Firefox Community Forum

Ever since the last big update, there have been at least 2 dozen videos that I can't load in Firefox that immediately load in Chrome. I've had to start using Chrome (which I really don't like) for all of my classes that are video based because the videos aren't loading in Firefox. Does anyone else have this problem? What can I do to watch videos in Firefox?

since fire fox update i keep getting log in errors as below with a different number

You don't have permission to access "/secure/account/Login" on this server.

I'm using Firefox 115.15.0 ESR with a MAC M2

When I visit jsonviewer.stack.hu and paste data into the viewer I get the following error:

TypeError: netscape.security.PrivilegeManager is undefined

Please type: "about:config" in your address bar. Then filter by "signed". Change the value of "signed.applets.codebase_principal_support" to true. You should then be able to use this feature.

As config is sensitive area of the settings can you guide through this problem with a fix? Thanks bcoleman@sympatico.ca

Hello, I forgot the password of my firefox account. After I changed the password and entered the account, all my account information is lost. Please help me to get my account information back.

Edge and Chrome directly open embedded government pages, such as https://www.nifc.gov and https://hazards.fema.gov/nri/map, that "Firefox Can't Open." "To protect your security," Firefox requires each to be opened in a new window. This is an incentive for users to switch to Edge or Chrome and stop using Firefox. All .gov pages should be safe to open even if they do not "utilize x-frame options or a content security policy to control whether other websites can embed them."

So recently on the latest Firefox version 128.0.3 (64-bit) I have seen blank pages very often. Be it me trying to search for something using google or opening results of such searches, my Firefox just displays a blank page. Sometimes it's the fifth tab, sometimes it's the second tab - but it has happened a lot within the last week. At first I thought I might be running out of RAM but that doesn't seem to be the case because next tab opens and plays nicely as seen in first screenshot. I'm running Windows 10 x64 and have no plans on going Windows 11 ever, but this is just silly.

Restore gadget screen width to default 1/3 of screen, not 1/2. Gadgets are now too wide for easy reading, they were always 1/3 of the screen until recently. Did I inadvertently make that change, or was it part of some update?

After your an update some weeks ago, I have not been able to access my bank account using Firefox. Got some advice from support from the bank, but since I have an US version, the labels to be accessed differed, and were not compatible with the advice. Presently using M Edge, which I of several reasons don`t want to. Any suggestions?

No matter which way I try to close it, Firefox Will Not Close and stays open 24/7. I do not know how to get this browser to close! Firefox continues to freeze and shut itself down, but NOT close out. I do believe it is a security risk. Thank You for your help.

Everytime i fullscreen a youtube video my graphics card starting loads at 75% and above. Its only happening in Firefox browser. Dont know the core reasons, only just assuming it might be some bitcoin miner bullshit. Wondering is there, maybe, any other particular reasons of this happening?

I've been experiencing issues with my firefox browser (most updated version 129.0.2, running on Mac Sonoma 14.6.1). Seemingly at random times, it decides to start displaying weird symbols all over. The settings, the menu, the text on webpages, it all reverts to these weird symbols. Restarting the app and my laptop works sometimes, but only for a little bit of time then a day or two later this starts to happen again. I've tried to look at other help articles but it doesn't seem to be a font thing, it's becoming really frustrating and I hope there's an easy fix otherwise I won't be able to keep using this browser as I share my screen for work often.

Although the tab for "Autofill Payment Methods" is checked within the Privacy and Security section in settings, when I click on one of my various saved credit cards, autofill doesn't seem to happen anymore when I'm trying to make a payment. That applies to all of my saved credit cards.

Why, and what can I do about it?

Hi again,

so, in my other question I was reminded about Browserleaks and while I was there testing TLS I also tested Canvas and it said 100% unique which I was surprised because I have the Enhance Protection in FF in "Custom" with both fingerprinting options selected and in "in all windows", plus CanvasBlocker.

100% unique is not good, right? That's what I thought at first. But then I remembered, CanvasBlocker rotates settings all the time, so even if my fingerprint is 100% unique it's also changing all the time which means "they" can't identify me (supposedly). Then I also thought "actually it might be better than not 100% unique because in that case I might have more issues with websites thinking that it's someone else trying to access my account". But then I thought "although if it's 100% unique changing all the time it's also like if it was a different person".

I deactivated CanvasBlocker and tested again and it was also 100% unique. Then I reactivated CanvasBlocker and I deactivated FF's anti-fingerprint. Again 100% unique. In other words, I don't see a way to see what is the difference between using CanvasBlocker on top of the native FF anti-fingerprint. That's where you can help :)

So, questions.

1) can you tell me what exactly does FF block about fingerprinting? And, does it rotate settings like CanvasBlocker so that this "100% unique" is not actually a real issue because it's different every time? Or is it a bad kind of 100% unique in that case?

2) what would create less issues of websites thinking that I am not me? A rotating 100% unique, or a not 100% unique (in which case, how to I achieve that, considering that neither CanvasBlocker nor FF's anti-fingerprint nor both together can do that?).

Would you say that having a VPN with own DNS which block tracking on a domain level, plus AdGuard with all possible filters, plus FF's Enhanced Protection in "Custom" with all at max, plus CanvasBlocker, is a good combo? Or what could I improve to reach a good balance of not being tracked/fingerprinted, not being blocked "because I am not me", reasonably light resources usage, and reasonable browsing speeds?

I used uBlock Origin previously because it's lighter on resources and it triggers my laptop's fans much less than AdGuard but it doesn't block (not even with element picker) some annoying things of websites that I visit often. In case you wanted to recommend that :)

Thanks!
