I'm having the exact same problem as what was originally mentioned in this post from 4 years ago.

The "chosen solution" was to exit firefox through the hamburger menu, which I find to be absolutely ridiculous. You mean to tell me that even though I close EVERY OTHER APPLICATION either using the "X" close button or a custom keybinding that I've set for my own personal convenience, firefox requires me to exit through a menu every time in order to make it behave the way I've told it to? No. Absolutely not. If I tell firefox that I don't want it to save my last session, that means I DON'T WANT IT TO SAVE MY LAST SESSION. If I've deselected the "open previous windows and tabs" option in the settings, then under no circumstances should it be trying to open my previous windows and tabs.

I've tried the suggestion to change the value of browser.sessionstore.max_resumed_crashes from 1 to 0. The problem persists, I assume because firefox considers being closed using the close button to be a "crash", which is interesting.

I the other suggestion further down in the thread was to set browser.sessionstore.resume_from_crash from true to false, which will prevent firefox from recovering a session from a crash. This is hardly an appropriate solution. I want firefox to resume my last session if there is a legitimate (key word LEGITIMATE) crash, because my session was closed against my will due to something that went wrong. Being able to recover my last session in such a situation is nice. I do not, however, want firefox to resume my last session when I explicitly closed the last session myself, which would be the difference between a crash recovery and restoring a previous session. If no crash occurred, I don't need a crash recovery, and aside from a crash, I don't want my previous session to be restored.

Are there any solutions to this at all? Because this is one of the biggest reasons why I stopped using firefox. I want to come back to firefox because everything else that's worth using is either dog shit, or Chromium-based (i.e. also dog shit). However, I find this broken feature to be somewhat of a security issue. If a bad actor somehow gains access to my system, I don't want him to be able to open firefox and have access to my last browser session because I closed firefox using a keyboard shortcut instead of closing it through a goddamned menu.

Hi,

Today, Firefox appeared to freeze as I was trying to sign into my Hotmail account and then crashed. Subsequent attempts to restart Firefox result in crashes. Usually immediately, sometimes after about a minute.

I have tried "refreshing" Firefox, running in troubleshooting mode, and uninstalling/reinstalling. I also performed the memory test suggested and had no errors.

There are no crash reports in the "Crash Reports" folder.

I have Windows 10 Home, Version 22H2, Build 19045.3693 (not sure if this is helpful or not)

Hi. I've used Firefox as my main web browser on desktop computers for over a year now, and it's so far been the best web browser I've used.... except for one issue when it comes to major updates to the app.

I have Firefox set to open up on the tab/site I was using before I end a session and close the app. Whenever there is a new major version release, the update gets installed the next time the browser is launched before showing the browser window. But, when the window opens back up, I'm not sent back to the site/tab I was previously using. A new tab automatically opens up to a Mozilla page saying that Firefox has updated, along with a large promotion for another Mozilla service.

I then need to manually close this new tab, and find the tab I was previously using during the last session before the auto-update. This is mildly irritating since it takes some control away over how I want Firefox to start up, and the new update tabs seem to just be used as a way to promote other Mozilla products seeing how the actual "Firefox has updated" text is very small.

Is there a way to turn off these automatic new tabs after every major auto-update? Or if there isn't, could an option to change the way Firefox notifies about updates be added in a future version, such as using the OS' notification option instead of opening a new tab?

Currently running the latest version of Firefox on an iMac, with Mac OS Sonoma.

I have been playing gin rummy plus on my windows 10 pc in my firefox browser with no problem until a few minutes ago when I tried to sign in to the game again. I got this message: Your browser does not support WebGL. The game works fine on my laptop using the same browser. Can anyone tell me how to fix this problem?

As of yesterday when I was running v119.0 I was able to screen capture streaming content from Hulu/Netflix etc, this morning after upgrading to v120.0 overnight, that capability is now lost. Video and still captures are just a black screen. Please fix!

I am in Europe. My Bank is in the U.S. I can no longer log on and access my account through this Mozilla Browser.

I continually receive this message:\Secure Connection Failed

"An error occurred during a connection to click-notification.capitalone.com.

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."

This is my ticket (116230) from my initial request.

What can I do?

Please help me restore my bookmarks and history - the update seems to have wiped everything clean. PLUS I have multiple Firefox icons appearing in my dock. MacBook Pro.

Release notes for Firefox v120.0 https://www.mozilla.org/en-US/firefox/120.0/releasenotes/

Among these release notes, "Firefox’s private windows and ETP-Strict privacy configuration now enhance the Canvas APIs with Fingerprinting Protection, thereby continuing to protect our users’ online privacy." How good or bad is the feature? There's the canvas blocker extension which might now be obsolete, then again without details this is impossible to anser. How exactly does the Canvas API enhance Fingerprinting Protection with this new update? The release notes don't explain that, where do i find details? Firefox should use this for all windows not only private ones.

Among the relase notes, "Firefox is rolling-out Cookie Banner Blocker by default in private windows for users in Germany during the coming weeks. Firefox will now auto-refuse cookies and dismiss annoying cookie banners for supported sites." I'm not german but would still like to use this feature as the cookie agreement popups are extremely annoying and time intensive to dismiss. Apparently in about:config "cookiebanners.service.mode" is the precise setting name. Does it have to be set to "1" to be active? This setting seemingly has the potential to replace extensions such as "Cookie AutoDelete" or uBlockOrigins Filterlists/Easylist cookie notices. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox has enabled URL Tracking Protection by default in private windows for all users in Germany. Firefox will remove non-essential URL query parameters that are often used to track users across the web." I don't get why this would only be active in private windows and germany. Firefox should use this for all windows not only private ones.

Among the release notes: "Firefox now imports TLS trust anchors (e.g., certificates) from the operating system root store. This will be enabled by default on Windows, macOS, and Android, and if needed, can be turned off in settings (Preferences → Privacy & Security → Certificates)." I've no idea what to think about this, is it a good or bad change and why? Don't try to fool me here, i want honest ansers no BS... is there potential for abuse? If Firefox uses CA's from the OS then what happens to firefox internal CA's, remain unchanged?

Among the release notes: "Firefox supports a new “Copy Link Without Site Tracking” feature in the context menu which ensures that copied links no longer contain tracking information." While this is a welcome change, i'd be much much more useful to replace “Copy Link Without Site Tracking” with “Open Link Without Site Tracking”... Otherwise there's the needless waste of time manually open a new tab and paste the link... This completely lacks any logic if you ask me, why didn't mozilla make it as i suggest above in the first place? Why the manually klick klick waste of time?

Lastly a question unrelated to this update, when RFP is enabled and the browser-screen-size is spoofed, if i go into fullscreenmode by accident, will this expose my true resolution or not?

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

I have Firefox as my browser on my laptop. Today I have been getting numerous pop-up messages from McAfee (which I do not have- I use a different web defense app) saying I need to renew my subscription or virus detected. Nothing I do gets rid of these pop-ups, which keep coming back (see example below) . How can I stop this from occurring? HELP!!

Trying to access my Tesco account but a page saying 'Access Denied on this server' appears. Can you rectify this? I urgently need to login to my Tesco Account.

PS. I have tried to solve the problem for 2 days but no success!

Up until today video on youtube played fine. Today I can hear audio, but the scree is just green. Trying to fix myself, I read change preferences in Fire Fox. But I can't figure it out. Bitchute and Rumble play fine. I reset my desktop by turning it off. Same with closing down my browser. No help there.

When watching videos on YouTube or Amazon Prime, Firefox will eventually stop recognizing keyboard and mouse input in all windows and tabs. This can happen after just a few minutes of video or after hours. It affects nearly all input: typing or clicking in webpages, the toolbar, the address bar, etc., though I can click the 'x' button to close tabs. When I close the final window, a dialogue will appear stating that Firefox is non-responsive and allowing me to kill the process. This seems unusual, because the OS's system monitor indicates there is plenty of unused and available RAM and CPU resources. Firefox behaves normally after restarting.

OS: Xubuntu 22.04 Firefox version: 120.0 (though previous versions have been affected for the last few months)

Poco F2 Pro is hard crashing requiring device reboot, starting maybe a week ago, and has happened three times. I don't know if it's hardware related but I've not seen the behaviour in other apps. I'm not using beta version.

Hi - I just reset my PC and trying to restore Firefox. I saved the default release folder (qejikze4.default-release-1669319412153) which contains the latest bookmarks in the "bookmarkbackups" folder. I tried to just replace the bookmark file in the new install (how I previously transfered them), but I can't find the files in the latest V.120 version. Any suggestions on how I can do it?

Thanks

Peter
