Fóram Tacaíochta Firefox

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.

Extension has permission "Access your data for sites in the abc.de domain".

The documentation says that such extension can read "data you enter into those web pages, such as usernames and passwords"

Can extension send such data away (for example to its developer)? What kind of permission is needed for that? Can you quote exact name of such permission/s from linked article so i can lookup that?

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!

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.

I used to be able to show speed dial bookmarks on my home page, as many rows as I had spd dial bkmks, like 30 or so. Now I cant even get speed dial to show anywhere anyway. I really want it on my home page, so when I launch FF or open a new tab, it auto shows all my speed dial bkmks. Please restore this functionality. We should not need some special extension to do this. It should be an option off the Settings tab

This one really caught me by surprise! I have an internal Django database system. Staff typically use Firefox or Chrome to access it from Linux or Windows machines. As part of this system, it uses Grappelli library which in turn uses TinyMCE V3.5.8. Specifically, in a text box TinyMCE provides advanced editing and fonting. Allows the user to embed links or images. This system was working fine on Django 2.2. My provider (Python Anywhere) retired the server image I was running on, so I updated everything to Django 4.2 on their latest "haggis" system image. Everything seemed to transfer over without any errors - at first. In fact, it was a week later somebody tried to change a font colour by clicking the popup button that opens a colour picker. That pop up looks blank! (its not, the HTML is there but without the custom CSS nothing is visible)

In developer mode on Firefox or Chrome I can see what the problem is: The popup is disconnected from the parent. The parents CSS and classes - specifically tinyMCE - is not present. So its missing the styling and JS to operate. One of the first things the popup JS does is copy in the tinyMCE and tinymce classes from the parent. But they are not there, in fact .opener is null and .parent is stripped down.

What is really weird is on my test server, where I tested everything before updating the live server, it works! The test server uses Django's "runserver" to run a very simple (unsecure) http server just to test code. Whereas the live server is locked on HTTPS.

What confuses me is I don't see any console log messages that would indicate the browser decided to "protect" me. How can I figure out what is going on? Or disable this feature for a test?

I am writing this on my Dev machine using the browser I test with, so I shall try to paste in tech info below.

Just to reiterate, in this browser I can have my test server in one tab, my live server in another tab, test server popup works; live server popup does not.

Thanks in Advance, Richard

Dear Firefox Support Team,

I am experiencing an issue with Firefox where it unexpectedly closes without any warning or generating a crash dialogue. This issue occurs when switching between any tabs, not exclusively ones with active media content such as YouTube, as previously suspected. This problem has persisted across multiple instances, without a discernible pattern or specific tab content causing the issue.

• • Firefox Version:** 124.0.2
  • Operating System:** Ubuntu 23.10, Linux 6.5.0-27-generic
  • Extensions/Themes:** [Provide a list of enabled extensions, or note if the issue persists in Safe Mode]
  • Recent Changes:** [Mention any recent system or Firefox updates]
  • Graphics Card:** NVIDIA GeForce RTX 3070 Ti, Driver Version 535.161.07

• • Steps to Reproduce:**

1. Open Firefox with multiple tabs. 2. Switch between various tabs. 3. Observe that Firefox occasionally closes unexpectedly without any crash report dialogue.

• • Attempted Solutions:**

- Checked `about:crashes` with no submitted crash reports found. - Monitored for errors using the Browser Console but found nothing consistently leading to the issue. - Attempted running Firefox in Safe Mode to rule out extension-related issues. - Disabled hardware acceleration to see if it impacts the occurrence, with no change.

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?

Hey,

I'm looking for a shortcut/hotkey to focus the page.

The best I found is "Move to Next Frame", which is F6. When having the URL bar as focus, and no bookmark bar open, this will focus the page.

I have two questions here: - Is there a better way to focus the page? - If not, how can I remap F6 to a more usable hotkey?

I have found some threads with workaround like tabbing 2-3 times until the page is in focus. I'm looking for a single shortcut, having to press a key multiple times kinda defeats the purpose of a shortcut.

I have found information on how to remap hotkeys with either extensions or autoconfig, but I can't find which key I have to change. Extensions don't seem to include this key.

For autoconfig, I looked through view-source:chrome://browser/content/browser.xhtml and the Browser Toolbox to find this shortcut, but with no success. Maybe I looked at the wrong spot, maybe not all shortcuts are listed there?

Any help is greatly appreciated.

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.

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 noticed the mozilla.org website has a new favicon. I feel like that sort of thing usually alludes to some forthcoming development. Hmm...

My question is. Hmm? I wonder what's going on over at Mozilla.

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!

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?

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...

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?
