Firefox Support Forum

i have just downloaded Firefox and i go to open in and it flashes open an close immediately. the occurs every time that i open the program. i have reinstalled it multiple times to see if that's the issue, used the Microsoft store to download it, the website, i tried to get the beta that didn't help and i was just wondering what the issues was and wondering if you could. i looked in the error message folder as well and its empty.

So, I've had this problem since last 3 months. I'm using Firefox with auto-update turned on. Right now my version is 110.0.

Every now and then Firefox stops to load any websites and after closing it and opening it again it won't open correctly saying that my profile was created using newer version of Firefox and I need to create new one. At some point I was on default-release-9 until I asked about it on Reddit and got a reply guiding me to check compatibility.ini in my profile directory and fair enough, when this happens, compatibility.ini indicates Firefox version 119 so Firefox is right thinking that values don't match.

But the definitive question is how do I stop Firefox from messing around with that file? I'm honestly tired of manually editing it every time Firefox stops working. I know that website loading problems can stem from my excessive uptimes but this is an issue I can work around by restarting Firefox from time to time.

Hi New Dell Inspiron 15-3000, installed Firefox 100 in new laptop, transfered all files via LAN from old laptop All websites work ok except 2 of the 4 banking websites I use. One site will not accept my login the other will open after putting in my login twice Have gone to "troubleshoot mode" and both sites work , go back to "normal" and they do not work Any clues how to fix this, not to technical please I am not a computer whizz and all children have left home Many thanks Ron Managh

When I log in to survey websites (e-rewards or one opinion), they get the neverending clock so I can't choose & take a survey. I get into the website & can do everything except for taking the survey. Works fine in Edge.

When signing in to my Barclays On Line account,the 2nd page of the sequence is distorted such that one vital box can only be seen my reducing the page to 65%. This happens on two PC's both are using Firefox. Browsing with Edge gives no problem! One PC is running win 10 the other Win11 - both have Norton 360 AV. Is this a FF or Barclays problem?

Hi,

Since the yesterday installment of Firefox, the Download list popup every time I download a file. I tried to toggle about:config->browser.download.panel.shown->false but every time I download a file in toggle back to true & the list pop up

It's very annoying. Any suggestion please?

I was wondering if I can enable this function (that green text saying "Mozilla Foundation (US)") or it was deleted. If it's still in browser, can someone show me how to enable it?

Hello,

I am learning to look at websites with help of the development tools and the inspector tab and I am trying to get into how the web works and how the different programming languages interact and so forth. When moving the mouse over parts of the website, the relating code is highlighted in the inspector tab. I am having an issue as follows:

The first image shows a part of the website code. The mouse cursor is on no specific position, I marked its position with a blue arrow.

In the second image the mouse is over the red "free options" button and in the inspector tab a div appears out of nowhere. It does not appear in the code unless the mouse is moved over the button and disappears as soon as the mouse leaves the button. I have never seen that before (maybe because I am a beginner) and have no clue what happens there.

Is that done with javascript? Or with php? Or with css? Or anything else? What happens there and how can the actual code change?

In the inventor tab, does the code have to do with the DOM rather then the sourcecode of the website is that right?

Please give me some light =)

This is a very bizarre problem. Basically I can't install any Firefox addon neither on my desktop OR may laptop. I noticed this issue just couple of days ago. When I try to install any addon normally, from a link, it tells me that the addon can't be installed because the file is corrupt. Tried several addons, all same problem. On my desktop AND on my laptop. On my desktop I'm running ver. 103, but on my laptop I still had ver. 102.1, so there is no Firefox update issue. When I try to install addon from xpi file, it tells me that I have no permission to open that file and that's it. I tried to take ownership of that file but it didn't solve the issue I tried to disable my AV program, but it didn't do anything. On my laptop, I tried to refresh FF, no help. I tried to start FF in safe mode, same problem. I created new profile, same issue. Eventually, I totally uninstalled FF, removing program itself, removing Appdata folder and even registry entry. Installed fresh copy of FF, same problem exists. Then, I noticed one thing. When I tried to sync fresh FF installation on my laptop, it synced everything, EXCEPT for addons. So, something is preventing me doing anything regarding addons. Themes install just fine. I've struggling with this problem since yesterday and at this point I totally ran out of any fresh ideas how to solve this issue, thus posting here. I'll appreciate any fresh idea as what to do next. Thanks

Dear Firefox,

Since yesterday, every time I tried to access my Google email and Google drive page, an error message pops out as shown in the image attached. Please help, as I would like to continue to use Firefox, however, this issue is affecting my work.

Thank you in advance

I got a new Acer laptop with windows 11 (64bit). I downloaded FF but when I open it, it just gives a blank page. If I type in an address nothing happens. I have tried reinstalling but nothing seems to work

Every time i open Firefox a little window comes up and says for a fraction of a second that im using an older version of Firefox (Even though that i'm using the latest) and then it crashes. I've tried everything, from reinstalling, rebooting, making exceptions in the firewall and even manually installing Firefox, but nothing. Before anyone asks, i do not have AVG, Avast or Commodo, and the Firewall is the basic Windows one. The issue is very similar to this one:https://support.mozilla.org/en-US/questions/970099. I also tried what they said, but unfortunately nothing woks for me.

Hi folks, I tried to open my Firefox browser today and nothing happens when I dbl click on the icon. I tried uninstalling / reinstalling, no change. On the uninstall window it gives you the option to use the Firefox refresh / repair facility which I clicked but there is no response from the programme. I read through the trouble shooting tips and tried to bring up the profile manager using the windows - run box (firefox.exe - p) but nothing happens. I have disabled windows defender firewall and I use Webroot Anywhere secure which I also disabled but still wouldn't run.

Could anyone suggest anything else I might try - thank you.

I seem to remember that there was a setting to open with a standard set of sites, selected by me. I may be mistaken but it is a pain to keep opening these everytime I log on. Any help would be appreciated. Thanks in advance.

To whom this may concern, I am requiring about getting back bookmarks I recently just lost. I had a list close to 3000 of them, however I reformatted my PC and found out there weren't being synced recently and don't have the bookmark backups in my file list anywhere. Have tried many data recovery software to no avail, if there's a possibility I could have access to my last few bookmark updates to the cloud that would save many headaches Thanking you

Greetings!

This is so strange.

My Screenshot Icon in FF 120 is gone. Tried adding it back, but it's not there under More Tools -> Customize Toolbar. Overllayed Firefox with a new install - no change. Disabled/enabled extensions and themes. No go.

Am I the only one? Any ideas?

Thanks. :)
