Firefox 技術支援討論區

Last week, mid-day one day, videos on YouTube suddenly all had a warm cast --yellowish for color, cream/beige for B&W. I have researched the issue as I can. It is not my Windows night light; my drivers and PC are apparently all updated; everything is working fine. I checked to see if the same happened with Vimeo videos and it did. I'm running W10.

   Interestingly, the pop-up thumbnails one gets when hovering over the timeline as not affected; they look fine.
   One post by someone else was answered that it was a GPU driver issue; another said it's only with HD videos.
   I'm a B&W photographer and would really like to get back to normal again. 
   Any ideas?

I don't like Firefox videos showing up in my media player controls, so I turned off media.hardwarekeys.enabled, but it doesn't seem to do anything anymore. I'm pretty sure it used to work at some point, don't know when it stopped working. Even though I have it turned off, videos still appears in the Media Player on my panel, and I can play and pause them with the play/pause button on my keyboard. I have also tried disabling dom.media.mediasession.enabled, but that doesn't help either.

KDE Neon 5.27 Firefox 113.0.2

I have a 2020 Mac Mini with Ventura 13.2.1 on it. I have four virtual desktops which are part of the OS. I place various apps on the others like stocks and weather etc. to diminish clutter on screen. Firefox shows up on all 4 of them. I want it on only one desktop. Safari works on only one and doesn't show in the other 3 desktops. I have searched the net but haven't found anything that speaks to this in particular. Thanks for any help with this and I hope it's just a simple setting. Regards, Jim Stephens

I just upgraded firefox to v 113 64 bit with windows 7 ultimate. Now when I watch youtube in fullscreen there's a border around the screen. i don't use picture in picture and it isn't on yet the border won't go away no matter what I do. Please fix this or i will use another browser. i will include a screenshot from youtube in fullscreen mode look at it.

Firefox is using a massive amount of ram for an unspecified task, simply defined as "GPU" is the baked-in task manager. The attached image is after a fresh reboot, with Firefox consuming about 8 GB more than it reasonably should, with only three ish tabs loaded.

I have always read downloaded .pdf files in Acrobat. I inadvertently changed the setting to "Open in Firefox" (I got a prompt and clicked it without intending to). I have changed the preference back to "Use Adobe Acrobat" in Settings/General/Applications, but Firefox keeps opening pdfs in a browser window. How do I get Firefox to abide by my preference setting?

Years ago the find bar was located at the top of a page. The somewhere along the line it was moved to the bottom.

Some good guys realized that's a problem for some of us and came up with code to put into a .css file. That was in 2017/18

The code has worked until last week ~2023/05/15.

Now the find bar is firmly planted at the bottom of the page...very awkward place for me. Makes edge look like something to consider as their find bar is still at the top.

I've check the code and no problems...I say it appears firefox is no long allowing this customization code to be used.

I've checked the knowledge base and the same articles from 2017/18 are still there...and the solution no longer work.

Does anyone have any suggestions? I hate traversing from the top to the bottom to do my work. The find bar at the top really made it convient and easier to do my job.

thanks for any help.

The link colors are suddenly incorrect. Normally the links are blue and the visited links are purple, but now they are pastel light-blue and pastel pink. This problem is not in Edge or Chrome. I am using Firefox 113.0.1

I have tried - rebooting windows - windows shutdown, wait, restart - changing the firefox website appearance and themes (auto, dark, light) Still no solution. Any ideas? Thanks.

I have been using code (stored in the Chrome folder of my profile) to keep the 'open application menu' pancake button on the left end of the toolbar. After I updated to version 113.0.1 today, I see that button shifted back to the right end of the bar. I do NOT want it there. Can you fix it so the code will work again? Is there alternate code or some other means to accomplish the same end?

The code I've been using is as follows:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#PanelUI-button,
#customization-panel-container,
#customization-panelWrapper .panel-arrow { -moz-box-ordinal-group: 0 !important;}

/* Panel UI */
#PanelUI-button {background-position: 100% 0, calc(100% - 1px) 0, calc(100% - 2px) 0 !important;}
#PanelUI-popup {margin-right:-350px!important;}
#PanelUI-popup .panel-arrow {margin-right:340px!important;}

/* #PanelUI-quit  #PanelUI-customize  #PanelUI-help */
#PanelUI-footer #PanelUI-footer-inner {direction:rtl !important;}

Firefox very often crashes on exit. It's been doing it for some time now, but am not sure exactly when it started.

I have updated to the latest version 113.0.2 (64 bit), am on Windows 10 which is also up to date. I have tried clearing the cache.

Latest report id is bp-b9101836-487e-483f-b16f-f86620230526

Just recently, in the past day or so, when I do a search in the search box, all the results get redirected to Bing instead of Google, that I have in my settings as default. I have checked my settings, I even removed Bing from the list, and I still only get Bing results. Even when I go to Google and use their search box on their domain, I get Bing results. I did a virus scan without finding any problems. I'm stumped and don't understand why this happened and nothing I do can detect uncovers why this is happening.

Really irritating when I have to spend my time fixing stuff that is lurking in cyberspace!

I don't know if breakage is the correct topic. I keep Ring.com open to the dashboard in a pinned tab. A few days ago, I had viewed and cleared videos as usual and later returned to view new activity. The site requires logging in every 30 days and so seeing that I needed to do so was not a surprise. What was a surprise was that the login buttons were grayed out. I closed the tab, cleared the Ring cookies and cache and tried again. No luck. I wondered if there was some other setting that I didn't know about and decided to open a private window and try it there. To my surprise, it works. I'm stumped. I'll attach the raw data from the private window as a .txt file. Darn. I can only attach an image. Well, I have it available and can copy and paste it into a subsequent post if you think it would help

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

hello i have around 30+ themes and i want to delete all of themes (because i want to keep the favorite ones ) but if i delete them one by one takes time , is there any option to delete them all at once i haven't found anything on internet

Since `monospace` means something diffrent on every device, and I need consistency between clients I use `Roboto Mono` on my Website as ASCII-Art font. For some reason Firefox on Windows cannot render the font properly (view image). What can i do to fix this? The problem presists across my desktop and Laptop. See for yourself https://nx2.site/my-ascii-art (I cannot guarantee this is always up + In the future it's hopefully fixed?)

I have set .pdf files to be opened in firefox, not download and browser is still opening those in new tab and also downloading those. What could cause this problem?

Last Tuesday, Win 11 AND Firefox both updated on the same day, Firefox to 113.0.1. Ever since, my Firefox has experienced SIGNIFICANT lag time loading even the most basic of websites. It feels like Netscape 1.0 slow (yes, I'm that old). I've disabled 2/3ds of my addons to see if that would help and it hasn't. I don't know if it's an issue with the Win 11 update (KB5026372), with Firefox or some combination of both, but any help in addressing this issue would be greatly appreciated.

I'm the fan of Firefox but user experience too bad with this error I'm upload some images screenshot with error and no error with chrome browser. ++

I run Firefox on a #Windows 10 Dell laptop. I have a question and a problem, both of which involve Private Browsing.

Question: Does Screenshot work in Private Browsing? If so, how do I enable it.

Problem: When I'm in Private Browsing, my headphones aren't recognized; in normal browsing,the headphones are recognized. is this a Firefox problem or a Dell problem?

Thank you.
