Firefox 技術支援討論區

Hello,

Since about 3 weeks, Firefox hang on certain websites while trying to load them, when un-ticking all "Firefox Home Content" items. When those things are ticked, everything is fine. Wasn't happening before. Often a gray geared wheel appear and at other times only the "tab text" appear, please see the attached screen shot. I'm able to click on "File Edit View...", the items present on the bookmark toolbar, "Refresh", "Home" but the action is executed only when Firefox un-hang. I'd already get a look at Firefox help tutorials but there was nothing about "The "Firefox Home Content" can cause Firefox to hang".

It take me about 10 minutes to load this current page. "Firefox Home Content" are not ticked right now.

Thanks,

Guillaume

Hi All

some pages like this one are wide enough to have a horizontal left/right scroll bar.

https://trello.com/b/3OtE8BCR/brizy-wordpress-public-roadmap

If I'm lucky, when I want scroll left or right, the cursor is on a piece of HTML where it can move when I use the left or right arrow keys. However often, the cursor isn't available or the right place.

Is there a key or key combo where I can shift the web page left or right in the FF window? I often find it difficult to use the horizontal scrollbar with the mouse.

hi all, i try to import all passwords from vivaldi to firefox 78.0.2 but looks like there is completely no option to do that. the only export option is when i open import wizard which tells me "no programs that contain bookmarks...could be found" which is complete nonsense as i have a vivaldi running and full of passwords. please do not advise me to put manually every password,i have close to 100,coze this will not happened. btw,im on latest manjaro xfce,just fyi if its important. thx for help in advance.

I'm having a hard time getting the settings right for what used to be default link behavior. I want links in web pages to open in the same tab, unless the page wants something else. I want external links, i.e., from Thunderbird, to open new tabs if Firefox is already open. Can anyone tell me how to fine tune the settings to get this behavior?

I have been using Firefox ESR 52.9.0 (32bit) on my Windows XP computer for some time now and a while back there was a problem with security certificates. They issued a special patch for the ESR version so we could continue to use Firefox. It would appear that this problem has somehow reappeared. Can we please get a patch once again to clear up this issue.

Thanks

I can't send troubleshooting information because I can't even connect to the Mozzilla website on my XP computer. I had to send this request from a different computer

Is there any way to toggle protection settings for the optimizely somehow? I would like to prevent request blocking. The same problem occurs at least on one other PC with Linux, haven't checked on Win or Mac.

Not sure what the right place for this is; I wasn't able to find a Firefox support forum specifically for web developers. If anybody knows of a more appropriate forum, please let me know.

I'm trying to intercept the opening of a popup window from JavaScript, but I can't find any way to trigger the debugger on this condition, and I don't want to set the breakpoint manually because the source I'm working with is obfuscated and it would take a lot of work to track it down manually. I currently have Firefox 68 ESR, but I could upgrade if needed. Does any version of Firefox have a way to set a breakpoint on new tabs/windows opened from JavaScript, or is there a way to break on the `window.open` function which I suppose is what is being used?

Hi everyone.

At first there was no synch between windows and linux. After consulting existing help articles I set a master password on both OS. This has lead to the linux information being successfully synched to the windows system but not vice versa.

Sorry that I' not tech savvy enough to have listed any more information here. I'm using ubuntu and windows 8.

To be honest I don't use windows anymore but need the saved login details on ubuntu.

Thanks!

Well, I used to use the mozilla repo, encountered the issue, switched to the openSUSE repo (slightly older builds) where all worked and now the issue is back...

After updating all packages, Firefox no longer launches and instead I get the little Window shown in the attached screenshot.

I have zero idea why and how - though it does seem like someone didn't do their testing properly...

According to YaST2 this is Firefox 78.0.2-1.1-x86_64

The installed packages for Firefox are (all from "vendor OpenSUSE") MozillaFirefox MozillaFirefox-branding-upstream MozillaFirefox-translations-common

There is also the kmozillahelper for the Plasma Desktop. - zypper ref and zypper dup confirm that the system is up to date.

Firefox will periodically broken at any time of day, in the middle of a work emergency, because it performed an update in the background. I am *not* looking to disable updates, which is all I can find information on. I still want the ability to install them when they're available or when I start or exit firefox, or whenever it might be. But I need to be able to have control the "feature" of Firefox just randomly and unpredictably crashing during the workday. How do I disable or workaround this feature?

I use openbox as my windowmanager with NO desktop environment on Archlinux.

I want to hide the titlebar (border) but when using openbox this option is NOT SHOWN. It is shown when i use another Desktop Environment like xfce4 or Gnome.

In the past i found out that a variable like DESKTOP_ENVIRONMENT, DE or XDG_SESSION_DESKTOP could be set with the value of another Desktop Environment to mislead Firefox.

However, i can't find the right variable any more and i have been googling and googling for days :-(

Please help, i like openbox & firefox (without titlebar)

Hi there!

I have been having trouble with Firefox continuing to autoplay videos even with preferences set to "Block Audio and Video."

If I go to twitter.com or elsewhere Firefox will show that auto play is disabled, but videos will autoplay with no audio. I would just like to get this feature working as autoplaying videos are incredibly annoying!

Thanks for any help!

Firefox 72.0.1

So, in a nutshell:

• as of a few weeks ago, I can read, but not edit Confluence pages from Firefox on one laptop (the page content does not load for editing, it gets stuck "Connecting...")
• starting the browser in "safe mode" does not help
• editing from a private tab for some reason works (!?)
• it works perfectly on another laptop (both Ubuntu 18.04, latest Firefox)

I'm hesitant to try "refresh browser" because I'd lose quite a bit of historic data.

Any suggestions on how to get to the bottom of this?

Currently I'm working on a tool to manipulate metadata in Firefox's cache2 cache-files. Since I did not find a source on the file format used that is either up-to-date or complete I worked my way through the source code for an "official" documentation of the format.

My program is able to read the metadata successfully but when changing some data Firefox does accept the file anymore. It seems like I'm missing something but so far I'm not seeing it in the code.

So my question is, is there some sort of documentation available besides the source code or is it possible to ask a developer, if there is somewhere something where the integrity of the file is checked?

Thank you in advance for an answer.

I'm running Firefox 78.0.2 on a desktop system with Linux Mint 19.3 OS. I'm using Blackboard (online training hosting service) and, at one point, I clicked on a link "Share screen". The window in the attached image popped up. However, I decided I didn't want to actually share my screen. I found absolutely NO way to get rid of this pop-up UNLESS I actually selected "Allow" or "Don't Allow". I tried clicking somewhere else on the screen, clicking outside of Firefox to take the focus off of it, opening another program altogether, clicking on the various icons next to the address bar. Nothing worked. The only work-around I found was to select "Don't Allow", then manually click on the new icon, and "X" next to "Block screen sharing". Is this a bug? Or can I put in a feature request to put a "X" (close window) on this so that I can make it go away without having to jump through those hoops? Thanks.

I spend 12+ hours a day in front of a computer and blank pages hurt my eyes. I use dark mode wherever possible.

I've changed the background color of about:blank already and it works as I expected.

However, when a request is fired to load a web page, there's a quick transition which may paint the canvas totally blank before starting rendering the requested page. Since this transition may take a couple of seconds sometimes in my environment, the screen flashes blank onto my face, really hurting my eyes used to most of things dark most of the time.

Is there a way to configure the color of this transitioning blank page, please?

Thanks a lot in advance. :-)

If there is a "(" in an url when trying open a tab in cli (-new-tab) I get the answer: bash: syntax error near unexpected token `('

Example: try 'firefox -new-tab https://en.wikipedia.org/wiki/Bernicia_(disambiguation)'

Any idea?

I cannot access Mozilla via Firefox - issue arose when trying to access add-ons yesterday (25 Jan 2020). Firefox displays the following: "Secure Connection Failed

An error occurred during a connection to addons.mozilla.org. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem."

In order to post this, I have had to access the site via Chromium, which also noted a secure connection error. I have used a VPN add-on to secure the connection and access the site.

I assume this is an issue on the Mozilla server with an expired certificate?
