I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

I'm using 128.0.3 (64-bit) for Windows, on Windows 10.

1. I open Firefox normal window. It has some pinned tabs. 2. I open an additional private window 3. I close the normal Firefox window. Only the private window remains 4. I close also the private window 5. I restart Firefox normal window. The pinned tabs have dissapered.

Thank you. Adrian

Hi, I'm not sure if this is a bug, or me not using FF properly.

I want Firefox in general to ask me, which profile to use when started. So in the Profile-Manager, I removed the checkbox for "Use selected profile without asking as startup".

Now, I wanted to create a shortcut for a specific profile, so I tried running `firefox -P "myProfile"` or even `firefox -p "/path/to/myProfile"`. In both cases I get the window asking me which profile to use.

Greetings, a couple of weeks ago I started getting a black page with the message that is the title of this question, "We can’t connect to the server at www.googleadservices.com." when I click results from a web search and even clicking on links from within pages I already have open. This has happened in the past but only once in a while and isolated incidents. However right now my browsers are almost useless because of it. It started with Firefox as it is usually my default browser so I switched to Chrome and then Edge and now they are all doing it. I have posted a query in Windows forums and Microsoft help because it is with all my browsers but I am also posting in the individual browsers' help sections as well to get as much info on this as possible because it's really frustrating me and I want it fixed. I'm only able to visit 1 out of maybe every 25 pages I try to click on from any of my browsers!

For the past couple of weeks I have been getting the "Hmmm, We're having trouble finding that site" error screen quite often from both searches and links from other sites. It's always happened once in a while but it hasn't been anything bothersome. However recently it has become quite bothersome because it's happening a lot! However not all the time. It's not completely broken, just mostly. And it's happening while trying to visit sites that I know and visit frequently such as Amazon, Ebay, and even sites for local businesses that I trust and know are working. I'm not having any internet issues with my home wifi, nor am I having this issue with other browsers. I have however also noticed it on my Firefox mobile browser as well. I posted about this a few days ago and got some email back about an issue with my post. If this happens with this one and I'm unable to get this resolved I will just get rid of Firefox on my devices. FF has been a long time favorite and is usually set as my default browser but if stuff like this is going to continue, I can change that real fast. There are plenty of other browsers that work just fine and have decent customer support.

I'm getting this Server Not Found page error very often with a message that says; "Hmm, We're having trouble finding that site" on a black screen with a doubleclick.net address in the address bar and some options to check my internet connection and firewalls, etc.

2ndly its hard to get in touch with your crap support line can you also make it easier to get hold of your team rather going through 1000x pages, why is everybody not keeping any proper contact information you and google are same [edited]. exceptionally down the drain support. [edited] sort it out. or else i have to take further action.

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

Supposed to be: test [sound=https%3A%2F%2Ffiles.catbox.moe%2Fe547nk.mp3].png Downloads as: test [sound=https_3A_2F_2Ffiles.catbox.moe_2Fe547nk.mp3].png

Hello,

For the past couple weeks, comments on WSJ articles and opinions have not shown up in Firefox. They show up just fine if I use Edge. I'm running Firefox 128.0.2 on a Windows 10 computer.

I run uBlock origin. I tried disabling it, but that has no effect on the problem.

Any help would be appreciated. Thanks in advance.

Some months back when I get gmail from the Economist and try to go to an article the gmail links to I get this: Our apologies. An error seems to have occurred. The article actually appears very briefly but then gets overwritten by this error message. I am using an up to date Windows 10 PC.

When I go to Microsoft Edge this behavior does not occur. In Firefox I have tried clearing the data and cache but to no avail.

Any thoughts on dealing with this? I do not want to go through many heroic steps to fix this.
