Firefox Support Forum

whenever I try to use a theme that defaulted to dark mode in the previous update, it defaults to light mode instead. for some websites this means that it displays in bright white. i need dark mode. even when i set the toolbar colour (which previously controlled dark/light in Firefox Colour) to black it's on light mode. how do I get dark mode back, i hate this. this theme (picture attached) used to be dark mode but now it defaults to light. how do i get dark mode back.

I have this problem with both Firefox and Edge, private mode or not. After logging at addons.mozilla.org, it's requiring me to setup 2-factor. I go through the process and everything is successful. It asks me to enter one recovery code to make sure I'll be able to login. I enter one and it shows on the top with a green background that 2-factor was setup successfully. But then nothing happens. No redirection or links. I try accessing the site in another browser and I have to go through the whole setup again which also appears successful, but then nothing happens. I attached the image that shows it was successful. I have no idea what to do since there is no error and I have the same problem across multiple browsers. Any suggestions?

I have two identical computers running Firefox on Windows 7. No serious issues for 3 years or longer.

Just recently, version 100 showed "Unknown Source" instead of the normal UAC authorization window which lists mozilla.org as the source.

The 100.0.1 update showed the same warning.

This only occurred on one of the computers. The other one does not show the warning.

Firefox worked fine after doing the downloads anyway, but the "Unknown Source" is not right and makes the user think security is being compromised.

I've always used Firefox as my default web browser. Now that Microsoft Edge got loaded onto my PC I can't access a lot of my bookmarks through Firefox. I get an "access denied" response. I've tried removing MS Edge but it won't let me. Is there a fix for this problem? How do I remove MS Edge? Any assistance is greatly appreciated. Thank You. Dale P.

Morning,

I have always used Gmail on my firefox browser, for some reason for the last two weeks it keeps dropping saying it's not connected. i have my account synced over multiple devices and it happens on all of them I am forced to use Edge or chrome to have it work which of course i don't want to do

Now on Firefox 100.0.1 On earlier versions of Firefox I was able to set a particular url for my home(opening) page. That is still true. However, on past versions I was also able to make *my home page* appear on every tab I opened. On the current edition I get a choice of only Firefox Home Page (default) or Blank page. I cannot get my home page on the new tab. How can I bypass the restrictions of the settings under Home to get my home page on every tab?

That the question I need an answer to. Everything below this is explanation of why I want this and a complaint about how Firefox changes things that I would appreciate being passed on to the developers.

                                                                    <---------------------->

If I choose Firefox Home Page (default), I am *forced* to use the address box to put in my search terms. I have become accustomed to the various search engines with their splash screens - with the nice big search box in the middle of the screen (both horizontally and vertically). It is absolutely unnerving to me to try to type in the box in the middle and have nothing show up there but up above in the address box.

I am a project person in a multi-tasking world, which means whether I like it or not, I have to multitask too. For me to do this successfully, all my tools need to be where I expect and perform as I expect them. Even putting duckduckgo.com in the current home page/new window setting, doesn't get the duckduckgo splash page, but even though I'm not that technically advanced, I found a way of getting it in my home page window. However, the tabs section doesn't offer me an opportunity to put my own choice in.

I wish Firefox would stop tinkering with otherwise minor things. I understand fixing found vulnerabilities. I understand providing new services and technology when they're developed. But why force people to use search and tabs the way Firefox wants them to rather than the way the user is accustomed to.

Firefox has become so secure I can no longer use it for work. I spend so much of my time allowing links to be opened from clients, etc. Has anyone found a simple work around for all the freezes etc?

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

I have the following:

<html><head>
<meta http-equiv="content-type" content="text/html; charset=windows-1252">
<style type="text/css">

</style>

<body background="DNASidebar_files/DNA%2520Sidebar%2520for%2520Firefox.html">

<div class="folder">Databases</div>
<a href="www.ncbi.nlm.nih.gov/nuccore">Nucleotide</a>
...
</body></html>

To use this, I just click it in whatever folder it's in and it comes up in Firefox. If I run this on either Linux or Mac, when I click "Nucleotide" it takes me to the URL. If I do this on Windows 11, my URL looks like the following:

file:///C:/Users/xxxxx/Documents/www.ncbi.nlm.nih.gov/nuccore

What do I need to do on Windows to get the real URL to execute?

Thanks, Joe

Each time Firefox is refreshed, I must re-install extensions. How can I save the extensions so they do not need to be downloaded and re-installed ever time Firefox refreshes?

I'm using Firefox 100 on Win10 and can't save any bookmarks. They do NOT appear under the App Data Profile, which would not be acceptable even if they were. This change has made it impossible for me to continue using Firefox, unless I want to go back to Win7.

I simply need Bookmarks to work the way they did before!

Thank you for your time.

After i just updated Firefox to newest version .. I can not load any website anymore!!!!!! please make it so i can return to the previous version ASAP so everything works again.

Al those other solutions you guys give like clear cache disable en able etc don't work and take hrs of time

When oyu push a other update through some 1's throat atleast make it that it A)works B) option to roll back . TY

Recent issue, last few days. Unable to access Microsoft One Drive online without first having to Refresh Firefox each time. It is then accessible for a short period of time before the address link again breaks down into an incomplete address that does not open One Drive. I've repeated this process a number of times and each and every time the only means of access to One Drive is by Refreshing Firefox. Access to One Drive is fine on other browsers. I've cleared the cache, and run Firefox in Troubleshoot mode, but the only thing that works, and does so consistently, is to first Refresh Firefox. It will then go to the correct address for One Drive for a short period of time, before again breaking down into an incomplete forwarding address. I prefer using Firefox, but regular access to One Drive, without all these unnecessary steps, is a requirement

My Firefox keeps crashing. also I get this message often "Gah. Your Tab has just crashed". I uninstalled and reinstalled multiple times. I did a clean uninstall. I deleted all Firefox folders in Program manager and used account hidden files. Then reinstalled and it still crashed repeatedly.

Fire Fox no longer appears on the menu bar. I have to go to programs and open it each time I want to use Fire Fox. It will appear on the menu bar as long as I have it open but leaves the bar if I close it.
