Is there a Firefox setting that automatically clears cookies? When I turned my computer on, it had been cleared of cookies since the last time I had it on a few hours ago, but I didn't do it. No one else here to use the computer but me. I don't want cookies cleared automatically. How do I change it back to manual? I use Firefox Browser 120.0

thank you

I am using the latest version of Firefox on Linux Mint. I've had some flash on opening issues that I've been unable to permanently prevent. Suddenly my adblock software is not working. I tried uninstalling, reinstalling, different adblocks-no improvement. No extension software is showing on my toolbar and selecting the extensions software just brings up a suggested extensions.

Starting on 12/1/23 Firefox browser on Windows PC is Not Responding while loading up bookmarks toolbar. Switching to "Never Show" is only way to load the browser. Trying to open or manage bookmarks freezes up the FF browser again.

My regular profile has deleted all saved history, tabs, bookmarks, etc. This happened before and seems related to having private browings open. and to an update in progress or recent.

Opend a private window. Then noticed regular FF wasn't opened. I opened the usual profile and all saved info is gone. Also, my stuff to be synced is way out of date so can't restore from there (I always had sync up to date). My "backup" can't be opened to restore.

Where do I find yesrterday's info? How do I restore my session, bookmarks, etc?

Last time, I tried to follow directions I found soemwhere but the instruction werent clear at all and had to restore from a disk image.

Why is there stsill the private window deleting regular window?

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 everyone,

My computer crashed while updating from Windows 10 to Windows 11. Unfortunately, I had someone look at it and he formatted my hard drive and only did a partial backup of files. I thought my Mozilla Firefox account was syncing, but it seems like it did not happen in a while. Does anyone know if there's any hope in recovering the lost tabs and bookmarks? Any help would be appreciated. Thanks,

Kenan

This issue started with a (frustrating) set of steps following a page which wasn't displayed (https://www.ziggogo.tv/) - the screen remained black. Refresh solved it but the reinstalled plugins didn't show an icon and did not work at all. I de-installed Firefox, installed some old version from an update, installed all plugins and then updated to the latest version. Now finally everything seems to work- except that the 2nd and next windows show at a quarter of the size compared to the first whchi show correctly. I've tried everything I could think of with xulstore.json in the correct ..\AppData\Roaming\Mozilla\Firefox\Profiles\ subdirectory but nothing helps. I deleted it (which requires you to re-check that you want a menu bar),when I though for a moment it worked, made it read only (which means Firefox makes a .tmp version of it), manually changed the content (e.g. to "main-window":{"screenX":"4","screenY":"4","width":"3840","height":"2048","sizemode":"maximized"}}} matching my 4K monitor but nothing helps. And no, Ctrl click the Close button doesn't help either.

I suspect that it is a (maybe reintroduced) bug in a later build. I don't update often and I haven't seen this issue before.

Anything I can do which I haven't tried?

Is there a way for me to make custom JavaScript code to add things, like a built-in music player, to Firefox? I think it would be pretty neat if users could code their own things to add to Firefox.

Animation triggers my migraines.

Man websites use transition and animation timing functions such as "ease in-out" to animate the interface. I try to block this. Among other tools I use userContent,css, including the following:

• {animation-timing-function: step-start !important}
• {transition-timing-function: step-start !important}

This works to de-animate regular css elements, but not ::before and ::after pseudo-elements.

The current css standards do not apply user css to pseudo-elements. I've written to the WCAG about the issue.

https://bugzilla.mozilla.org/show_bug.cgi?id=1865572

https://github.com/w3c/wcag3/issues/40

But I really really need some way to de-animate these, because they trigger my migraines. Aside from css fixes, I often reduce the frame rate in about:config, but can't always do that, disable smooth scrolling, disable animated gifs and animated pngs, disable autoplay, block various non-scrolling elements using either css or uBlock Origin, etc.

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

I don't remember with which version of Firefox for Linux this issue started; but I cannot play multiple videos at once. If I open two tabs with video sources one of the videos will automatically pause if I start watching the second one.

I have tried disabling my add-ons but the issue persists and I don't think there should be any reason for any of them interfering with videos.

Currently running Firefox 120.0 (64-bit - Arch Linux)

I use the read aloud function of Firefox regularly and it keeps skipping important parts of the texts! Attached is a screencap of the article I was reading today, the most recent example of this (https://www.analystnews.org/posts/to-understand-the-israel-palestine-conflict-start-with-these-two-simple-questions). I have highlighted the sentence the reader skipped. Do I have a setting not marked properly? What can be done to fix this?

Hello,

Clicking to open Firefox gives me the following error message:

Error. Platform version '120.0.1' is not compatible with miniVersion >= 120.0 maxVersion <= 120.0

Can't open firefox! I'm running Windows 11 version 10.0.22631 Build 22631

Thanks! Julie

I had 2 windows open, closed one, lost all of my tabs. Restore didn't work. I tried to restore by renaming session-store-backups folder files. doesn't work. There is a file called upgrade.jsonlz4 from November, maybe that could be used to restore tabs somehow?

Website fonts are often garbled. See attached screenshot. I've tried the other suggestions mentioned here but nothing changes; it's still happening. I'm on a 2020 iMac with a 3.3 GHz 6-Core Intel Core i5 processor with Mac OS 14.1.1 and Firefox 120.0 (64-bit).

Help?

Hello, every once in a while Firefox on my Win 10 PC resets bookmarks, logins and saved tabs to ones that I used several weeks/months ago. I also remember that it once switched back to a newer instance a few days after switching to and older one. When I try to open the app, it also creates a new icon on my taskbar. This has happened around 4-5 times in the last year. Does any one have an idea what the problem might be? Thanks in advance!

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).
