Firefox Community Forum

Hi I have been using firefox on linux for a while without updating it. We are artsellers and I used to be able to log in and out of an artplatform without any problems. It's now been a few weeks since logging out is not possible any more on this platform which means that I am constantly logged in which I really do not want. The menu does not work anymore on this side whereas it works with other browers. I already contacted the platform. They cannot do anything about it themselves and asked me to contact your team. Please help. Thank you Best regards from Germany C. Marsac

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

I'm setting up a user on a new computer. I've exported her bookmarks from her old computer. On the new computer I go to Bookmarks > Manage Bookmarks > (select bookmarks toolbar) > Import and Backup > Import bookmarks from HTML. I browse to my folder containing the bookmarks.html file, Open it, and nothing.

I've tried all the suggestions I can find. Places Database Verify Integrity gives me: > Task: checkIntegrity + The places.sqlite database is sane + The favicons.sqlite database is sane > Task: checkCoherence + The database is coherent etc. Opening the bookmarks.html file shows a list of bookmarks. That file is not empty.

This shouldn't be this hard. How do I accomplish this?

Last few days I've been getting this popup:

Attention!!! Click to turn on the antivirus

or

Attention!!! Click to scan the device

obviously some phishing or something. How can I get rid of it?

Hello, American website and the German website German website fail to load the last 20%. This causes important top row graphics like logins and accounts not showing. Firefox private window loads the AliExpress website 100%.

I'm unable to login to account.apple.com on my laptop which is running Ubuntu 24.04.3 LTS.

I've launched Firefox using the `-p` option, created a new profile and then navigated to https://account.apple.com/sign-in and tried to login. I've attached a screenshot of the error message.

I had tried multiple things on my default profile, even troubleshoot mode, but I couldn't get it. I even tried useragent switcher to no avail.

I can login to the site using Chromium.

What else can I try?

Hello Firefox team,

I downloaded firefox-142.0.tar.xz and copied the necessary files to the appropriate directories. Unfortunately, I am missing the 24x24 and 256x256 icons. Could you please add these resources?

I would be very grateful if you could help me with this.

Best regards Chris

I actively use keywords to search from the address bar, mainly g for google, gs for google scholar and w for wikipedia. Until a recent update (until last week, I think), pressing ctrl + L to go to the address bar would select all the text in the address bar, including the keyword, such that if I had made a google search by typing g and some query, I could immediately do a wikipedia search by typing w and some query.

Now, with an updated firefox (141.0.3, on xubuntu 24.04), the search engine from the previous search remains when I press ctrl + L, so I have to type backspace(s) to remove the search engine keyword, before typing a new keyword.

Is it possible to get the old behaviour back?

On Linux, clicking the X in the upper right hand corner of the Firefox display, or entering CTRL-W kills Firefox with no warning. It would be nice if there was an alert that came up asking "Are you sure if you want to kill Firefox?". Or at least add an option for this in Settings.

I have never managed to get Firefox Sync to work on my devices, I don't know why. I don't get an error message saying it failed or why it failed. I run Firefox on desktop (Linux) and Android, both always updated to the latest version.

My use case is simple, I just want my mobile Firefox to have all the bookmarks I have on desktop already.

On Android, when I go to my account settings it says "Las synced: never". Clicking the "Sync now" button does absolutely nothing.

On Desktop I go to Settings - Sync, press the Sync button. It appears to work, though no feedback is ever provided.

When I go to about:sync-log, on desktop, finally an error is shown. It seems to attempt to connect to https://sync-765-us-west-2.sync.services.mozilla.com/1.5/207352084/info/collections and fails. Manually going to the URL also fails on both desktop and mobile. Entire log below

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

Recently I had un/reinstalled my firefox via snap and apt from linux. I'm signed into my account yet locally I'm not getting data to sync across devices. Any idea?

This issue has arisen on Firefox for Linux Mint (my current version is 123.0 (64bit)). I like Firefox, and I like its bookmarks toolbar, and have used it for many years, but there seems to be a new bug introduced today:- The bookmarks toolbar is present and correct when I start Firefox, but now it disappears as soon as I select any bookmark, or if I enter any web address or if I open a new tab. The [View >Toolbars > Bookmarks Toolbar > Alway Show] option is already selected, but the toolbar is no longer visible. If I click on it again, the bookmarks toolbar reappears (or I can restart Firefox, and this will also restore the toolbar). But the toolbar now disappears as soon as I use the browser in any way, and so is currently not really of practical use, as it needs constant restoring. Hope you can help resolve this. Many thanks in advance

What settings do I need to get Street View to return the street view rather than a black screen in all 4 of my Ubuntu browsers, when it used to work fine but now is trash ?

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

Whenever i search something on google, firefox desktop (all fine on android) is failing to display the ai(gemini) answer no matter what questions i ask.

Same happens in the "AI Mode" option that is available in google's recent update.

And, I,m logged in.

This started since a week, everything was working fine before that.

Adding the images below.

hello, I've been trying to follow Firefox's official guide in the docs and ready 3rd party articles in order to enable payment method auto-fill in Firefox. however, this section seems to be missing from my settings page.

under Privacy and Security, I cannot find anything to do with saved payment methods or the checkbox to enable payment method auto-fill.

how can I resolve it?
