Decided to switch to firefox from brave. Am completely unable to run Firefox. Doesn't even show up in task manager. I have one split second of a window, then it vanishes. Tried safe mode, tried running as admin, nothing. Brave and edge work, and I even downloaded opera to see if it would mess that up too, but opera booted fine. Running Windows 10 22H2, OS build 19045.3324. Any help is appreciated.

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

I bought this laptop because it had Windows 10 so I could download firefox, The laptop immediately updated to Windows 11, no way to stop it. I am locked out of my microsoft account, have been for years. How do I get firefox downloaded ?

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update

Now you've updated firefox, my tank of a Mac can't function with netflix. So thanks a lot you bunch of techy twats, with your great ideas to make everything better.

When we've got to the end,

we'll realise we cant get back to the beginning.....

Hi,

Because numerous things did not work with version 116, I downloaded previous version of the browser and installed it. When it started it said something like "you are trying to use the previous version so some things may not work, would you like to create a new profile?" and there was a choice "yes" or "exit". So I chose "yes" - because how creating a new profile could mean something bad? But it did - it deleted all my bookmarks and settings. I have used mozilla for years, everything was in it. How to restore the bookmarks and everything back? It, by the way, upgraded itself to 116 anyway.

Firstly, I have looked around on here for a bit and have not found anything.

I uninstalled Firefox because it was needing to update for a very long time, giving me a pop up every time I would open the browser, but if I clicked on the update button, it would just take me to a page on Mozzila that showed nothing regarding updates - if you scrolled down you'd get a normal download button for the entire browser which I already had. On settings, it would tell me my browser is up to date. Websites would give me pop ups saying I need to update my browser.

So I uninstalled it. And now I can't reinstall it.

I have Windows 10. On the Microsoft store, I have Firefox, but the "install" button does nothing. This is typical for the Microsoft store for me. On the Mozilla website, I can't get past the initial download page, I click download and it takes me to an error that says "this site cannot be reached" (so, please, do not link me to https://www.mozilla.org/en-US/firefox/all/#product-desktop-release or https://www.mozilla.org/en-US/firefox/new/ both take me to the same error page). I have already turned off Windows Defender, and turned off my ad block.

All of the info I have found assumes I already have the installation files, but I cannot access those because of getting the error I described above. No idea where to go from here.

Hi! I'm trying to access a graduate school admission interview due in the next few days. Unfortunately, I'm having trouble finding Firefox version 69. This is the version I have to use for Kira talents application - https://app.kiratalent.com/n/assessment/7sCGnz

I've reached out to Kira Talents already. But, I don't know if you have version 69 available and the systems requirement needed to download and operate a browser that old. It seems strange to me that a new application called Kira Talents require such an old browser. I mean, this is like 30 version earlier. What is the latest version? 90 0r 100 for Firefox?

Please any suggestion to help my inquiry would be much appreciated.

I'm anticipating to resolve my issue so I can start my video interview for my MBA application which seems to be blocked from me being successful at completing my application.

Thanks! Karolina

I have trouble downloading the newest version because it says that Firefox has ended support for Windows 8 and Vista.

But I DO NOT USE THESE OLD VERSIONS - I DO USE WINDOWS 10 on this computer.

Could you please let me know how to fix this in plain english so I can easily do it myself - I am no computer wizzard.

Your help would be greatly appreciated. Please write your answer to my email account: [removed email from public] ,

Thank you, Chris

I have two desktop icons for Firefox. Each opens to a different file. How do I clear the old file? What do I do about the message that Firefox can not update automatically? Where do I look to see Firefox file and see what date it is downloaded? If it is operational? Why is the same series of problems repeating daily?

FF would start to load but never completely finish so I forgot & stupidly did the troubleshooting mode or w/e that put me back to default so LOST all my settings, etc.. Strangely it's back "close" to normal except I was using Passbrow which the icon shows on toolbar but greyed out & I can't get it to turn back on. I have the "Old FF Data" folder but following the steps it doesn't show where profile is stored for me to be able to copy the old data TO. IF I can restore the old profile hopefully that would get it back working ALL as it was...but HOW??

I keep getting notifications asking me to update firefox every couple of days. I download the update, it goes smoothly, the notification disappears, but it comes back in a day or two. I also have my setting to supposedly do updates automatically, but that doesn't seem to be working. Please help!

Hi, I recently reinstalled windows, before that I wanted to make a backup of my data from firefox, addons, bookmarks, history and cookies. When I looked into google it redirected me to this page https://support.mozilla.org/pl/kb/firefox-backup-danych-przechodzenie-na-nowe-urzadzenie Great! I thought. I was logged in, synchronized and was ready to go. After installing new windows, I downloaded firefox, logged in, and nothing... no button to restore my addons or any data. So I searched far and wide and still didn't find anything. Please tell me how to restore my data it was synced.

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.
