I am getting a lot of pop-up messages for existing of many viruses on my computer. Please help me protect and then permanently remove these viruses from my computer.

I cannot connect with my on-line banking site. When I try, I get the message "Bad Request--Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. I am able to access the site using another browser, so there cannot be a problem with the site itself. This situation has only existed since Firefox did an update. So, the problem must lie with Firefox. If it is not fixed, then I fear that I will have to discontinue using Firefox as my online browser. Please have someone from technical support contact me. [edited email from community support forum]

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !

I can't delete the malware "Startfenster. I tried to find help with "Google"-Search. Without any success! This malware exists for me in "Firefox" only. Other browsers are not affected. Perhaps anyone can help me... Thank's!

Not sure if this is the correct topic, but I have been using Firefox for over 20 years, and after the last update, there is an icon missing from my Firefox browser page. It's the "file" icon in the very upper left corner of the window that allows "new tab", "new window", etc. I'm still using windows10, on an ASUS PC, but never had the problem until just recently. I've restarted the computer, reloaded the window, nothing works to restore that icon/function. Thanks - Mike B

I tried to use both robertipp@gmail.com and robertippolito6@gmail.com for my system (along with others until I retired).

I've tried to work with Mozilla, but I cannot get an early system and another laptop (two I've been working). I've tried to work with Mozilla process, but I just cannot to get it to work. I tried to work your process, but I seem your process as asking me to read data that I seem coming close, but working with us. The last information was data, but a little error (?, mine or yours) popped up. My data that I wrote up, then I changed my data for robertippolito6@gmail.com very carefully, but the error this time had to be your error or an blend of data because many of your team and mine are just mine.

I give up. I cancel my contract. I've had to take my laptop for many trips to help with my older brother and who suddenly died. I was spanning around for quite some time to work.

January 31, 2026 is effective canceled. Please refund to me as said.

I went through my laptop and turned off enhanced tracking protection for a variety of financial, work, etc. websites.

I was disappointed that this did not sync with my other computers.

Here's hoping Firefox developers will incorporate ETP exceptions into account sync.

After the new version was installed automatically, I cannot sign in my account with ChatGPT. Any solution? Even though the LOGIN button shows, it doesn't do anything when I press it. Thanks

As usual on forums, none of the subject choices exactly fit my situation/problem, so I apologize for any unintended misdirection.

How do I uninstall Privacy Badger. It's been disabled, but not uninstalled. Please be specific as to keystrokes, screens, boxes, location of item. Many instructions tend to overuse computer jargon or common industry synonyms used daily within their sphere, which a laymen cannot easily translate, and often raise more questions than they answer. Installed on my Firefox browser. Thank you in advance.

I use an iMac (2019) and MacBook (2015) but my tabs aren't syncing between the two.

I've refreshed the syncing a few times but the MacBook is still showing two lots of tabs for the iMac, and both of them are showing pages that are no longer open.

I'd really like to be able to move between the two so if anyone has any suggestions on how to get FireFox to sync, I'd be really grateful. :-)
