Diễn đàn hỗ trợ Firefox

I tried to open my Firefox browser, but was unable to. Same thing with my Google chrome browser. I ran the troubleshooter for network problems, but unable to get a solution.

I downloaded a new Firefox browser in the hopes that it would let me access the other browser so I could retrieve all the settings, bookmarks, etc. However, everything disappeared when the new browser was installing.

Is there any way for me to retrieve that information or is it a total loss?

After the most recent update I have noticed that my shortcut icons are a lot smaller than they were. How can I make them larger because I do not remember what I did.

Thanks so much.

Recently, the Firefox browser stopped working. Specifically for me, Costco's website, and Aetna. I believe the issue could be that those websites require that the location is confirmed, but no pop is generated, thus causing the website to not work with Firefox. Please help me, as your browser is the best.

The last update did something to my search bar. I still have it, but when I click on it, it moves to the upper left corner, prevents me from seeing my tabs, bookmarks etc. How can I disable this annoying change? If someone has the answer, I would greatly appreciate it.

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

Late yesterday, all my bookmarks disappeared. Whenever Firefox ask me to update, I do. Please advise if they are stored anywhere from which I can retrieve them. Probably close to a thousand.

https://hbr.org will not allow me to sign in using Firefox. It does not recognise my email address if I use the Lost Password option. MS Edge allows me to sign in to https://hbr.org without problems. I have listed hbr.org as Exceptions in tracking protection, cookies, and blocking pop up windows

For the past month or so, I'd say about 20% of the websites I visit using Firefox just show a blank, white screen. (See allbirds.com site image attached for example.)

1. Cleared the cache and cookies to see if that fixed it. It didn't. 2. Entered Troubleshoot Mode to see if that fixed it. It didn't. 3. Disabled all extensions to see if that fixed it. It didn't. 4. Disabled "recommended performance settings" and hardware acceleration--in combination with some of the above--to see if that fixed it. It didn't. 5. Reinstalled Firefox to see if that fixed it. It didn't. 6. Also paused/disabled VPN (Nord) and anti-virus (McAfee) to see if that made a difference. It didn't.

Any other ideas?

Thanks.

Software is Preventing Firefox From Safely Connecting to This Site

news.google.com is most likely a safe site, but a secure connection could not be established. This issue is caused by Private Internet Access, which is either software on your computer or your network.

What can you do about it?

news.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.

   If your antivirus software includes a feature that scans encrypted connections (often called “web scanning” or “https scanning”), you can disable that feature. If that doesn’t work, you can remove and reinstall the antivirus software.
   If you are on a corporate network, you can contact your IT department.
   If you are not familiar with Private Internet Access, then this could be an attack, and there is nothing you can do to access the site.

Why does Firefox Desktop now completely crash every time I press the Ctrl and cursor keys whilst navigating through text?!!! Very frustrating and I've had to abandon using your app completely. Please fix and redeploy your app as a matter of extreme urgency!!! thanks

If I send mail to curly@stooges.com, it gets put in the curly@stooges.com mailbox -- created if it doesn't exist.

If I get an email from curly@stooges.com, it gets put in the curly@stooges.com mailbox -- created if it doesn't exist. If I reply, the reply gets put in the curly@stooges.com mailbox.

I have one and only one SMTP account. I have 1,000,001 POP accounts. Mailboxes and accounts have no relationship.

This is a serious question, not a joke.

Thanks -- Mark (frozen at version 102.7.1 until a *hit-simple TBird exists).

I have Windows 11 on my Desktop PC and an up to date version of Firefox.

On two separate occasions I attempted to download past statements from two different credit card websites. Both times the requested statement failed to download, or even proceed to the next screen.

I called Customer Service for one of the Credit Cards and was told to try Google Chrome. I was forced to use Google Chrome to successfully download and view the requested statements.

I have been able to download and view the same information from the same websites in the recent past.

Could something have been changed in the Settings or what?

Firefox recently added a feature that requires me to open a new private window to access Revenue Canada. I use Intuit Turbo Tax to file my Income Tax. The Intuit software allows you to download your rax records from CRA and insert the information in your T1 Return. With the latest change to Firefox this option is not available any longer because the default for the CRA account is not to a private window. How do I get around this problem????

I cannot sign into ATT.Net email account on Firefox? I am on Xfinity WiFi.

Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over. I can access using Chrome. How can I access without changing from Firefox?

I'm using Firefox in a kiosk-mode application, on a Raspberry Pi based system, started from a bash script like this:

# Clear history etc. to prevent problems if unit is not perfectly shut down rm -v -r /home/pi/.mozilla/firefox/*.default rm -v -r /home/pi/.mozilla/firefox/*.default-esr rm -v -r /home/pi/.cache/mozilla/firefox/*.default rm -v /home/pi/.mozilla/firefox/profiles.ini

sleep 2

/usr/bin/firefox-esr --kiosk -url http://127.0.0.1

However on booting I get a banner from Mozilla along the top of the screen saying: "Firefox automatically sends some data to Mozilla so that we can improve your experience [Choose what I share]"

This is not acceptable in kiosk mode, as it would give users access to the configuration as well as being a visual annoyance. How can we disable this?
