Firefox 技術支援討論區

I'm trying to watch videos in Firefox. Youtube works but Xvideos does not. Firefox pops up a window asking me:

>> "Opening xvideos"."com ###.mp4". >> which is: MP4 Video (16.4MB) >> from https://cdn77-vid.xvideos-cdn"."com >> >> What should Firefox do with this file?

My only choice is: Open with Windows Media Player x86 (default)

suggestions?

I'm running Windows 7 Firefox 76.0.1

Thanks!!!!

Is there a preference in about:config to fake or simply block websites from reading the font-list of my operatingsystem? I think it is pretty ridiculous anyways that websites can access this information since it has nothing todo with the webbrowser visiting the site but going beyond to spy on information that i consider private.

Same question goes for audio-readout, is there a pref to fake or block?

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

I am in the process of moving all of our passwords into 1Password. However, I discovered that my wife has her Firefox set to auto login, but can't remember her user name and password. So, although she can use it, she can't change update the password. The fact that on setup, auto login is the default makes this doubly frustrating. So, is there any way to get to the password?

How can i hide my display/screen resolution from websites? I use Firefox in windowed mode not with my default screen size but websites know my default resolution. This can be used to identify my pc. I dont want that for privacy reasons like tracking and adverstising. How can i prevent this? I found many threads/posts about this in various forums/websites. They are talking about Tor Browser and that websites can identify you if using full-screen mode. But as i said, im using Firefox not Tor and while im using windowed-mode websites still know my default resoltion. I tested this on https://whoer.net/

Another question, how can i restore the default window size in Firefox?

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

Hi

Running Firefox 71.0 (64 bit)

Well seems Firefox has been messing this up again.

Anyone have the new work around solution to get my tabs back on the bottom again. They were fine this morning then shut down and went out to lunch and when I came back they were back on the top again after months of being where I wanted them below my bookmark bar.

Thoughts on this?

Thanks Dave

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.

Hey folks,

i am facing issue with high CPU usage on firefox in completely different process other as visible in task manager than my actual process for firefox. is there something wrong with firefox or my system.

This separate process uses more than 60% of my CPU (AMD Ryzen 5 4600). If I close that process in the task manager nothing happens to my current firefox process and i can use firefox normally.

But everytime this separate process starts my system fans ramp up and CPU temps peaks to 70 degrees celsius. and i have to end that process to make it run normally. Thats a quite annoying process to do every time.

I am able to recreate this separate process by:

1. 1. Plug my system for charging
2. 2. I was working offline and connect to internet

both the times the separate process automatically starts and uses very high amount of CPU. I even left my system for 2 hours to keep that process running and complete whatever it was doing. but nothing happend. It continued to run for 2 hours also.

Please find a solution for this. I have already tried solutions provided in the forum:

• Restarting firefox
• Refreshing Firefox
• Enabling hardware accleration
• Clearing some user profile data
• Completely uninstalling firefox and deleting the residual files then reinstalling etc.

but nothing worked.

hello

1) I've been trying to change the console colours for the web developer console using userChrome.css, but I have failed. I want to set the background for console.info text to be light blue while the text color to be bold dark blue font. I would like to have it only in light theme. Also I would like to change the font size of the console for both themes.

2) Is it possible to change the folders of bookmarks to yellow. I read there are SVG. I tried to solution that are meant to change the folders to yellow, but failed. Can someone point me to a dummies guide for a solution.

The first one is the more important issue.

Thank you in advance

All of a sudden today I am unable to connect to the Microsoft Community https://answers.microsoft.com/en-us/ and to my Microsoft Account https://account.microsoft.com/privacy/. I can connect with Edge but not FF 95.0. It seems according to the MS Forum that I am not the only one with this problem. Please see screenshots of what I and others are getting.

Hi. Starting somewhat recently, Firefox has been getting in the way of me downloading certain PDFs which I know to be fine but which it thinks are insecure or a security hazard. I'd like to disable this security "feature" permanently. How can I do this? Thanks!

Yesterday I went to my history to locate a prior site I had visited. There was only 1 site in history, which of course surprised me, and it was to CapitalOne.com/link accounts. This is my credit card company. I removed Firefox from my Macbook and then re-downloaded Firefox and installed. Nothing has changed. My settings are correct, meaning that I should be able to have sites visited in history, yet only the one site populates, and I've been to a lot of sites today....the credit card/link accounts site is the only site that is in history. You can imagine how nervous I am right now about doing anything on line. I sure hope that someone will help out here.

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

Hi, In these last days, I deleted a bookmark folder or something by error. Then I found some daily backups, and I restored from the last one backup.

The next issue was that the following daily backups have less bookmarks, and doing some testing, it appears the Daily backups, now, are not including "Other Bookmarks".

It has less entries from now on.

I want to know if there is a bug, or something changed by itself. How can I fix that?

Thanks

In most standard Windows applications, the title bar and tab colour follows the default Windows settings, e.g. (in my case) the title bar and tab colour of active application windows is blue. This is true even in Thunderbird. Since FF 89, title bar and tabs are something between white and light gray, which is extremely user-un-friendly. FF developer team should return to the previous colour scheme. Yes, I know the circumstances of free software but this is NO excuse to alienate millions of users. Developers that change fully functionable software just, well, just to CHANGE it should consider that they are doing WRONG. Could anyone tell them? I am just user, not developer and I am not willing to learn developer tools like BugZilla just for this simple guiding principle.

Hello,

I've spent several hours today trying to fix FireFox slow start up on my system. After start up (about 2 full minutes), everything works normally. The hardware is an ASUS A88xm-A MB, A10-6800K processor, 16G DDR3, runs OS and programs off an SSD. I worked through all the slow startup suggestions, ran memtest (0 Errors, 1 Pass), disabled all add ons, (even the OpenH264 video codec (I use the onboard HDMI, no graphics card)), turned off hardware acceleration, etc. When starting in troubleshoot mode, less than 30 seconds, (acceptable), but I really don't know where to begin with the "More Troubleshooting Information" when I look at the table generated by it. There have been no other problems to date with the system, and the long start-up time began with 20.04 Ubuntu (about a minute), then got worse when I upgraded to 22.04 to try to solve THAT problem. Currently running FF 104.0, and the update page says wait for a distro update if that is how it was installed. I believe 104.0 is the latest Linux 64b version though. All updates to the system are done as soon as I'm notified of them. there have been none since the upgrade a few days ago.

Any suggestions? Gotta get some sleep now... TIA, Dave
