I-Firefox Community Forum

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

Greetings Firefox Community

As I long time user and supporter (have donated and even got a shirt to show!) I have never had any issues with my beloved FF. If anything minor had happened, I would always find a quick fix on the community forums.

This one is an odd ball: for a while now Firefox forgets all saved passwords but only after a cold reboot (not a restart or sleep).

It's my elderly mum's laptop, which I manage for her using a remote desktop app. It's a fairly new Asus Vivobook with Win11, fully updated and free from viruses and hacks as we have installed paid versions of both Malwarebytes and HitmanPro.Alert. My Windows desktop runs exactly the same OS and those two security software, and my FF never ever forgets anything! The only difference is that her Windows and FF are set to the Italian language while mine is English.

After trying a "refresh", I exported her passwords and bookmarks and took the drastic step of completely wiping FF and even removing profiles. Reinstalled the latest x64 version and the problem is still happening.

Had a good look at both security software to ensure there was no funny setting to cause that to occur, fact is the laptop also runs Chrome and Edge with all the same saved passwords yet those two pesky browsers never forget anything!

Personally, I'd much prefer for her to continue to use FF rather than the other two, so I am shouting out for HELP, please! Hope someone has seen this and/or knows how to fix it.

Many thanks in advance and Merry Christmas to all! Cheers Paul Perth - Australia

Hi--

I recently upgraded from Mojave to Sonoma 14.2, and Firefox 120.0.1.

In Mojave, fn-F12 used to invoke a "Dashboard" with applets like Dictionary and Thesaurus.

With Sonoma, fn-F12 causes the bottom part of Firefox's frontmost window to become a web developer tool, same as ⌥⌘I, instead.

Can I get my Dictionary and Thesaurus back?

When trying to click on links inside PDFs, the url is changed to undefined, producing an error message. For example, a Hostgator article is converted from https://hostgator.com/help/article/how-do-i-change-my-dns-or-name-servers to https://undefined/help/article/how-do-i-change-my-dns-or-name-servers

I have tried clearing the cache, troubleshooting, and get the same result in safe mode, and reverting back to Firefox default settings. And I still get the same result. I've attached an image of the error message.

I am using Firefox 120.0.1, and I have difficulty to take screenshot.

I tried to press shortcut key and button in toolbar as shown in the attached image, but they didn't work.

Is there any good way to fix this problem without reinstall firefox app?

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

I think it has to do with cookies, but I can't figure out what to fix. I have my tracking privacy set to strict. Twitch has permission to use my cookies and site data (Settings -> Privacy and Security -> Cookies and Site Data -> Manage Exceptions). All of the other websites that I have granted that permission to have no problem remembering my device, but Twitch does. I looked at this post already and my account was already set to these settings. How do I make Twitch remember by device? It's annoying to have to go to my email and use a one-time passcode every time I log in.

I set the browser to Open previous windows and tabs at restart, on General settings, but it always opens blanc, not saving any tab from the previous session.

How can I correct this issue, if it is one, please?

I have a new PC running Kubuntu 22.04, with Mozilla Firefox 120.0.1 (64 bit) installed. Standard, the system window title bar was hidden. But I wanted access to the "Move to desktop" menu and wanted the title in the title bar. So, in "Customize toolbar" I checked "Title bar". The title bar reappeared, but a complete border along the Firefox window became inaccessible, and when clicking in that zone, it effectively clicked in the window behind. In particular, the complete menu bar is inaccessible, as well as the scroll bar on the left and in the bookmarks sidebar the fold/unfold. And Mozilla Thunderbird 115.5.0 has the same annoying behaviour. Even when hovering over some menus in the Mozilla window, you can sometimes see reactions from the window under the Mozilla window. On older Kubuntu computers (up to 18.04) with older versions of Firefox (up to 113.0.2) and Thunderbird (up to 102.11.0) I do not have that problem. How can I get at the same time access to both the system title bar and the menu bar ?

Hello, currently using 120.0.1 (64-bit) for macos and would like to know how to change behavior: When i'm trying to modify url in tab i'm currently working on and press enter/return it opens modified url in new tab for some reason. But when i hold option it opens it in current tab, is there any way to make it as default behavior? Thank you very much👍

Open this url https://openfde.com/intro.mp4 and firefox shows "video can't be player because this file is corrupt".

Chrome is fine.

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).

When visiting some smaller and less known websites on my computer it shows the error message "connection has timed out" but on my laptop it loads just fine. Both run firefox and are sync'd with the same configuration and extensions. I already tried the troubleshoot mode and also checked the firewall. Is there anything else I can try to fix this?

Whenever I open Firefox, it opens every tab from my previous session. I don't want this - if I closed the window, it was because I wanted it closed, and I don't need any automated system to re-open everything on the off chance I was wrong. I believe the setting for this is on the General tab, but as you can see in the attached screenshot, it's definitely off, yet the feature won't go away. I also tried changing the config settings, as listed here:

https://askubuntu.com/questions/1285172/firefox-always-restores-windows-and-tabs-after-reboot

, but it had no effect.

How do I stop Firefox opening these tabs without permission?

Foxnews.com causes Firefox 102.0.1 to freeze when scrolling pages with lots of images. Closing and restarting FF does not help. The freeze reoccurs. What does help for awhile is to delete the file places.sqlite. After that FF runs for a few hours until the problem happens again. Is there a setting or other fix for this issue?

AdBlockPlus and uBlock Origin are both installed, but are disabled on www.foxnews.com.

For whatever reason, I can't find a simple way to file a bug report. Starting 120.0, or maybe in 120.0.1, I've started seeing a cursor appearing next to buttons and other components on web pages that you definitely would not expect to see cursors next to.

It seems that a cursor has started to display when I click on web components even if it's not a text entry field. I've included a screen shot that includes a cursor appearing next to the Refresh button in Gmail, for example.

There's even a cursor appear in the "Browse" button on this very page in the Add Images section.
