Firefox 技術支援討論區

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

Hi - Javzscript Enable, though "True", still brings up the error "Enable Javascript". I spent hours on this, but nothing useful was found. Has any one had this problem, and if so, were they able to fix it?

Best regards, Nick.

Since the Firefox update released 2 days ago (version 115.0.1) I'm constantly having an issue which causes the video to stop playing after the adverts. I eventually get a video unavailable message. I've cleared my cache but it's made no difference. I'm hoping that this is a known issue & that someone is investigating ?

Dear Madams/Sirs, why does firefox using a download limit. Each transfer stops (without a message) after downloading 1GB. I couldn't find any configuration-points where it is possible to change the download limit. With using Microsoft Edge I got full downloads greater 1GB. Many thanks in advance.

When I'm trying to go to a specific website, it doesn't connect with an error code "SEC_ERROR_UNKNOWN_ISSUER". I was able to press a button labeled "Accept the Risk and Continue" before, but the button seems to have disappeared?

How do I have all my bookmarks and folders sorted by name automatically and permanently? When I open Bookmarks I want to see the folders sorted and the bookmarks inside each folder sorted, automatically so I never have to manually. In other words, behave like Windows File Explorer.

I'm almost certain I had it working that way on a previous installation of FireFox, but I can't get this new installation of Firefox to do the same.

I have multiple monitors and most often have Firefox windows open on each. Lately, I've been noticing that the Desktop Window Manager process is consuming a huge amount of RAM. At the same time, consumption completely disappears with the closing of Firefox windows. Video: https://i.imgur.com/pHCa7Hh.mp4 (I left it for a while then closed Firefox windows) After a while, I noticed that already 13 GB of memory is being used by DWM. I don't know if sites affect behavior, but most often I have https://music.yandex.ru/home open

When using firefox to access my gmail, if I open a page in gmail I am unable to close that page (nothing on that page works freezes). I am unable to transfer that file to my favourites. The only way to close the page is to close the tab, this is not my preferred way of using gmail. Any help would be greatly appreciated Regards Mick

I have 8 windows open all the time on my main Firefox, and switching between them is hard because the name is that of the last tab I used, which might not be very human-readable or might be similar to one on another window. It would be great if I could name my windows! Is there a way to do that? If not, could I request that as a future feature?

Hello, While not on every occurrence of starting Firefox, too many times Firefox won't bring up its home page (Google) because two applications running in the background (Memeo Premium Backup and Trusteer Rapport) start to run at the same time and contribute at least 70% of the CPU load, with Firefox accounts for another 20%.

I imagined that Google is flooding Firefox with a lot of files that Memeo begins tabulating for transfer in anticipation of its external backup drive being eventually switched on.

So I decided to tell Memeo to specifically exclude two system folders which might be storing temporary files when Firefox is active.

C:\Users\**\AppData\Roaming\Mozilla\Firefox C:\Users\**\AppData\Local\Mozilla\Firefox

Doing this did not improve things, as Memeo and Trusteer occasionally turn on as Firefox is starting up.

Does anyone know of any other folders which could be potential locations for temporary data that Memeo may feel obligated to interact with.

Thanks

I'm trying to stream my NPR radio station -- https://www.kunm.org/ -- but cannot hear any sound. However, I can hear a tv livestream -- msnbc.com.

I can listen to kunm.org on Chrome and Edge.

How can I listen to my radio station on Firefox?

I am trying to view a website that is protected by cloudflare and afew days ago I could look at it with out issue now it keeps coming up with Checking if the site connection is secure XXXXXXXX.net needs to review the security of your connection before proceeding.

I removed the web sites address from the above as its does this with a few sites

I have tried to view the sites in both Private/incognito Mode and standard window

if some one can help me figure this out I will be most welcome as it means I can view some of the sites I normally see there is a button that says to verify you are human but when I try to click it, it dissapears and starts constantly reloading or just a moment showing

yes I have a VPN and have tried viewing sites with and without it on as well as using a different browser

There's surely no option for it now, but I would like to suggest adding a setting for each user that can affect all or individual add-on extensions : force silent updates. You see, when add-ons get updated, they open a new tab. Now this can be useful or simply interesting, but sometimes it's just obtrusive for people, especially when watching a video. This happened to me a couple of times, I'd be watching a YouTube video on full screen and suddenly the program would exit full screen and switch to a new tab where the add-on page is open, and the video is still playing. Thanks!

When a new bookmark is created, it isn't saved in the specified location (which I will henceforth call the "folder").

For example: I'm on a page I want to bookmark, so I select Bookmarks>Bookmark Current Tab. In the Location it already has the folder I want, for example, "Math". I click Save.

Naturally, I expect the bookmark to be saved in the Math folder. But it's not. Instead, it will be in the "Bookmarks Menu" folder (which is the outer folder that contains Math). If I select Bookmarks>Edit This Bookmark, the location will show "Bookmark Menus", not "Math". If I try to use the bookmark, it's in Bookmark Menus. If I then change it to Math, the bookmark will now be saved in the correct folder.

The same thing happens if I select "Choose" when originally creating the bookmark, and then select the folder. The bookmark will be created in Bookmarks Menu.

I've learned to always (or almost always) remember to edit each bookmark after creating it, but it's still a very annoying bug. It's been like that for as long as I can recall, and is still the way in 115.0.1.

I have a Microsoft outlook.com email address that I use for my FF account. My authenticator email was setup in Authy without problem however FF does not accept its 2FA 6 digit code which makes me think the app may not be compatible with FF. My cell and laptop are setup to auto recognize location for time setting.

Comments please...
