Firefox Support Forum

When I open Firefox to my home page I get a bunch of tabs in the address bar which more or less duplicate my bookmarks. I don't want to see these anymore. I tried to go to: Settings / Privacy + Security / Address Bar / Uncheck Bookmarks. But I can't find any button to Accept Changes. If I simply close the this page, next time I open Firefox the tabs are back. Please help.

Hello everyone,

this here is a really odd problem and not one of the usual "firefox slow, internet bad" → "read the faq" problems as far as I can tell.

The problem: When using Firefox (110.0 64-bit Windows 10) I noticed already a while ago that downloads are slow, apparently frozen from time to time, websites took longer to load and looking at speed tests, I got really bad results. Furthermore, Firefox seems to slow down my internet speeds of the whole system, as I can observe in other applications which want to download or upload data. As long as Firefox is running (even if I am just in the default tab and doing nothing in Firefox) it slows the internet speed of the whole system down.

So I tried a plethora of things to fix this and I can rule out the following possible causes with high confidence:

• History, Cache, Add-Ons and so on: performed a clean re-install of Firefox, cleared all cache and history data, removed add-ons, reset to default, etc..
• ISP problem: performed repeated speedtests from other devices within the network, everything is fine within my local and wide area network, ISP does not report any problems
• Firewall & AV: turning on / off, even uninstalling, no effect observed
• Driver problem: driver updated, driver removed, used default Windows Driver, used Troubleshooter etc., nothing helped.
• OS issue: Nope. I even performed a clean new installation of Windows today, the problem remains. Furthermore: I ran the speedtests using Microsoft Edge and there are no issues (as long as Firefox is not running.)
• HW / System issue: Nopes again. I have used a live Ubuntu-image to cross-check whether the HW might be an issue, but running speedtests using Ubuntu and Firefox worked well.

I did not observe similar effects on other machines using Firefox under Windows in my network. So it seems to be a very specific problem within Firefox under Windows 10 on my machine.

By the way the machine: HP Pavilion Gaming - 15-dk0200ng CPU: Intel Core i5-9300H RAM: 16 GB DDR4-2666 SDRAM WiFi: Realtek RTL8822BE 802.11ac (via PCIe) (I also have an Ethernet chipset on this system, but since I have tested everything using only WiFi I'll omit the info here.)

So is this a bug of Firefox? Or am I missing something?

Attached are some screenshots of the disappointing test results using Firefox. (I have similar problems on other sites like speedtest.net or the speedtest of Google). As reference: I've got 500 Mbit/s downstream and 50 Mbit/s upstream. Usually these speeds are achieved from other devices (or other browsers on my system), or are at least within the top 80%. But what I get with Firefox is significantly worse. It's also strange that the speed goes up first, which is fine, but then falls down completely after reaching some point. A few seconds after that it goes up again, but much much slower.

Thanks in advance for any help!

Hi, I want to sign in to icloud with my appleId via https://www.icloud.com/ with my security keys YubiKey 5C NFC, but the page states that this browser does not support security keys. Every other service as Gmail or Facebook etc ... works perfectly and the security key pop-up will show up but not for icloud. I have hardened my Firefox with uBlocker and disallowed cookies. Can it be because of this? I attached screenshot. I am running Win10 with firefox 110.0 (64-bit). I have contacted apple support and they told me it is Firefox issue. Thanks for reply.

Why am I locked out. I play every day and today I can't get through and Google said it might be a Cookies issue. Need help please. Not very savy re. Cookies. I am a Senior.

When going thru my bookmarks why does it jump to top of list when I go back to list. Very inconvenient when searching thru my bookmarks. Started with last update 110.

Recently, my Firefox browser started stumbling when using Google Sheets. The top of my screen shows "Trying to Connect" or "Reconnecting" wether Im on wifi or hardlined. Chrome does not do this.

Somewhat recently I have been unable to use my scroll wheel to scroll pages up and down.

I can scroll up and down in every application on my computer except Firefox.

Things I've already tried: I've tried turning hardware accel. on and off I've tried turning off auto scroll and scroll lock. I've tried using other mice. I've tried using a different Firefox profile. I've tried restarting my computer.

I have been AVOIDING doing any changes that erase my cache or restart Firefox in anyway since I REALLY don't want to lose any of my password and history data. If it's the only way, then I'll deal with it when I deal with it.

What makes this problem weirder is that I can middle-mouse click and scroll the page up and down with that, but I cannot scroll the page manually with the wheel at all.

What could possibly be the issue? Someone please help! It's not like it's making me terribly angry, but it's very, very inconvenient and no normal fixes seem to be fixing this super simple issue.

When I try to clear my browser history for the last hour all of my logins are reset (even tho i login on those websites more than an hour ago) and I have to sign into every website I visit again. It worked fine before version 110

the latest firefox update has disabled scrolling/ i have tried changing the settings in firefox and no changes make any difference. scrolling works on other apps perfectly fine.

This issue occurred in firefox browser (110v), i can't open picture into another tab without a warning, reddit video player won't play, my home menu not appeared properly, bookmark also.

"Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for i.redd.it. The certificate is only valid for the following names: default.ssl.fastly.net, fastly.com, *.a.ssl.fastly.net, *.hosts.fastly.net, *.global.ssl.fastly.net, *.fastly.com, a.ssl.fastly.net, purge.fastly.net, mirrors.fastly.net, control.fastly.net, tools.fastly.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN"

Whenever I try to fullscreen a Youtube video, it just displays a black screen. It is not temporary, and the picture never loads in. I have tried the full-screen-api solution. Didn't work. I tried deleting my cache and cookies. Didn't work. I tried disabling hardware acceleration. Didn't work. I restarted my machine twice, and that didn't work And I am on the most recent version of Firefox.

I am not fluent in English, there may be errors in translation.

When changing from theater mode to full screen, a black screen is displayed and the screen does not appear.

After the recent update the scrolling function withe the help of mouse wheel is not working. what kind of an update is this? please fix this issue as soon as possible. thanks

I have not turn off the PC yet and just clear all the data last 2hours.

I tried this and it shows history only 1. Press Windows + R, type cmd and click OK. Or you can also type cmd in the Windows search bar. 2. Open Command Prompt, type ipconfig /displaydns, and press Enter. Now, you can see the recently visited websites. You can view, copy & paste the important websites into Firefox, and save them as bookmarks.

Why? because when login with rnc@#!3@!@gmail.com it ask for phone prompt again basically do not ask this device all gone!

I keep advice said when clearing cookies and cache all data will gone he say ok and proceed to regret please help.

Hello!

I have downloaded Firefox but I cannot chose a location for my downloads when using the browser - so all of my downloads are failing. I am using a Macbook and currently have no location for my downloads. Even when I click the "Choose" button under Preferences, nothing pops up and I have no options to select. I also cannot type into the "Save files to" section.

Any help is welcome, thank you!

I've recently updated to version 110.0, and I immediately noticed an issue with my bookmarks where my scroll position in the bookmarks list isn't being saved after opening a tab or two. It keeps resetting back to the top of the list after a few seconds.

I don't know if this is a bug resulting from the latest update or what, but I know I didn't have this issue with bookmarks prior to updating to 110.0.
