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?

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

Greetings!

I would like to be able to open selected links via the search tool with CTRL + Enter, like it is possible on most browsers. Basically, I do CTRL + F, select a text which brings me to a link I was looking for, and do instantly CTRL + Enter to open this link. Currently, this shortcut only toggles the ability to see all matched texts and doesn't open the link.

Do you know if it's possible? Thank you!

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.

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

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

Hello, I know when I closed the firefox browser , I can reopen firefox browser and click "settings"-- " history" --" Restore previous session" to retrieve all the webpages I was viewing last time. but this time it seems I made a mistake . I closed the firefox browser in the beginning with many valuable webpage still opened, after I restart the firefox browser, I close the browser by accident without firstly reloading all the restore previous session . Then I have to open firefox brower again, and try to click "settings"-- " history" --" Restore previous session" to try to retrieve all the webpages I was viewing in the first time. but this time no previous session can be loaded. since those webpages I was viewing are important webpage I need to check, May someone tell me how to get those valuable webpage link again? I know I can try to find those webpage link slowly by checking all the history day by day. but honestly speaking, I have 15 around webpages in the firefox brower and some of them are viewed around 20 days or 30 days before . I haven't closed my firefox browser for almost 40 days so it will be very hard for me to search the history webpage to find out them one by one. I am not sure whether there are some tips to try to load the "restore previous session " again for the first firefox browser I closed.

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 use Firefox 105 on my PC. I have embedded various YouTube videos on my website. I've had the following problem for a few days: I can see my videos on both my smartphone and tablet without going to YouTube. On my PC (Win 10 Pro Vers. 21H2) the display wheel "rolls" without opening the video (... "an error has occurred, try again later"). But if I click on: "Watch on YouTube" plays the video via YouTube correctly. Does anyone have any idea what might be causing this? Is there a wrong setting in the Firefox browser? Many thanks and best regards Helmut

So this problem is isolated with Firefox as it doesn't happen with Edge or VLC on this pc. If I have Twitch or Youtube, probably any other audio or video playing, open when I turn the monitor off the audio will no longer go through properly when it is turned back on. The video is still playing fine but the audio isn't going through properly. Refreshing the page fixes the issue.

I have made sure to disable all other audio outputs and defaulted the current HDMI output. Audio playback works fine on every other application that I have tried.

Running Windows 11.

Since Firefox for Windows upgraded to 105 the Wordle web site fails to work - it displays the grid at the bottom of the window with no scroll possibility & it displays that even when a correctly working browser displays my statistics.

The website works correctly on other browser (Chrome & Edge), on Firefox for Android and on Firefox for Windows 104 (luckily I had a machine which hadn't been on for a few weeks and therefore was no up to date).

The attached images show the website as it should be (on Chrome) and as it appears on Firefox 105

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.

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

See that last option? i never want to see another Search Engine suggestion again by right clicking the address bar. This should also be a standard setting if it's going to be present in the first place.

I installed mozilla today and I looked in to my settings and found this message "Your browser is being managed by your organization."

I am not part of any organization since this is my home pc.

I checked the forums but i couldn't solve this.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox and HKEY_CURRENT_USER\SOFTWARE\Policies\Mozilla\Firefox doesn't exist for me and i don't use avast.

On about:policies it shows "Certificates-ImportEnterpriseRoots-true"

What is this ImportEnterpriseRoots thing?

I'm using a laptop with windows 11.

Can anyone help?

Today the autofill feature for passwords / username stopped working on Protonmail login. Windows 10. Specifically the username option. I have two accounts and formerly could select which account. Now i have to enter the username manually, however the password tab still works for password autofill / selection. This is the only site I am having this issue with.

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
