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 just had to clean install Firefox after having problems. I've pretty much set it up how I want it, except when I quit Firefox and then re-open it all the tabs come back. Which I don't want. The box in the settings page for opening with previous session is unchecked. What else am I missing? I re-started my computer just in case that was an issue but the problem continues. Thanks

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.

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.

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?

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!

Whenever I start Firefox as "New Private Window", I see in Task Manager, that Skype loads up into memory. Skype is Not found anywhere in any of the the Firefox Settings windows, not even as there but disabled. This does not occur when I open a regular Firefox window.

Since the latest Firefox update a few days ago, I am not able to log into my Outlook/Webmail account; nothing happens.

I can access it on google chrome but not on Firefox.

shoould i uninstall and reinstall mozilla firefox? as far as i know im using all the default settings. when i search the net it returns a page that im sure the site doesnt intend its text and other features to be so HUGE. I ALWAYS have to scroll down to get to a button.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Good evening, I have an issue related to ETP. Reading through several articles I couldn't find an answer to the following thing: How do you treat cookies set by Hubspot or GA4? They are a First Party cookie, but they don't always have samesite-parameter filled out.

I know that the lifespan is limited for first-party cookies. But I don't get whether samesite=none/empty makes a difference? Because data will be sent to a third-party server.

I'd be glad about clarification and your help. If you have articles covering this issue, that would also be great. Thank you for your support.

Best regards, Birga Woytowicz

Shortcut icons (4 rows of them) have disappeared from my Firefox home tab. After a Firefox update, they were gone. Just white boxes. I tried to re-enter shortcut information, but the box always goes back to white and empty. I tried a System Restore. That didn't work either. I depend on these shortcuts for my work and bill paying. Please, someone help me! Thanks!

Greetings. Lately, I am unable to log-in to some websites. This has started recently, about a few short weeks ago. The Social Security Administration and Electronic Design (magazine) are just a couple of example. I don't get much information from either of the sites. Electronic Design just replies with unable to log-in The SSA site replies with:

"Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

I cleared the cache, and reinstalled the latest version, Firefox 120.0.1, 64 I am on Windows 10 Pro 64, latest update AMD Ryzen 7 8-core 16GB RAM 1TB Samsung m.2 2280 system disk

Note: I have no issue logging in to the SSA website using MS Edge, but I'd rather use Firefox, which has been my default browser since Adam & Eve hit the earth! Your assistance would be appreciated. Thank you. Sam H. Electrical Engineer (248)677-1039

Firefox is my browser, and Outlook my email program. After years of troublefree access to Kickstarter, I now cannot link to the site, neither by Google search, nor by responding to an email link sent to me by Kickstarter. Instead, I get a message which reads:

'You are sending too many requests to Kickstarter at this time. Please contact support@kickstarter.com if you continue to see this error.'

I have contacted Kickstarter, but their response is that the problem probably lies with my browser. Do you have any idea why this problem should suddenly have appeared?
