Firefox Community Forum

I continue to have issues with web site appearance. Whether I select "automatic" or off for "contrast control" previously visited links are turned purple. If I try "custom"’ for ‘Firefox’ nothing else seems to stay like I need it to be. I do not have this issue when I use Chrome.

Firefox browser when on Foxnews will crash and causes PC to completely reboot? This has been happening on multiple PC's in my house and has been happening for months.

I finally got the search field and the address field on the same line. However, the search field is on the left and I would like it on the right. When I "customize toolbar" and manually switch the fields, it does not seem to reverse them subsequently (after I enter "Done").

What am I missing here?

Thanks as always to you good folks who will share your suggestions with this low-tech guy.

when using two screens at the same time on windows 11, when switching to fullscreen mode, I get a part of the main screen from the right. I tried disabling extensions, it doesn't help. The latest versions of windows 11, drivers, and also the latest version of firefox are installed.

I get screen tearing on videos or when i scroll on any website. Only happens on Firefox, I've tested Chrome, Edge, Opera.

Smooth Scrolling is Off. Hardware Acceleration is Off. I've tried toggling "gfx.font_rendering.directwrite.force-enabled" Firefox is up to date.

None of this has helped.

I have 5 windows open in Firefox, yet only 1 of them is visible/accessible on the Windows Taskbar.

I know there are 5 windows open as Troubleshooting Information reports "Multiprocess Windows: 5/5"

Sometimes when I launch Firefox, the other 4 windows will be visible, and this current one will disappear. If I go to Recently Closed Windows and open that window, it will appear, but the other 4 will be hidden again.

Other times, I will launch Firefox and one window will be invisible, and it won't appear unless I close all the other windows, then it will suddenly appear out of nowhere.

Hi, I have a pinned a website that will not show its icon (it won't when unpinned either).

Using the latest FF, Edge will show an icon. Is there a way to refresh FF and make it refetch the correct icon?

Thanks

Photo of the icon I do get.

My desktop Dell windows11 lost History and bookmarks a few days ago and I asked for help yesterday afternoon and was successful in restoring them. when I turned on my PC this morning the History and bookmarks along with forefox browser were gone again.

I just got a new computer and when downloading and signing in to firefox on my new computer it somehow brought over saved tabs from my dad's computer and not my old computer. It did not used to be like this on my old computer however I created a firefox account on my old computer hoping that if I did that and signed in on my new computer it would bring over my saved tabs and info. It did bring over my info but kept my dad's tabs as well. Is there a way to get rid of my dad's tabs on my new computer without deleting them from his computer as well? I also then created a new firefox profile in hopes that when I signed in to that one it would only bring my information but it just replicated the original profile, now I am hoping to delete that second profile but I am worried that will delete all of my information because when I go to delete it it says it will delete a bunch of my saved information. Is that information saved in my original profile so that if I delete the second profile I created it won't delete the data from the original profile (which is just the same information on both) as well? I can't seem to find anything to sign out of other than the new firefox account I just created, I was hoping to sign out of whatever I originally signed in with and try a different sign in but I can't even seem to find anywhere to sign out. I am not sure how I managed to do this, but any suggestions on how to fix it would be greatly appreciated. Thank you.

Greetings Ya'll,

I have to apologize if this is a double post, but I came back to the forum, & wanted to see if there were any responses, but i could only find my post listed under "My Profile"/"My Questions".

My original post was made Dec. 19-2025

=======================================

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all. Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?

Stupid mistakes were made - I reinstallted windows and when I opened firefox I realized, that I did not know my password and also was not sure about the mailadress. I finally found an account with my mailadress but reset the password - it said that all data in the account will be deleted if I do that.

I got the old files recovered, but everytime I copy paste the old key4, login and cert file... nothing changes withing the browser. If I copy the whole old profile folder and exchange it with the new one and then I open firefox it just says "profile could not be found" and then firefox closes.

Is there any chance of recovering my old saved passwords or did I screw up entirely ?

Hello,

I have been using Firefox for many years and also have Bitdefender Security Premium running on my devices. Unfortunately, I am getting more and more messages like the following:

Function: Online threat protection

firefox.exe attempted to connect to ads.mozilla.org using an untrusted certificate. We blocked the connection because untrusted certificates are issued by unrecognised certification authorities.

However, I can confirm that Firefox and the add-ons are all up to date. But I also trust Bitdefender, as this message will not have come out of nowhere. What can I do to get everything working properly again? Thank you. Kind regards, NaIch
