Diễn đàn hỗ trợ Firefox

Since update yesterday, new tab is empty. Whatever I do, open new tab, open new window, go to `about:newtab` manually, it does not load anything. The view is totally blank. I can navigate to other pages fine as it should though. Only New Tab view is broken. Diagnostic mode does not work. I don't have plugins that would affect New Tab anyways.

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

I have been using 1Password 7 to manage my login credentials. It includes a Firefox extension to fill in account names and passwords in login alerts and pages.

Firefox 147.0.1 (macOS aarch64) in January 2026 has broken 1Password 7's ability to fill in account names and passwords.

To reproduce: 1. Install 1Password 7 Version 7.9.11 (70911000) and its extension version 4.7.5.90 in Firefox 147.0.1 on macOS. 2. Visit a URL for which 1Password 7 has login credentials. 3. Click on the toolbar icon for 1Password 7. A 1Password 7 dialogue box pops down from the icon, containing the username and password for that URL. 4. Click the Autofill button in that dialogue box.

Observed behaviour: 1. Username and Password fields remain blank.

Expected behaviour: 1. Username and Password from 1Password 7 appear in the Username and Password fields.

For approximately the last three months, there was a partial failure similar to this. 1. 1Password 7 popdown dialogue moves from the toolbar icon to the Firefox tab for that URL. 2. Username and Password fields remain blank. 3. Workaround: click in the username field, then tab 2-4 times to further UI objects in the login credentials form. Then click the 1Password toolbar icon, then click the Autofill button in the popdown dialogue. Then, the Username and Password from 1Password 7 appear in the Username and Password fields.

The expected behaviour occurs for the same URLs in Safari.

Thus I suspect that Firefox has somehow changed its behaviour in the last few months to cause this regression. I have not changed the 1Password software versions in this time, because I am intentionally using a previous version of 1Password.

I am looking for a fix or workaround which works with my current 1Password software version. I am not interested in a solution which requires me to upgrade to the current version of 1Password. (The current version of 1Password imposes a feature which I am resisting.) I realise that this reduces the chance that I can persuade the Firefox team to find and correct this regression.

hello. my name is Andrew. im learning the language toki pona. great language! however, it does not currently have support in Unicode.

as a workaround to use this language online, people have been downloading a font called nasin nanpa, and adding it to firefox's font fallback system in the about:config settings, and using the fonts UCSUR characters, like these 󱥬, 󱥂​󱤴​󱤧​󱤑​󱦐󱤄󱤽󱤧󱤊󱥵󱦑.

[specifically, the font uses codepoints in the Private Use Area because the language's script is not yet in Unicode. ]

the changes are to these settings.

font.name-list.cursive.x-western font.name-list.monospace.x-western font.name-list.sans-serif.x-western font.name-list.serif.x-western

recently, this system has stopped working. this change breaks multiple websites, including many discord community's that used the font to talk online in toki pona!

it also presumably breaks other fallback scenarios. now im guessing that this has not been noticed as most fonts support every commonly used character, making this feature rather obscure. however i really would love this to be fixed, and so would the large toki pona community!

to see what i mean better, please see the below images. the last image shows a website that loads this font on it's own, showing what the others should look like.

Firefox 147.0.2 (64-bit) on my Lenovo Yoga 7 Windows 11 Home has been randomly malfunctioning when i use the hover over tabs with the mouse to show what is in the tab (small image) Sometimes it just fails for several hours, other times it works fine on its own later that same day.

I have tried to find this inside the browser several times with trying to find this browser-tabs-card-Preview-enabled inside about:config But it doesn't seem to exist in this version and apparently you can't add a new rule inside the browser to solve it.

Google AI solutions search is outdated or the wrong version. My computer and browser are up to date. How do i fix this ? I don't want to uninstall it, lose my logins and the bookmarks if i am unable to sync my files after trying to reinstall the browser only to find out it has failed.

Bought a new laptop and I had my old Dell laptop transfer all my data to my new HP. My email account went thru fine. But for some unknown reason, I couldn't get my Firefox browser transferred, and I NEED to get my saved passwords from the Firefox Master Password manager.

I think I made a big mistake after data was transferred and I started setting up the HP -- (feel like I got 'tricked' into using Microsoft Edge browser) and didn't know how to get Firefox browser so could get my passwords. So unfortunately, I ended up clicking Download Firefox browser and it was a brand new browser like I was a new first-time user as it was 'blank'....like I would have to start completely over. I have been a long-time Mozilla Firefox browser user. I have been desperately and frustratingly trying to retrieve my Original Firefox Browser that has ALL my info that was so handy and easy to use.

PLEASE EMAIL ME AT:: [edited email from community support forum] I do Not have a mobile phone Thanks for helping me retrieve my Mozilla Firefox Browser

Tried Old Firefox Data and I don't think it's there. I don't see it in about:profiles. I used it yesterday and windows seemed to refresh overnight. When I opened firefox this morning, an old profile came up (as it does sometimes). Usually when this happens, two profiles open and I just close the old one that I don't use. But this time only the old one opened. PLEASE HELP!!!

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

How to remove google search from the address bar on the right?????

I want to find my most visited websites in the address bar without any unnecessary actions!!!

My bookmarks disappeared and I do not know why.

I have tried to restore bookmarks following the directives obtained online. Somehow this has not been successful, and this remains a giant puzzle to me.

I can see the bookmarks in Library, but I have not been successful in figuring how to transfer that listing to the Bookmarks tab at the left-sided top of the frame of the browser.

Thank you.
