For the last several weeks, one of my computers when it updated to the new settings menu (version 156ish?), it has lost the ability to maintain some of the synced profile settings. For example, I have a couple websites that I list in the exceptions to not have Firefox clear the cookies, and I additionally have the clear cookies and site data check box enabled so that every other website I visit clears upon exiting. This is the setting combination I have utilized for years to keep the cookies from only 2 websites and clear out everything else.

On one of my computers, I'm able to add the exception, and as long as I do not close Firefox, the website exception settings stick. However, as soon as I exit Firefox, and open it back up, the settings clear themselves again, and I have to manually enter the exceptions again. This is very frustrating because one of the sites that I keep the cookies on the exception list has multiple different logins saved so that I don't have to manually re-login to every time I open Firefox.

I have attempted a refresh, and that did not fix the problem. I have fully uninstalled Firefox, manually deleted the %APPDATA%\Mozilla\ folder contents, reinstalled foxfire and this too does not fix the problem.

The weirdest part of this whole issue is my laptop, does not have this problem and the exceptions are sticking so I know that this setting combo works. Additionally, I have tried unchecking the clear cookies and site data box and this too is not allowing the exceptions to stick.

I have also tried re-syncing my account to pull the settings from my laptop and this too is not working.

This experience is on Firefox 157.0.1 (64-bit), Windows 11 Pro 26H2

Thanks for your time and please advise as to how to fix.

Greetings, I am on the spectrum with aspergers. I have issues with organization, lining up objects, etc, but I am highly intelligent and present well. I have no doubt society is aware of all the tropes that surround folks with my......difference. I have an incredibly hard dealing with change, and it sometimes wrecks my mental health. The changes are constantly throwing my health and welfare for a loop, and it is really harmful.

Everytime I get firefox setup to where I am comfortable, something new gets shoved down my throat. How to stop the constant feature change diarrhea abuse is inflicting on my health? Recent example. I only use 2 search engines, and I cant deal with the rest, its a colour thing sorry. I have had my search engines set up like this for 14 years.

Recently, firefox decided that I should go for another life rollercoaster, even though I didn't ask for it, and that I should permanently have things like history bookmarks tabs and actions as search engines, and they shouldn't be removable.

I don't have a history, as I value my privacy. I don't have bookmarks, because I remember everything and it sucks, and I type about 350 wpm. Tabs information is within history, so I see firefox as duplication idiots in this case, and I don't do any actions, not even sure what they are and I really don't care at all.

My parents are considering a lawsuit against firefox for accessibility issues like this, as 1 of my dad's best friends is an accessibility lawyer.

How can i stop firefox from constantly flipping my autism world upside down? I don't want my parents to sue them because it will bring a lot of attention on me.

Please help me re-normalize the internet for spectrum users.

How do I turn off yet another anti-privacy feature sponsored by Google Tracking(tm)??? The d* check-box is grayed out; the 'Manage Firefox Suggest' redirects back to the grayed out option. Know your audience.

I have been having random crashes Firefox Snap on Kubuntu 24.04 (and now 26.04). Sometimes Firefox will run stably for over an hour, sometimes it will crash in less then a minute from (re-)launch. I have tried the usual troubleshooting steps of 'run in troubleshoot mode', 'refresh', disable plugins, but the crashing seems to happen even when running in troubleshoot mode. I also have not been able to figure out any kind of event or user-action that triggers the crash; it might happen while browsing, it might happen while I am not even at my computer. At first I thought 'the Devs will handle this', but it has been some 6 months so I think my case is not very common/pressing to the community. I'd like to take a more proactive approach in solving the problem. I am still a novice at software fixing, so I might have skipped or missed a very basic step in the '10 things to try to fix Firefox'.

My system • Windows 11 on a Dell laptop. • Firefox Version 157, my default browser. • Norton 360 Standard. • Two Firefox profiles; the warning appears in both. • Firefox Troubleshooting Mode does not eliminate the warning https://support.mozilla.org/en-US/kb/sslkeylogfile-warning?utm_source=chatgpt.com

What I have observed The warning appears on Firefox network-error pages, including when the internet is disconnected or I enter an incorrect URL. A particularly reproducible example occurs after I successfully log in to Kotak Net Banking and select Help → Raise a Query. Firefox then displays a connection/privacy warning associated with the embedded page. I do not see the same behaviour in Chrome or Firefox Private Browsing when performing the equivalent Kotak steps. Troubleshooting already completed 1. Norton Safe Web HTTPS scanning was disabled and re-enabled without resolving the issue. 2. QUIC/HTTP3 scanning, WebSocket Protocol Scanning and DNS/DoH scanning were individually tested without resolving it. 3. Firefox Enterprise Policies are inactive. 4. I found no SSLKEYLOGFILE entry in either Windows User Variables or System Variables. 5. Norton and Dell malware scans found no malware. 6. The warning also occurs when I connect through a mobile phone hotspot rather than my usual BSNL connection. Questions for Mozilla's technical contributors 1. Does this warning establish that Firefox detects SSLKEYLOGFILE, or could another mechanism produce the same message? 2. Can the variable be inherited by Firefox from a parent process or injected into its running process even when it is absent from the Windows User and System Variables? 3. What is the safest way to identify which process or security product is setting it on Windows 11? 4. Is there a known interaction between Firefox 157 and Norton 360 Standard that could explain this behaviour? 5. What evidence should I collect to distinguish a Norton issue from a Firefox issue without disabling security protections or modifying Windows settings? I am not looking to disable security features indiscriminately. I want to identify the actual cause and, if Norton is responsible, determine the precise setting that needs attention. I would particularly appreciate a response from a contributor with Windows networking, Firefox TLS or security-software diagnostic experience. Thank you.

Is it really not possible to adjust the font size? I found no setting for that. I only can cheange the text size of webpages, but not for title or menueor other thing a the top of the firefox window. These are readable with thunderbird, but not with firefox after I changed to a new laptop with higher resolution. Size of elements should be measured in points, mm or inches an not in pixels, as pixel sizes are depending on HW. The attached image shows the comparison between thunderbird and firefox.

hen I click on my home page or Fire Fox it has a section on soccer. Since i dont watch or am i interested in soccer; how can that be deleted. After deleting it how would I add Nascar?

Hello,

I’m the developer of SnakeGame.Live , a browser-based multiplayer snake game with mouse steering on desktop.

I would like to understand the difference between Firefox’s F11 fullscreen mode and fullscreen activated through a website’s Fullscreen API.

For a mouse-controlled game, do these modes behave differently when the pointer reaches the top edge of the screen? Is there a recommended way to let players use fullscreen while keeping Firefox’s normal exit controls available?

I’m using Windows 10. I would appreciate guidance on the expected Firefox behavior and any relevant support documentation.

Thank you.

The access to the email I used to sign up for my Mozilla account was revoked without warning earlier this year. I can't change the email address because it insists on sending an authentication code to the email address that no longer exists. There doesn't appear to be a way around this.
