Fóram Tacaíochta Firefox

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.

After the last update (October 7th), SOME videos stopped playing for me. They just show an error. On the same YouTube, some video plays normally, and some gives an error. Tried safety mode. Already tried disabling add-ons, checked all settings. I did everything that was in the FAQ. Did not help. Everything works fine in other browsers. And I can't understand the pattern of videos NOT playing.

The issue I am having is that I wiped my old iPhone before disabling two factor authentication. I am not able to login because Firefox wants a code from my old device.

Please advise.

"If you have two-factor authentication (2FA) setup on your account and need to migrate to a new device or phone, here are steps you can take to ensure that you don’t get locked out of your account. Step one: Disable two-step authentication"

   "Go to https://accounts.firefox.com/settings (you may need to log in).
   Enter the authentication code from your authentication application.
   After login, under Security next to the Two-step authentication click Disable.
   Click Disable on the confirmation".

Good morning, I have problem with printing on Firefox. On the earlier version view in the filed printers look:" name_printer on print server" but now its look: "\\print_server\name_printer". Please check this because this problem occurs in many users in my company.

This problem not occurs in Google Chrome. Thank you for handling the matter quickly. :)

Amazon Sign-in problem started on 10-15-22. Amazon does not accept my password and asks me if I would like to receive a text message for verification. There is no yes or no selection displayed. I select resend text and I am given a telephone number for Amazon customer service. I go thru a 15 minute security verification process and Amazon tells me if I do not answer any questions correctly, they will cancel my account. On the 2nd time I contacted Amazon, I was told to use Crome browser and not to use Firefox.

This problem happens with my personal computer (windows 10) only. My Android phone using the Amazon app works with no problems. I can also use Crome browser on my computer and Amazon works fine.

Any suggestions ? Thanks

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.

Dashlane extension is blank - couldn't see anything in the window when I clicked on the Dashlane icon but now even the window doesn't open. What's going on?

I've used Dashlane for years without problem. I'm on Firefox 105.0.1 and OS Monterey 12.4

I can change the color of links and background in Firefox options. But i want only to change the colour of visited links on all pages and NOT also the colors of background and text. These 2 options are connected which is not practically i mean.

Are there addons who could do this? thx

[See uploaded image]

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?

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

disable pop=up sign-in with google prompt LAPTOP WINDOWS 11 FIREFOX 105.0.3 64-BIT 1. Over the last few days I have been getting a sign in with Google prompt on most websites I visit. Please refer to the photos. This looks identical to the Google generated promt, however in my Google account settings I have this option turned off. Is this a Google bug or a Firefox thing? With all the other annoying popups these days, this is just another irritation frustration to view a website.

I USE DEV TOOLS from FIREFOX TOOLS TO FIGURE OUT IF IT'S FIREFOX OR GOOGLE CAUSING ISSUE. HERE IS ONE OF 50 LINES RELATING TO GOOGLE/TWITTER/FIREFOX CONVERGENCE

(ALSO, I USE UBLOCK & LASTPASS)

LINE FROM DEVELOPER CONSOLE WHEN I OPEN TAB TO TWITTER LOG-ON PAGE:

20:36:03.881 Google Analytics and Tag Manager is being shimmed by Firefox. See https://bugzilla.mozilla.org/show_bug.cgi?id=1713687 for details. sandbox eval code:1:9

I DON'T WANT TO CLOSE THIS POP-UP BUTTON EVERYTIME I GO TO LOG IN AT TWITTER, IT'S NEW. I HATE IT. HAVE DELETED TONS OF UNKNOWN FILES IN MY USER FOLDERS TODAY, NOTHING HELPED (LOCAL/GOOG FOLDER & TEMP FOLDERS). MAYBE I NEED TO RESET SOMETHING IN CONFIG OR A REGEDIT SETTING FOR FIREFOX. I'LL DO ANYTHING. Thanks!

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?

After several years using Firefox my log in to GMail ceased to work. The address shown (https://mail.google.com/mail/u/0/?pli=1) when I tried to log in produced no response whatsoever. Other websites loaded normally.

I tried Chrome instead and logged in successfully. I have restarted my computer but the problem remains.

Hello,

I'm having a trouble connecting to WSS websocket. I'm using self-signed certificate.

Firefox shows in the console: Firefox can’t establish a connection to the server at wss://127.0.0.1/...

I have tried with private browsing and with troubleshoot mode.

Works out of the box in Chrome and Brave.

Firefox: 105.0.3. OS: Ubuntu 22.04.1 LTS

I need to reinstall firefox totally and I cant due to it says my password is incorrect even though it is saved in the browser. I have massive issues suddenly i cant correct and I have things i cant lose by reinstalling as a new user Ideas  ?
