Hello I have an issue going on with the autofill info that I use. When I type my name, my 1st name comes out fine but when I type my last name it's now a misspelled last name. Seems like it all started with a new banking company that I'm with now. I 1st notice it there and I had to fill out forms to correct the info with them and it was kind of a hassle. I noticed that there was one extra letter added to my last name when I looking at my account info. Maybe when I was initially filling out my personal info with them, I might have spelled my last name incorrectly. I'm not sure. Sometimes I type words wrong. I'm not the greatest at typing. But since then I've noticed my auto fill info, my last name, has been bringing up that same incorrect last name. How can I fix that. I see solutions for editing addresses and passwords but nothing about names, personal info. Anybody know how I can fix this. It has become a nuisance. Thank you ahead of time.

I opened Firefox (V 145.0.2) on my Windows 11 laptop today and noticed that the starting window was the only one open, while I have had at least five windows open for quite some time. The "History|Recently closed windows" option is greyed out. I have closed and restarted Firefox dozens of times and my windows always came back until today. Is that window/tab history stored somewhere where I could recover it?

Thinking about backups of the browser state, I looked for my profile folder and discovered that it is empty - \Users\<username>\AppData\Roaming\mozilla is empty except for a file named vpn.moz. I then discovered that my profile seems instead to be stored under \Users\<username>\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles with the folder name e5di8bjy.default-release I now learned that this location is standard for installation via the Microsoft store - the so-called MSIX version. But it is wrong that the "About"profiles" page shows that my profile is in the AppData\Roaming, not the Packages, location. When I try to open that profile folder, I get a message telling me that it is not available on this computer. It seems like the profile info should be aware of the actual location?

Evil Corp (aka Microsoft) updated my Windows 11 PC from 24H2 to 25H2 and now I cannot access quite a few websites (i.e. Amazon, Bank!, etc.) and some take a long time to load (surprisingly, my Firefox Home page...Google...also takes a while to load) . I searched the internet and found many so called fixes and most are very complicated and many contradict others. A lot of them say to disable DNS and reset network stack (using the command prompt) which I do not know how to do even though I worked in the tech business for 40 yrs (mainly data networking)...I retired 20 yrs ago...so I'm old...so I'm not as savvy with computers as I used to be. I tried changing a few Firefox settings, but nothing worked, so I changed them back to the original settings that worked before the update. If someone could give me detailed (and hopefully simple) instructions to resolve this issue, I would greatly appreciate it. I'm am in a bind, so a timely response would be great. Thanks so much, Steve

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

I have two bank accounts. Both have been hacked and both banks traced it back to digital on line banking. they both claim that somehow hackers are getting to my personal info thru my computer. I do not use the phone of banking...and Firefox is and has been for a long time my default browser. Can hackers get my info from Firefox?

Not a question, but I am vying for your "Least Important Problem of the Day" award. Mozilla makes great products. And,

The recent new "window fades away" when closing Firefox (or upon saving a file) is weirdly annoying and unnecessary imho. Obviously not a deal breaker, but I'd prefer if the window just closed. I don't need to wistfully watch it fade away. Thanks for the chance to offer input. Why am I even writing this.

I sure hope my bookmarks don't disappear like folks I'm seeing here today.

For roughly three months I have been experiencing issues with Twitch.tv that I do not have on other browsers. Namely, after a random period of time the site will just "go out" on me. I can keep watching streams that are open, but any attempt to open a new window or tab results in a page with no elements loaded. During this "out" period none of my chats will send, and any other attempts to interact with Twitch will fail. After a random period of time, things will go back to normal.

I've tried clearing my cache and cookies, I've tried disabling and uninstalling all of my extensions, I've tried updating the browser, I've uninstalling and reinstalling Firefox, I've tried Incognito Mode, I've tried a DNS flush, I've refreshed Firefox and it didn't work.

I have found one thing that has worked though. I created two new profiles. The first had the issues occur again, but the second one hasn't experienced any of the same issues as far as I've seen, so I think the issue is with my settings. The trouble is, I don't know which setting is the issue, and deleting prefs.js doesn't appear to reset my settings, even after restarting my browser. Is there some step I'm missing regarding deleting prefs.js?

Please do NOT suggest using Firefox Refresh, as I am NOT interested in going through all the steps again, especially when it didn't work at all the first time I tried.

Hi there, My laptop undertook an update for Firefox and I have just discovered that all of my bookmarks have disappeared and I cannot find anyway to restore these. My laptop cannot access any profile, I have followed advice in other posts, but I cannot find access to this data. I have lost all my Masters Degree bookmarks and my BSc, which I need access to asap to continue. Can you please advise on how I can get these back?

I have checked my mobile Firefox and it still has access to these bookmarks but there is no way for me to export these files out of my mobile. I am worried about undertaking a sync (although it says it has) in case it deletes all of these bookmarks.

Your help is greatly appreciated.

I try hard to use firefox in headless mode for a python selenium project in freebsd. But firefox complains about GPUs and the absense of a X-Server, but this is a headless mode and crashes with a segmentation fault. Why does it want a GPU and X-Server in headless mode? Does not make sense.

The output when i try to start is : " firefox --headless

• • • You are running in headless mode.

Can anyone help me? Best regards Josef

I am trying to find the files for my passwords from an old profile after Firefox just updated and created a new profile. I have just created a Mozzilla account so my profile can start to automatically update with all of my old passwords, but I first need to manually transfer them from my old profile that didn't have a Mozzilla account yet. I have been following the steps for doing so from the "help" pages, but I haven't been able to find the files for my passwords.

Respected one, since 2 days ago, the sound was lost when playing video content on platform X. I did not make any changes in the settings for M.F. not even in PC, I HAVEN'T CHANGED ANYTHING FOR MONTHS. Do you have any ideas, advice... Thank You for taking the time to solve my problem.

Hello,

"The bookmarks and history system will not be functional" error message has suddenly appeared in just the past couple of days on my new DELL Inspiron 15 3535 with Windows 11. I have followed the first few items on the Mozilla Support page that comes up as soon as the initial Firefox opening page appears and that has not corrected the problem.

I have tried to follow the next few steps but can't really find what it calls for because I don't understand what it's talking about. I am not of the tech generation and do not speak the tech language. Most of the terms in there I do not know what or where they are on the laptop.

Is there anybody who could help me saw through the terminology and give me some ideas on how to simply solve my problem? All I really want to do is get to where my bookmarks are hidden and put them back in place where I can use them again.

Thank you in advance for any help anybody might have.

Kind Regards, Tom B.

I can't delete history. I know how to do it (ie menu, click "clear recent history" etc etc) but it just doesn't do it. I've uninstalled Firefox and taken the option to "refresh" instead of reinstall. Didn't work. Uninstalled it again. In the reinstallation I asked that it NOT import my settings etc but it did it anyway. Back came Firefox, complete with my history! I just can't get a fresh start. With regret, I'm starting to use a different browser. I dislike doing that but at present I have no choice. Whenever I use Firefox, I just clutter up the place and can't get rid of history.

I just moved to a new computer. Still using the latest version of Firefox (145.x). But of course I have a much higher rez screen. So I'm looking at many more bookmarks across the menu bar, and they are all very small. As are the tabs at the top of the window. I can not find a way to make these larger in Settings. Grok tells me to work with CSS in the profiles folder, but that doesn't seem to work. (And I bet that every time a new version came out, I'd have to move or remake that CSS file and/or folder.) Is this just the way it is on the high-rez screen, or can someone point me to a solution?

I cannot complete an online payment from a checking account on firefox. I get to the point where it says submit payment and it always kicks me back to the same screen. I have to change browsers to complete the payment. Is there a setting that is preventing me from completing the payment?

Had to recently reset my browser and lost all my history. Apparently it messed up my custom settings in some way as well.

New Tab still shows my FF homepage with shortcuts and history gone - I've managed to get those back but with one huge problem:

- Clicking on a shortcut opens it in the same tab, whereas earlier I had it working when clicking on a shortcut would open it IN A NEW TAB.

Where's the setting in about:config to fix this???

If this feature has been removed - why???
