Firefox Support Forum

While exploring about pages in Firefox, I came across about:profiling. I'm not sure what exactly it does, but since I've been to it, a profiler icon has been added to the toolbar and I can't find any way to get rid of it completely (only ways are to hide it). If it could be added, there must also be a way to remove it? How can I close it?

What is with Firefox lately. Endless problems with screen sizing, light dark mode. But what is really pi**ing me off is the inability to connect to certain web pages. No I don't have a any spyware or viruses (I have scanned with 3 different programs) and I have no problems with connecting to the pages with Chrome or Edge. I'm getting the error messages

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.amazon.ca because this website requires a secure connection.

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.ebay.ca. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. Firefox detected a potential security threat and did not continue to www.google.com because this website requires a secure connection.

Did Not Connect: Potential Security Issue Firefox detected a potential security threat and did not continue to www.google.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.Error code: SEC_ERROR_UNKNOWN_ISSUER

And I get the same warning with Amazon, eBay, my email client Shaw Mail, Google Search, and several other pages that require a login. Is there anything I can do to fix this as I'm really starting to rethink my preferred web page browser?

My Firefox (Windows 10) updated to 105.0 this morning. I have https://www.google.co.uk/ as my homepage and Firefox always used to focus on the Google webpage search bar on startup.

Now it focuses on the address bar instead (i.e. https://www.google.co.uk/ is selected). How can I make it focus on the webpage search bar on startup again instead?

I already found this thread from last year https://support.mozilla.org/en-US/questions/1334131 and tried changing browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false but it didn't have any noticeable effect and the issue is still present.

Many thanks.

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..

I don't know what this is, what it's called, or why the someone in your UI/UX team continues to think that it's a good idea to change the keyboard navigation in the browser with all these new, special, or whatever controls that are ultimately useless.

How do I turn this off?

Hi, I'm a very happy long time Firefox user. I use the extension "Dark Background and Light Text" so that my webpages are much more easy on my eyes. The extension works everywhere but in "support.mozilla.org".

How is it possible to have dark theme in Mozilla's support pages too?

Thank you very much. Prayan

I have been having an issue for a week or more and no updates from the browser seems to fix that. The error reads: Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. This is occuring with a request to RBC banking. The same appears to be true but witrh different language for a request with Desjardins Insurance portal.The second link printed in red is the result after I cleared all cookies from Desjardins site. I can access many other pages within the two sites. RBC I am logged in (In black). Desjardins I am not yet as a user when these errors come up

I told Firefox to never remember a website login user/pass but now want to revert this. I have looked for this option but can only find the remembered user/pass. There is an option at the bottom of the chrome password list, but not in firefox.

Can someone please point me to the area that i can remove this "never remember logins for this site"

Thanks in advance

I use both firefox and firefox dev edition. Deleted the dev edition and reinstalled the latest one, now i'm getting the error below on attachment. I did not just uninstall the dev edition but i manually cleaned the directorys: C:\Program Files\Mozilla Firefox Dev Edition C:\Users\User\AppData\Local\Mozilla\Firefox\Profiles C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles

Firefox still works but the new dev edition after fresh install doesn't

Hello, I'm currently running firefox developer edition and i'm facing a weird bug: When firefox is started, opening a web url from outside of firefox window does'nt work and display error message: "Firefox is already running but is not responding...". It expects that i close all instance of firefox instead of just opening url in a new tab.

Do you have any idea?

I'm working on version 105.0b2 with two profiles on an ubuntu 22

As of today, I'm seeing black text on the black background of every site with a dark theme, including Google Search and Github

I'm running Firefox Developer Edition 105.0b8 on macOS 12.5.1. My macOS Appearance is set to Dark

Switching the Website Appearance config setting between Firefox Theme, System Theme, Dark, or even Light does not change the colour of the text

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you

Hi all; once again and seemingly too often, a Win 10 BSOD and Firefox was reset and where are my bookmarks ? Normally I had them on the LHS of the page but this is getting too much as I cannot find them anymore. Can someone give me a nudge to where I can find them ? rJ

I am honestly in chock with Firefox's terrible decision of not providing any option for the user to delete downloaded files.

It is honestly amazing that they came up with such a terrible decision. My downloads folder is a complete mess now and there seems to be no way to fix this.

I don't understand why not just provide an option for the user to only open files. People should be able to choose their settings.

I refereed to this previous post and the solution there didn't work: https://support.mozilla.org/en-US/questions/1370409. By setting browser.download.improvements_to_download_panel to false.

Is there actually no way to only open files now?

I have it set in setting to open in Firefox. it is continuing to automatically download all PDFs and it is eating into my data! please help. I have to get this to stop or I will no longer be able to click on any PDFs with Firefox anymore. I have also tried setting it to always ask, but if I do that and then tell it to open, then it STILL DOWNLOADS THE FILE! I cannot understand why anyone would ever want files they just wanted to read to just randomly download. I am a genealogy researcher and used to click on dozens of PDFs a day to read, now I can't with Firefox or I won't have internet for half the month after I use up my data. There has to be someway to stop this, I don't like other browsers, but right now, if it involves a PDF I have to use a different browser. (also quite annoying to have to delete multiple files that I never wanted to download - I was using Firefox to pay a bill and downloaded it SIX times) Please help!

Hello, I have a problem with this website: https://murf.ai/studio/project/2/P0166570108644041F The main page shows everything normal but when I go into my project some codes show up on the page...please have a look at the attached screenshot. In all other browsers this problem does not occur... I have no idea what causes this problem ??? Have tried to switch off all extensions, but this did not change anything. I hope that someone can help me out with this issue. Thanks in advance to everyone who can help. Peter

Ever since yesterday, scroll click (I use it to scroll through websites) has stopped working in Firefox. Works in in programs, other browsers, etc., just not Firefox.

Whats weird is it still registers a click when I use it, so I can lick on links with it if I want, but the function of scrolling, either by clicking once and using my mouse to go up and down, or by clicking an holding, no longer works.

I've tried disabling add-ons, incognito mode, nothing seems to work.

I do not have a G account. For work related purposes I have to utilize websites that bombard me with Sign in w Google. No settings within FF I found can stop this onslaught. Same goes for Ad Block Plus and a few others since disabled and deleted. No useful information on G's forum website. Firefox, I was under the impression your about user safety & security? Why O Why do I get this garbage from G daily in your browser 105.3 on Win 10 home without a way to disable it?
