For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

I have been fixing dozens of problems with 140 ESR's GUI. Earlier today I fixed almost all of the problems with the search panel:

Except one: I do not know how to detect when the default search engine has changed. I need to know how to detect when the default search engine changes so I can update the favicon and placeholder text by recalling my gui_fixes_search_favicon() function in userChrome.js.

I'm an experienced web developer of 20+ years and would be grateful if someone could share their insight without the often "obligatory" cautionary tales 101 bit. Thank you in advance!

When I click on KPN TV+ I see a message: Firefox is installing missing components, try later. But Firefox is NOT providing missing components.. Or is the problem that KPN (and Ziggo IPTV) can NOT run on Linux???

'bold text'bold textHow do I fix this step by step? To create an AppArmor profile for Firefox:

In /etc/apparmor.d/, create a file with the name firefox-local

In the file, add the following:

1. This profile allows everything and only exists to give the
2. application a name instead of having the label "unconfined"

abi <abi/4.0>, include <tunables/global> profile firefox-local /home/<USER>/bin/firefox/{firefox,firefox-bin,updater} flags=(unconfined) { userns, # Site-specific additions and overrides. See local/README for details. include if exists <local/firefox> }

Replace <USER> with your Linux user name. This assumes the Firefox install is at $HOME/bin/

Once you have saved the file, run sudo systemctl restart apparmor.service in the Linux terminal.

ATT is my internet service provider. I use their website as my home screen. Yesterday, I started getting an error message when I tried to go on-line. I have contacted ATT, and they have determined that the problem is with Firefox, and not their website. I can go from the ATT screen to any other website, and it works fine. This is the message that I get:

Secure Connection Failed

An error occurred during a connection to www.att.com. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

My husband and I both use Firefox as our default browser. His macbook air did an auto update of his firefox and now he has no bookmarks, no search history and none of his many open windows are there. He has to file his timesheets tonight so we can get paid in a month's time. What help can you offer? His email if [edited] @telus.net and he can be reached at [edited phone# and email from public support forum] We are in the Pacific Time Zone.

Last few days I've been getting this popup:

Attention!!! Click to turn on the antivirus

or

Attention!!! Click to scan the device

obviously some phishing or something. How can I get rid of it?

Below are two attached images, please take a look. From my understanding there are two different translation features built into firefox, you can identify them by looking at the attached screenshots. I very much dislike the translation features which has the "page icon". The other option which looks like an "alphabet icon" and has "EN" attached to it is very much welcome. I want to add this translation feature to the toolbar, however when i open up the "customize toolbar option" there is no translation feature available. How can i add it? I do remember that in previous firefox version, the translation feature was pinned to the very right of the bar.

Hi! Why I lost the customize button on my Firefox's home page? This happened after the last Firefox upgrade.

Your help will be greatly appreciated.

I am using Tor browser, which is based on Firefox. The 'About' tab says this: 14.5.6 (based on Mozilla Firefox 128.14.0esr)

When I sign in, it tells me that: "Some of Tor Browser's security features may offer less protection on your current operating system."

And it directs me to the following page: https://support.mozilla.org/en-US/kb/linux-security-warning?as=u&utm_source=inproduct

-- which directs me to set up a file called 'firefox-local' with specific contents. I have created this file; and pasted the recommended contents into it, and saved it.

I am then directed to issue the following command: sudo systemctl restart apparmor.service

-- which I have done. But that returns the following error: Job for apparmor.service failed because the control process exited with error code. See "systemctl status apparmor.service" and "journalctl -xeu apparmor.service" for details.

systemctl status apparmor.service gives the following output: × apparmor.service - Load AppArmor profiles

I don't know how to make heads or tails of this. Apparently the profile failed to load. According to the file documentation, it expects firefox to be located in '/home/<USER>/bin/firefox/' but I am running a version through Snap. and I think it is installed in '/snap/firefox/6700/usr/lib/firefox/firefox'

Is that the trouble; and how do I fix it? Grateful for any assistance; sorry for the data dump.

I don't understand! I'm able to order merchandise on other websites, including Mary Kay's. Why is this any different? They are May Kay business cards for my Mary Kay business! (I'm also 93 and not very savvy about this.) Please help. Ellie

Добрый день. Пару недель назад после очередного обновления браузера (использую ESR, на данный момент моя версия - 128.14.0esr (32-разрядный)) столкнулся с проблемой. Раньше, если я открывал через ссылку на любой странице новую вкладку, она сразу же грузилась через VPN-дополнение. Но сейчас любая ссылка при открытии новой вкладки будто бы открывает страницу по дефолту - и не грузит вообще ничего, может больше минуты пытаться загружать, а потом просто остановиться и повиснуть. Помогает только полное обновление страницы или скопировать ссылку в новую вкладку (можно в той же открывающейся и зависшей вкладке просто нажать "энтер" в адресной строке, тогда браузер всё обновит и загрузит как положено - через VPN). Проверил на нескольких VPN - везде такая фигня. При этом если заранее открыть новую вкладку и просто скопировать в неё ссылку - всё загрузится моментально. Однако это очень муторно делать, когда одновременно со страницы открывается по десять новых вкладок.

Это баг или какая-то новая поднастройка у вкладок, что они открываются по дефолтным настройкам?

I want to know what should I change to change between these two appearances. I tried to change everything with `browser.search` in about:config, but I don't see anything that changed it.

My Firefox Updated today and just closed randomly, on reopen it was brand new with no history/bookmark etc. I didn't have a firefox account at the time. Is there a way to restore it since i used a lot of mozilla auto set passwords which have also been deleted.

The fucking forced dark mode has return despite the previous fix layout.css.prefers-color-scheme.content-override = 1 in about:config fixing it for years. This and the current replacement fixes don't save. I want a solution for PERMANENT light mode (black text on white background) for ALL menus, pop-ups, dropdown menus and hover over tab info.

And don't tell me to go search for a different theme I've already spent hours doing that and firefox has broken them only making some menus use the appropriate mode. On top of that I can't even pick an option to search for one that uses light mode I just have to go through each one and try it if I want to know which mode it uses that is NOT a solution to anything.

Replacement "fixes" for reference: ui.systemUsesDarkTheme won't even let me set to 0 only has true/false browser.theme.content-theme set to 1 browser.theme.toolbar-theme set to 1 (Why in the absolute hell these were added when a simple addition to preference setting wasn't is beyond me)

Very sorry for the aggressiveness but I am so very VERY tired of having to fight firefox on this preferance for years when their dark mode hurts my eyes.

Since the last update (was executed today in my case 16-07-2024), firefox has been very slow and freezing and crashing. Also, somehow it is the only browser that can't handle yahoo finance new charts and keeps freezing....so many issues in a short span of time, please check. I have tried other browsers and things seem to work fine there, so, it is not my computer or OS.
