Firefox Support Forum

Trying to open kossyderrickent.com I was suspicious of its safety. I was offered the option shown in the attachment. Is this legitimate? I am not familiar with the site and I think it may be unsafe. Pls advise.

Hey guys!

    I'm running Win 10pro, Microsoft Office Pro Plus 2021 and Firefox X64.  I set Firefox as the default browser, but for some reason that setting isn't "sticking."  If Edge is installed, I can't find it.  Believe me, I tried, because I wanted to uninstall it if possible.

I'm still getting used to the new Outlook (I won't tell you what version I WAS using...) but this is throwing me for a loop...

If I do not have Firefox open: When I open a link in Outlook, a new window is opened in Firefox. This window does not include any toolbars nor are any of my customizations applied (themes, extensions) As a matter of fact, opening the link in this new bare-bones window disables all my extensions and if I want my theme back, I have to remove it from my theme manager and reinstall it, because the option to enable/disable the theme isn't there.

If I DO have Firefox open: When I open a link in Outlook, I get "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." If I close Firefox, I'll get that same bare-bones window and all my extensions and themes are disabled.

Has anyone seen anything like this before and can you help?

Thanks a bunch....

Hey out there,

I've recently been strugggeling with Firefox (got latest version installed, System is running Windows 11) in terms of not being able to use the "Sign in with Apple".

On Chrome it still works, but after typing in my Apple-iD credentials, Firefox doesn't let me finish the sign in. It doesn't work if I want to sign into an Application nor a website using the apple sign-in option.

I know there are different ways to sign in but I tend to use this one thanks to it's simplicity and would therefore be happy if anybody knew the issue or even better, a solution to it.

Grateful for any replies :)

I have installed the Multi-Account Containers add-on. When I right-click on a link on a page, I am missing the Firefox Multi-Account Containers element shown in the Multi-Account Containers KB article (see attached screenshot KBContextMenu.png).

My context menu looks like the attached screenshot MyContextMenu.png.

1. Has the Multi-Account Containers add-on been updated, and the KB article needs to be revised?
2. Is there a setting that I need to do to show this context meny element?

Every time I use Firefox instead of saying United States at the bottom it's United Kingdom. How do I change this to show that I'm in the States rather than in the UK? I'm using the latest version for Windows 10 which is Version 111. There are sites that are blocked due to it erroneously showing that I'm in the UK not the US...

I've logged in on a brand new installation of macOS (Ventura), but it does not sync my logins, passwords, etc. The settings for the sync are also enabled and it works fine on Windows and Linux. Also tried rebooting, but no luck so far.

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

As of today, all of my Firefox extensions have stopped working and all of the search engines have been removed from the Default Search Engines menu.

I've tried everything I can find for either problem, but nothing has worked and they seem related?

Extensions:

• Reinstalling extensions did not work. They're still listed as enabled on my extensions settings page.
• I'm not in private browsing mode and my extensions are set to be usable in private mode anyways.
• Extension icons don't appear anywhere in the customizing menu for the toolbar, including the overflow menu.

Search:

• Deleting the search.json.mozlz4 file did not work; it didn't create a new file.
• "Restore Default Search Engines" button in search options is grayed out.

Both:

• Reinstalling Firefox did not work.

I have no idea what to do at this point.

Hello,

When I try to log in to tradestation.com, I get a 403 Forbidden message. I have gone to Settings - Clear all History, and checked all the History and Data boxes, and clicked OK. Also, I only use Private browsing, which is set to remove all history, caches, etc. whenever I close Firefox. I have been logging in to tradestation 4 or 5 days a week for months, until today. Please help fix this.

Thank you, Barry

Hi, I disabled several options in About:Config, and a feature previously disappeared. When I pressed the scroll button in the diamond, it opened a tag and moved to it automatically. Whatever you do with the current tag, I want it. Please help me. ( I mean, it no longer applies to bookmarks, I want it to apply to bookmarks )

Firefox 112 update will not download completely. It just keeps saying it is downloading but it does not complete. I can't access some websites now since I have been trying to download the update. Please help. Thanks.

When I open "Extensions" (about:addons) by clicking the Extensions icon, I want it to start on my own extensions, not Recommendations. How can I make "Extensions" open to the actual Extensions tab? Or can I remove the "Recommendations" tab entirely?

I already saw [to remove 'Recommendations' tab in about:addons]. But about:config

 extensions.htmlaboutaddons.recommendations.enabled = false

only removes recommendations from the Extensions tab. And adding

 extensions.getAddons.showPane = false

does not work, the Recommendations tab is still there.

I noticed this first when I had to force Google to go into dark mode even though firefox was already in dark mode.

I have searched through some issue reports and have seen a lot of people mentioning that their system theme is not being detected properly. This is not that issue. I can set the firefox "Website appearance" to dark or automatic at which point the UI of firefox itself does do into dark mode so no issues there. However if I go to a website that tries to query 'prefers-color-scheme' and set its theme accordingly it always returns 'light'. This is the case even if I set the 'layout.css.prefers-color-scheme.content-override' to 0 in about:config.

I used this website to test: https://septatrix.github.io/prefers-color-scheme-test/

The issue persists when opening a website in a private window.

Let me know if I need to provide additional information.

Hello. I un-installed Microsoft Edge and Office 365 and now Firefox has stopped working (on another computer not this one).

This is the same problem that someone reported in 2021, but that thread has been archived.

https://support.mozilla.org/bm/questions/1356550

The advice then was to re-install Firefox and to download Visual C++ \ Visual Studio files ( especially VCRuntime1401.dll).

My problem is that I don't have a browser on that computer, I am completely cut off from the internet and can't download anything.

Is it possible to download the necessary files on this computer and transfer them to the one that has the problem? Thanks.

Firefox said I can edit PDFs now when I updated the browser, but all I get are annotation options. Is that really it? Annotation only (you know, like writing the the margins of a book)? Or can we actually edit (like, changing the text in a book), and if so, where are the tools?

Same as this question, but the answer is outdated: https://support.mozilla.org/en-US/questions/839240

Is there a way to do this in the about:config page?

There is an answer about holding `Alt`, but that is a workaround.

Is there a way to fully edit a .pdf file in the new Firefox browser? I know how to annotate, but I don't see any way to copy and/or paste. This originally came up when I wanted to copy one sentence from of an entire document. Thank you.

For the past few months I've been starting to have some trouble with other sites that I go onto. For example, on Google if I try to search something that has 'a' in it, it ignores the rest of my query and searches up everything leading up to the A. Even just pressing A it's almost like it's acting as a mouse-click, but this problem only seems to be occurring on Firefox, nothing else.

What's going on?

A few days ago, I tried to log in to yahoo mail, and started getting this after I clicked okay: "Redirecting . . ." (print screen below). Now I get the same problem when I paste links into the search bar. I think this started with the new March 31st update. It isn't just one site or application, which seems to suggest that FF is the problem. https://prnt.sc/dIc_AerJtR7g The tab gets stuck there.I cannot view my mail on ff at all, but I can on my phone, probably because I wasn't forced to log out and back in. I cannot paste links. FF is basically unusable for me right now except for sites that I use frequently.

It works on librewolf and brave, and im running on fedora 37 (using the flatpak package) i have tried every fix including but not limited to: reinstalling, troubleshoot mode, making a new profile and clearing cache. also the openh264 plugin always says preparing to install or smth but never does, thought id mention it in case its important.
