Artifacts on webpages when hardware acceleration is enabled. Disabling hw acceleration removes artifacts, but degrades performance of browser significantly. Using hw acceleration in Chrome has no artifacts. The error is not in the hardware or driver, but in the Mozilla software. By searching on this topic on Google, it's a common error in Firefox.

The last version where artifacts where not present was: pp_name: firefox build_date: 2020-01-15 build_file: C:\Users\tulle\.mozilla\mozregression\persist\2020-01-15--mozilla-central--firefox-74.0a1.en-US.win64.zip build_type: nightly build_url: https://archive.mozilla.org/pub/firefox/nightly/2020/01/2020-01-15-21-36-21-mozilla-central/firefox-74.0a1.en-US.win64.zip changeset: c35bb210b8ae793c844bd94c1848d246bf601293 repo_name: mozilla-central repo_url: https://hg.mozilla.org/mozilla-central

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?

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 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 have set Firefox as my default browser. I can open it using a shortcut on my desktop. However, if I follow a link from an email, it does not open in Firefox. How come?

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

Anyone know why this is happening and a solution?

Each time I connect to the Sam's Club website I get a popup box that says "Let us know your human (no robots allowed)" even before I try to login. There is an "X" in the upper left corner of the message that I can click on twice and the box goes away. I then can click login and my password saver fills the boxes at which time I get the same box. I click again on the X and a message says there is a problem, try again later.

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!

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.

Hello firefox team, recently my firefox account was disconnected then i have refresh firefox and re-signin to my account i saved many password in my firefox password manager after sign in my all password was removed. sync system in not restoring my password please help.

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.

As long as I have an incognito window open, Firefox will reopen old tabs everytime I open a new "regular" window, even if "Open previous windows and tabs" is unchecked.

Firefox used to open the bookmarks to the left showing all the bookmarks, ever since that last update not the go right and aren't even the bookmarks I want, how do I change it back

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

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

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.
