Hello, I always use Firefox logged into my Mozilla account.

Yesterday I went to a (legitimate) site, that I had never visited before and only read one page. I didn't click on anything on that site/page, I only read that one page and left the site. Not long afterwards, I received a promotional email from that site stating "Thanks for stopping by!".

My question is: how did they know my email (the email used by my Mozilla account)? I have never received emails from that site, and as I said, I never visited it until then.

Does Firefox expose the Mozilla account email when visiting sites? This is pretty troubling. I would appreciate any input you have. Thanks

Twitter not working properly on Firefox (Volume on videos can't be changed, hovering over buttons doesn't do anything and font looks a bit off, could be just Firefox font or something) works on chrome and other browsers.

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

Firefox has been crashing multiple times per day for several weeks now. It used to be fine, hardly ever crashing. I can't think of anything I'm doing differently since before the crashes started. I can only assume that it started after a specific Firefox update. I do have a lot of windows/tabs open at once, but that was never an issue in the past. Occasionally individual pages will crash, usually several at once. The entire software crashes all at once regularly as well. Sometimes the crash seems to cause other issues, such as my computer hanging up for a bit, or my monitors going blank and the graphics system seeming to reset, before Firefox actually crashes. I don't always get a crash report dialogue when the whole thing crashes.

I keep my Windows and Firefox up to date. I tried turning off hardware acceleration, but I think that might have made it worse so I turned it back on. I cleared the caches (which took well over five minutes), and ran speedyfox a few times. I exit Firefox through File > Exit whenever I need to restart or run other heavy software.

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

Dark Reader works for all sites except for mozilla.org, I think these webpages are over-ridden by the Firefox browser? I saw a couple archived posts recommending global changes for all sites via Firefox -> Settings -> Language and Appearance -> Colors, or to install themes. Neither option would work. I don't want to override all sites to dark globally, that's way to much change, just let Dark Reader change just mozilla.org.

Update to Firefox (120.0.1) in Linux Mint blocks CNN - its the only site which appears to be blocked. I get a message telling me that configuration of the site is blocking CNN from loading, and goes on as follows.

"" We apologize, but your web browser is configured in such a way that it is preventing this site from implementing required components that protect your privacy and allow you to view and change your privacy settings. This functionality is required for privacy legislation in your region.

We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser). ""

Rather strange, since I'm using Firefox.

In general, I am thoroughly annoyed with the way the Internet experience is increasingly fouled up by various sites implementing "safety" aspects. It used to be fun, now its a crap experience. Firefox is getting bigger, slower, and infested with site 'improvements' which do absolutely nothing for me - Is it so hard to provide a simple, clean, straightforward browser without so many 'add-ons' that its grinding to a halt? Time was software was written for the users, now its clearly written to give software developers something to do. Can't you create a revolution in software and do something useful, instead of "clever"?

Popups for Smithsonian magazine keep appearing, sometimes 2 at a time, despite having popups blocked. I need them to stop. They are annoying and cover up content of web pages.

As of recently, every time I try to watch someone on Twitch, where the video feed would normally be is the streamer's offline banner image. Chat is working fine, and is active despite the stream not being displayed on my end. If I check the Twitch mobile app the stream displays as normal, so I know they are currently streaming. I tried disabling all of my add-ons and restarting the browser to no avail. I am a noob, so please be patient with me. I have attached images of an example, but this happens with any live channel, not just ones I am following (I do not have any active subscriptions as far as I know).

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.

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.

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

I'm getting Access denied Reference #18.6b01cb8.1700662622.22a58314 only on tesco.com since last nights firefox update.

All other sites are funtional (at least no others found yet). I have cleared cache and cookies but still getting the issue.

The site is up and accessible by ms edge.

I have run in troubleshooting mode and taken off any extensions, still no change.

Running windows 10 (latest updates)

Malwarebytes is reporting no issues.

New computer, Win 11 and FF 120.0.1 all fresh installed and updated with latest versions. The double line spacing in bookmarks and all other menus is back. There was a fix for ver. 89 with the css file trick, but that DOES NOT WORK with this version. All other options I've run across don't work either. Why do the Mozilla software engineers think it's a good idea to break their flagship application every few years? Rhetorical question, I know.

Does anyone have a user fix that actually works with this FF 120.0.1 version? Something an experienced user can do that is not a programmer. analyst or engineer? I've been using FF since it first came out to challenge Microsoft's IE. Late '90s? I'd like to keep using it but this is too annoying to tolerate.

If anyone can help with step by step instructions, I would be eternally grateful.
