Firefox Community Forum

I am unable to access about:addons on firefox, and I don't what I should do to unblock. I blocked about:addons myself, but I don't remember exactly how I did that, and now I am locked out. Could you be able to help me out with this?

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

       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

One of the recent crash reports: bp-a94b8ff4-9b5d-4909-8948-d6e120251030

Whenever I use Firefox to open sites like Google and Yahoo they appear with foreign languages like Spanish and Indonesian. Sometimes it asks me if I want translation. My default location on Firefox (weather) is in Argentina. When I open the default location to my settings, they show English (US) as the default language. I also can't change my default location to Los Angeles, California, USA.

I went to Wirercutter from the NY Times, tried to search and got the result "HTTP header is larger than 10240 bytes." I performed the same action with Chrome on the same machine with no problems. I am on Firefox 140.4.0.esr running on a Slackware64/15 machine.

These features are, at best, unwanted by me, forever. Is there any way to ensure they remain disabled and no future features that use it get auto-enabled?

Thanks!

While I do find the AI Chat option in the sidebar useful, I don't really like that, since I've opened it, it will always be open when I launch a new window.

Is there a way for the side-bar to remember it's state, so that if I close it, before closing the browser, that it won't open when I launch a new window?

If not a state recall, how about an explicit setting? It's a bit irritating to have to close the sidebar every time I want launch firefox.

The floating translation button stopped working on my laptop in only one of the windows on the website. The button appears in other windows on the same page. Everything works fine in another browser on the same laptop. I noticed this problem after updating the Mozilla browser. I checked all the settings and exceptions. Please help.
