Firefox Support Forum

I have Firefox open. When I click on a link in Thunderbird instead of opening the page in the open Firefox window, it opens a second Firefox window? This just started happening and I don't know what I might have done to cause it. Using Windows 8.1.

Reopening https://support.mozilla.org/en-US/questions/1412054

As you can see from https://github.com/linuxmint/linuxmint/issues/577 this issue is caused by Mozilla not caused by Linux Mint as accused in questions/1412054

Can you be honest and address this?

WILL YOU STOP THAT PATRONISING "HMM, WE'RE HAVING TROUBLE FINDING THAT SITE" MESSAGE NOW

IT IS OBVIOUS THAT IT SHOULD SIMPLY SAY " NO INTERNET CONNECTION" IT IS INFURIATING.

DO IT NOW OR I WILL KILL MYSELF.

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

I prefer to have all my previous tabs open when I start up Firefox, which means that I don't want them to close upon exit. Recently, Firefox started closing my tabs upon exit, even though:

- I tried both hitting the X and choosing Exit from the hamburger menu
- I have checked "Open previous windows and tabs" upon startup in settings
- I have not checked "Delete Cookies and Site Settings when Firefox is closed"

- I have the option "Firefox will remember history" selected

- I do not open in Private Browsing mode

What other settings do I need to change? Debra

My website has a branch that is protected with username and password. At the prompt I enter those, exit Firefox and start Firefox again. When I go to the branch and this time I do not get the username and password prompt and have free access. However, when I do shift-refresh the prompt shows. Apparently Firefox does save something that it shouldn't. Is it a BUG???

I am suddenly getting the following error message: "We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser)." Firefox is now unusable. I have searched "Settings" and can find nothing about "Content Filtering," "Shields," or "Brave Browser." Can you tell me what is going on here?

When viewing any tiktok account profile page, for example this one , the videos do not show up, and says "Something went wrong, Sorry about that! Please try again later."

Here's what i did:

1. Created new Firefox profile with default settings and no extensions
2. Visited a TikTok profile, and saw it opens as expected
3. Changed privacy.resistFingerprinting to true
4. Refreshed the TikTok profile page, and the error message shows up

I opened the console and compared and there were new warnings:

• Blocked https://www.tiktok.com/@tiktok from extracting canvas data because no user input was detected.
• Get user detail failed for getting wrong response

And 3 errors, when there were 0 before, all three read

• Uncaught TypeError: _0x5e9eb8[_0x2bd187] is null

Hello!

I have once again returned to get some help with a problem I've been encountering for a while now.

I've been using Firefox browser for years now with no problems. When I bought a new top end PC about a year ago I've started noticing that I have problems with browsing the internet. At first I ignored it, but the problem persisted to this day and now it started driving me nuts.

When I open a random new website, or a website I haven't visited in a while I get the error message "Hmm. We’re having trouble finding that site."

Then I have to refresh the page up to 10+ times, which is incredibly annoying, before it loads properly.

- my internet connection is stable, as I don't have this problem on my old PC (Windows 7, PC connected to internet with cable directly to modem) - I do not seem to have this issue with the Edge browser on new PC that came with Windows 10. I have not tried using Chrome or any other browsers - I use a Asus RT-AX55 Router, the connection to new PC is with cable. - I do not use any VPN

Some people have suggested that this could be an issue with the router's settings, but then why is the issue not present when using Edge?

Please help and advise what could I possibly do, because I have zero clue whatsoever...

Thank you kindly!

With respect,

-Jerry S.

Despiote having no problems for years this morning my access to making payments online with the Bank of Scotland was blocked. They have indicated that the problem is Firefiox not aligning with their security. can you fix this as i would prefer t remain with firefox.

I have installed Mozilla Firefox 120.0.1 on Ubuntu 22.0.4 server as a root user and can launch but when I login into another user the browser gives me the error message "Your Firefox profile cannot be loaded. It may be missing or inaccessible"

Please help me how enable Firefox browser for all Linux users

I have Firefox set to ask me where to download files that I want to download. It works for normal download links, but when I'm using my credit card company site's PDF viewer to look at a statement and I click on the download icon or link in the upper-left, it simply downloads the PDF (to my chosen "Save files to" folder in Settings). Is there a current way to change this behavior? Is this something that the website's code determines, overriding my Firefox setting?

You somehow have old, outdated information in your system. Your new browser requires me to log into a facebook account I closed 10 years ago. My password for my current account named, "VangiePangie", now opens a closed account named "Evangeline Custis". I no longer have access to my VangiePangie account with any password. So, I no longer want this new upgraded Firefox account. I want to have my old Firefox account as a default on my desktop. Right now it's an icon at the bottom of the screen, and I can only use it to open one thing at a time. Please give me back my old Firefox browser. I'll struggle with Facebook to get my password to work on my VangiePangie account. I have access to the VangiePangie account right now, because it was never logged out in my old Firefox browser and is in my Bookmarks. But if I am forced to log out, or if Facebook does a security check, I won't have access ever again. Please help me with this. Below is my VangiePangie Profile pic.

I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.

I tried to pay my Wells Fargo VISA bill online as I do every month. This morning it listed all my accounts correctly on the 'Accounts' screen, but when I clicked the options to transfer money, depending on the screen I was on, it gave a message "you do not have two accounts to transfer money from and to" (not the exact wording.)

I tried to use a different path to do the same thing, and on that screen it displayed the 'FROM' accounts correctly but the "TO" account area was blank.

I had to close Firefox, load Edge, and was able to transfer the money from the checking account and pay the VISA bill.

This has never happened before and I have done this transfer and pay operation every month for years. Something has changed in the browser and needs to be fixed.

Hello, Firefox somehow crashed. Opening did not reinstall the tabs. This has happened couple of times in the past 10+ years and I was able to recall from History to reinstall the Tabs. Now I don't see that function in the Menu. Please help. I know there is a time limit to re-install them.

I recently performed a system reset and upon re downloading Firefox I can't seem to find any of my 50+ tabs that I had open previously, all of them I need for one reason or another, history is empty, can anyone please help explain how to get them back in simple steps?
