I have 2 Firefox account have to use both without mixing information's in one browser?

my mother is teacher and I'm student and we have our own accounts but I didn't find a way to use our accounts in one browser without mixing our information's like how we can do it in Chrome and log in with several accounts and emails. so there is a way to do it?

Up until today, PDF files would open automatically in Adobe where I could look at the file and print it. Today, Firefox will only allow the file to be downloaded. This causes me grief, an extra step. One of the main reasons I use Firefox is for this feature. Is there a way to change settings so that PDF files will always open in Adobe?

When I use firefox on my main display (1920x1080 144h 16:9) in full screen there is a noticeable white line in the bottom, not using full screen fixes it, but a pain in the ass to resize it all the time. I tried using the browser on my secondary smaller display (1920x1080 60h 16:9) and there is no white line. This seems to be a bug, how do i fix it?

I'm running Win10. When in FF browser the taskbar, which I have set to appear at the bottom of my screen, does not appear. I normally use "auto hide taskbar" setting in windows, and tried to turn this off to see if the taskbar would again appear while using FF. It did not. So, the taskbar seems lost when in FF. This has happened before, appears it is an intermittent issue. My windows10 is fully up to date as is my FF browser.

Hi there, I am working on a site with Segment API and need to load their JS on my site for it to work. Whats happening is, I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.segment.io/v1/p. (Reason: CORS request did not succeed). Status code: (null)."

The weird part is, it happens only in Firefox incognito mode. It works on Chrome, Edge, Opera.

I am wondering if this is by design or if it is a bug.

Firefox version 98.0 (64-bit).

Hi!

I can't scroll with the mouse wheel in Firefox. It works fine in other browsers and programs.

If I switch to Safe Mode, the scrolling wheel works. But if I switch back to normal mode, the wheel does not work again.

I tried to switch off and switch on "Use autoscrolling" and "Use smooth scrolling" settings, but it didn't help.

Unfortunately, "Refresh Firefox…" and reinstalling browser completely did not help.

I am at a loss, please help.

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

Hi, I'd like to get rid of the status bar at the bottom left corner. I know it goes away and it seems impossible to remove. But is there any way to remove it? I add an image to show what I want to remove. Thanks in advance!

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

How to import passwords from a CVS file (such as create by Keeper password manager) into Firefox Version 101?

I looked at older questions (example: <<https://support.mozilla.org/en-US/questions/1329981 >>) but the solutions do not apply to the latest Firefox version.

Thank you in advance for your help

If I open Google Maps in Firefox, it shows I'm in Lubbock, Texas. I am not. I'm in Arizona. Google Maps on Chrome gets it right. Bing maps gets it wrong in Firefox but right in Chrome too. Same with Google Earth in the browser. My IP location is correct and shows I'm in AZ. It's seems to be a Firefox issue. I've turned location off and back on. Cleared cookies. I'm at a loss.

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..

A recent Firefox update has totally disrupted our ability to print from browser windows. There used to be a "Print Preview" button that allowed us to set things up the way we wanted them. That's now missing. As a result, stuff that used to cost us for ten pages now costs us for twenty pages. Also, when we print double-sided, the second side prints upside down.

This strikes me and my wife as a horrible development, and we would like to go back to the old version ASAP!

Recently if I browse pages with maths forumulas they do not display coorectly, instead the underlying Tex or LateX code is shown.

I have several computers and I use Firefox on all of them, but curiously this problem does not happen on all of them, some show formulae correctly.

The image attached shows an example at Wikipedia - Lagrange point . The upper portion is Chrome and displays correctly, the lower portion is Firefox where the formyuals do not display correctly.

This is only started recently. Previously I had no issues with formulas displaying on any pf my computers, for many years.

I just updated to 95.0. I use default Firefox home page with the Search bar. The background turned to black with this update. The background has also turned to black for some of my bookmarks or sites I go to. Settings, Language and Appearance, Colors, Text is Black and Background is White. I have never changed that. How do I get the background back to White?

Hi,

I'm using IPv4 as well as IPv6 addresses in my home network. But Firefox uses always the IPv4 connection when I open a website. When I open the same website in MS Edge, the IPv6 connection is used.

I've captured the network traffic during opening a website in Firefox, which is reachable over IPv4 and IPv6. First I see two DNS queries (A and AAAA) for the domain name. Both responses containing the correct IP address, and they arrive nearly at the same time at the client. Next I can see the TCP handshake. But it's send between the IPv4 address only. No IPv6 connection was attempted.

When I run the IPv6 test at https://test-ipv6.com, the IPv6 resuls are nearly fine. Only the web browser test says "Your browser has real working IPv6 address - but is avoiding using it."

When I run the same test in MS Edge, all tests are fine.

So it seems that this is not a OS or network issue. It affects Firefox only.

What I've already tried:

• Disabled all extensions
• Created a new profile
• Used the IPv6 address of the website instead of the FQDN -> Works fine.
• Checked DNS cache of Firefox (about:networking). It contains the IPv4 and IPv6 addresses of the requested websites

I guess that Firefox prefers the A record for some reason. But I've no idea why. Has anybody an idea what could causing this?

Thanks.
