Firefox Community Forum

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

when i open firefox (including opening a new tab) my CPU peaks at 100% on all cores for a few seconds. this is without any pages loading and without many heavy extensions (all i have is malwarebytes and dashlane)

My firefox browser crashed last week. An IT expert uninstalled it and re-installed it and it is working ok. But when I try to buy goods online my stored card is being rejected but I don't know why. Can you help please?

After recent update, I can not browse any addons. The site https://addons.mozilla.org does not open, shows the connection timed out. I uninstalled and reinstalled firefox deleteting all firefox related files. The problem still persists. Other than this all the using browsing I do are all working fine. Just this extensions I cannot browse. When I click the extension icon by default it shows some extensions, I can Install them. The problem is I can not browse them. Even the recomendation tab is also empty.

PS: I am using firefox on manjaro linux.

Hello, after a power cut I lost all my bookmarks. When I try "Manage Bookmarks -> Import and Backup -> Restore -> Choose File..." nothing happens.

In the folder ".mozilla/firefox/6924v31j.default-1728390329118/bookmarkbackups" there are several backup files, but the newest has the date Jun 25, though the name suggests it's from Jul 2: -rw-r--r-- 23850 Jun 25 13:07 'bookmarks-2025-07-02_184_mg1znof1NbBiyJ14ZcO9SluvTvLZI-rxPSm20YZUJww=.jsonlz4'

In the directory ".mozilla/firefox/6924v31j.default-1728390329118" there is also places.sqlite from Jul 4 11:59 (that was the moment when the power was cut).

How can I restore my bookmarks?

I have Firefox on 4 separate devices (Windows 10, Windows 11, Linux Ubuntu derivative x 2).

For the last 2 weeks, every time I open Firefox, the recommended stories are active. I go into settings, turn off the setting and it behaves correctly for that session. However, when I open Firefox on a different device, or the next time, recommended stories are showing once again. I like and want a clean, minimalist interface, and expect Firefox to honour my settings.

Thank you.

My mail checker extension isn't working right in Firefox. Extension Link I was able to find an error using Developer Options but I don't know if the error is even related to the extension or if it is even useful. If anyone would help me, I would be very grateful.

I am trying to load a page I load everyday and am receiving the following error message:

Secure Connection Failed

An error occurred during a connection to app.seg-social.pt. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Can someone help me please. Thank you.

HI Mozilla, I have recently purchased a new laptop and am setting up my desktop icons. I have the latest version of Firefox on both the old one and this one. also Windows 11

On the old computer (which I set up 18 months ago and still works) the desktop icons show the website logo. The correct logo appears for any newly opened websites for which I set a desktop icon.

On this computer all website desktop icons show the Firefox logo and not the website logo. This happens whether I drag the address or the lock symbol. I can change the icon using the inbuilt menu, but this is tedious and I would prefer them be the correct ones.

The correct logo appears if I right click on an app in the start list and drag it to the desktop.

Consequently I think the above is a Firefox problem.

I have been using Firefox for some years very successfully.

I do not like the function of opening last page I was on when restarting firefox. I use a program to help eliminate my browsing history. foxfire brings up last page I visited and ruins the work. I have un-checked open last page but it does not help. The program cannot get to something in firefox to erase my history. I like firefox but will discontinue use If I cannot resolve this issue thank you, I am very frustrated.

I get notifications from Firefox browser saying that I have messages, but if I click on the notification it just opens the browser and doesn't take me to the message that I clicked on. I can't seem to figure out where said messages are hiding. It's a little frustrating. Can you please tell me where these messages are at? It will be greatly appreciated. I took a screenshot of the Firefox version I'm running. I hope that helps.

I want to set firefox to use noai.duckduckgo as my default search engine so I can continue to type queries in the address bar. How can i change the settings to include noai.ddg as a default option?
