Firefox 技術支援討論區

Hello, I've already contacted you because of a problem that I encounter with the functioning of my browser that cracked without explanation. The problem was that I was working on inpravate navigation and I can't find back the internet pages that I was watching. I don't know if there is a possibility to reach them back and I'm afraid I'll can't get them if I turn my computer of.

I need a quick answer because I'm afraid that my computer could crash because it's lit since a while.

Thank you for your answer.

Hello,

Sorry to contact you again but my problem is still not solved and it's urgent.

I still doesn't have turned my computer off in case that you could help me find my pages back. I have no one else to help me with this problem and I deeply need the websites I was surfing on. I'm not sure I can find them by myself and I don't have much time for that.

Thank you for helping me and answering my request.

Hello Team.

I have an old Firefox Mozilla account, but I can't recall the primary email associated with it. However, I do know that my current email is listed as a secondary email on that account. I would like to unlink my current email from that account. What steps should I take to do so? Thank you

Hello there,

I like Firefox to ask me what to do each time with PDF documents, so I've set the action for PDF to "Always Ask". However, I've noticed that when I load a page with a PDF document embedded inline, and I select "Open with Firefox" on the dialog box, the document always opens in a new tab.

In other words: there are certain PDF documents that get displayed inline when the action for PDF is "Open in Firefox"; but those same documents get opened in new tabs when set to "Always Ask".

Is possible for Firefox to display PDFs inline while asking me what to do each time?

Thanks in advance!

If I try to goto a new tab the new tab just blinks and never connects. Say I am in ebay and I see something and click on it. A new tab is made but it just clicks and nothing else.

When activating reading mode with a PDF file, the content of the file is not reproduced in the reading mode window. To see the full content, you must go to the end of the PDF file in normal mode before activating reading mode, see this implementation video : http://share.emmabuntus.org/Accessibility/Problem_size_document_pdf_firefox_narrate.mp4

Do you think this comes from our PDF file which was generated from LibreOffice with the standard options?

Here is the link to this file: http://share.emmabuntus.org/Accessibility/Emmabuntus_Debian_Edition_5_accessibility_shortcuts.pdf

Thank you in advance for your advice.

I want my websites content to be remove in reader mode in firefox how i can acheive this.

I am a developer and i am using one div in which i have content and images in that i dont want to fetch them in reader mode.

Previously I've been able to select search suggestions using the keyboard when typing into a search bar. As of a few days ago this no longer works on some sites like YouTube, but does work on others like Google. The issue is not to do with num lock or scroll lock, and my browser is up to date (124.0.1 Ubuntu Snap version).

Recently upgraded to a new laptop, Thinkpad X1 Carbon 11th gen. Running a Wayland-based WM. OpenGL is working fine everywhere except Firefox. Works fine in Chrome, Blender, glxgears, Steam games. Firefox 121 gives the following error:

SHORT STORY:

I have been able to find extension behind errors shown in dev. console (F12 key) like CSP ones (mouse hover over the link near the error on dev. console (F12 key), Console tab, to see moz-extension://somestring and find first characters of the string at page about:debugging#/runtime/this-firefox) But is there any better/easier way to find out web page issue causing extension?

LONG STORY:

Website fails to load (but in a Private window loads OK). F12 key in normal window, Console tab, shows:

SyntaxError: redeclaration of let settings

clicking it, it further show:

abc123-def456-...-...-....:1:1

   <anonymous> blob:moz-extension://8834...

inject resource://gre/modules/ExtensionContent.sys.mjs:581

   AsyncFunctionNext self-hosted:852

when i search for mentioned 8834 (first letters of a long string) at about:debugging#/runtime/this-firefox (i get there clicking settings wheel at about:addons and "Debug addons".) then i find Chameleon extension.

So I try to pause extension in its menu, that not helped, but disabling whole extension in about:addons removed errors, yet page still does not load. 4 remaining CSP errors like:

Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). contentScript.js:160:48951 ...

when I mouse hover over the hyperlink "contentScript.js:160:48951" the browser status bar shows extension address and when i memorize first letters of the address and search it at mentioned about:debugging#/runtime/this-firefox tab, i find: Phantom (cryptocurrency wallet) Metamask (cryptocurrency wallet) Phantom (cryptocurrency wallet) Violentmonkey (provides userscripts support for browsers - I am using it only for https://github.com/Owyn/HandyImage which is disabled currently)

I have tried to didable all these extensions causing removal of a CSP errors, yet page still does not load in normal browsing window (in private does). Normal browsing window shows only one warning/error:

Source map error: Error: NetworkError when attempting to fetch resource. https://firefox-source-docs.mozilla.org/devtools-user/debugger/source_map_errors/ Resource URL: moz-extension://extension address here/browser-polyfill.min.js Source Map URL: browser-polyfill.min.js.map

when i search for the extension address first letters at mentioned page about:debugging#/runtime/this-firefox i find "Textarea Cache", disabling it does not make page load.

After re-enabling disabled extensions and restarting Firefox, page started loading. I suspect (likely wrong) that the python application which is serving local web page in question had exhausted connection limit for the normal browser window/process, but the private browser window process was OK.

What i can do better to discover the causing extension or other cause of failed loading page?

I'm looking for a simple extension. A one-click extension that would enable me to delete cookies at any time during a firefox browser session. I would like to exclude some cookies from deletion, so I'd like a whitelist option.

Has anyone come across an extension like this?

thanks for your consideration

I am trying to install Adobe Flash player in Firefox 84.0 (the last version support Flash player) when running in a docker container (Ubuntu 22.04.3 LTS). I had tried to run Firefox in my real machine (Linux 6.1.0-17-amd64 Debian 12) and it worked well. I just copy the file "libflashplayer.so" to the path "~/.mozilla/plugins". But when Firefox is running in a container, I do the same but it can't found Flash player plugin. No matter where I place the libflashplayer.so, like "~/.mozilla/plugins" or "/usr/lib/firefox/firefox", it don't work, I can't find Flash player in "about:plugins" or "about:addons". I start Firefox from a terminal and there is no error log. I have no idea why it can detect flash player plugin while running in a real system but don't work when running in a container. Thanks.

Hello forum participants,

since some Firefox versions the setting "browser.fixup.alternate.suffix" no longer works. I found that all "browser.fixup.alternate" entries do not work anymore. After searching the web I found an answer that the fixup.alternate options don't work when the protocol is https. So, because today nearly all Websites use https, this options are completely without function. In my case I want to add the default TLD ".de" if I do not enter the TLD. Is there any place (except source code, of course) to configure this behavior for https, too?

Many thanks in advance! Have a nice day

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Firefox correctly redraws the addon window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
5. Reopen the addon window
6. Switch system theme globally again
7. Observe that Firefox does not correctly redraw the addon window
8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
9. Reopen the addon window
10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

When you switch the language in a text field, the focus on that text field is lost and the focus goes to another browser tab. This only happens if at this time a video is playing in mozilla in picture in picture mode with the Always on top option enabled. How to fix it? (Ubuntu 22.04)

Hello, I'm using a document management system (SeedDMS for those who know) through Firefox 122.0.1 (64-bit, canonical 1.0, downloaded from packages.ubuntu.com for focal, running on Debian Bookworm, kernel 6.1.0-17-amd64/Debian 6.1.69-1 x86_64, X.Org X Server 1.21.1.7, KDE Plasma 5.27.5, KDE Framework 5.103.0, QT 5.15.8, i7-5820K, GeForce GTX 1070).

Within this document management system pdf.js (v4.0.379) is being used to preview/view PDF Documents. After starting Firefox the PDF view inside the DMS works fine until I suspend (to memory) and resume my machine. Regular HTML-content looks fine but the resumed DMS session shows only blank (all white) Pages inside the PDF view. Changing to a different PDF file doesn't help. The number and size of these pages is presented correctly. I can even select and copy (invisible) text from these blank PDF pages. The problem applies to all PDFs, whether they're single or multi paged, have images inside them (like with PDFs from a scanner) or not, etc. Reloading the page/closing reopening the affected browser window doesn't help, i.e. the problem persists.

I recently found out, that this also applies to PDF files directly opened inside Firefox (which also seems to use pdf.js as a PDF viewer), that is, this is not related to a specific site like my DMS.

The problem always persists until I kill Firefox and start it over.

Pdf.js seems to use a canvas inside a div (see screenshots attached) to draw the visual PDF content and another div to make the text layer selectable/searchable etc. I don't know what's happening to canvases on a system suspend/resume cycle in Firefox on Linux, but I suspect that's where the problem originates from.

This problem already affected older versions of Firefox and pdf.js.

Please let me know, if you need further information from my side to investigate that issue.

Thanks a lot!

Hi,

During of build process we have an error related to auto deduction before 'auto' in dom/bindings/TypedArray.h

For example the call ProcessTypedArrays() at line 128 in file ChromeUtils.cpp give the error.

Hello,

Like I suppose any user of older systems (Macs...) that cannot be updated to a newer OS version and thus locked-in to an older Firefox browser I received an email today:

"Don’t stop the sync. Upgrade your Firefox before March 31st."

Why, why, why??

Why would Mozilla take away this last little bit of usefulness after already having abandoned all updates to the browser itself? Why actively "fix" something that ain't broke in a why that does actually break it?

And don't give me the sacrosanctuous security argument please ;) - I never synced sensitive information, not even my browsing history. If security *is* the reason it should be hardly more difficult to disable/disallow just the syncing of that information at the server end. We're clearly speaking at a change on that end anyway, otherwise everyone NOT running the very latest version would be urged to update, not just users of v78 and older.

Anyway, I'm sadly aware of the fact this little rant or even a concerted action isn't likely to change anything, so what options are there? Any suggestions for browser extensions that provide syncing of bookmarks and maybe open tabs or even browser preferences?

Thanks!

PS: I'm posting this from another older system currently still running a Ubuntu 14.04 version that is in fact hardly younger than my Mac's OS but still enjoys Firefox updates...
