I'm using Firefox 116.0.1 on Ubuntu linux. I'm not using a VPN, antivirus, a proxy or any kind of http filtering.

When attempting to load a certain website I get the message: "An error occurred during a connection to www.[website].org. PR_END_OF_FILE_ERROR"

Google results tells me that firefox throws this error when it can't resolve a safe SSL/TLS connection to the website.

The thing is, I don't care. I'm aware of the risks of browsing on a website with outdated or non-existent certs.

How do I get firefox to drop this security measure?

Firefox for linux ubuntu is what I'm using on my laptop. I installed browsec VPN and it does not launch. I've used this before linux mint and I did not have any problems.

I found that when starting Firefox on my school's WiFi, it starts up very slowly. Using `strace`, I found that it was taking it's sweet time making a DNS request to try to resolve my computer's `/etc/hostname`. After searching the Firefox source code with https://searchfox.org/mozilla-central/source/, I found that the only occurrence of `/etc/hostname` was in [SandboxTestingChildTests.h](https://searchfox.org/mozilla-central/source/security/sandbox/common/test/SandboxTestingChildTests.h). So I was wondering if it's possible to disable these tests when Firefox starts up.

Firefox 111.0.1 (64-bit) Latest update seems to have altered the way the toolbar book marks work. The bookmarks do not display, even though there is a line reserved for them at the top of the window.

I'm becoming less and less likely to customise how firefox works from the default setting, because over time I cannot be certain that these customisations will disappear or become non functional.

Hi there! I installed Firefox on a new computer, set up my sync account and don't have (or see) all my passwords.

I had almost 300 passwords, now I have 60~ passwords on my new PC.

Can anyone help me?

How do I prevent firefox from redirecting to HTTPS when it can't find the HTTP website I typed into the address bar?

Background (please read) I run a website for my team at work off my local machine. It's just http, because it's local, and I don't need any fancy encryption schemes. I have no domain for it ... me and my users just type the local IP of my machine. Like this: http://10.111.111.11/myapp/login.php

To work from home, I set up a VPN tunnel thru my workplace firewall so I can hit the webserver on my local machine. If I forget to start the VPN tunnel on my remote machine and then try going to my website, I get an error message in firefox:

   Unable to connect
   An error occurred during a connection to 10.111.111.11.
   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

After receiving this message, Firefox changes the address in the address bar from what I typed to the same thing, only with "https" instead of "http". This drives me insane. How do I force Firefox to preserve what I typed in the address bar EXACTLY as I typed it?

i tried changing any and all settings, clearing cache, using troubleshooting mode etc to no avail.

i use fedora 38 beta (it was also a problem on 37 stable) with ffmpeg installed.

i use biwarden, sponsorblock, ublock origin, stylus, google container, youtube shorts block and some custom css.

i am running a system with an i3 10105f, an rx 6600 and 16gb of ram.

firefox is installed with the version off of the firefox website.

reinstalling it worked briefly, but it broke again after a little bit of time.

i am sorry if i did not provide adequate information.

How can I stop firefox saving the same file twice at all while downloading? I don't know any scenario, where saving a renamed copy makes any sense. But I know scenarios, where this is deeply confusing.

I found this answer: https://support.mozilla.org/gl/questions/1365576#answer-1477483 , but it doesn't help much.

It only works if the downloaded file is not one of the type configured in "Applications" part. Action other than "save file" or "Allways ask" does ignore "Always ask you where to save files" setting.

So, is there any switch "never save renamed copies of the same file"?

I'm wondering if disabling the automatic updates for Extensions/Add-ons we get any notification when an update is available, without going in the Settings where the Add-ons are listed.

Will I get any notification or indication while browsing that an Extension/Add-on has a new update, if I disable the automatic updates?

I'm referring to the reply from Paul here that tried to sell us the useless floating tabs "feature". Now, several years later, there's no sign of any of this, and we still have to deal with the downsides of floating tabs.

Hi! Is there a way to store my username for some website without storing the password itself? i use an external password manager so I do not use firefox's internal one. I've tried storing a login with an empty password entry but it wont accept it

Dear Support, I posted my js-library on the hosting https://rombase.ru/o5/olga5/o5.js and copied it to https://leonrom.github.io/o5/olga5/o5.js

I try to connect to it from Blogger, for example: https://olga-5.blogspot.com/2020/02/olga5-shp.html?o5debug=2 and I change the link to the library's hosting in the <head> of my blog.

The Chrome browser works the same way wherever o5.js is located. But Mozilla, when placed on rombase.ru, swears in the console: `The resource at “https://rombase.ru/o5/olga5/o5.js” was blocked by Safe Browsing`

My Firefox is 109.0.1 (64 bit) under MX Linux

Could you please tell me: what is the "safety"-difference between rombase.ru and leonrom.github.io? What shall I change in rombase.ru to work properly?

Thank you PS Connecting via VPN (from Ukraine) does not help

Hello,

I am a developer and I am working on a project but it is next to impossible for me to share my staging server cookie on my localhost project which I am running locally. I have tried multiple possible ways which was listed on google and even on chatgpt but nothing is working out. Please help me out with this disaster.

Thank you for you support which I am expecting urgently.

After running `snap refresh firefox`, many sites I use no longer render any text.

Via some fiddling via the developer console, it appears to be that any text with `font-family: Helvetica`. Removing that CSS restores the text, adding it removes the text.

There's a fix for CVE-2023-29537 in this release that affects font initialization - possibly related?

Firefox 112 Mint Linux

The web site for my VOIP company lets me set phone numbers as "contacts" via a web form.

I started getting an error message along the lines of "Error Adding Contacts".

I restarted Firefox in --safe-mode, the site worked.

I restarted Firefox in normal mode. I then turned off each extension, one by one, refreshing the form. I ended up turning them all off and the contact form stayed broken.

What else does --safe-mode turn off besides the extensions?

Thanks.
