Firefox 技術支援討論區

When I start to type a reply to a Facebook post, the page scrolls down so that the line I am typing disappears one line below the bottom of the screen. I have to scroll down to see what I'm typing. Also, it jumps down the same way whenever I hit the backspace key to edit what I'm typing.

I discovered a previous (archived) post on this forum that suggested using "about.config" and making sure that the value setting for browser.backspace_action is equal to 2. But that didn't change the annoying behavior. Is there any other value I should try? It's not clear what the number means.

Nor did setting browser.backspace to true (or to false) seem to help with the unwanted jumping upon use of the backspace key.

This only seems to happen with Facebook, but it's quite annoying.

OneDrive links recently stopped opening (browser tab shows the OneDrive icon but the page shows no content); Edge continues to open the links. I am running Firefox 99.0.1 (64 bit desktop).

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

I cannot play CNN videos in Firefox. They will not start. I can play them in Microsoft Edge and on my iPhone. I can play other videos in Firefox from, say, YouTube. It's just CNN that seems to be the problem. I have a Windows 10 PC.

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

When playing videos on youtube or any other platform the volume is very low to non-existent. When a new video starts there is a sudden surge, whereafter it rapidly returns to a non-audible level. I have tried checking the volume settings in Windows and Firefox but nothing has helped thusfar. Please help me resolve this issue so I can go back to using my favourite browser again.

Thank you in advance!

Hello, I have a strange issue. When I am in Gmail using Firefox, my time is off by 5 hours. I can open Gmail in Edge and the time is correct.

I have 2 time zones listed in my Google calendar. I removed the secondary one and the time still stays the same.

One posted mentioned that they changed the computer time zone and this resolved the issue. I tried that and still get the same incorrect time.

I can log into my laptop and I get the same issue with Firefox being 5 hours off but Edge being right on time.

Any input would be greatly appreciated. Thanks Mike

Subtitles in picture-in-picture are doubled. I've tried clearing the cache and restarting the browser but the problem persists. Site in question is Netflix (first image). Does not happen on YouTube (second image).

Since about 2 weeks ago many AOL attachments are not opening (pdf.s are but others eg Word not). I have read thru' previous messages on this (in 2021) but turning off enhanced tracking has not fixed it. My attachments open in Edge and Chrome. Like others I would like to stay with Firefox but cannot live with this problem. Help please

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

Hello,

I am learning to look at websites with help of the development tools and the inspector tab and I am trying to get into how the web works and how the different programming languages interact and so forth. When moving the mouse over parts of the website, the relating code is highlighted in the inspector tab. I am having an issue as follows:

The first image shows a part of the website code. The mouse cursor is on no specific position, I marked its position with a blue arrow.

In the second image the mouse is over the red "free options" button and in the inspector tab a div appears out of nowhere. It does not appear in the code unless the mouse is moved over the button and disappears as soon as the mouse leaves the button. I have never seen that before (maybe because I am a beginner) and have no clue what happens there.

Is that done with javascript? Or with php? Or with css? Or anything else? What happens there and how can the actual code change?

In the inventor tab, does the code have to do with the DOM rather then the sourcecode of the website is that right?

Please give me some light =)

regards p3ppi

In KDE 5.24.4, Linux. I started to have some issues with "Open containing folder" probably because I installed many Gnome apps which may cause bad configurations in my system.

I suspect this cause this issue even though I don't really have gnome file manager:

https://polywogsys.livejournal.com/309405.html "Gnome based file managers, Nemo/Caja/Nautilus provide the entry org.freedesktop.FileManager1. So it doesn't matter what you set as your default application for the filemanager mimetype - as per the freedesktop.org standard, firefox will always select a filemanager based on dbus (if it's there)"

But because the mimetype points to "dolphin", I dont really have other explanation either: $ xdg-mime query default inode/directory org.kde.dolphin.desktop

Just recently I am having trouble viewing videos of any kind, in Facebook, or u tube videos, Firefox has worked perfectly until a couple of days ago, I don't know what has changed

Normally there is no difficulty searching a pdf with a pdf reader. How does one do it in Firefox?

Note that ctrl+shift+f and ctrl+f do not work.

Website changes when developing never show the change even with cashing is operative. Regular history cleaned ETC ETC - Means CACHE CLEARING NEVER WORKS. This is a VERY BAD PROBLEM that is quite common. How these idiots at Mozilla have never fixed it indicates they useless. I've been recommended NEVER to use firefox because of this issue. So its back to Chrome and I hate supporting Google.

Hi folks, I've been searching but haven't found anything, the Twitter Twists aren't showing on my home page. They are displayed on all other browsers such as Chrome or Opera, here is the link. https://borderline-selbsthilfe.org Thank you Greetings Alaska
