Firefox Support Forum

Locking this thread, please continue here: [/questions/1440721]
Can someone please tell me how to answer questions asked, in emails to me, receoved from support helpers. In ~6 emails received so far, my only response option looks like clicking the "Mark It as Solved" button...I can't see how to answer, for example, that I'm using Debian Buster, with KDE. Also, jonzn4SUSE asked me to "see screenshot" of his SUSE distribution, but I can't see that image, nor a file attachment. Thanks again.

Hi,

I'm developing web app. I created and set up ssl auth for localhost with self signed cert.

When I hit my endpoint with firefox I see:

Secure Connection Failed

An error occurred during a connection to localhost:8081. SSL peer cannot verify your certificate.

Error code: SSL_ERROR_BAD_CERT_ALERT

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

How to disable security in FF so I can test my endpoint?

I use synching between phone and desktop. I deleted some bookmarks on my phone and synced phone and desktop Firefox. I would expect that the deleted bookmarks also disappear on my desktop FF under "Mobile Bookmarks", but nothing changes. Worse than that, after I added one more bookmark on my phone and synced, the deleted bookmarks showed up again on my phone. It seems the not deleted bookmarks on desktop are transferred again to my phone. This is actually not what I want...

There is "show in folder" menu for file in downloads. And it will launch my file manager at the parent folder for the selected download file.

There are so many files in my downloads folder, so i would like the specific file to be autoselected. My file manager support this if i pass the filename as parameter in the commandline.

However, seems that firefox only pass the parent folder path to my file manager in the "show in folder". However can i customize firefox so that it will pass the full file name to my file manager when i click "show in folder", and my file manager will open the parent folder with the specific file autoselected.

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

On linux terminal the text should change color but how do I do that on firefox? By the way I have these settings for the caret ui.caretBlinkTime 0 ui.caretWidth 7 Not being able to see the character under the caret is problematic, would be nice if anyone knows what to do.

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?

Thank you in advance for your advice.

When I enter a search string for both yahoo or google (but not as yet duckduckgo) somewhere the string is "edited" before it is sent and all extended search characters deleted so "field1 field2" and "field1 -field2" return identical results. Some of the editing can be seen when the text is transferred from the search window to the address window. for example my try at ' "-"field2' was edited to '- field2' with a space between '-' and "field2". I am running Linux Mint and have done a Firefox update with no effect. Note that this not how it used to behave.

I accidentally logged my self out of my Mozilla browser and i don't have access to the email registered in this account cause i had decided not to pay for extra space the gmail account (tindijack@gmail.com), I opened a new email jtindi300@gmail.com is there away i could link the two to use a single account? I have my school passwords the mozilla account under that email, i still have access on my phone but i just don't have it on my laptop how can you guys help me?

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 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.

System details:

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Desktop environment: GNOME

I'm installing a Docker service set onto a new Ubuntu system, that has Firefox installed by default. One of the services is a GUI application.

However, when opening Firefox for the first time, a dialog shows up that I would like to disable (attached).

How can I disable this?

I'm running Firefox using: "/usr/bin/firefox --kiosk http://localhost"

I've already followed a lot of the suggestions in here: https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs (and verified they are indeed set after installing my own "user.js" file), but I cannot find an about:config preference that disables what I'm still seeing.

Any help or ideas?

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.
