Diễn đàn hỗ trợ Firefox

I'm at a loss for words here. I have a website I frequent and it has a really annoying behavior. I'm a developer so finally I mustered the strength to do something about it. I googled how to create an extension in Firefox and within 5 minutes I had a working extension that solved their annoyance. However, I can only load it temporarily. If I close Firefox, it goes away. When I try to actually install it, it says I need to have it signed. I have now spent the better part of an hour trying to find out how to self sign it. I refuse to believe that I have to submit this to Mozilla for me to be able to install my own code. Can someone please send me in the direction of how i self sign and install my own extension. I have no intention of publishing, I only want to run this for myself.

Since about 13:00 GMT yesterday, Firefox could not load or display the Hostinger h-panel. It sometimes partially and sometimes completely displays all the page content. But all the controls are dead. Firefox seems to be very busy doing something. I told Hostinger and they spent some time looking into the problem. They got Firefox to load the h-panel but said that it was vastly slower than other browsers in doing so. With me, Firefox still stops doing anything once the content is loaded and ALL controls on the page are still dead. When closing Firefox in this state, there is considerable delay before the window actually closes.

I thought that perhaps Hostinger had done an update that called in some proprietary JavaScript extensions that Firefox couldn't handle. I get the impression that in trying to display the h-panel pages, Firefox is trying to acquire some content from an external site, as requested somewhere within the HTML/JavaScript source code.

Any ideas? robert_john.morton@yahoo.com

Hi Just updated Linux Mint from 20.3 to vs 21. Firefox Help now shows FF version Mint - 001-1.0 121.0.1

Also shows that FF updates disabled by Administrator.

Is this the latest version for LM 21 ? And how do I enable updates automatically?

Thanks

On this webpage on the link below, when the 'Comments' button is clicked, nothing happens. It works via the Chrome browser.

Firefox won't start after updating to version 123.0 on Ubuntu OS.

At the same time, no errors will appear, and there is also no specific crash report that would help understand the reason.

How to restore the previous version without losing profile data?

If i am on amazon for example and an item has more than 1 option, Honey presents drop down selection box so you can choose which one to drop list The issue is the drop down box never opens when you click on it, doesn't matter where on it you click, it wont open. I have cleared cache, reinstalled honey and nothing helps. I have multiple desktop pc's all running tumbleweed and they all have this issue. If i load Chromium that works ok, but i use Firefox and not Chromium. I'm using openSuse Tumbleweed (latest update).

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

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

I get the message under Settings: "Your browser is being managed by your organization". Clicking on that message shows that the policy DisableAppUpdate is true. Methods for remeding this situation do not work. Please advise on how to change the policy to allow update please

Got sick and tired of having to enter payment card info every time, so I decided to RTFM and follow instructions. I worked my way thru all the instructions on found on the forum pages, and was entering the information via about:config, and got to the popup where I was asked to confirm, and clicked the button, then clicked it harder, but nothing happened.

My guess is that my Firefox and/or my Leap15.3 installation has left some file permission read-only and Firefox is unable to save this bit of data, but I really don't want to run Firefox as root. I can say more, but I see there are more boxes to fill.

So, I included a screenshot of what I hope will be the useful part of my config file.

I had a number of tabs open today (~40). Because Firefox started to malfunction, I had to restart Firefox. It happened to me before and I knew that I can restore my previous session so I safely closed the tabs.

When I restarted it, I opened a tab and then I tried to open the Application Menu, but accidentally closed the window. Now, when I've re-opened Firefox and attempted to restore the previous session only that last tab appeared.

Is it possible to recover the pre-previous session? I use Ubuntu 18.04. Where is this information located? and how can I retrieve it?

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

Hello,

Starting Firefox 97, opening a file involves downloading it the same way as if I choose to save it. It results in both Download folder and downloads list in the browser being polluted with a million of files I only wanted to open once with a specific app (pdfs, xls, m3u etc.).

Previously Firefox was using a hidden internal folder for saving such files and deleting them later, so Open In App really meant "open, do not save locally". Now any option just means "Save the file to the Download folder and let it be there forever".

How can I fix this unsuccessful UX decision apart from downgrading to an older version?

Thank you.

P.S. "If you dislike new features in the latest version of Firefox, your first reaction might be to go back to the previous version. Rather than downgrading, try getting used to the new features..." is probably the worst suggestion you can possibly give to someone with their workflow broken by a sudden update they can't decline with a feature they never asked for.

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

Hi, how do we set Firefox 97 to use the os/system print dialog?

Before Firefox 97 we could change these settings in about:config:

print.tab_modal.enabled = false widget.use-xdg-desktop-portal = true

But they are both gone now.

There is now widget.use-xdg-desktop-portal.print, which is an integer (2 by default).

But no matter what integer it is set to, we still don't get the os/system print dialog.

We are using Arch Linux, but we don't expect that to be of any importance -- after all, it worked before Firefox 97.

Thanks for your time :o)

Using firefox in linux mint 19.3 mate. Until firefox 97, I could control the size and color of the firefox scrollbars with a system CSS. Since a firefox update to version 98, firefox ignores those settings. Nothing has changed in my firefox settings, my about:config, or system settings. But now the scrollbars are barely visible low contrast narrow bars that are unpleasant to work with, and I can't figure out how to change this. suggestions? tnx

I'm using Firefox Version 98.0.2 on Ubuntu 21.10 with Wayland and Gnome 40.4.0. I choose a larger cursor size from Ubuntu's Settings->Accessibility->Cursor Size. However, in Firefox the cursor always displayed in the smallest size.

I installed Rust on my laptop and want to browse to the documentation which is installed at file:///home/lochlann/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/intro.html. I try to open this in Firefox and this fails with the message: Access to the file was denied

The file at /home/lochlann/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/intro.html is not readable.

   It may have been removed, moved, or file permissions may be preventing access.

I have read permissions on the file. No matter, it fails. I try to open the file using Firefox and navigate the directory structure rather than typing in the location. The file opens in the browser, the location is listed as file:///run/user/1000/doc/1f137432/index.html. Can you explain to me why Firefox cannot render a file that is where i put it and has appropriate permissions yet can render the same file where I did not put it? I have always been a fan but this looks more like a virus than I am comfortable with.
