I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

Since the last update, the firefox taskbar icon is showing a strange shopping card icon? How can I remove it? I am not shopping with Firefox, I am using it as my web browser.

since the uptate to version 144.0.2 I have two problems. the first one is async streaming on platforms eg. youtube or netflix. The videos take a very long time to load. Even if a video has already preloaded and I skip to that area, the video takes an extremely long time to load again. The 2nd problem i have in livestreams eg. live-TV or twitch. The loading time is very long. It is so long that many livestreams are doesn't even able to start. So, it is no longer possible for me to watch livestreams on Firefox. what i've done to fix it: - I deactivated all Add-on's and deleted all browser Data - I made a new profile and deleted the old ones - I reinstalled Firefox

Nothing worked. so pls can you help me that I can use Firefox normally as usual? (sorry for my bad english, I'm from Germany)

When I go to (seemingly) any Elsevier site, the browser tab immediately closes with no error or explanation. An example is this site:

Firefox always auto-fills in the wrong phone number. But I can't find a setting that contains my phone number. How do I change my phone number that Firefox auto-fills?

Bonjour, je ne peux plus me connecter à ma boite mail hotmail.com depuis la version 144.0.2 (64bits) de Firefox Je suis avec Windows 11 famille 64 bits - 24H2 et 25H2 (j'ai essayé avec les 2 versions) avec un compte local. Je choisis de me connecter avec un mot de passe et après avoir validé le mot de passe, j'arrive sur une page qui me dit d'utiliser un autre appareil ou une autre méthode de connexion. Je joins les fenêtres de connexion étape par étape Avec Google Chrome (que je ne veux pas utiliser), je me connecte sans problème à ma boite mail avec les même étapes décrites ci-dessus. Pouvez-vous m'apporter une solution ? Merci, Marc T.

I'm having trouble opening urls in a private window from the command line on Windows 11.

Firefox version: 144.0.2

Starting a new private window works fine with "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window

But doing: "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window "https://www.google.com"

just opens the link in the last selected window if the last window selected is non private it just opens the link there instead of a new or existing private window

I have also tried with no success: "C:\Program Files\Mozilla Firefox\firefox.exe" -private "https://www.google.com"

I was resetting my password entered my email code recovery key it didn't ask for my authenticator got an error invalid token then after retrying it asked for email and authenticator but not the recovery key the account now says I have no key

Hi!

What goes wrong with a simple tracking request on the UPS website? Try my actual case with the following link: https://www.ups.com/track?tracknum=1ZA06B736800244687&loc=fi_FI&requester=QUIC%2F/ The response in Finnish is always: "Emme voi suorittaa seurantapyyntöäsi tällä hetkellä. Yritä myöhemmin uudelleen." A quick and dirty translation is: "We cannot execute your request right now. Try again later".

This is an everlasting problem. But try the exactly same link on Chrome or Edge, and it works fine.

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

• Disabled `Startup > Open Previous Windows and Tabs`
• Disabled all extensions
• Confirmed I do not have a `user.js` file
• Set `browser.sessionstore.resume_from_crash` to `false`
• Set `browser.sessionstore.restore_on_demand` to `false`
• Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
• Set `browser.sessionstore.max_resumed_crashes` to `0`
• Set `privacy.clearOnShutdown.openWindows` to `true`
• Set `browser.sessionstore.max_tabs_undo` to `0`
• Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

System: Fedora 42 (Workstation Edition) Running Firefox 144.0.2 on Gnome 48.6-1.fc42

I have a bookmark folder with 12 entries. In the bookmark manager, I see all 12 entries. when I select the bookmark folder from the toolbar, the drop down menu only lists four entries,

Hi a few weeks ago i had the problem that my firefox-stored-passwords are gone and there are files named logins.json.corrupt and logins.json-1.corrupt to -4 The in dir backup was also corrupt. File length 122 -123 kb all nulls. If i look at the dates first to last, they span two weeks were i didnt notice the problem. PC is always hibernated after work. Except for one which i imported just before from edge at the end of the two week span No problem: logins replaced by external backup as i found here at the forum.

But: How can Firefox produce multiple corrupt files without noticing me? (I have saved them for reference) In that two weeks span logins using firefox passwords obviously worked. (I dont remember the details)

Then some updates and reboots. No problem. But after work i do always hibernation

TODAY: PC didnt survive hibernation. logins and in-dir backup are corrupt again.

What about a) checking better if something is going wrong (obiously you do something because you rename the files for some reason) b) Noticing the user c) And how on earth this can go wrong in the first place.

Now for the obscure: Both times somebody has just before posted something against the greatest President of all time at Fux Nus using this pc. Backdoor possible?

Thanks

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

I have a pacer account and it instructed me to download Firefox than go to tools to add adobe so I can submit documents to the court online. Im getting confused can anyone help walk me through this process

Firefox updated to the latest version and it lost everything. All my saved passwords are gone, all my bookmarks, data, etc. It said I could sign in with my account and it would sync them and bring them all over, it didn't. I can't use the original profile because it says it's outdated, I don't even know if it's the correct profile anyway. What am I supposed to do?

Using firefox 144 on Kubuntu 24 LTS, on wayland, with Nvidia drivers.

I'm one of those guys with 500+ tabs. I also have a bunch of tabs open in specific containers and I recently spent a lot of time sorting most of my hundreds of tabs into a bunch of neat tab groups.

I'm not using any "sync between devices" functionnality

At some point, I open firefox like usual, and I noticed that it appears to be glitched. The rightmost tab (the last tab I had opened) seems to be working fine, but every other tab has no text, and I cannot switch to them. However, the colored line indicating that a tab is opened in a specific container still appears, it's just the tabs names that are missing. Also, firefox seems to generally not be responding, so I decide to close and reopen it.

Upon reopening, firefox restores my tabs, but I'm left with only the last tab I mentionned earlier. The "restore last session" button doesn't appear in "history". Neither "recently closed windows" nor "recently closed tabs" contain my 500+ tabs

I still have my extensions

I still have my bookmarks

I still have my base "new tab" setup, with my background image and my "pinned" websites (I don't know how it's called)

I still have my container "rules" (i.e, firefox still proposes to open specific domains with specific containers, even if I have lost old tabs that were opened in those containers)

I still have my "auto sign-ins" (i.e, I can still log into some websites without re-typing my password)

I have lost my tab groups

I'm used to losing my tabs. So I close firefox, and I go look in it's files.

The image firefox-mpris in the files still displays a youtube tab I was watching (yet this tab doesn't get restored)

I make a copy of sessionstore.jsonlz4 and sessionstore-backup, and try restoring from each backup by replacing sessionstore.jsonlz4 :

- the default sessionstore.jsonlz4 doesn't have my tabs of course

- previous.jsonlz4 has only the single last tab I mentionned earlier.

- recovery.jsonlz4 contains only 20-ish of some of the most recent tabs I had

- the "upgrade" files contains a bunch of tabs but it's from a few months ago so I'm missing the most recent stuff

Using this "scrounger" tool, I can look at what these files contain

https://www.jeffersonscher.com/ffu/scrounger.html

- sessionstore.jsonlz4 and previous.jsonlz4 both contain the single tab we talked about before (plus closed windows I don't care about)

- recovery.jsonlz4 contains exactly 25 recently opened tabs (plus closed windows I don't care about)

- upgrade.jsonlz4 contains 500+ tabs (with container ids, yay), but not the most recent ones of course (plus closed windows I don't care about)

From I saw online it looks like firefox only stores the last 25 tabs in these files, which are the last tabs I actually opened, even if more actually exist. What I really don't understand is : - Why does my upgrade.jsonlz4 file have more than 25 tabs then ? - Where are the other tabs supposed to be stored then ? the .jsonlz4 stores the last 25 tabs, yet firefox (usually) remembers all my 500+ tabs anyway, so where are they stored ?

Also, y'know, pls help me restore my stuff. Thanks.

My account has my primary email and it used to have my secondary email connected as well. I now want to create a new account with the secondary email so I can have another profile, so I deleted my secondary email from the manage accounts on my primary email. I ensured that this says it is removed on all devices and it is. But when I try to create a new account with that secondary email, I keep getting the error that I need to sign in my primary email and I am taken back to my profile with my primary email.

How can I fully detach my secondary email so that I can make a new account with it?

I have received 3 system alerts, all from Mozilla Firefox (I use Firefox as my default browser). 1) System is infected!---click on d45n9f8ko90s738b610.gsx-protect.co.in 2) ZEUS.2020 Trojan detected--with same directed site 3) System Alert!---with same directed site.

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Latest McAfee scan shows 45 entries deleted and 2 browsers reset

Hello, I am facing an issue while playing YouTube videos in Firefox. The videos are lagging and not playing smoothly, even though my internet connection is fine. Please help me fix this problem.
