Firefox Community Forum

as soon as i startup firefox it has a quick flash of white before the background image comes up. it happens on new profiles/troubleshooting mode.

i have tried disabling hardware acceleration and it doesnt seem to help.

I'm using FF 150.0 on a Windows 11 PC. I've signed into my Mozilla account but cannot find any mention of the Firefox VPN anywhere on the toolbar or menus except for the splash page that says "Try FF VPN". I'm in Colorado, US. Anyone have a clue?

How do I configure Firefox so that it uses the integrated VPN for certain websites but not for everything?

I can only see a way to configure a list of websites it will not use the VPN which is the exact opposite.

I'm not concerned about, for example, Amazon because there isn't any privacy there anyway. But I do not want my use of some other websites monitored.

Starting a couple of weeks ago I haven't been able to open PDFs in my Firefox browser. Although there are other pdf viewers, Firefox has features that I use that the others don't. I've tried all the various ideas I've found elsewhere online but none worked. I submitted a ticket to our IT helpdesk, but they say it's a Mozilla Firefox issue. The error message isn't helpful at all, considering there is no web server involved.

I get the error below:

Access to the file was denied

Firefox can’t connect to the server at local file What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

I can not sign into a banking site - last several months. It gives me this feed back : "Explanation The Application Gateway attempted to fetch the resource you requested from a junction Web server. However, the Application Gateway received an authentication challenge from the junction server while handling your request. There is currently no sign-on information configured for this junction server. Solutions Configure the junction with the appropriate sign-on information. Disable authentication at the junction Web server. " How do I do this? I try to keep FireFox up to date . On Mac Tahoe 26.3.1

When Firefox updated 149.0.2 to 150. Every time, I am watching video any site when I click the pop out button Firefox crashes and sends a report. I copied the text file from two of them(last one copied to share data). I do disk image backups and went back to before the update 149.0.2. Turned off auto update in setting and everything is ok now. Any suggestions?

Is it gMail or Mozilla that is slowing down the time for gMail to open a new Message? My internet connection is consistently between 200-300 mbps. Also, how to I change the email address on my account? Or should I just start a new account? Thank you.

When I restart Firefox, or my PC wakes from sleep, my Firefox windows are all in a different order.

Also a number of Firefox windows often just die or don't appear on restarting Firefox.

Is there a way to make sure that the Firefox windows appear in the same order and number as before?

At the moment I have to close Firefox windows and start them manually loading tabs from bookmarks. I would have thought that there must be a better way but I can't find it.

It seems as if Firefox should number the windows and keep a list of tabs open in each window, but this doesn't seem to be the case.

What am I missing? Is there a setting I need to change?

I'm running Windows 11 Pro

I cannot find the new built-in VPN or any icon to add to my toolbar. It was offered to me after update 150 but it only brought me to the support page on how to add it to toolbar. The icon is not at upper right corner of browser. And I found no way via Customize Toolbar to add the new VPN to toolbar.

To be honest. Firefox is starting to be a big pain to use. I'm starting to see more and more of this screen where it say's "Be careful. Something doesn't look right" Even when i go to the advance and say proceed. Nothing happens and i'm getting no where. I know many of the sites don't have anything to do with asking for credit card, Scam or even having popup's. I test the sites in other browsers and there work without any issues. But Firefox is starting to lock me out of many sites due to this. How can i make this stop. As i used Firefox for many years.

The sample that is in the screenshot is a Anime data base that i have also used for years. But today shows this. But was working fine yesteday. What is going on and how can i fix it. So i can start using the browser that i love on the sites i want to.

updated to Firefox 150, What's New screen shows new free VPN and "Turn on VPN" box; sign in to Mozilla account, instructions to turn on VPN, but top bars show on signs on VPN --apparently VPN is NOT available to my computer (Macbook Air Sequoia 15.7.4) ?

Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?
