether this Tiger favicon was part of ATT or Yahoo but could not find out anything it. I am concerned someone may have hacked my email and phone. Can anyone confirm whether this Tiger favicon is legit or who it belongs to?? (photo attached)

I'm suddenly getting repeated/multiple Mozilla Firefox "Browser Alerts", "System Warnings," and "McAfee Critical Virus Alerts" that are wrong and dysfunctional. They pop up every few seconds. They contain "Remove virus now" and "quick scan" buttons, but these only take me to a bright red screen that says:

"Deceptive site ahead Firefox blocked this page because it may trick you into doing something dangerous like installing software or revealing personal information like passwords or credit cards."

These come even though I haven't tried to access any "deceptive sites." I have to x all of them out to clear my screen.

There's obviously a defect in your warning system. How do I stop this?

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!

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

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

Firefox can’t connect to the server at 6938e629511d9131a58e28150289aa0a.safeframe.googlesyndication.com.

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.
