Unsure if it really matter, for now, but my firefox account, when I go to edit bits and pieces, it gets my Firefox version correct, but gets my MacOs version wrong. I'm on 12.76 (Monterey), but Firefox is showing me as 10. Is this normal or anything that might matter?

And a screenshot below just for those, like me who, prefer a book for it's pictures

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

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

hallo, I use "Qwart" Browser as Internetbrowser in Firefox extension. But I can't see an Qwart-icon on menue-strip. I receive a message "Quart-Search engine can't read and change data from this Webside" Extention best regards klosterberger

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.

Reader view doesn't work on many Lifehacker pages/articles. Can something be done to make it work on those pages? Here's an example:

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"

Hi, after latest update just now, the browsers uses up to 45gb of ram within a few minutes! Not sure what it is, I am on MACOS Sequia Version 15.6.1 (24G90) macbook pro M1

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?

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.

For years I have clicked on the clear history, clear data and manage data on the settings page in privacy and security--directly after leaving every website, just to be sure...now nothing is happening when I click on them. FF is up to date and nothing is different (that I know of).

Please help. Thank you.

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

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)

Problem: Cannot clear history from Firefix Started with Menu and clear recent history. Looked everyplace there was information about history. Tried removing individual entries. Ran Malwarebytes. Dell XPS 8960 with Windows 11 less than one year old. No response with any steps I take. Also, there are no error messages. I am unable to clear history no matter which tools I use. No error messages. All the suggestions I tried had no effect. Used Troubleshoot Mode in Firefox.

Oddly, I tried my older Dell Inspiron 3650, with Windows 10, and clear history works like it should. 

Used Troubleshoot Mode in Firefox. So far, all the advice goes down the same path; history, clean recent history, manage history, etc.. Tried refreshing and today I deleted Firefox app and reloaded. No improvement. Results same with Verify Integrity > Task: checkIntegrity - Unable to fix corruption, places.sqlite will be replaced on next startup > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task. Please help... Rangercarol

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.

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?
