Hello, on one of my computers I have my new tab set to have 10 rows of pinned links. I went to `about:config` and copied the `browser.newtabpage.pinned` string. I then pasted it into the string on a new device I'm setting up, but it doesn't do anything.

Is there any way to get this working? My new tab on the device I'm setting up has none of the pinned links, just sites I commonly visit

Thanks, let me know if I need to provide any more information.

I have a requirement where instead of showing the 404 error or 503 error on screen, I want to display a blank screen. I have already tried to set the following configs to false -

security.insecure_connection_text.enabled security.insecure_connection_icon.enabled security.insecure_connection_text.pbmode.enabled browser.ssl_override_behavior security.ssl.errorReporting.automatic security.enterprise_roots.enabled security.tls.version.min

Is there anymore steps to do or any userChrome.css script is required.

PS : I cannot use any extension or addon to do that

How do we contact customer service with trouble shooting issues? It is unacceptable not to have a number to call or at least a chat function to talk to a live specialist

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 there,

I have a question please :

I can check the candidate type ( webtrc ) in Edge with this simple command : edge://webtrc-logs

Can you please let me know how I can check it in Firefox. I`ve searched the web but I couldnt find the answer.

Thank you in advance.

A few versions ago, Firefox (Mac) changed behavior when clicking on a link in an outside program. Specifically, if Firefox is not running and I click a link in Outlook, Firefox opens the clicked link in a tab but also opens my homepage in a second tab. Since I'm only interested in the clicked link at this time I don't want it to open my home page, just the clicked link. This problem is exacerbated by my.yahoo.com which causes a switch from the tab containing the clicked link to the homepage tab.

How do I get Firefox to only open the link that I clicked and not my homepage in addition? This was the normal behavior until a few months ago.

Mac OS 11.7.4 Firefox 110.0.1

Thank you!

I was previously able to connect to my local NAS using the server name, but now cannot. I verified that the server certificate error exception is still listed.

Here is the text of the error message I receive:

"Hmm. We’re having trouble finding that site. We can’t connect to the server at [server name redacted]. Did you mean to go to www.[server name redacted].com? If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)"

I am able to connect using the IP address.

Click on the Preferred Location dropdown with Firefox for Windows. You get the following.

Now do the same thing with Edge/Chrome on Windows or Firefox for Mac. You get this.

The font being used is Adobe ProximaNova-Reglar. Why is this happening and what can I do to fix it.
