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`:

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.

When printing emails and webpages in Firefox, the font is always huge. I mean HUGE (40pt??).

I have tried so many things (changing scale/print preview settings, troubleshooting from the Firefox menu, checking for software/driver updates, turning the printer/computer (Windows 10 laptop - new) off, checking printer settings in some weird config menu in Firefox, changing the default font size/zoom (this changes how I see it but not how it's printed) ARGH!!!!!)

NOTHING WORKS. Where there is a forum or help tip, I've tried it. Where it has worked for others, it does not work for me. Chrome works fine. Printing to PDF works fine.

Aha, you say, it must be my printer (HP smartank 450)! Well the nice folk at HP have spent hours trying to fix this and have no clue. I am about to give up on Firefox. Can anyone help??

I know this is an old issue. I'm getting it now, FF 90.0.2 64-bit, Windows 10 Pro N, Build 19041.vb_release.191206-1406. System updated. Not very often it starts playing for a fraction of a second. Videos and GIFs everywhere else (as far as places I normally go) plays as it should. Troubleshoot mode didn't solve it; hardware acceleration tweak neither. No crash logs.

Tried on the Edge and everything is fine.

Question: does the suggested "fix" on https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows embraces this issue as well? If so, sorry, but might be time to change browsers. The reason I'm using Windows 10 PRO ->N<- is exactly not to have to remove Windows Media Player and related "bloat" from my system. This isn't one of those crybaby threats I hate to read: it's a necessity.

I must ask: why on Edge, on the same machine, the same problem doesn't exist as in Firefox.

Suggestion for mentioned article: might be helpful point users (also) to the right place of The Media Feature Pack for N and KN versions of Windows 10, on https://www.microsoft.com/en-us/download/details.aspx?id=48231

Thanks

I started Firefox yesterday and saw a message about not having been on for some time - which rang alarm bells for a daily user! Having time today to investigate, it seems that it's lost 6 months of history and bookmark changes (I'm only offered January or today!) Is there a way of recovering all that history (very helpful) and this Tuesday's bookmark set? Thanks Stephen

Firefox for Windows make major change in Toolbar in version 89 upgrade: New in version 89: Say hello to a fresh new Firefox, designed to get you where you want to go even faster. We’ve redesigned and modernized the core experience to be cleaner, more inviting, and easier to use. Beginning in 89, you’ll notice a number of changes, including: Simplified browser chrome and toolbar: Less frequently used items removed to focus on the most important navigation items. How do I avoid Firefox deleting lesser used links in my Toolbar? They are there for a reason.

Hi! When I adjust a volume (Ej. 30%) elsewhere, when change the focus to Firefox browser, the volume automatically raised to 100% no matter if the page or pages are in blank or with content. And when I change to other application, the volume is back to original state (in this case 30%). Yes, it changes system volume, not the app volume. Searched all over internet and couldn't find solution.

Tried: - Deactivate all sound enhancement. - Deactivate sound lowering in call. - Change sound card (realtek to Nvidia) - Change output (back panel, front panel) - Updated drivers - Unplugged periphericals - Deactivate Control media via keyboard, headset, or virtual interface - Changed media.default_volume in about:config Nothing works

This only happen with Firefox and Chrome browsers. Microsoft edge, games and other multimedia apps has not problem.

I am using AMD Ryzen 5600X Asus TUF b550m 16GB RAM

Firefox 90.0.2 Windows 10, Version 20H2, Build 19042.1110

Hope we could find a solution. This is very annoying when using a headset. Regards

I wrote a message in GAB chat but just as I sent it I lost internet . The message is gone but not delivered. I searched online how to recover and followed instructions to do this. type or paste about:cache in the address bar and press Enter. Under disk click the link to List cache entries. This may take a long time.

Eventually you should see a list that lets you find the URL you're trying to decode. If you click it, Firefox should show the content there and list the compression type, which most often will be:

Content-Encoding: gzip

In that case, if you save the encoded content to a new file with a .gz extension you should be able to decompress it using your favorites ZIP utility. Of course, finding the beginning and end of the content may not be intuitive. I don't know whether the cache entry info page is helpful or not.

    The problem is I have no idea which item in the vast list is on GAB because they all say google and Firefox thanks for any advice and please tell Firefox we are extremely disappointed that they teamed up with commie Google we can no longer download you tube videos unless we go through chrome and the downloader they offer uses 3 time as much data in the same format as the down loaders we were able to use

I upgraded to V90.0.2 and tried to install Pocket. The popup gave me an old email address that does not exist, so I changed it to my current email address, logged in, but then pocket said it needed to use my email address, but the old email address was in the box and there was no way to change my old email address.

I came here and logged in using my old email address, but I had updated the account so it had my new email address. I logged out and logged in with my new email address, and my settings were the same, with my new email address and my new alternate email address.

No where was my old email address listed for me to change or delete. I see no way to tell FF that email no longer exists. Confusing, I know.

especially on startup, i get two 'windows' open. that is, instances. it happens because sometimes i click on firefox and nothing happens. if i decide too soon that it is not going to load, i click again and it then loads twice, and i get the nonsense about firefox already running. if this cannot be fixed, i would like to select allow only one instance to run as VLC offers.

I would like to be able to have two rows of tabs so things did not get so cluttered, but only if it is something like f8 to switch. since dos was squeezed out, nobody is using the f keys anyway.  :(

The new Firefox is very disappointing and a big let down. I have been a dedicated Firefox user but these recent updates have made Firefox extremely slow and some of the useful functionalities are no longer there... Furthermore, with the previous versions, I would create my own short cuts by pinning them somewhere on the browser by either dragging the website address, or their logo and then by right-clicking the pinned tab, I would just type in a brief name to know what site it belonged to. Now, I can do it, but only to well-known sites such as Amazon, Facebook, Ebay and so on. I cannot do it with my own-interest websites. My own-preferred websites do occupy a space above the browser, but I cannot add a name to them. The little transparent square is just empty and I am unable to give it a name.

And, what is worse, when I open the new Firefox, all those pinned sites are being opened in the background and all the same time, and thus it is taking ages for me to get to my Home page. So far, with every update, I have lost certain functionalities which I had before.

I am sad to say, I might be tempted to start using Microsoft Edge on which I am still able to use these functionalities and at three times the speed compared to the new Firefox.

You have also done something lethal when uninstalling and reinstalling a Firefox browser. I have LOST all my bookmarks. In the past, the bookmarks would sit somewhere on the computer to be re-inserted with the new installation of Firefox. This is lethal and I am furious about it. I know, I know, I can export and re-import my Bookmarks, but it is not the same, I tell you.

You've done something with these updates which are not fit for purpose, I'm sorry to say.

I would like to at least be able to return to my own pinned short cuts at the top of the browser to make me use Firefox rather than going to the Bookmarks for my frequently sites.
