Firefox Community Forum

I have been using Linux Mint 21+ since May of 2023. At that time I set all the Firefox preferences settings to what I've always set them to in the past, and have run Firefox with them ever since then. Now, about 3-4 weeks ago, I started Firefox and it came up with ONLY blue lines of text (not graphically). My Firefox homepage is "isp.netscape.com". I've waited until now to report the problem, since I was hoping that later Firefox updates would fix itself, but this did not occur with the 3-5 Firefox recent updates.

Originally, I posted the problem to the Linux Mint forums with the following title under SOFTWARE & APPLICATIONS: Firefox browser no longer graphical but only lines of blue text

Somebody there advised me to start Firefox in safe mode, which I did with this command in the terminal: firefox -safe-mode

and to my surprise, Firefox then came up graphically once again. However, going through the Firefox preferences and setting them one at a time, I came to what is causing the problem. Setting PRIVACY & SECURITY -> BROWSER PRIVACY -> HISTORY: "Remember History" to "Never Remember History" forces Firefox to reboot and when it comes up it came up with only blue lines of text, and not graphically.

One responder to my post on Linux Mint forums stated that it was also a problem with her on Windows 11. So, this is not a Linux Mint, or Windows 11 issue, but a Firefox issue. Mozilla made some change to Firefox back 4-5 weeks now that all of a sudden made Firefox come up in blue lines of text, and I changed nothing with Firefox since started with Linux Mint 21.3 1.5 years ago. I will add though, that ONLY my Firefox homepage (listed above) is the only page that is affected by this, every other website I visit comes up graphically.

What's UP?

I wonder why Firefox still doesn't have a session manager, it's beyond my comprehension. I've lost all my tabs and no way to recover them, even with all the hacks I could find on forums online. And why should I spend time searching for solutions anyway?! Firefox should save all open tabs at least once a day, am I asking too much? I used to have an extension active that did regular backups automatically, but it stopped working due to changes that were made in one of the most recent Firefox releases. Why we still don't have a decent session manager?!

Hello, PG&E just updated their webpage and it doesn't allow me to sign in. It informs me that Fire Fox isn't a compatible browser, all other websites are fine. It suggests Chrome as the preferred browser. We pay our utilities through their site and we enjoy Fire Fox.Can anyone help resolve this issue? Thanks

Whenever I try to use firefox I get the message:

Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

There is no firefox running and all I can do is close the windows. Pressing the on-screen button "Close Firefox" does nothing except for the error message to be reposted. I have to press the upper-right X to close the window.

I use Google Calendar in Firefox. The browser switches to the Google Calendar tab whenever a calendar notification occurs. It is really annoying, to say it in a polite way.

I think that the setting to turn it off is "Switch to this tab" in the page info (I go to calendar.google.com and click on the padlock in the address bar -> "secure connection" -> "more info" -> "permissions" tab -> dropdown with a list of website permissions)

I see this option set to "default". When I change it to "ask me", close the dialog, and re-open it again this option is set again to "default"!!!

What is happening? Any help?

I use Firefox 131.0.3 for Linux Mint and it is managed by my Linux Mint.

Dear Mozilla Firefox Support Team, I hope this email finds you well. I am writing to seek assistance regarding an issue we have been facing with Firefox. After some days of usage, Firefox prompts us to create a new profile, and the browser does not function as expected unless we do so. Here are the details: • We have installed the latest version of Mozilla Firefox several times (2-3 times). • We have also created new profiles, but the issue persists. • Despite these efforts, the error to create a new profile continues to reoccur. Could you kindly assist us in resolving this issue? Any guidance or troubleshooting steps would be greatly appreciated.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

Let’s come together, share tips, and ensure we’re all prepared. Drop your questions or insights below!

YouTube content doesn't load. Same with NYTimes.com articles.

Up to date, no extensions, no add-ons.

Running Sonoma 14.4.1

Safari and Chrome work as expected.

ETP breaks Teachable.com courses. Specifically because the domain player.hotmart.com is blocked. But this domain itself isn't used for tracking. Hotmart uses tracking-api.hotmart.com for tracking. So ETP breaks all websites that serve their courses via Teachable and there is no workaround other than disabling ETP for that site. Please whitelist Hotmart and add tracking domain only.

Hi, I had the idea to try Opera browser as I saw various videos about it. Firefox does slow me down at times even though it's what I have used for years.

Soon after, I defaulted back to using Firefox but the settings must have gotten changed. Everytime I wish to log in to any site, I have to type in my email again. The passwords usually are the old ones that show up.

With Amazon for instance. I must sign in and verify with codes sent to my mobile few times a day. I have searched for help online and gone through the cookies and history and privacy settings, turn this on or that off, don't do this and don't do that. Despite all that, the sites don't remember my email logins. If I go from voucher code to another site, it doesn't remember my credentials, so I don't get the deal or voucher. Amazon on my mobile works perfect but on my laptop, it's just a nightmare to have to sign in and verify each time. Outlook refuses to recognize my password most times and so it goes on.

If I cannot fix this asap, I will then have to remove Firefox as a browser altogether and find anything else that works! Please advise. Last time I reached out to Firefox, I never heard back! Fingers Crossed x

when opening o365 and open a PDF attachment that was fillable, I cannot view the filled in texts, unless i download the file and view with my default PDF viewer., even doing preview i cannot see the filled in portions of the document. I can view on Chrome and Edge and outlook app on my PC. I have attached a jpeg for your viewing, if you look at top part it shows what i get in Firefox, the bottom is with any other browser or office app. I am using windows 10 and the latest browser Firefox.

Thanks for your input.

And once again Mozilla managed to break with Firefox CSS scripts! (V131.x) The one thing that guaranteed always works with every update is that something doesn't work! The constant updates and the resulting "verschlimmbessern" until nothing works in a more. With every update there is another plug-in that doesn't work or has not been updated anymore as well.

V 130.x Outkick.com page does not load only a little bit of unformatted text. Foxweather.com images are huge page doesn't load completely. PG&E.com does not load billing information, blank page. Just to mention a few...

I have stopped recommending my clients Firefox I will no longer install it.

It appears that Microsoft Stream's new screen recording feature from browser either doesn't work in Firefox, or Microsoft has blocked usage in Firefox. No attempt is made to gain browser screen-recording permissions for the site prior to the following error message appearing.

When I down load my bank statements in (PDF) they are not readable. To get aropund this issue, I have to use Google. What I see when I try to open the PDF i get a BLACK screen and key board is locked up. To escape I do a Ctrl,Alt,Delete. This has been going on for some 5 to 6 months. When i contacted my bank they sugggested using another browser. There are other problems which have crept up, but I get around by using Google.
