Firefox Community Forum

Smaller adblocker ultimate advertising icon appears on most screens. It's annoying and typically in the way. I tried adblocker once but disabled it months ago and removed it today. The ad for adblocker ultimate still appears in the lower corner of most pages. The icon and the Expanded flag is (opened) are both attached below.

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

When I open Firefox on my new computer all the bookmarks are showing at the top. I only want my default bookmark toolbar to show. The only solution I could find was to drag it into the toolbar area.

Hello Before I reset my PC some months ago, I almost never had to Login to sites, as the kept me logged in. This no longer happens, and now I frequently have to Login to eg. my Google account which needs third party autho and all sorts. It is rather annoying having to Login to Google every time I close the Window.

I do not have this setting on: "delete cookies and site data when Firefox is closed" I do have this setting on: "Ask to save logins and passwords for web sites"

It does save my Password and autofill, which makes it easier. But it is still annoying, that I have to login to everything every time.

I have tried reinstalling Firefox, to no avail.

Please Help

Just today a web based TV show has stopped playing, the circle spins for a moment (as if it was loading) the circle then just vanishes and nothing plays.

I am running Win 11, I have successfully had the video play in Edge and Brave.

Firefox however is being stubborn and refuses to play

New Firefox is making me angry everytime I use it. New tabs are doing what they want, they never open near the site that i'm watching. Sometimes they open in the middle of other tabs, sometimes at the end. That is so problematic and frustrating that i would download an opera if i can't change it. I use about 90 tabs and that's the way I'm using Internet, I won't change it. I have searched in settings but there is nothing. Old mozilla haven't done this. Can someone help me?

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

I really appreciate the container tab option for my browsing, as it affords me more privacy and I am a stickler about my privacy. However- I have been having an issue with links that I am attempting to open in a specific container that will load, and then immediately reload into the tab without a container. This has happened several times. The most recent example is that I clicked on a link from FB, a site I tend to avoid, and specified that I want it opened in a FB tab, as I don't trust them not to track me beyond that. However, the link loaded in the FB tab and immediately again with no container whatsoever. There was no request, no warning that I had set up the "multi-account container" and did I want to use it in the designated container... nothing. This has happened with links before as well.

Characters dissapearing, missing, garbled only in Firefox. Seems to be ok in troubleshooting mode. This only happens in Firefox so it appears to be isolated. As you hover over links is when it happens the most. I have the latest version installed and was just loaded on a new system.

Since updating to 121.0.1, only the top edge of the tabs in my menu bar are visible (see image). I tried reinstalling, restarting, and switching to a different theme. Any thoughts on why this is or how to fix it? Thanks in advance!

I reset my pc and don't remember password I have logins that I don't have saved anywhere else on this account so I don't wanna reset it normally I only was able to login with login through google and I can prove I actually own the account in anyway other then password cause i changed it a bit ago and just can't think of the whole thing

When I am trying to access a photo library for Bing Wallpaper photos I am blocked by Cloudfare error 525. I can using a different browser (MS Bing; Chrome; DuckDuckGo) and it works fine. Only errors out using Firefox since last two updates.'

I visited Twitter and Facebook looking to contact Graham Hancock. I had to signup. But now everytime I open my browser ---- Twitter and Facebook automatically open up. HOW DO I GET RID OF THESE 2.

When I want to go to the NY Times, and i type "nyt" the address bar automatically populated with the rest of the URL "nytimes.com". When I do the same thing with gmail and "gmail" it runs a search on a search engine instead of completing the rest of the URL.

Why would it do this for one website and not another? How do I fix this, I use gmail all the time so its a bit of a time waster.

Thank you in advance for your help!

The removal of the download status bar at the bottom of the browser is a major UI failure and this feature needs to be returned.

I spent 30 minutes attempting to download/extract a settings file from an Addon until I noticed that Firefox was silently downloading it to my Downloads folder without any notification that it had started or completed.

The download bar was a known solution for this; The bar itself did not obscure the current webpage, provided immediate feedback on download initiation, progress, and completion. Provided quick access to open the file(s) or find options about the file(s), and the download bar could be dismissed quickly if the vertical page space was required/desired.

The hidden download tray is a horrible design idea, makes it difficult to see if your downloads have started successfully, when they have completed, and how to access them. Additionally, the introduction of 'hint' popups to support this feature actively obscure the webpage you're viewing, making them dramatically worse than the download bar, which left the page completely usable and only required a few pixels of height at the bottom.

This is a major design flaw.

I am having a problem with my Firefox homepage. There are several things going on like the red, yellow and green dots on the left side of the menu change to light dark. Some of My Bookmarks appears twice and one was added. I did a Refresh and troubleshooting but to see if my home page would go back to normal but it did not. I think I have a bug that is causing these changes on my Mozilla Browser. I need to get the browser back to normal.
