Firefox Support Forum

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.

I have not been able to highlight and copy ~ even prior to the most recent update.

Even using control/ does not work.

Really hating this.

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to (desktop) Firefox section as you have macOS.

I've noticed that when logging into various websites, a random email address not known to me appears in autofill among my usual email addresses. This unfamiliar address is under the @shanreto.com domain and shows up across different websites. My Firefox account is synced between my PC and mobile phone. Both devices are password-protected and under my control at all times, and I have only installed uBlock Origin as an extension.

Could there be any explanation other than the possibility of someone accessing one of my devices through malicious software or similar means?

when I click on the firefox icon to load it takes me to my home page, but within 20-30 seconds it loads firefox again. it is very frustrating when I.m starting something and firefox loads again taking me back to home page. I have to go down to the bottom and click off the second firefox. I don't know how or why this started. Thanks for any help.

My elderly client has enabled a “my tasks” sidebar in Gmail. He does not know how to turn it off. I have searched for an answer and have been unable to find one. Ctrl+B is not helpful and doesn’t bring up a screen where it says sidebar. Please help! He keeps asking about it and I am a caregiver, not a computer technician…

Firefox sometimes continuously adds tabs for the same site I am using. Every time I X out of one, another one pops up. This multiplies alarmingly fast. I have Windows 10.

Is there a way to turn off tracking URL fragment insertion from the release notes page when clicking "What's New" in the Firefox update modal?

When I click "What's New" in this modal (see Screenshot 1), it loads the release notes page for my current version (although it really should load the release notes page for the version it wants me to upgrade to, but that's another issue altogether), and inserts a bunch of tracking URI fragments onto the URL (see Screenshot 2).

Is there a way (in Settings, about:config, Windows Registry, etc.) to disable that fragment insertion?

I am trying to access Oracle eBS instance but when I login to the page, I get a notification as shown in the image.

After installing the plug-in and restarting the browser, when I try to run the application, I get the same notification.

I have a well hidden web server that uses HTTP. I need to download files from that server. After the newest update, Firefox now gives a warning about the website and on that warning is a button to "Allow Download". However when I click on that button, the file that gets downloaded IS NOT the file that I was initially attempting to download. It looks like it is a copy of the web page that was being displayed at the time. I noticed this behavior at work. I went home and used Firefox to connect to the server and everything connected and downloaded correctly. I went to see what version of Firefox was running. It was 124.0.2 and there was a button saying "Update Firefox". I clicked that button. My home Firefox updated to 125.01 and my home version of Firefox now also downloads the wrong file.

I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to:

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

In Chrome, I can hit CTRL+SHIFT+I to open developer tools, add the Media tab, and go to the Media tab, and I can see the codec and what decoder is being used.

How do I do the same thing in Firefox?

I want to have an automated task that sorts the incoming mail to separate folders. I have done this easily in Outlook, but Firefox's Thunderbird is different and I haven't figured it out. Any help would be greatly appreciated.

I'm having trouble with Firefox where images aren't loading on some websites, even though they display fine in other browsers. I've tried clearing the cache and restarting Firefox, but the issue persists.

Is there anything else I can try to fix this problem and get images to load properly?

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

Howdy,

Workflow: I have a firefox instance already running. I want to launch a new firefox in safe-mode to test something without disrupting my existing firefox.

Problem: I try to launch a new firefox in safe mode using `firefox --safe-mode`, but firefox just opens a new window NOT in safe mode.

I think it may because firefox in safe-mode requires launching launching from a new instance rather than attaching to existing instance.

`firefox --help` shows a flag I can use:

--new-instance Open new instance, not a new window in running instance. --safe-mode Disables extensions and themes for this session.

So I run `firefox --safe-mode --new-instance`

now I get error popup with message:

"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

Now I think what is the point of the flag "new-instance" if Firefox doesn't support multiple instances?

Regardless, how can I launch firefox in safe-mode without disrupting my existing firefox instance and without relying on creating a profile just for this?

I have two audio device plugged in. firefox only outputs to the usb devise even though i have selected the aux out on windows. all other programs use the selected audio out but not firefox

any help would be appreciated

I can no longer log into my social security account using Firefox, but the login does work on edge. When I try login on Firefox, I get the following error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The initial web site is https://www.ssa.gov/. From there I hit "Sign in", and get to https://secure.ssa.gov/RIL/SiView.action using Edge, but get just the error message using Firefox.

There is another route, which is through https://www.ssa.gov/myaccount/. Hitting either account or sign in on that page will work on Edge, but gives the same error message on Firefox.

For some reason when I opened Firefox this morning, my Firefox home page did not have any of my shortcuts. They all disappeared. Please have a look at the image attached to see what I mean.

I spent almost the entire day searching up the issue on the Internet and trying different things but they all did not work.

Look forward to your reply.

I know that it is possible, cause, in the past, I had extension doing exactly that. When I click on an active tab, Firefox just minimized it and went back to the last one I was looking at. But it was for the old version of Firefox. It wasn't compatibile with the new ver of the brawser. Can anyone can help me find some extension doing that please?
