Firefox-Hilfeforum

Every once in awhile i get a second Firefox icon pinned to my taskbar and also a second listing for firefox in my programs list. If i try and delete the extra version there is only one listed in the control panel. Has anyone else seen this? I am running Windows 10 Pro.

All of the sudden I am getting an "Acess Denied" message from Quickbooks online. The error message is immediately after I type in my login ID and hit enter. It doesn't even let me get to the password input screen. This started on Thursday afternoon, but was working fine Thursday morning.

I have a 30-day free trial for DeepL add-on (and enabled it in Firefox). I tried to use the extension when I visited a Russian website and clicked DeepL and "Translate this selection" and nothing happened. The webpage wasn't translated. Do I have to be a "Pro" user to use DeepL? If not, how do I get it to work? I'm using Firefox 122.0.1 version and Windows 10.

Firefox is my go to browser, pretty much the only one I use. I have logged into the akc.org webpage 1000s of times. Now, only on your browser (I tested two others), I get a blue button with a padlock image that reads "login to AKCAD," the I get sent to microsoft. I made sure my microsoft account was not hacked and it is not, and I logged out of it. I still keeping getting this; I added the succession of what happens in the attached images. Please figure out what the issue is. Thank you!

I just had to reinstall Firefox because It keeps trying to take over Firefox. I had to delete Cert9.db., I found in my Profile.

How would I solve this problem permanently without having to go back and troubleshoot over and over again?

As of today every time I open a FF window it has a sidebar for history. I do not store history and need to stop this. I do not want to close it i want to disable this annoying new function or I need to delete FF and choose a different browser.

Firefox is my default browser; however, when I click on a link, MS Edge opens it instead of Firefox even thought Firefox is already opened. How can I prevent that from happening?

My system recently slowed considerably. When I checked what was happening, I found there were up to 14 Firefox 'windows' showing in my Task Manager, and collectively these 'windows' were consuming over 25% of the computer memory (650+MB) even with Firefox just opened as the initial browser screen; no addresses etc had yet to be added. I've followed many of the troubleshooting suggestions, but to no avail. I have not reset the browser as yet as I need to understand the root of the problem

Thanks in advance for your assistance Duncan Hodder

Firefox is now opening two windows at startup: one that has my previous session (which I always prefer) and one window with one blank tab. It used to open only the saved session. What can I do do change this. Thank you. (I have Firefox 122 version)

Hello,

Recently I realized that the vast majority of my passwords were no longer present in the Firefox password manager. When looking at my profile's logins.json file, they are all present, yet only the last two are visible in the password manager itself. I've tried refreshing Firefox, restarting my PC, and creating a new profile and copying over both the logins.json and key4 files to it, yet the issue remains. Is there a way to decrypt the logins.json file using both it and the key4 file so that I could import into Firefox as a CSV? Thanks in advance.

I've been playing online-games on "https://www.1001spiele.de" for several years now. After the last FF update they would not word. Even the buttons under the game area are greyed out and does not work. Refreshing the page seem also useless.
