Firefox 技術支援討論區

Hi all, due to the occurring problem I cannot select topic to describe best my type of question:

Description of fault: Using Open Suse Leap current version 15.3 (KDE) with all patches installed (zypper dup: no action required) In either thunderbird and firefox application (but e.g. not in dolphin or k3b or gimp...) I have following problem: When pressing any entry in File ... View... bar I do not get a visible dropdown menu to chose from Firefox specific: When I try to use a bookmark folder in the bookmark bar there is no visible dropdown menu to chose from When I try to chose from a dropdown menu inside the content of a web site i will get no visible feedback at all.

BUT: when I want to chose a bookmark that should appear in a dropdown list and I move the mouse to that remembered position I see in the lower left corner the bookmark's address and I can chose it! The same happens with the dropdown menus from the the File.... View... Help line. I am able to chose a command once I remember where to point to.

So I guess all what is missing is the overlay plane where the menu contents reside.

This problem occurs in 95% of the time I use both applications, BUT there are 5% of the time where everything works like a charm. I have no idea what i do differently in that usage. Whenever Firefox works normal, also thunderbird does. Is it somehow a KDE releated problem?

How can I fix that problem? Any hints?

Thank you

Johannes

When I restart my computer, I am logged out of all websites although I did not select settings such as "Delete cookies and site data when Firefox is closed". This only happens with reboots and not on Suspend.

I saw two similar posts but the options look like they changed name since then: https://support.mozilla.org/en-US/questions/1319622 https://support.mozilla.org/en-US/questions/1289909

I tried to apply the solutions linked there, to no avail.

This behaviour only happens on my Garuda Linux and not on Pop-os. Thus I am not sure here is the right place to ask this question.

Another strange bug which may be related is the following: if I zoom in a page (say set it at 120 percents) then go to another tab and then come back to the page I zoomed in, the zoom is reset to 100 percents.

Any help would be greatly appreciated!

PSA:

The snap version of Firefox (as implemented in Ubuntu Desktop 22.04) will not open a Zoom meeting link.

The alternatives are: - Google Chrome, etc. - Borrow a Windows machine and log into your meeting there.

What a disaster.

how do I work with attachments in unbuntu? it greys out when trying to upload any attachments in gmail and outlook. I am new and cant find unbuntu help on latest update.

Hi,

I'm using Duckduckgo as my search engine, but when I type in a search string, it Firefox prepends it with https://html.duckduckgo.com/html/... This opens a search page that doesn't follow my dark theme. When I click on a link, another link is added that creates a link back to the same URL, causing a loop. This never happened before I upgraded to Ubuntu 22.04 & the latest version of Firefox, 100.0.2. How can I change this back?

Thanks!

Hi, Could someone tells me how to deactivate the startup popup upon each firefox start which says (translated) "thanks this is 100th version of firefox, start navigation", or is it to stay until the 1000th annniversary ? Thanks

I'm not able to get hardware accelerated video decode working on Firefox developer 101.0b7 on Arch linux X11 with VA-API. This is verified by a lack of Video activity in intel-gpu-top

There is also no obvious error message. On youtube videos I sometimes see

[2022-05-16T17:36:32Z ERROR mp4parse] Found 2 nul bytes in "\u{0}\u{0}" [2022-05-16T17:36:32Z ERROR mp4parse] Found 2 nul bytes in "\u{0}\u{0}" [2022-05-16T17:36:32Z ERROR mp4parse] Found 2 nul bytes in "\u{0}\u{0}" [2022-05-16T17:36:32Z ERROR mp4parse] Found 2 nul bytes in "\u{0}\u{0}"

but on Big Buck Bunny from https://test-videos.co.uk/vids/bigbuckbunny/mp4/h264/1080/Big_Buck_Bunny_1080_10s_1MB.mp4 I don't get that output and everything looks normal:

libva info: VA-API version 1.14.0 libva info: Trying to open /usr/lib/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_14 libva info: va_openDriver() returns 0

but the video decode in intel-gpu-top shows 0%.

VA-API is confirmed to be working in mpv, if I play that same big buck bunny video in mpv I see 10-20% video decode usage.

vainfo shows

As far as I know all flags are set properly (according to https://wiki.archlinux.org/title/firefox#Hardware_video_acceleration) and I have set MOZ_DISABLE_RDD_SANDBOX=1

Firefox supports Websockets, which allows servers to push arbitrary data to the client, instead of having to rely on polling methods via HTTP and JS. Whilst solving one problem, it creates another. I do not like the idea that any website can just ask Firefox to make a persistent WS connection without my consent. The same is true for service workers, but (unlike websockets) i'm not at all interested in using those. Luckily there's a configuration option to disable support for websockets, network.websocket.enabled, wich is exactly what i've done.

Is there a way to selectively allow websockets, based on IP or domain? If not, why isn't there one? Am i really the lone outsider who's concerned about security?

I want "Firefox Suggest" suggestions to operate like normal in regular windows, but not show up in private windows.

Is this possible with an "about:config" tweak?

Hello! When i installed Ubuntu22.04LTS on my PC. I found i can't input any chinese in this brower!!!

I think is firefox use snap's wrong! Please fix it.

Ubuntu 22.04 LTS 64bit GNOME 42.1 X11 IBus 1.5.26

Starting around v98.x, every attempt to download a file (eg with "Save Link as") immediately result in a Failed message in the download list.

This happens despite the setting "Always ask where to save files", though it doesn't matter. The Failed message appears before I am asked where the file should be saved.

Downloads work if I log in as another user.

If I restart firefox with "-safe-mode", I can do downloads. But not if I then start in regular mode.

The problem started in late March or early April 2022.

Extensions: Facebook Container, GNOME Shell integration, Hide Private Mode, IP Address and Domain Information, NoScript, TreeStyle Tab, uBlock Origin

I have the Download setting set to "Always ask you where to save files" and PDF handling set to to "Open in Firefox" if I now click on the download button in the opened PDF it automatically saves to the Download folder without asking, which is never what I want. If I set PDF handling to always ask, and open in Firefox from the dialog and press on the save button then I get asked where to save. This seems like a bug to me, as it is very surprising behaviour. Is there some way to always open the PDF in firefox but get asked where to save the pdf when pressing the download button in the PDF viewer?

See above on Subject = inability on my laptop with Firefox provider to watch certain dramas/films on 4 due to DRM. My problem is trying to follow the instructions hitherto given. I just want to be able to access those sites with DRM overlordship getting in the way. I am an old man who is simple-minded, that is, not 18 years and adept at whizzing around laptops.

Recently I have noticed that when I want to display HTML source of the page Firefox asks me to log to the site once again. WHY? I am already logged in. The page is already loaded and displayed. So why it needs my password again?????

In some cases the page is actually loaded once again which can result in different content being displayed as "a page" and different as "a source" (if there is a dynamic insertion on the page changed on every get). But sometimes it shows old, cached source while the rendered page is already changed. I know that I can see actual content by using the Inspector but "show the source" function was more convenient. Now I can not believe that the "source" shown is a source of the actual "page" Such misfeatures make the function totally useless.

Firefox version 91.8.0esr for Debian.

Why I can't I see this? or where can I find it?

Various Fire Fox sources say I need to set up an Firefox Syn account and that I can make a selection to do this in Firefox preferences. However this is no option for this available. There is a single option labeled sync but it doe does not synchronize my laptop to my account and none of my bookmarks etc are up to date.

FF uses all memory. I start computer. Start FF to blank page. No Internet connection. No other programs running. Ran memtest before - all Crucial RAM good. If I leave FF on, doing nothing all RAM will be used. Linuxmint 20.3, FF 100. Does this happen with Windows or Mac?
