Firefox Community Forum

When I do a search on firefox I keep getting the following error and have to go through the CAPTCHA BS.

Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot.

This just recently started happening. I'm getting very tired of having to pick out crosswalks, or motorcycles of buses.

This doesn't happen when using Chrome. May have to ditch firefox!

I have to reset Firefox/Mozilla as my default browser every time I leave the browser and return. Each time I set it as my default browser, but I have to do it again and again. This is a new occurrence, as I have never had to do this until the last few weeks.

I really need some quality advice and will sincerely appreciate it if someone can guide me, because my head is spinning.

My Firefox program was recently re-installed by Dell. But it seems to be an older version and among other things I can't find my bookmark toolbar. So I'm hoping that updating Firefox will solver this problem.

Everytime I open firefox, a small window opens that tells me "Update available Download the latest version of firefox, Download or Dismiss". Hitting download saves the update for ver 151.0.4 to my harddrive. I have several of these files because of all the times I've updated forgetting that its already been updated to 151.0.4!

Why do you keep asking me to upgrade when I already did?

To get here I went to "mozilla support" and I clicked the box requesting you send me an email when someone replies to this. This "someone" implies that this person is part of your "community" not a mozilla employee, which is what "mozilla support" implies. After taking my time to follow your vague directives, I dont expect to get any help from you but I am hopeful.

I tried adding images which took me away from this page and when I tried coming back to this page, everything I typed was gone so I had to start over. So I'm not going to click on "share data" for the fear the same thing will happen. Thanks for that

As I run my hand up the lid of my lap top, I OFTEN hit the "X" on the browser and the PAGE CLOSES! I am so frustrated because all my tabs close and I see no way to get them all back open. WHY NOT? I know how to use "HISTORY" and under thT i USED TO BE ABLE TO TAP "RECOVER ALL TABS" i DON'T KNOW WHAT BROWSER that was... And if you had that option, I don't know what happened to it.

Das VPN lässt sich in der neusten Version optisch zwar aktivieren, scheint aber nicht zu funktionieren. Die 50GB bleiben ständig erhalten und reduzieren sich nicht , trotz durch Test´s mit erhöhtem Datenvolumen. Auch erreichen mich bei aktivierten VPN wieder vermehrt SPAM und Ähnliches.

When I start an email using the FF browser I'll type the address correctly but the text on the screen is gibberish. See attached photo. When I move the cursor to the subject line, the gibberish turns to plain text.

I can't copy it so I took a photo and attached it. I deleted Firefox and then reinstalled it. This did not fix the problem.

How do I fix this problem?

Firefox is up to date, Windows 11.

I frequently watch BBC videos but approx one week ago, they stopped playing. I have your VPN which is usually off as it give me no advantage, (this appeared following the last update), but I've tried switching on and changing to UK location. No change.

Can you give me some suggestions please?

For a while firefox has been having issues where on youtube in particular when tabs are closed they will continue to play audio for a bit after they are closed. More recently I have closed tabs and the audio keeps on going indefinitely after the tab has been closed. This is on the latest firefox (151.0.4 64 bit) on windows 11.

This only seems to happen with youtube and in general youtube playback is buggy, slow, and lags the whole browser taking several seconds to switch tabs to or from a youtube tab or even close it.

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

When I click the firefox icon on my desktop, I cannot open firefox because it says Cannot transfer data from s.aolcdn.com

Hello,

Since this morning, I haven't been able to access Bsky on my laptop because of a supposed HSTS risk, which means I can't add an exception to visit it. I use Firefox on my Android and going to the mobile version of the website lets me in no problem, so I assume there's an issue with my laptop.

I'd usually wait a few days and let it solve itself but just in case it's something on my end, I'd like to solve it! I'm on 151.0.4 (64-bit), don't use a VPN or an anti-virus, I have a couple of privacy add-ons but they've been here forever and they've never caused a fuss. I can post a screenshot of the error code and the certificate it sends me if it's any help.

I'd appreciate any pointers! Thanks!

I am using Windows 11 (Version 23H2, fully updated) and a Logitech C920 USB webcam. Before testing in Firefox, the camera works perfectly in Chrome, including Google Meet, as well as in the Windows Camera app. When Firefox is opened but does not access the camera, everything works normally in the system. When I allow Firefox to access the camera on a website requesting permission, the webcam initially shows a working preview inside Firefox. But, after the preview, the camera stops working in Firefox and shows a message asking me to allow devices again, even though permission has already been granted. After I test the camera in Firefox and then close it, the webcam stops working system-wide. Chrome then reports that the camera is in use or unavailable, and the Windows Camera app also stops working until a reboot. In addition, when this issue occurs, the Windows Settings page Privacy & Security → Camera loads continuously without finishing anything, but the contents are visible and clickable while it keeps loading. I have to reboot the computer to restore normal camera functionality. I wanted to use Firefox as my only browser, but this situation stops me from doing so.
