Firefox Community Forum

When attempting to log-in to a website (Credit Karma) I have previously visited many times with FireFox, I was presented with something new - something I eventually have come to believe is the Canvas Permission Prompt, as described here:

 https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting

Not knowing what the prompt wanted from me, I foolishly clicked on the "Don't Allow" button feeling that was the safest thing to do, but realized only as I was clicking the button that the "Always remember my decision" checkbox was default-checked. And as I feared, now whenever I go to the site login page, I am unable to click into the User Name or Password boxes to fill-in my info and nor can I click on the "Log In" button. All other links on the page still seem to work, though.

I have attempted these possible fixes in the about:config list: 1. privacy.resistFingerprinting - I had previously set this to True as per suggestions from several YouTube posters expounding their opinions on safety and security and have been operating with this setting for many months. I tried setting it back to its default False state and restarting FireFox, but the problem still persists. 2. privacy.resistFingerprinting.autoDeclineNoUserInputCanvasPrompts and

   privacy.resistFingerprinting.randomDataOnCanvasExtract - These two looked interesting because of the "Canvas" text and I found them to be set to their default True values since the installation of FireFox.  I have individually set them each to False followed by a FireFox restart, but still the problem persists.

So how do I get the Canvas Permission Prompt to be reset/restored so I can use the login page to get to my account.

Thx

I am trying to run firefox unofficially run a windows vista Virtual Machine using the Windows Vista Extended Kernel, but is says the the dll "api-ms-win-core-sysinfo-l1-1-0.dll" is missing. It did this a couple of times and i was able to copy over all other dlls, but after placing this one in Windows,System32,Program Files/Mozilla Firefox and SysWOW64 and re-registering it, it still gives me an error. Could you please provide the location of the required dll since it can't find it.

The “find the next” ＆ “find the previous” icons are invisible when I tried to search some words in a PDF with the build-in PDF viewer.

The icons are actually still there, and worked well when I clicked them, but just being invisible as the image shown.

Does anyone know what happened, and how to fix it?

Thanks a lot.

Ik heb een vraag ?

Als ik mijn Firefox twee x open, en dan weer beide sluit zijn de volgende x als ik mijn Firefox open al me tabbladen in eens weg en moet ik ze opnieuw vast zetten.

Hoe kan ik het zo in stellen ook al open in 100x Firefox en weer sluit dat hij de Tabbladen onthoud en dat ik ze niet steeds opnieuw moet vast maken ?

Met vriendelijke groet

Whenever I open Firefox on my Windows 11 laptop, a notification panel appears bottom right highlighting a news article from cordbusters.co.uk. I don't remember subscribing to this service and I can't turn it off. I can ignore it, and it times out after a few seconds. I checked addons and extensions but searching for 'cordbuster' in Settings gives no results. Running an internet search for cordbuster gives results for other sites quoting cordbuster but nothing suggesting a service provision. I am a long-term user of Firefox on phone and laptop.

For the last month or so I have had problems with Firefox using too much CPU, too much memory. This is not long after I have restarted. It soon gets so bad that there is a 3-6 second delay in anything I do. At this point I am going to have to stop using FF as it is too disruptive. Cannot place any other system changes.

Hello,

When I close Firefox after the last update (current installed version: 112.0 x64 Windows 10), Firefox creates almost 200 processes (in the latest case 177), each using from 17 MB to 65 MB RAM (except one that is using over 200 MB - I guess the main one) using 100% CPU for about half a minute, and in that my PC is unusable - everything hangs. It takes a bit more time to close all of them.

Any ideas what could be wrong and how to fix it?

Thank you.

To whom it may concern, When I use Firefox I have issues all the time with popups like chat windows or under yahoo finance I persistently cannot open the conversation link on a stock; And the inability to open website content completely when selecting something within the website. I am about to stop using Firefox because when I use Microsoft Edge or Google Chrome I never have these problems. I have even seen that many insurance Co's websites specifically say to use those other browsers and not Firefox. I have tried to adjust security settings without any success.

Thank you for your time in this matter.

when i click on a firefox tab it opens in a new window - how do I stop this?

Already tried going about:config and changing 'browser.tabs.allowTabDetach`, and set its value to `false` and it is not working. Advise.

When watching videos on streaming services (e.g. Netflix) a "1.0" is placed in the center of the screen. How do I get rid of it? (I don't want it ANYWHERE on my screen.) Thank you for your help.

Hi I'm not sure what happened but when i turned on Firefox on my laptop I needed to sync but I couldn't remember my password so i set a new 1 and now i can't get any of my saved passwords which i had help can i get them back after i created a new password on Firefox

I have no audio on firefox. I have audio in other programs but not firefox. I have tried different websites, and yes I did double check to make sure the website was not muted, and still nothing. I have cleared the cookies, and history. I have restarted firefox. The recommenced performance settings, which in my search for answers says should be turned off if you don't have audio in firefox, is already turned off. I had this problem before and forget how I solved it but it seems firefox just seems to randomly shut off the sound.

Firefox is running 23-30 apps in the background and consuming about 30% of CPU simply when it is open. Is this legit or is something else going on? Reduce number of apps running in the background so that less CPU bandwidth is utilized.
