Enhanced Tracking Protection is stopping me from accessing many websites which, on other browsers including Firefox for Android, have nothing wrong with them - UK Met Office, forums, webcomics, Patreon... In many places, it's stopping me from connecting to the website altogether, or even logging into desktop app services when I have to use a browser link to log in; the login process simply doesn't resolve. I've tried disabling and removing extensions, changing settings, refreshing the browser and clearing the startup cache, but nothing seems to help. I cannot work out what's wrong, and I cannot disable Enhanced Tracking Protection. I'm having to send this message via TOR browser, because on Firefox, the Mozilla Support site is reduced to just text and links, with no frames or images, and barely navigable. This also means I can't pull Troubleshooting data direct from my Firefox browser for this form, because the form page's display is also broken on Firefox; I may be able to provide troubleshooting data on request, but I will require step-by-step guidance.

I don't know what to do, and I need help.

I am switching from firefox to firefox-esr. Version 147.0.3 to 140.7.0esr, start firefox with --allow-downgrade which mostly works. What does not is the "Home default" page, it is blank and can not even be configured to what it was because the settings page is also blank, nothing below "choose what content ...".

I have done this on 4 machines now with same failure for the home page. settings. My previous workaround was new profile and import data so the setting page is therein ESR. This is a far harder than it should be there being no single export-import. I had to export import history with a third party plugin and cookies the only method [I found] was to copy the sqlite file. Others like password export-import are fragmented.

7/7/2026 Last night Firefox on my laptop performed an automatic update to the latest Firefox version. The new Firefox has a very bad setting in about;config .. this new Firefox can only show 1 tab ... it is opening up a new tab on top of the first tab, making it impossible to have more than 1 tab ..

This is going cause problems for thousands of Firefox users .. . how I fix this problem ... I tried setting the add tab settings into about;config to add a new tab to the right of the current tab, but my change made no difference ... how can I fix this problem ... does Firefox have a plan on how to fix for this problem for thousands of Firefox users.. this problem will impact thousands of Firefox users..

I have been using Firefox for many years and I was satisfied with this browser. For the last 2-3 weeks I have had a constant message that reads

I did everything, I deleted, I enabled cookies, cleared cache, but the next day the same message is repeated again. I'm tired of it because I have to retype my passwords every day and I'm close to permanently using MS Edge which serves me perfectly fine. Please give me the correct instructions on what to do to get Firefox to load my email normally again or I'm really going to quit Firefox forever.

Version 148 is very slow. When there are 5-10 downloads, other websites won't open. That's why I use version 140. And why are there so many files in the folder - ....profile\storage\permanent\chrome

Hello, the official mozilla page instructions for how to download Firefox for Linux (Debian 13) is wrong, it fails on Step 3 saying that the key verification is incorrect thus I have not tried the steps after 3.

I know Debian 13 comes with Firefox ESR but from my research this is packaged and maintained by Debian, I would prefer it if all my eggs were not in one basket and I actually had the real source maintainer updating my browser aka Mozilla.

I don't know what else to say, it is just incorrectly written or something, because Brave Browsers installation instructions are SOO much better and simpler, super easy works 10/10 times, and it's way fewer commands.

Please help, thanks!

1. This could be under-reported problem. People will have problems reporting this bug

2. Whenever I try to save anything (image, website, Ctrl+S, print website to file, Ctrl+P, screenshots, same problem) my Firefox tries to "Open" something instead. I see dialog window with header SAVE, but the final button is labeled "Open" and after clicking it usually nothing happens. A haven't been able to save anything since this update. Only system-wide screenshots work for me now.

I had to use another installation in order to attach screenshot here. In the problematic 149.0, after clicking "Browse..." and selecting file, nothing happens, and no upload, moreover button won't respond to clicking anymore. Then I force refresh, and this text within this form disappears, but attached image appears.

3. Yesterday I have updated my Firefox to 149.0, using official debian sources, mozilla-deb - 1.0 -

cat /etc/apt/sources.list.d/mozilla.list deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt/ mozilla main

4. I have Linux Debian, (old version, Stretch+backports, yes, I am moving things already to new hdd), maybe it's related: 4.9.0-19-amd64 #1 SMP Debian 4.9.320-2 (2022-06-30) x86_64 GNU/Linux )

In order to fill this form I am using separate installation 140.9.0esr (64-bit), you could warn Debian teams not to propagate this error.

5. I have checked Console and Debugger, but they seem website-related. This error happens on every single website. Tried already troubleshooting mode, same problem. Please help us.

Jakiś czas temu zauważyłem, że z Historii Ostatnio zamkniętych Kart znikają oglądane strony. Jestem już oburzony na to. Próbowałem wrócić do jakiś kart i nie było ich w historii. Funkcja ma być wycofana. Natychmiast. Jeśli będę chciał pozbyć się jakiejś strony to chcę sam to zrobić. Nie wy będziecie o tym decydować, ale użytkownik. Funkcja ma być wycofana. Natychmiast. Nie mam zamiaru z nikim o tym dyskutować, a tym bardziej z Sztucznym Idiotą.

je veux tout supprimer, que Firefox redemarre comme s'il n'avait jamais etait utiliser sur l'ordinateur. mot de passe, add-on, cookies, historique, ... plus rien !

ou est le bouton "reset" "delete all"

Please see attached. Netflix will not work. Never had a problem with any other videos so far using this amazing browser. Can we please get a possible update timeline for this - if possible at all?
