Firefox fails to resolve local/VPN DNS

I am using Firefox on Linux (Ubuntu 20.10) to work from home over OpenVPN. Recently the VPN configuration was changed to use split tunneling to improve our internet connection. Since then I have had several DNS resolving issues in Firefox.

We use an on premise DNS server as an alternative to `localhost` domain names so we can access other developers' environments and so a few services can do the same. Our URL structure is like projectname.[optional personal identifier.]localhost.[type].nl. Without the [optional personal identifier], or when nothing is configured for it, the ip address is 127.0.0.1.

In Linux' OpenVPN configuration I have "Use this connection only for resource on its network" enabled for IPv4 and IPv6 is disabled (to benefit from split tunneling). With that enabled Firefox usually fails to resolve such development hostnames.

- As far as I know I do not have DoH enabled (and the about:networking log further down tells so too). - I do have `dnsmasq` enabled (with configuration for the above domain formats to route to 127.0.0.1 also) in an attempt to fix some issues before the split tunneling was configured correctly. And in an attempt to try and get Firefox to handle these DNS resolving issues. - `dig` on the command line for the same domain works just fine. - Adding hostnames to /etc/hosts works. But that's becoming a chore, working on dozens of projects over months.

Why is Firefox failing to resolve such domain names? Should I just create a Bugzilla issue?

I created a log with about:networking set to `timestamp,nsHostResolver:5`:

After the last update to version 90.0, I can't continue to use firefox browser. The problem is about opening google sites (youtube, gmail). Other websites seems to work normal, but I can't open youtube and gmail now (google.com itself works heavily). When I type url and click enter, it takes so much time to load, often not loading the site or partially load. Other browsers installed on the same system works normally with the "problematic" websites. I tried hard reload (ctrl+f5), cleaning all browser data, and uninstalling and reinstalling. None of the mentioned actions helped. Please help me to identify and solve the issue.

Since a couple of weeks my Firefox browser for Windows 10 64bit has issues. Last update 90.0.2 did not work either,and the issues is still there.

Internet is extremly slow,some sites will not open and i cant logg in to Facebook.

Under settings,i have tried different settings. Right now i have the standard setting. Under Help,i have tried to restore,diagnos and clean catch and restart,but it has not solved the issue.

What could be causing these issues? Do i have to do some special settings or do i have to add some Add-ons/Extensions in order to have Firefox work normal again?

For the last couple of months I've been having an issue with Firefox freezing when I bring up a news article on Yahoo. It only happens when there is a video attached to the article, the video and the text of the article won't load. After a few minutes there is a message saying "This page is slowing down Firefox. To speed up your browser, stop this page". All of the Yahoo news articles work fine when I bring them up in Chrome. How can this be fixed??

I am using linux kde neon on wayland. Firefox version 90. On ubuntu with gnome 40, my touchpad zoom works. I didn't have any problems on kubuntu either. But on Kde neon, gestures don't work. I forced the MOZ_ENABLE_WAYLAND = 1 setting to enable wayland support. About: support shows that wayland is supported by the browser. Also I tried the settings MOZ_USE_XINPUT2 = 1 and GTK_USE_PORTAL = 1, but they didn't help either. Gestures in the system itself work.

Hello Mozilla Team,

I have a small problem.

My home server was killed by a flood, so I lost my password manager (2FA & recovery code). The geo backup was unfortunately a bit older and does not contain the data for my Mozilla account. This has now locked me out of my account, but I still want to delete it. I have read the article (https://support.mozilla.org/en-US/kb/what-if-im-locked-out-two-step-authentication), but I still have the right to delete my account and have my data deleted.

I would like to know who to email to get this started, Stay healthy, thanks for the help.

I have Firefox on a couple of (Windows 10) PCs. This problem is happening on one of them. It has two profiles (users), and it's happening on both.

If I open Firefox, and then trying going to google.co.uk, or do any google related search, almost everytime there is an obvious 30-40s delay. Indeed, during this time I can even open up other web sites (immediate), and trying google.co.uk again, and delay continues to occur.

Opening up the Network Console in Firefox, the GET request can be seem and then like clockwork there is about a 41000ms delay until it then continues.

If I open in TroubleShoot mode, same issue.

If I open in a Private Window, the problem does NOT occur.

This problem does NOT happen on my other PCs with Firefox, or any other browser on the PC in question.

This is very frustrating :( You open firefox to do a google search and it takes tens of seconds to resolve (on the first attempt) :(

Hi! I am trying to use the Multi-Account Containers add-on in conjunction with Facebook Container and Temporary Containers add-ons.

I have DuckDuckGo set as my default search engine, and Homepage and New Tabs and Windows set to Firefox Home.

Firefox Home has no domain in the address bar, which is presumably why it is always opened in a temporary container.

I am not sure I understand the best practice to use them after reading a LOT on various sites. Aside from the default containers, I have set up specific containers, depicted in the attached image, for: -Privacy Expected (Firefox, DDG, etc). -Often used and generally trusted (labelled Suppliers, Sites I like). -General sites which I expect to visit again, and I've managed cookie settings I don't want to do again each visit due to Temporary Containers add-on deleting their cookies. -Yuk Sites I expect to track me can go in a container (again, only adding to a container so I don't have to manage their cookies each visit). -worst offenders have their own containers (Google, Microsoft, etc)

Still trying to get my head around how to set permission for add-on Read Aloud to use Google Wavenet voices, and have that permission (and "I am not a robot" Captcha) seen across non-Google pages I want to be able to be read aloud (maybe have to add that 1 page for Google Wavenet voices to an exception in Temp containers or no cointainer but at the extent of my ability to make sense of all this).

Hello,

I'm not able to get a download popup when I left click to download (anything) - only if I right click and select save file as i'm able to save it and download the file - something prevents the auto download from flowing properly.

if i run on safe mode there is no problem and i can download it - I did all of the explained here: https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems I also disabled all of the the add-ons or disabled them one by one but it didn't help to locate the problem - still can't download on regular mode.

I refreshed firefox, deleted & reinstalled it and with a new profile its the same as safe mode - no problem. I copied the files from the old profile to the new but the problem returns.

Any suggestions on how to locate the problem?

thanks!
