I start FF in safe-mode. I open a local page which includes only one URL. When I hover on this link I see (`tcpdump`) a DNS lookup being performed for this domain. I followed the suggestions from Mozilla but I still see this.

How do I stop this access.

I use FF "156.0 (64-bit)" on Fedora 44.

TIA

Firefox version 152.0 : Firefox is continuously refreshing the page on a particular Website, in both Windows11 and Linux versions, making the site unusable ( unable to click anything ). The website loaded ok previously using Firefox and still loads ok using Chrome. Disabling extensions doesn't help, neither does deleting the cache and cookies. What changed and why? Is there anything else to try?

Dell desktop running Mint Mate 22. Bookmarks missing about 50% of bootups. Saved bookmarks to both HTML and JSON during an occasion they did appear, when they next were missing attempted to restore them via Library pop-up (Manage bookmarks). I could not determine a path to direct the system to either locally saved file. In Library, selected Restore, which then asks me to choose file, but none of the data fields accepted or acted upon input. re-installed Firefox but same result. Then clicked on the saved HTML file, multiple screens flashed on the display, with multiple items in the tray. The final result was the bookmarks were all displayed as expected, but since the problem has been inconsistent, unknown whether they will display on future bootups.

Wish to have guidance on using the Library pop-up to restore saved bookmarks when they are missing. Perhaps some knowledgeable user could post a step-by-step through the restore process.

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.

Hello! I'm on Debian, and there Firefox ESR is the default browser, it is now basically unusable as it is so out of date that Cloudflare Turnstile no longer works.

This is a major problem.

I have opened a ticket over at Cloudflare, but they have not commented at all on the problems: https://community.cloudflare.com/t/turnstile-not-woring-for-the-last-few-days/939637

Thank you for your time.

Hello all, thank you in advance for your time. I've got a Lenovo running Linux (Zorin, an Ubuntu branch)

Crashes have been more and more frequent over the last couple weeks. Usually it closes only Firefox, sometimes it throws me back to the login screen, and rarely the computer crashes entirely. I've been trying to pin down the source of the crashes -- it hasn't only been Firefox, but most of the crashes are while FF is open.

THIS tab keeps crashing, as I type.

It seems to happen more often when I'm watching video.

Here are all the crash IDs within the last 24 hours: bp-dfb0bd40-4ce6-41bd-b9cb-ad0510260913 13/09/2026, 11:15 View bp-50a8400a-3439-4af4-b5c7-6e60f0260913 13/09/2026, 11:15 View bp-0893e979-6a06-40cc-ad0b-757210260913 13/09/2026, 11:15 View bp-8a1bbc36-9c1d-412c-a2cf-c4c040260913 13/09/2026, 11:15 View bp-4c97e699-dee7-470f-9f82-855760260913 13/09/2026, 11:15 View bp-4526b2af-908a-45be-89ae-293ef0260913 13/09/2026, 11:08 View bp-60af27d7-aeef-4761-b86e-7595a0260913 13/09/2026, 11:08 View bp-25b42dd1-3f54-4be4-bde7-801f60260913 13/09/2026, 11:08 View bp-e92ad4f9-b7d3-453e-8c5a-066910260913 13/09/2026, 11:08 View bp-d19f0c4c-9eb7-45d1-a7e7-978d90260913 13/09/2026, 11:08 View bp-b212719f-1daa-459c-8491-2c6cb0260913 13/09/2026, 11:08 View bp-9effc3ad-0b73-43d2-839c-805a00260913 13/09/2026, 11:08 View bp-7e5b6de1-7a84-48ad-86c0-e07510260913 13/09/2026, 11:08 View bp-271c4c4f-9f81-480a-9815-5f5bf0260913 13/09/2026, 11:08 View bp-956cef3e-25a1-4a8c-b7e1-668be0260913 13/09/2026, 11:08 View bp-92a596e6-edc8-4920-9365-6e3e00260913 13/09/2026, 11:08 View bp-6e309137-bf0a-4ee1-8ddf-492b20260913 13/09/2026, 11:08 View bp-d3eadcae-1967-4c31-856f-284f80260913 13/09/2026, 11:08 View bp-e319008d-d7e3-4354-95db-846e10260913 13/09/2026, 11:08 View bp-ce80cf98-4aad-46ee-a2a2-40ccf0260913 13/09/2026, 11:08 View bp-41734b4e-09d0-4dfe-ab7a-c74400260913 13/09/2026, 11:08 View bp-37752c09-a2ae-4f35-8ee6-62ee60260913 13/09/2026, 11:08 View bp-01aed5a5-d3da-4551-9646-eb73d0260913 13/09/2026, 11:08 View bp-0d52d173-f46d-4d5c-b723-441930260913 13/09/2026, 11:08 View bp-5a9507dd-21f3-4be3-8d68-ad70f0260913 13/09/2026, 11:08 View bp-0a5b5b7c-6400-41f7-ba67-c881b0260913 13/09/2026, 11:08 View bp-2ff2f687-e231-4ac5-925a-fde060260913 13/09/2026, 11:08 View bp-1c9a1836-3ebe-40bd-ac76-182850260913 13/09/2026, 11:08 View bp-f4bbc332-be5c-48f7-8e6e-c008a0260913 13/09/2026, 11:08 View bp-807e438c-9bb1-4056-b67b-48e870260913 13/09/2026, 11:08 View bp-b422a84c-4096-4ab8-926c-d63030260913 13/09/2026, 11:08 View bp-9740f00f-a1ac-4fce-96b3-704940260913 13/09/2026, 11:08 View bp-0a571a75-602f-4802-98df-22ee30260913 13/09/2026, 11:08 View bp-5f7a41ac-f92a-42b3-96bc-6dda70260913 13/09/2026, 11:08 View bp-d81a88f6-3da4-4e15-8669-352390260913 13/09/2026, 11:08 View bp-324a6102-496b-4724-9deb-3532f0260913 13/09/2026, 11:08 View bp-40969791-0669-4158-abd6-b57230260913 13/09/2026, 11:08 View bp-7b5c8e37-6cfe-4027-9bd1-fc0d80260913 13/09/2026, 11:08 View bp-62dbac62-1feb-47a6-be53-bd8b10260913 13/09/2026, 11:08 View bp-9197029c-0719-4294-bc37-e7f320260913 13/09/2026, 11:08 View bp-941d7f54-5b2e-4783-83f2-66c330260913 13/09/2026, 11:08 View bp-00202476-8680-4295-8a76-a97db0260913 13/09/2026, 11:08 View bp-027dfa8e-f3e1-44e9-a405-1ae350260913 13/09/2026, 11:08 View bp-369f58c9-4456-4578-977e-49cfe0260913 13/09/2026, 11:08 View bp-78c25147-3a9c-4ad8-9210-eb0ca0260913 13/09/2026, 11:07 View bp-f1f4b2b3-0885-4259-8dd3-bfa700260913 13/09/2026, 11:07 View bp-72d20621-92ea-417a-b063-deba40260913 13/09/2026, 11:07 View bp-721a4c72-ab3c-4ea0-8428-72b6d0260913 13/09/2026, 11:07 View bp-ffb02689-cb96-48e2-ab89-1c7f10260913 13/09/2026, 11:07 View bp-407b7ac2-8d4c-404d-974a-96d790260912 13/09/2026, 0:37 View bp-9decd8ef-b380-4bfe-8264-6841b0260911 11/09/2026, 22:40 View bp-c9a8eae8-8723-48ba-aab0-48db10260908 08/09/2026, 22:57 View bp-e0ac525c-a6c7-4af5-abe8-0ab5e0260913 13/09/2026, 11:16 View bp-91be494d-2e41-42b7-9330-e49630260913

Hello everyone,

I would like to ask for clarification regarding the distribution of Firefox through third-party packaging methods.

As I understand it, Mozilla's trademarks and branding are protected, and in some cases official permission may be required to distribute Firefox under the Firefox name and branding.

Within the Ubuntu Touch community, there is a method called "Crackle" that can repackage existing applications and make them available as installable "Clickable" packages on the platform. One of the applications that has been repackaged in this way is Firefox.

However, this Firefox package is currently not available in the Ubuntu Touch software store because there is concern that distributing it may require explicit permission from Mozilla.

My question is therefore:

Does a project or community need Mozilla's permission to distribute a repackaged version of Firefox through a software store? If so, what would be the correct process for obtaining such permission? Alternatively, if the software is merely being repackaged to provide an installation method on another platform, without modifying Firefox itself, is additional permission still required?

We would appreciate any clarification regarding Mozilla's policies on redistribution, repackaging, and trademark usage in this context.

Thank you for your time and assistance.

This has been in the last month or so. It will freeze up and I can't break out of it. Last time it froze the whole computer and I had to power down and restart. There must be something that changed. And there must be some way for me to be able to quit when this happens. Last time it was on a video call with my 104 year old mother and it is very annoying. The whole thing froze and I had to restart the computer and when I got it back up, she was off. I need some way to break out so I don't have to do a complete restart. t.

Hello,

It seems that Firefox has lost the ability to clear cookies on exit without also clearing history. This affects the current version, 153, but I started observing it a few versions back, maybe around 148.

In Settings -> Privacy and Security, if I select "Clear cookies and site data every time you close Firefox", this automatically enables "Clear history when Firefox closes". If I unselect the latter, the former also becomes unselected.

I would like to clear site cookies and data whenever I close Firefox, but not browsing history. I'm sure this used to be possible in the past. Is it an intended change that this is no longer possible, or is it a mistake?

Thank you.

Not a question.

I needed to file a bug report so I went into settings to figure out what version I was on, only to be met with this useless view (see attached).

"About Firefox" contains no information whatsoever about Firefox. Who made this choice, and why? How is "let's show nothing at all on this page" a decision a product has made?

So when I start to type `dis` in the URL bar to bring up Discord (yes, I use the Web version), I've started to see `Manage AI Controls`. This makes no sense to me. I have all those set to block. And `dis` doesn't appear at all anywhere in that setting title. Yet when I start typing in `ai`, that setting doesn't come up.

Something is fishy here.

This is v154.0.1 on Debian/Testing, from Mozilla repository.

In my nightly broswer Codeberg opens once when I click to go to a repository the tab keeps loading and does not stop and can't accesss anything then. In Firefox I don't have that problem at all only in Nightly then in Nightly my Facebook emoji's does not show but again in Firefox it does.

FireFox Browser Crashing from Multiple Windows with Dual Monitors causing memory crashes in gnome.

google chrome used to have a brower extension called "The Great Suspender" to stop these crashes. If firefox can't figure this out I am not going to continue using firefox and go back to chrome.

Does FF have a maximum number of windows / tabs that can be open at one time? I use 12 workspaces each with multiple windows / tabs in them, roughly guessing ~100 windows and ~8-50 tabs per window

FF randomly hangs / crashes 1-3 times a day for me and has been for some time (over multiple revisions of FF; currently 157.0.1) requiring restarting FF

System: Large workstation, 128G memory, i9-7920x (12c / 24T) Linux, OpenSuSE Leap 15.6 FF source from FF repos, not OpenSuSE

Any settings I need to change to prevent the crashes?

Everytime I restart and open firefox and then try to access facebook, sometimes google, n=some news websites and probably other apps, I get a captcha, but it repeats no matter how many times I get it right.

I was advised to do this, but it's still happening: https://www.youtube.com/watch?v=6fX0_wiVKhw

But even that's stopped working.

I cannot access facebook and I need it for work (small org, no IT section to ask), and can't access some new sites.

I've gone to basic security settings, but that doesn't help.

What to do?

I.m an 81 year old man , and It is very difficult for me to use the computer, and now you make it more difficult for me with this new addition of Thunderbird that makes it more complicated for me,My question is: can I continue using Firefox with out Thunderbird ( that I don't like it ) ?

I'm using Firefox 152 (64 bit). When I try to enable the built in VPN, I get a message saying to check my internet connection, even though I am already connected to the internet. The VPN will not turn on.
