Firefox Community Forum

The Issue: Hello. About a week or two ago, multiple sites (Including my personal site) started giving me a "Warning: Potential Security Risk" message (Error code: SSL_ERROR_BAD_CERT_DOMAIN) and won't let me access them. When I click "Accept the Risk and Continue," I then get a "403 Forbidden" error that says "Cloudflare" under it. These sites work fine if I load them through Chrome, and I've had two other people try this on their own Firefox browsers and the sites work fine for them.

Websites Affected: I've seen this on several different websites, but here are a few specific ones that are giving me this issue:

• https://guessthe.game/
• https://hard-drive.net/news-games/the-hard-drive-review-grapplers-relic-rivals/
• https://paulkankiewicz.com/

Things I've Tried (That didn't work):

• Restarting Firefox/router/computer
• Clearing browser cache/history/cookies
• Disabling all addons/extensions
• Starting Firefox in Safe Mode
• Waiting 1-2 weeks to see if it would somehow fix itself
• Changing Hambuger -> Settings -> General -> Network Settings -> Configure Proxy Access to the Internet to "No Proxy" (This was suggested in another help ticket, but didn't work for me)
• (For my personal site) Contacting WordPress support - They said everything looked good on their end, and since it's happening with multiple sites, it's likely not them anyway

This works, but probably isn't the "correct" solution: Hamburger -> Settings -> Privacy & Security -> Enable DNS over HTTPS using -> Off (Note that this was previously set to "Default Protection," but I have the Security Risk warning if set to that)

Is this a bug with Firefox that can be fixed, or is there something that I can do on my end to fix this issue? The only other things I know of are to 1) Try uninstalling/reinstalling Firefox (But I'm worried I'd lose all my bookmarks/settings/configurations, even with my profile) or 2) Use another browser (But I really like Firefox). Thanks for the help.

HELP! I've been with Firefox for decades and I've lost the Icon for Firefox (left main screen) and the icon on my lower power bar to summons Firefox. I'm asking you as there is no phone number for Firefox support and I need those icons. PLEASE HELP or show me how to re-create those icons.

This topic appears to show up a few times, but none of the solutions work for me (eg they were using A/V or "it just worked"). The error I get is also different.

This a pretty fresh install (migrating from Chrome so I'm currently re-logging into all my sites to ensure I can access everything I need.. and going through MFA hell heheheheh).

Everything is mostly fine, except for Synchrony Bank.

I go to login at https://auth.synchronybank.com/account/login, enter _any_ username or password (doesn't matter if I enter the right details or the wrong ones), and as soon as I click "sign in" I get an error page

Looking in developer console, the error reason given is NS_ERROR_NET_INTERRUPT while trying to POST to auth.synchronybank.com. Every so often I get PR_IO_TIMEOUT_ERROR but over 90% of the time it's NET_INTERRUPT.

This occurs also in private browsing and also in safe mode. I even created a new profile and tested it from there; same issue.

I've tried lots of things related to this (eg setting network.http.http3.enable to false), added the domain to the advanced tracking exception list, and I'm running out of ideas.

I can see traffic flowing to akamai but (it being https) I can't see what's inside the traffic. Could akamai be objecting to something in the content?

FWIW, I can login with Chrome on the same machine.

I have a situation where I constantly have to send tabs from mobile Firefox to desktop Firefox. So I use Send tab to device feature. But when sending, manually clicking on the Synchronise now button in the Account menu of the toolbar of the receiving device is often needed, or else it would take a while for the tabs to be received. But I find that annoying and unintuitive.

Is there a solution for it? For instance, syncing Firefox devices more often, maybe just for the sending tabs feature because sync-now also syncs history, and bookmarks.

I had a situation where multiple people who I know in real life managed to hack in to my Firefox account, and I wanted to ask if it is possible to request a history of the "Connected Services" from Mozilla that is available in Settings? I would really like to go back in the last 12 months if that is possible.

I have tried everything. Cleared cache, uninstalled and reinstalled the browser, deleted outlook off of my computer, got rid of adblock. Nothing is working. I get the 500 error with the page refreshing over and over before that.

This is what the screen says:

500 Something went wrong. Repeating redirects detected.

what is the largest file size i can download with Firefox.

I am using Ubuntu 22.4 LTS and want to download 123GB Zip file from Microsoft One drive. After downloading 100GB it stuck and stops downloading at 100GB. How can i download it. 

Previous year i switched from windows 10 pro to Ubuntu. At that time i have my college mail account where i compressed all my data and uploaded it. Now i want to download that zip file.

Every time I try to login, the progress resets. I enter the password enter the verification code and it brings me back to entering my password. The cycle repeats again. Before this, the account would log out automatically while syncing.

I cannot print from Firefox. It worked fine, and then stopped. I'm not sure what changed. It doesn't matter what printer I use. Even printing to PDF fails. No errors appear, and nothing shows up in the printer queue. All the other applications in Windows print just fine. It's just Firefox. And just for this one Windows user.

I tried clearing the saved printer settings in the about:support page. I tried refreshing Firefox. I tried uninstalling and reinstalling Firefox. I tried uninstalling, removing the mozilla folder in %appdata%, and reinstalling Firefox. No luck.

The only time I can get it to print anything is to log into a different user account on this same PC. Printing from Firefox seems to work then.

It seems there is some user-specific printer setting/file/whatever that is messed up. I'm not sure what else to try.

Thanks.

Hi,

If I visit the same webpage twice in the Firefox browser, Firefox no longer shows the first webpage visit in the Library > History window. In this window, I would like for Firefox to show all visits to a webpage. In this case it should show both the first and second visits to the webpage, with timestamps to indicate the times of each visit.

Is there any configuration that I can make to Firefox that can achieve this?

Thank you, James Pedersen

I like using Firefox but it is increasingly becoming incompatible with more and more websites. There is nothing wrong with the websites, I can login using Google Chrome just fine. Firefox simply won't allow me to login to certain websites that I was able to access using Firefox before. Anyone know why this is happening?

I have not noticed this before upgrading my Mac to Sequoia 15.0, using latest Firefox browser update, but "printing to PDF" which I used in the past extensively, makes a PDF file that causes the letters to be one ASCII number off. So if I type into the "search" field "p", then all the "o's" are highlighted. I can only enter a search term if I usean "ASCII number +1" technique, so I can search for "get" by typing in "fds". Numbers are searched for as in the past. This is not happening if I make a PDF using my Safari browser, all the PDF words are correct and searchable as in the past. Anyone have insights as to why this might be occurring? I will try restarting in "safe" mode and re-downloading Firefox as is suggested in some of the articles here. Thanks!

For the past few days now I've been getting a PR_END_OF_FILE_ERROR when I try to use certain websites such as Reddit or Tumblr. The problem occurs on both my PC and mobile when using Firefox. I can access the websites just fine using other browsers.

I've tried the solutions listed here: https://appuals.com/pr-end-of-file-error/

But none of them have worked. I've also tried renaming the 'cert9.db' file in my profile folder, but that hasn't worked either.

I make invoices for work and need to enter a dozen addresses every day. For every one of them Firefox pops up and asks if I want to update my address. No. I never do. I have the "Save and fill addresses" box ticked off, I've tried with it ticked on as well. How do I block this box from ever showing up? If I ever move I'll update it manually. This used to not be a problem but it just started happening recently.

I use Firefox on my Mac Mini. For some unknown reason, when my Firefox home page has changed from opening as a full screen view to a small box in the upper right part of my screen. Then I have to change it to the full screen view. I would like to find out how to get it changed back to always opening with a full screen view, please. Also, why is there no customer service phone number posted? Some of us prefer phone support, rather than typing questions and hoping someone knows the answer and takes time to respond.
