When I go to see a firefox bug such as the following, https://www.mozilla.org/en-US/security/advisories/mfsa2026-10/

There appears to be more details in https://bugzilla.mozilla.org/show_bug.cgi?id=2014390 located at the bottom. When I try to view the details it asks me to log in. I do not see any reason I should have to log in to view the issue as I only intend to view the bug. Why does it require a login ?

Hello. I have issue with Firefox. I am often opening firefox by command: firefox --no-remote -P <profil> --new-window "<web_site>" Usualy it works. But sometimes it is opening new window and my web_site is located in second tab. First tab (which is completelly unwated) start loading after clicking on it. It is a recently closed tab. I call this tab zombie-tab. It was finished and properly closed, however it rose from the dead. I tried to set in about:config browser.sessionstore lot of parameter to absolutelly forbid to save any information. However, there is still whole history in the list, sites are restorable and sometimes it appears these zombie-tabs. Restore from crash is also deactivated. I tried before to start the firefox without --no-remote parameter, but AI recommend me to add it there. It did not help. Since it is happening occasionally, I consider it as a bug. Some my settings: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0 browser.sessionstore.resume_from_crash = 0 browser.sessionstore.cleanup.forget_closed_after = 149 Version: 140.7.0esr (64-bita) OS: Debian GNU/Linux 12 (bookworm) How to prevent to create zombie-tabs?

I am using 147 ESR and when I go to permissions and block all cookies for the site plex.tv the cookies are not blocked. If I go to the URL field and select the lock, it shows "clear cookies and site data" which means the cookies have being accepted.

Why are the cookies accepted from the site when I have set cookies "blocked"

I am using 140 ESR version on linux with Cloudflare's DNS over HTTPS and with DOH active for some reason resolving a domain like d3oklwo3y1bx83.cloudfront.net will resolve to local host IP 127.0.0.1.

I am using firefox about:networking#dnslookuptool to test resolution of the domain d3oklwo3y1bx83.cloudfront.net Both with DOH on and off the resolution remains local host. I tried another browser on the same workstation and I was able to receive a resolution of 13.225.193.203 13.225.193.133 13.225.193.64 13.225.193.58 Why is firefox ESR not able to resolve that domain? What are causes ?

Is is firefox dnslookuptool results.

Since I upgraded from FF128-esr to FF140-esr I always get the "Firefox is being updated by another instance" This is really driving me crazy, as I checked / did / .... everything (and even more) I found on the internet related to that.

Nothing helps !

Creating and using a new default profile didn't help

Finally I ended up uninstalling FF completely (making sure no -zero- leftovers remained in ProgramFiles, AppData a.s.o.), and reinstalled FF140.7.0-esr freshly. After installation I started FF immediately with the created default profile (only existing one) --> SAME THING : "Firefox is being updated by another instance"

And this is really a FF140 thing, when I go back to FF128, on the same computer, same profiles, ...., the problem is gone.

I would like to know in detail what checks are really done by FF to decide to give that "Firefox is being updated by another instance"

I'm trying to use Booking.com to pay online for a holiday and Firefox keeps crashing as soon as I press confirm payment. Have tried several times using 2 different cards. What can I do?

Dear Mozilla Firefox.

I have tried so many times to reset my Mozilla Firefox account password to no avail, using my Account Recovery Key, which I stored in LibreOffice Draw on my computer. The so many times that I tried, the error that comes up is: "Invalid account recovery Key", no matter how many codes are sent for me to rest my password. Please, rectify the problem as to why a correctly stored 32 characters Account Recovery Key is not working for me to reset my password. Regards

A website I have accessed many times before now redirects me to an italian site. Is this because of the beta translation? I'd like to be able to go to the real site. mecaforpeace.org

this is nice feature

what if this translation could be run a standalone tool, command, or you call an api to translate something locally?

then we would be able to translate documents, mail, .. maybe just in html and plain text (with or without markup) format

one website is timing out, I started to have problem yesterday. I was able to load when I tethered with my iphone.

before that I tried

Closed all the application rebooting Mac tried on Safari

             Firefox
             Google chrome

with no success

Chrome says it's 504 error
