Recently, when I copy and paste an error message to the search box in Firefox and the first word contains a ':', such as when searching for this error message - "MESA-LOADER: failed to open dri: /usr/lib/x86_64-linux-gnu/gbm/dri_gbm.so: cannot open shared object file" - I get the "Open the mesa-loader link with System Handler?" prompt (see screenshot).

I used to be able to copy and paste such an error before into the search box and it would just work but now the browser defaults to thinking you are entering a URL. This could be because when I start typing in the search box, it immediately relocates what I'm typing to the address bar. Maybe this is the behaviour I need to disable? But how and why is it the default?

Help!

Hello. I am using Linux Mint 21.3 cinnamon and Firefox 144.0.2 When I use Google maps and the yellow small pointer (cartoon) to go on a specific street, the window come black when shifting to street view. My only extension is disabled, hardware acceleration unchecked, cache cleared and cookies cleared. I have made fresh install and nothing help. Troubleshooting mode allow street view to work fine but normal mode don't work. Google chrome work good. Chromium work good. And finally, Firefox work ok on my Linux mint LMDE 6.

Any idea where to go to solve this issue?

Thanks for your support

Hey, I am currently working on an application where I want to upload files to a server using mtls via a webapp. The upload goes to another url and server than the one where the webapp is served from. If I test the file uploading without mTLS, it succeeds, and with mTLS enabled it also works in chromium, but in Firefox I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <url> (Reason: CORS request did not succeed). Status code: (null)." on the `OPTIONS` request before the `PUT` is done. The client and the server both have a certificate from a custom CA, which I imported into firefox, along with the private key. Does someone know what the issue here might be? I am suspecting that there is some problem with firefox loading the user certificate on the preflight request?

<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">

   ...
   
   <Url type="application/opensearchdescription+xml" rel="self"
       template="https://example.com/opensearch.xml" />

</OpenSearchDescription>

Does Firefox still support automatically updating the opensearch XML description? MDN still mentions this feature: https://developer.mozilla.org/en-US/docs/Web/XML/Guides/OpenSearch#supporting_automatic_updates_for_opensearch_description

Also, in about:config, there used to be an "browser.search.update.interval" entry that specified the update interval. I can't find it anymore.

If this isn’t the right place to ask, could you point me in the right direction?

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

Tried to sign in to Firefox on a Linux laptop; searched for a password and finally found it under "a" for accounts;maybe my error. Tried to sync. bookmarks etc. from Android phone and it suggest two non existent menu options: Sign in and - i've forgotten; Sync between devices maybe; anyway nothing resembling either was in the menu so it is at least satisfying to know you can delete a browser with no concern that anything useful or even functional is to be missed.

Hi,

I am using mTLS to authenticate my computers reaching websites I manage. I imported client certificate on firefox and cloudflare is checking if the client is sending the right certificate. I am using Debian and Windows. On Debian (13), everything was working great until the version 140 ESR. I don't know why but the client certificate is not sent to cloudflare, sometime it is (when CTRL+F5) but no CSS is rendered. So I can't reach my websites. Firefox is still asking for the right certificate to send but that's all. This is weird because on the same version on Windows, with the same certificate, it is working. I tried newer version (144.0.2) on Debian but it is not working. The version I use at the moment is 128.14.0esr. Cloudflare is blocking the traffic because no certificate is sent. If I disable the rule, it is working.

Could someone help me? Feel free to ask for more details.

When I click on KPN TV+ I see a message: Firefox is installing missing components, try later. But Firefox is NOT providing missing components.. Or is the problem that KPN (and Ziggo IPTV) can NOT run on Linux???

I have a new Yoga Pro 7 and installed Ubuntu 24.04 on it. Cannot enable hw acceleration on it. Support page is given below. It says disabled by gfx. Also vainfo output is given below.

So if you go to My documentation page , go down to point 8 and try and copy the Systemd unit file from the browser to an editor, the line returns are not preserved and instead spaces are substituted. If I copy the text from a chrome browser into an editor, the new lines are preserved. I've copied the HTML source code below.

       [Unit]
       Description=Apache Tomcat 11.0 Web Application Container
       After=network.target
       

       [Service]
       Type=forking
       

       Environment="JAVA_HOME=/usr/lib/jvm/java-1.25.0-openjdk-amd64"
       Environment="CATALINA_PID=/opt/tomcat/Base/temp/tomcat.pid"
       Environment="CATALINA_HOME=/opt/tomcat/tom11/"
       Environment="CATALINA_BASE=/opt/tomcat/Base/"
       Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"
       Environment="JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom"
       ExecStart=/opt/tomcat/tom11/bin/startup.sh
       ExecStop=/opt/tomcat/tom11/bin/shutdown.sh
       User=tommy
       Group=tommy
       UMask=0007
       RestartSec=10
       Restart=always
       [Install]
       WantedBy=multi-user.target
     

So the code is rendering correctly in the browser, but is being incorrectly copied by Firefox. Note if you copy the above from this forum across to an editor the new lines are preserved, but if you copy it from the website they are not.

Hello. I have this problem for almost a year now. There are websites where my Firefox crashes constantly and I can't use it at all for browsing them. All such websites are mostly online stores where you can buy something by putting it into cart and then proceeding to order page. I can't even scroll through product pages, it crashes in second after opening the webpage. For example, ozon.ru

This happens in Troubleshoot Mode too.

Firefox 128.8.0esr (64-bit) Debian 11 (bullseye) Xfce 4.16
