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?

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

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.

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.

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.

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...

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.

Im using Playwright with JS and when Im running ny test on FireFox i get a PopUp message to select the screen i want to screencast, even when im choosing screen and pressing "Share" its happened in the next test and not recording my tests. its happened only in FF. How im removed this PopUP ?Thanks. Using also Linux Ubuntu.

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!

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

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.

I have enabled privacy.resistFingerprinting in Firefox. I have also set my default zoom level to 133%

When I open a website (e.g. https://github.com/), it is zoomed to 133% as expected. If I then navigate to a page on that website (e.g. https://github.com/pricing) using the menu at the top of the page, then the new page is still zoomed to 133%. So far, so good.

However, on the new page (https://github.com/pricing) if I increase the zoom over 133%, then navigate back to the original page (https://github.com/) using the menu at the top of the page, then my zoom level is reset to 100%.

Is this expected behaviour? I would have thought that the zoom level would be reset to 133%, not 100%.

I found this, which seems somewhat related: https://bugzilla.mozilla.org/show_bug.cgi?id=1609880

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.

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'm using the current Firefox-ESR for Linux x86_64. Under Settings > Privacy and Security > Cookies and Site Data > Manage Exceptions, I blocked http:174.138.51.92 and https:174.138.51.92 several weeks ago. But Manage Data shows 10 cookies last used 45 minutes ago, and Remove Selection for these cookies fails (incidentally retaining the "last used" value), even when repeated multiple times as fast as I can mouse the select, then Remove Selection, then Save Changes then Manage Data .

How can I delete these cookies and site data? And why does it fail for this site and this site only? And how can I block them permanently, short of black-holing that site in /etc/hosts?

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.
