Firefox 技術支援討論區

Hi there,

I have a laptop running Windows 10, plus the latest version of Firefox. The laptop has a built-in webcam. I have also connected an external webcam via USB. This second camera is better quality and preferred, I visit a web site. When I first activate the camera, I am presented with a dropdown of available cameras. The USB camera appears in the list. All is fine. I instruct Firefox to "allow" this camera to be used. (first image) However, after a short time, less than a second, the same dialog is shown again, this time without the USB camera. (second image) There have been no actual hardware changes. I can then click "allow" again and the *integrated* camera works, i.e. not the desired camera. So, two questions, really. First, what just happened? Did Firefox try to control the USB camera, find that it couldn't, and redisplay the dialog showing only the "controllable" option? Second, my desired endpoint here is for the web site to use the USB camera. How do I achieve this? I can easily do this with Chrome but I like Firefox. TIA.

Hmm. Kami kesulitan menemukan situsnya. Kami tidak dapat menyambung ke server di www.thishabboforum.com.

Jika Anda memasukkan alamat yang benar, Anda dapat:

   Coba lagi nanti
   Periksa sambungan jaringan Anda
   Periksa apakah Firefox memiliki izin untuk mengakses web (Anda mungkin tersambung tetapi berada di balik firewall)

So basically Firefox updated itself yesterday. And since it did I have not been able to use the webcam (which I need to use on a daily basis in Google Meet). I tried using Chrome to see if it worked and it did, I just prefer using Firefox.

But then I started looking for information that might help and I found out about the New Profile feature which I did not know about. I made a New Profile and when I tried using the camera it actually did work there.

What am I doing wrong with the original profile? I have not changed any settings, is it possible it just changed on its own? And how can I restore it to how it was? I already tried re-installing Firefox a couple of times yesterday and nothing worked. I uninstalled it and installed it back again and the problem persisted. I deleted cache and cookies and still the problem persisted.

Please help! Thanks a lot

Firefox deleted a bunch of my stuff- customization, bookmarks, settings, add ons and most importantly history and cookies, annihilating my browser game save which I had for over a year.

It did so without my knowledge or permission, and I want to know why that happened, and why can't I recover the most important stuff- my history and save from the game.

I copy and pasted all the files inside "old firefox data" folder and it brought back my bookmarks and add ons, but it did not recover my settings and history.

Putting everything back to how it should be will take me ages, and I won't be able to find some important websites I usually would access by history.

So, can someone tell me, why firefox just did that without my permission or even knowledge? And if there is a way to bring my stuff back, because I'm really not in the mood of setting up the whole browser after I've already done so when I decided to switch to it.

Thank you for any help.

About three months ago, I changed the AO3 site skin to the Low Vision option, because I wanted to see if I could fix the then minor issue of not being able to see bold with my screen-reader, NVDA, when reading fics on the site. Some of the bold I knew to be there because I had personally put it in.

When I changed the skin, I was dismayed to find I could not only still not see bold, but I could no longer see italics with NVDA either. The AO3 sidebar menu was also tucked away behind a dropdown button, but I could open that up and get to the controls, so I didn't mind that so much. The formatting, however, posed a real problem, since italics are used for, among other things, emphasis, telepathic speech, and the speech of Pokémon in fanfics featuring humans who can understand Pokémon. So I definitely wanted this problem fixed.

I thought I could simply change the site skin back, but to my further dismay, switching back to the Default skin did not restore my former view of the site's pages. I began trying other things, seeking advice from other tech-savvy acquaintances after I'd exhausted all the possible fixes I could think of to no effect. Here is a list of everything I've already tried:

• As mentioned before, changing the site skin back with the buttons on the site
• Soft/Hard-Refreshing the page.
• Logging out of and back into my AO3 account to artificially end the session.
• Restarting the computer, and NVDA, by extension.
• Disabling each of the three extensions I have in Firefox, just in case one of them had caused the issue.
• Viewing the site while logged out to see if that made a difference.
• Cleared browser cache, and when that failed to help, also cleared specifically the AO3 cookies.
• Created a clean Firefox profile with no settings changed and no extensions added, pasted url of one of the pages I was using as a test into the address bar. Still no formatting visible.
• Viewed page in Incognito mode.
• Briefly thought I had a solution when I found the Page Styles submenu in the View menu, set the page to No Style. Got my old sidebar back, but not the formatting, and lost even that change after a refresh. Not ideal solution.
• Downloaded the portable version of Firefox, opened it and pasted in a url again. Still no formatting.
• Reluctantly, opened AO3 in Google Chrome. Could see all the formatting with NVDA when logged out, and when I logged in, could still see the formatting.

I also discovered Reader View while testing some of these things, and this allowed me to read the text of a fic or chapter with all its formatting, but that view doesn't include the Author's Notes, or the comments, and that sacrifices some of the nuance of those because I don't see the emphasis on any words/phrases without the formatting.

I have contacted the AO3 support team, but they are just as confused as I am and don't know what could have happened. They say they haven't changed anything on the site that they could pinpoint as causing this problem.

I have tried asking on the BlindTech email list I'm subscribed to, which is where I was given the link to Portable Firefox, but I have exhausted all their ideas as well, some of which were included in the above list.

Now I come to you. Please, if you can shed any light on what might have caused this problem, I would deeply, sincerely appreciate it.

When I download a pdf file while using Firefox, the file won't open. They will open if I download them using a different browser. I've scanned for viruses, malware, etc. and nothing is found. I turned off "block popups"

How can I fix this?

My Red Vector / Convergence LMS that I use has recently become very slow when searching or saving within the system. Does Mozilla need to make changes for this Site ? If not then I will have to go to Chrome. It works fine in Chrome. Please respond back. Thanks

This question was previously posted: "How to DISABLE the back and forward arrows that now come up on the left and right sides of the Firefox panel." There was only one answer but it didn't address the actual issue. It's too easy to inadvertently go back a page or two which usually screws up something I'm working on. Someone added these annoying arrows, there must be a way to remove or at least disable them. PLEASE HELP!!!!!

My Firefox browse is frequently unable to log into many financial sites, most importantly my Scotia bank. this happens almost every week or 2 and I am forced to use Microsoft edge or Chrome which log in fine. This can sometimes happen as frequently as once a week or it will go 2-3 weeks without problems. Is this a Firefox issue or are 3 banks, 1 credit union, Credit Bureau, government and medical sites all to blame?

did the MS10 update a few minutes ago - ''Quality Updates (50) 2023-01 Cumulative Update Preview for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 22H2 for x64 (KB5022478) Successfully installed on 1/26/2023 2023-01 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5019275) Successfully installed on 1/26/2023 2023-01 Update for Windows 10 Version 22H2 for x64-based Systems (KB4023057) Successfully installed on 1/26/2023''

after, could not "run" my firefox reinstalled firefox x 64 still could not run actually, it did not even build the firefox folder i thought it would under c:\program files/mozilla firefox so, i created folder there called Firefox2, and copied the firefox installer program there, and executed still, no "build" in folder, but has a Firefox icon, but still wont execute

firefox is my default browser ! Thanks for any suggestions mike

The queries don't even reach the server. On Windows 10 I don't have this problem. Both have the server parameter set to https://192.168.1.x/dns-query/. I have tested versions 102.7.0esr and 109.0.

When using a site with a drop down feature, the options are not showing up. Canadapost.ca allows you to search for postal codes and will provide options as you put in the address. This feature is not working in Firefox but does work in Microsoft Edge.

I have a video of the issue which I cannot upload.

I saved my login information for several accounts in the Firefox (desktop) built-in password manager. Then I got Firefox on my phone, found out passwords aren't protected as well on the mobile version, so I turned off sync then removed them from my phone. Later I turned sync back on thinking that it would just sync my tabs and, if it did do anything with passwords, it would copy my logins from my computer to my phone instead of removing them from my computer. That was yesterday, today I needed one of those passwords (randomly generated so I don't remember it) so I went to my saved logins on desktop and they were all gone. Is there any way to recover them?

A post having the same problem as I do.

Hi,

Recently I got a new gaming monitor (Asus XG27AQM, 240hz, 270hz overclock by factory). Evey time I boot up, open Firefox, and start Disney+ site, my monitor would shutdown after showing white noise screen for like quarter of a second.

Then after reading an article (link attached) with the same problem that I have, I tried to replicate the problem using Brave Browser, and there was no issue there. Then I uninstalled Firefox using an advanced uninstaller to remove all traces of files, keys, and others, then reinstalled a clean new Firefox, opened up Disney+ site and the same problem happened. The only solution that I don't know how to apply is how to reset Firefox completely, but I doubt it would solve it since I completely uninstalled & reinstalled it without leaving any traces back.

The following can be removed from being the cause of the problem, since I've double checked them and confirmed them in all ways possible: Monitor's Settings, 270hz overclock, DisplayPort, Windows 10 Pro settings, gaming related settings, power settings & updates , Graphics Card.

I've attached a link for a post that's describing the same issue that I'm having, just to save some time and maybe provide more description to my issue. I would highly recommend viewing it since it contains an answer to my issue which could be the right solution.

Thanks a lot in advance, I would highly appreciate any help. Have a great one.
