I'm wondering if there is a compatibility issue with the built-in Firefox VPN and the DoH settings. I have the DNS over HTTPS set to 'custom' with the default option of Cloudfare

With the VPN turned on 1.1.1.1/help shows that I am not connected or using DoH, but the second I turn the VPN off I am connected and using DoH. It seems that the Firefox VPN uses Fastly as its DNS and not the DoH settings I selcted.

Is there a way for the VPN+DoH to work together? Admittedly I'm very new to trying to be more secure/anonymous on the internet, but I was under the impression that having both is better than one or the other.

Am I missing something?

To get straight to the point, I use the website https://ingrails.com/school/. I've noticed an issue: when I try to print certain contents from this site using the Mozilla Firefox browser, the borders don't show up in the print preview and they don't print either. However, I don't face this problem with Edge, Chrome, or Opera. Why does this happen, and what is the solution?

I have attached some screenshots for reference. The screenshots showing the borders were taken from Edge, while the ones without borders are from Firefox.

I'm on 156.0b1 (64-bit). Since the last update the data that should appear on https://www2.commsec.com.au/portfolio/ no longer appears. The page works fine on Edge, Safari.

The rest of this site all works perfectly - it is only the data missing which is specific to my Commsec account holdings..

I can't say for certain that it was absolutely the update that's the cause - beyond my skill level - but the problem commenced from that time

Any ideas please?

Thanks

I've been using the split view feature and really like it... however I constantly find myself doing the following:

Having a split view open with related pages, for example a list view in the left pane, and I want to open one of the items in the list view in the opposite pane, currently I have to:

1. Copy the url in the left pane 2. Switch to the right pane 3. Target the address bar 4. Paste the url 5. Load the new url

Ideally an additional 'open link in x' option could be added specifically when a user is in the split view, that will open the link directly in the opposite pane of the current split, so left > right or right > left.

My question is, is there is a way to do this already; I cannot find any reference to this in the docs.

"Open Link in Opposite Split View" would be perfect.

Здравствуйте, подскажите, можно ли войти под одним профилем но иметь разную панель закладок? Например я вошел под профилем для поиска информации в браузере и есть панель закладок для браузера, которыми пользуюсь. Также я скачал Firefox Developer Edition также вошел под тем же профилем, но хочу чтобы панель вкладок была своя, и не пересекалась с обычным Firefox. Можно ли так сделать? или нужно создавать вторую учетную запись для разработки в Firefox Developer Edition

Environment

   • Firefox 153.0.1 (64-bit)
   • Ubuntu 24.04.4 LTS
   • Wayland session
   • Input method: IBus
   • Keyboard layouts:
       ◦ US
       ◦ Bulgarian (bg+bekl)
   • Graphics:
       ◦ AMD Radeon Graphics (renoir)
       ◦ WebRender (Software)

Summary When typing a multi-word search query in Bulgarian into the center search field on the Firefox New Tab page (about:newtab), the first word disappears immediately after pressing the Space key. The issue occurs only in the in-page search field. Typing exactly the same text in the Firefox address bar works correctly. Steps to reproduce

   1. Open a new tab (about:newtab).
   2. Click inside the center search field.
   3. Switch to the Bulgarian keyboard layout.
   4. Type the first word, for example:   български
   5. Press the Space key.

Actual result The first word disappears completely. The search field becomes empty and the caret remains after one blank space. Typing continues normally from the second word onward. Interestingly, pressing Ctrl+Z immediately restores the missing first word, indicating that Firefox performs an undoable edit operation rather than simply ignoring the input. Expected result The first word should remain in the search field after pressing Space. Additional observations

   • The problem does not occur when typing in the Firefox address bar.
   • The problem does not occur on google.com or in other web page input fields.
   • The problem is reproducible in:
       ◦ Troubleshoot Mode
       ◦ a brand new Firefox profile
   • No third-party extensions are installed (only the built-in OpenH264 codec is present).
   • Setting

browser.newtabpage.activity-stream.showSearch = false removes the in-page search field, therefore the issue disappears because the affected widget is no longer present.

   • Disabling

browser.search.suggest.enabled does not change the behaviour.

   • If the address bar already contains text before clicking into the New Tab search field, the issue may no longer reproduce. This suggests that the bug could be related to focus handling or interaction between the New Tab search widget and the address bar.

Reproducibility Always reproducible on this system. Notes The issue appears to be specific to the Firefox New Tab search widget (about:newtab) rather than to the operating system, keyboard layout, input method, or user profile. ____________________________________________________________ The text above was created following extensive discussion and numerous tests, in collaboration with ChatGPT.

Running Windows 11. Firefox was running at the time the hard drive crashed. When installing FF on the new drive, found the last profile folder set to parent.lock. Since it's the entire folder, I can't see which of the files in the profile were locked. I have a backup of two weeks prior (separate issue -- I was unaware my nightly backups weren't working for two weeks), but I'd like to recover the bookmark and password changes in that time.

Is there a way to get into the folder, or do I just need to accept the loss and go with the previous backup?

Hi,

if I try to open an uploaded project, Firefox shows me just the "Loading"-Animation. This war reproduced on several PC's, using a clean profile and the Error-Modus (without Addons). In Firefox fpr MacOS it works.

Knows anybody the problem or can help fix it??

Greetings, Christian

Firefox is saying that there is a problem with my Xfinity internet & advises me not to log in. This happens only on my mac. Firefox seems to work fine on my i pad & i phone. Safari does not show this warning & they are very strict about internet issues. how do I fix this problem?

My VPN has. stopped working although it has reset as it does monthly, worked fine a week ago, Still have 50 gig and won't engage with server? any help appreciated....

I was creating two-factor authentication for my account and when I tried to create a passkey the only options were to use iPhone, iPad, or Android device, or Security key (see screenshot).

There's no option to add the passkey to a password manager (I'm using BitWarden).

I'm using Firefox Version 155.0 (64-bit) on Windows 11 (25H2).

How can I change preferred theme from light to dark with resist fingerprinting enabled? I already tried to change "layout.css.prefers-color-scheme.content-override" to 2, but this did not help.

The server not found response started right after two changes: 1) Firefox last update 2) opening an account with Mozilla. It usually works on second request but occasionally not. Thanks for your help in advance.

1- Firefox shows I have windows 10. Not so. I have windows 11 home, version 25H2. This may be problem that causes the issues. 2- Since Update months ago, profiles, bookmarks and passwords disappear constantly only for me to replace manually the bookmarks and passwords to disappear over and over again. Don't need multiple profiles just one that works as in the good old days. Used it for years but cannot find help and ready to delete and just use microsoft edge. Totally out of patience. ?????????????????????????????????????????????????????????????????????

Running 154.0.1 on MacOS 26.6.1. Sometimes firefox stops working and I think I'm having an internet issue. No page able to load, not even a google search. I see the cache is full at 1gb and I clear cache for the last hour. Browser starts working again. To me, the problem doesn't seem like not enough cache capacity but the browser refusing to evict old, stale cache. How do I fix this other than manually clearing the cache? This seems like a bug that should be fixed.

I got a message Firefox software was not updating. I was sent a download in .exe link. ALL of my tabs are not accessing the addresses. I checked Restore All Crashed Tabs. No resets are happening.

Is this due to a bug in the upgrade? What are Mozilla's actions to fix this. I have used Firefox successfully on my high end HP OMEN PC. I do all I can to avoid Microsoft, Google, etc.

I need HELP.

Hello!

It's great there is finally a way to change keyboard shortcuts. However, I cannot find a way to change the keyboard shortcuts for previous and next tabs. Ctrl+tab and ctrl+shift+tab are not very comfortable positions. I would much rather have it something like ctrl+alt+left or right.

Is this something I will be able to do soon? or maybe the setting is there and I am just being blind?

Thanks
