Firefox 技術支援討論區

I've blocked Autoplay (Audio & Video) for *all* Web sites via the settings menu, but videos still continue to play automatically (abcnews.go.com, for instance).

I went to config:about, and made all the suggested changes I found in Mozilla support. Autoplay seems to be blocked now, but at the expense of Firefox going into an endless loop trying to load and play videos. While in this loop, Firefox is eating up 20% of my CPU sources, which comes to close to making my PC unusable.

I have Firefox 109.0.1, 64-bit.

This has been a chronic problem ever since I've used Firefox. Someone needs to take a MUCH deeper dive into why we can't block autoplay.

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

using firefox version 109 and my internet down load manager no longer works, it works in other browsers but not since updating firefox. not sure if i was successful in posting this request prior to this one so will give it another try. thanks

So, for awhile now when I go to some sites, the screen suddenly starts flashing, then it jitters and turns some light color (like a light green; not blue screen, not black). If I guess where the "X" is to shut down the tab that has the video, I can end this. Often, like on youtube, I find the problem is some ad video that was playing. The rest of the site is ok. But not always.

One site I wrote down a few days where it happened: https://www.nbcsports.com/philadelphia/eagles/eagles-face-giants-2022-playoff-opener?cid=sm_npd_rsn_phi_fb_mn&fbclid=IwAR3rGUEa0W8fElrzCWANSIUpti9VKlbn0iHyvcFsviajYExo5tcRSyWBJXA

scroll down to video and everything blinks, becomes unuseable

It happens in lots of places, though. It is not per se a YouTube problem or just a problem at NBCSports. I shell out to MS Edge, and it seems to handle everything fine, so I'm assuming at this point it is a browser issue.

One last point: after this happen the screen display is degraded even after I manage to shut down the offending tab or video. It takes a Log off/log back in or reboot to fix everything. The degradation takes the form of making the screen look a bit like a pointilist painting, although that's an exaggeration.

FF 109.0.1 64 bit Windows 11 NVidia GeFORCE RTX 3060 running studio driver 526.98 (I have switched periodically from / to their gaming driver, which doesn't seem to matter)

Any help, appreciated.

My extensions take up a lot of space in my toolbar and I'd love to hide all of them. However - every 'solution' to the problem tells me to right click the extension straight from the toolbar and click 'Hide from Toolbar'.

I do remember this option existing, however I couldn't find it since last update and I'm assuming it was removed. Is there any way to use it again?

^ (Small note, It would also be lovely if I could add them to the Extensions add-on in the toolbar, as that would really be a better use for it other than overflow)

WHERE IS MY BOOKMARKS TOOLBAR??? Every time I update Firefox (now 109), I end up with all kinds of problems! NOW, I can't see my bookmark toolbar. All the help articles tells me how to show it or how to bookmark a page, which I already did multiple times. But this issue is never solved. If I can't get this resolved, I'm going to MS Edge.

I am trying to get set up for video visit with my Doctor for Monday morning and when I try to test it I get this message. This action was blocked by your popup blocker. Would you like to open the link? How do I fix this? Thanks

so, my computer is getting old, and because of that, it's slowing then. Firefox isn't helping much because it uses too many processes and memory. i tried deleting some extensions, I tried using task manager to close separate processes but i always end closing the wrong one and closing firefox completely i tried going to dom.ipc.processCount and change the count to 1. I'm so confused, it's slowing down my games i play.

I tried to Connect Dropbox to my desktop, but the page would not load.

Chrome has no problem loading the page.

Could someone please let me know if they have the same problem

Every time I come across a file and click the link to either open or save the file, Firefox just downloads the file -- THEN it asks me if I want to open it or save it..? It's bugged and an obscene security threat if the browser is so easily willing to download files against my intention.

Before I'm asked, I have gone through the settings multiple times to ensure 'Always ask you where to save files' and 'Ask whether to open or save files" are checked. Behavior does not change according to settings.

Example 1. Click link for a PDF with the intention to open, read, and forget 2. Firefox automatically downloads the file to my download folder 3. Firefox prompts me if I want to save the file or open it

If I click 'open', the file stays in the saved location even though I don't want it to exist.

Good morning, I have strange issue. Websites on my Manjaro Linux (GNOME desktop enviroment, using Wayland and Xorg) are not displaying correctly. Sometimes there are white fonts on white background-color, sometimes black fonts on black background. Sometimes where the bg should be white, it is black. I have Firefox Sync between my firefox browser on Windows 11 and Manjaro. Every setting in both browsers are the same. I tried to follow the instructions, like removing history, cache, cookies, turning off hardware acceleration etc. I just have no idea what to do now.

So this crazy new update has broken my Firefox in these ways:

1. All my bookmarks on my bookmarks bar have been deleted. 2. I can't drag any new links to the bookmarks bar 3. Overflow menu for apps is empty and will only let me drag Firefox defaults to it such as settings. Dragging apps to it is impossible. It "is" possible to pin items by using the Chrome puzzle piece..

Firefox: 109.0 OS: Windows 10 Pro

Using troubleshooting mode has no effect.

I found a really unusual behavior.

If I close Firefox using the "x" at the top right of the window, the Windows default for close, it does not restore session no matter what I do. I can manually go to the settings, history, recently closed windows, and restore them from there, of course - but that is a definitive hassle.

Strangely, even if I open up a new tab less than 2 seconds before I hit the X to close, it will not restore the session but does indeed save the new tab to the previous.jsonlz4 file, and makes that available via going through the settings menu.

What is oddly more unusual is that if I close Firefox by way of ctrl-shift-q, it works fine (opening Firefox after ctrl-shift-q restores the session without any extra intervention required).

How do I make Firefox recognize closing via the bog-standard-since-windows-3.11-for-workgroups X in the top right of the window as properly closing/quitting?

I recently updated my system (OpenSuse15.4) which included a Firefox update to version 109.0.

I regularly use my mic for google voice, however even though I can select my microphone in Google voice, It never shows any input.

I tested my mic in other apps and it works fine. When I pull up my systems pulse audio volume control (pavucontrol), it does not show firefox in the recording tab like it used to when using Google Voice.

To test to see if it was a Google Voice error, I also tried testing my mic at https://mictests.com/, and zoom.com, but after selecting my desired input device, mictests.com was also unable to record anything, and again, pavucontrol did not show anything being recorded.

I have attached an image of pavucontrol that shows audacity recording audio. Normally, I would also see Firefox in this window when using the mic.

I have tried watching videos through chrome and other browsers by searching something via duck duck go and watching that video on duck duck go, and it works on other browser so it must be specific to firefox.

Whenever I try to watch a video, in the drop down bar firefox select to mute audio for some reason. I then select 'allow audio and video' and refresh the page but the video is still muted for some reason. This also happens when I try to use other video sites. This has only started to happen recently in the past two days (and yes I am updated to the latest version of firefox).

https://addons.mozilla.org/en-US/firefox/addon/lightorange-on-black/ there seems to be a problem with this theme, cant install, cant upload or anything it says its corrupted can someone help? please contact me under my email [email removed from public]

How do I get the Bookmarks to appear on the left side on this WINDOWS 10 PC? It appears on the left side of my WINDOWS 7 PC. I can't find a setting in the FIREFOX Settings list?

Thank you.

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.
