I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

I've seen on this forum from April that people are having an issue with Firefox and Google Passkey. I'm trying to log into my gmail accounts and can't get passkey to work. It freezes the browser and I'm not sure why this hasn't been resolved. Mac updated to Tahoe recently and I was on Sequoia 15.7.x (not sure exactly. Still froze. Photos are to show what's happening and that I needed to Force Quit each time.

Every time I update my drivers for Nvidia it of course reloads the screens. This causes all the tabs in Firefox to become separated on the Windows 11 taskbar. In other words, it looks like I have a new firefox window open for each tab (which I'm assuming is how it works but it's hidden most of the time).

It's not a HUGE deal per se, but it is kind of annoying. I have to close then reopen Firefox.

Like seeekerman who initiated the now-closed discussion at: https://support.mozilla.org/en-US/questions/1433369, I have used Firefox since its first release. With one exception - open image in new tab - I never use tabs. I want all the usable vertical space I can get.

For some time, Firefox on Windows (Windows 11, FF 143.0.4) has been showing a tab bar under the menu items, and above the bar with the URL etc.

How can I hide this when the FF window has only one tab, which is almost all the time for me?

The solution provided to seeekerman in that discussion, on 2023-12-08, was to create a userChrome.css file with some special incantations. I tried this it did not work.

Hello, I wanted to create a script that doesn't allow me to disable a certain extension. For that I thought to locate the file in which the states of extensions are put. I searched online, and the answer appears to be that such file is available in extensions folder in my profile. However, I am unable to find extensions folder under my profile.

I would appreciate the help.

Hi, can the function mention above be remove or flag off somehow? For me watching icon is already enough. cause when hover the side of the website to navigate accidentally expand the sidebar and in some time is just expand many times probably due to a bug.

My father used my computer and synced all of his firefox “stuff”, i need to get rid of all of it.

I tried to log in, but came across a message that told me it would just merge with his stuff. I would like his bookmarks and passwords gone so that only mine occupy the browser.

Is there a reset?

Hi, I have been trying all day to get my Trend Micro program working on my Firefox browser, including Password manager. These programs work ok on MS Edge browser, but I can't get it to work on my Firefox browser

Hi, I am having this problem where I am watching a video and there is a very annoying white line at the top of the screen, I have already tried the trick to turn off the titlebar but its still there. My version is updated all the way as well, what do I do now?

Does Firefox support webAuthn passkeys stored by the browser? I have an app that I am working on and I would like to be able to use this feature.

If Firefox cannot store passkeys can you explain why this has not been added?

Hi Folks, Recently I have been having an issue with accessing a particular website which is asus.com and the nature of the issue is as follows. Every time I attempt to login I receive the following error message.

The browser could not find the host server for the provided address.

   "Check the address for typing errors such as ww.example.com instead of www.example.com.
   If you are unable to load any pages, check your device’s data or Wi-Fi connection."

It should be noted that this is the only website that I am having this issue any and all assistance in resolving this extremely annoying issue will be greatly appreciated

I've noticed that I've got both the 32 bit (../Program Files (86)/..) and 64 bit versions (../Program Files/..) of Firefox installed on my pc. I didn't install both and both appear to be the current version. Is this normal behaviour? Only one instance appears in add/remove programs, but if I go to default apps, Firefox appears twice (presumably the 32 & 64 bit versions). If this is not normal, does anyone have a suggestion as to how to remove the 32 bit version without damaging the 64 bit one?

Firefox used to close completely when I close the last tab. The last update broke that behavior. How can I get it back the way it was? This new behavior is sick!!!

Hi everyone,

After enabling `privacy.resistFingerprinting = true` in `about:config`, I noticed that Firefox’s built-in PDF viewer (`pdf.js`) is always displayed in **light mode**, even though my system and browser themes are both dark.

I understand that RFP forces `prefers-color-scheme: light` to prevent fingerprinting, but this also affects internal components like the PDF reader. Unfortunately, the PDF viewer doesn’t provide a manual dark mode toggle.

Is there any **official or safe workaround** that allows keeping RFP enabled while still having the PDF viewer use dark colors?

Thanks!

So Im currently trying to watch young sheldon on netflix, and im doing it through firefox, and it wont work, it says error code f7701-1003, thank you for your time.

I used to be able to clear all data with no problem, but now it's holding to Gmail login data (I think that's the problem, anyway). I clear all data after each browsing session and have been doing so for a long time, but it's not working anymore. But it is working on my husband's laptop and we're on the same version of Windows (11) and have the same settings. Can someone please assist in figuring out what's happening behind the scenes? Thank you!
