Previous to version 151.0.1, when I pressed ctrl-L, Firefox focused the URL bar and I was able to edit the URL. Now, on 151.0.1, pressing ctrl-L clears the URL and a dropdown for the search engine appears in the left of the URL bar (see attached screenshot). I have verified this on a new, blank profile. Is there a way to restore the old behavior?

After connecting and signing in to Mozilla Connect, it seems impossible to actually log out. There is a log out option in the dropdown menu, but it doesn't work. After "logging out", when going back to the site one is automatically logged back in. This is true even after clearing all mozilla.org cookies, and closing the browser. If a different browser is used, first time access to the Mozilla Connect site requires username/email and password, but after the first access, the alternate browser is also perpetually logged in.

1. What mechanism is being used to identify me as the user after cookies are cleared ?

2. How does this fit in with Mozilla's claims to respecting user privacy ?

3. How do a log out of the Mozilla Connect site ?

bold textI have finally installed Debian 13, Trixie, into my computer. However, I don't seem to have attached to the Debian Mirror. How can I do that?

Trying to not just edit a PDF in Firefox on Linux but actually edit the document using its Dynamic-XFA format elements of that PDF. XFA is an Adobe proprietary format that they depreciated several years ago but it still works in Adobe Acrobat Free. (I use a Windows guest VM for this as a workaround for now but I'd rather not since it takes extra resources and time). Elements can be filled in FF and some menu drop downs work in FF but other dynamic XFA element buttons don't respond like the one I attached.

In Acrobat the "X" and "Add Contact" buttons will add or remove some elements to the document.

Can this be done in FF desktop?

Version 151.0.1 (64 bit) on desktop PC.

In about:config I know there are a lot of options to modify under the search term "pdfjs" but I don't know what element would allow this to possibly work if its supported.

I wish I had other better options but government documents are what they are.

I'm on Debian 13 stable with firefox nightly (tarball) downloaded from the firefox website with firefox running on wayland. I don't recall the exact time / build that this issue happened, but it has been persistent for over a week or two already.

The issue I am seeing is where secondary menus or popups do not scale properly in firefox. This includes Popups for extensions, right click menus, or even link previews (long click left mouse btn).

<See screenshots>

Things I tried with no luck:

• Restarting my computer
• Restarting firefox / Updating firefox from the firefox website (https://www.firefox.com/en-US/channel/desktop/)
• Changing my display scale (100%) to (90%)
• Changing firefox display scale from (130%) to (100%)
• Refreshing firefox through the settings (aka clearing extensions and all the other stuff)
• Switching to X11 and back to Wayland... X11 worked fine, but back to Wayland just got things borked again
• Updating all system packages on Debian (nothing much except for security updates on debian stable)

Now the questions I have:

1. Is there a way to fix this issue? 2. Where could I file a bug for this issue? 3. Are there other people with this same issue?

i cant get in my you-tube for watch full movies and tell me about DRM and then that Firefox is installing components need to play the audio or video on this page.i need help to fix this

I have a home server 192.168.0.240 in my local network. Firefox does not let me in to my own pages. On the address line appears text "Not secure",

I have found no way to get in. I have there REALLY IMPORTANT TOOLS AND MATERIAL and I need it AS SOON AS POSSIBLE !!!!

This is really stupid. I have used these pages until this weekend. I have had this problem many years, but always found some way to make it work. I am NOT going to buy a certificate to every server I have home. it costs $$$$.

With Mozilla Firefox for Linux Mint 150.0 after logging into Chase Bank , when trying to pay off my credit card, I get a message: "It looks like this part of our site is not working right now". However the site works perfectly with Chrome, thus the problem must be with Firefox. I have cleared the Chase cookies and still getting the same result.

Need an update for the update. My Mozilla settings say my operating system (Ubuntu 22.04) handles the updates, and it's a deadend. I can only use my browser for one minute before it freezes.

Hello, I have a protonmail account connected to my firefox account. The protonmail account was inactive for a while. Now I am trying to connect a new device to my firefox, but the E-Mails never reach me. I have added accounts@firefox.com as a contact and whitelisted it from being seen as spam. Is there any way to solve this without making a new account?

I have a Raspberry Pi 4b with a 64bit 4 core Arm CPU and 8GB ram. It is currently using Debian Trixie with the Xfce4 desktop.

I installed Firefox, and went through the setup. I made sure that in settings -> general the "Open links in tabs instead of new windows" is checked. I also set the about:config "browser.search.openintab" is set to true. My default search engine is DuckDuckGo.

Firefox will not open any search in a new tab. It opens them in the search results tab only. I have an x86-64 notebook and an x86-64 desktop running Xubuntu that are using the same settings, and they function properly.

Am I missing something? Is this a peculiarity to the arm version of Firefox? Is there another setting specific the Raspberry Pi or arm Firefox that I have to change?

Cheers!

I have [[created a backup file|https://support.mozilla.org/en-US/kb/firefox-backup#w_protect-your-sensitive-data-with-a-password]] today with the latest available Firefox and switched to a new OS. Sadly, the backup file somehow seems to have gotten damaged, even if Firefox still recognizes when I'm inputting the wrong password. On Ubuntu, where I originally created the backup and where I tested it again after things weren't working out, Firefox tells me that there is an issue with the file and that I should try a different one (which I don't have). On CachyOS, which I'm currently testing out, restoring the backup never finishes and Firefox doesn't exit cleanly. In hindsight I obviously should 1) have tested the backup immediately, 2) not have wiped my laptop prematurely, and 3) have backed up the folders manually, but I haven't. Now the question: is there some way to extract the account details from the .html file? I don't care much about the rest, but restoring the accounts in some other fashion is gonna be a lot of work.

I am okay with just being sent the download for win 10 or 11 because I'm not sure why its even giving me such a out dated version. (side note I do want to mention that it is amazing Firefox has the option and goal to let you install a different operating system instead of locking you out to just a Linux version and i do want to say i don't use Firefox as my main browser but a back up from now on because of the accessibility)

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.
