Diễn đàn hỗ trợ Firefox

I'm trying to diagnose an unusual problem on a relative's computer elsewhere in the country via TeamViewer. When Firefox is initiated, the same picture (a man taking a shower) appears, and the VERY 'long URL starts with a Yahoo image file (yimg) and also contains buzzfeed.com well into that URL. I thought I could easily diagnose this, and have failed. Home page is set to blank page. I cleared all browsing data. When that failed I exported bookmarks, created a new profile, and the problem still continued, even before importing the bookmarks or adding any extensions. Something is retaining the unwanted startup behavior. Tonight, out of desperation, I will reconnect and look through the registry.

Can anyone surmise why an unwanted URL is being invoked upon Firefox startup?

Recently I’ve had a few Firefox problems on my W11 desktop. Sometimes when I try to load a website, nothing appears until several seconds (30 or more) have passed. During that time, the bottom of the screen shows the message Transferring data. Then, after that long wait, very often only a top piece (1/3 to ½) of the page appears. If I wait long enough (a minute or two), the rest of the page appears. Another problem is illustrated in the two images. When I go to AARP, I get the first image. T then press the Reload button and the second image appears. This problem is fairly recent. Previously, the first image always loaded with not problem. Any ideas of what’s happening and, even more importantly, how it can be fixed? Thanks.

The problem that is occurring with Firefox is one website American Airlines, I can not log in to my account with Firefox, however Chrome has no problem logging in. Running Windows 11 up to date Firefox 147.03 64 bit. below is the error message I get Access Denied You don't have permission to access "http://www.aa.com/homePage.do" on this server.

Thanks for any help. Rick

When opening Firefox version 147 it asked if I wanted to install updates and after answering affirmative, then it gave "Error: Platform version '147.03' is not compatible with minversion >=147.02 maxversion <=147.02. Maybe try to reinstall Firefox?" The browser will not open. What is the workaround??

Please return my Computer to using Firefox default as my browser as it was 2/01 /2026.Ive tried several times to do this w/o success . I was using windows 11 and have been trying to get rid of MS365 which I never used but have been charged for a solution , but have been blocked and refused cancellation after they asked me to change my email address and PW . Insanely confusing !

After the last system update, I now am being asked to enter my "Primary password", every time I open a new page. When I try entering a password , it is not recognized and I have to click on cancel in order to proceed. I have used what I recall was my password but it is recognized, but I don't get a message telling me it is the wrong password. How can I get back to the previous version that did not ask for my Password. Is that an option?

My pc just did the latest update, the one with the new Logo. It wiped out all my bookmarks and passwords. I can reset the passwords, but I have hundreds of hours of research which was all bookmarked. I have changed laptops four times and each time I did, I would just sign into my Mozilla account and it was all downloaded into my new one.

Did anyone else experience this and were you successful in retrieving this data? Do you have any tips? This was important information on a health condition and I don't know if I can find all of this again.

Please, please help. I tried doing what I found in your forums but nothing helped. Could it be that the information was wiped out by your servers and it's permanently gone? I really need help. Thank you.

Hello, Having followed the advice as under: If you've previously made use of Firefox Sync, please make sure you're signed into your Mozilla account and have enabled Bookmarks within your Sync settings, because Firefox will automatically download any available data from our sync servers as long as you are logged into the account you used to sync.

Additionally, please consider that if your bookmarks are still available in the local storage of another device, signing into Sync on these devices will let you upload this account data and make your data accessible on any other devices you enable Sync on.

Andd checking the the Bookmarks tick-box was checked [as was last attempt] I tried to sign in to open the required page, but got 2 x 'error' windows, as attached, one for enail address [been using this for 2 yaers] and the other for password [how did I get this page up with the wrong password??]

I'm obviously a very dim Brit . . . . . please would you advise me as clearly as possible about whatv the heck is going wrong, thanx Kr CB

Before the new profiles update in Firefox I was using the old version of creating profiles and I want to move that profile into the new profile method. Is that possible?

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

I searched how to disable any random new AI features Firefox was about to cram into the browser.

I was served this support page that says I can "Block new and current AI features (single switch)"

Simply, the described feature to disable AI features isn't in the settings. I've look and tried searching for "Block AI enhancements" & "AI controls" but no luck.

Please tell me they haven't given the writing of support pages to some shitty LLM.

Hello, Until a couple of days ago we have been connecting regularly to the samaritanspurse.org website but now the connection times out. All other websites connect with no problem. What can we do to correct this situation. Thank you
