Diễn đàn hỗ trợ Firefox

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

I have Firefox running on 3 machines, only one of them is synced to my Firefox account, so that means that I am not running the same addons on all of them. I have Firefox running on Windows 10 and the two other are running on Windows 11. From time to time, I notice that Firefox is running slow and its unable to open normal websites like facebook, instagram, youtube, or any other website that I normally browse, and when I check the Task Manager I can notice one unusual exe running named "crashhelper.exe" which is located in the Firefox installation directory and its signed by Mozilla. Once I kill this task Firefox continues working as nothing happened. This is happening since the last update which was few weeks ago (if I remember correctly). What is this app doing and why it is making Firefox stop opening websites?

8 out of 10 times that i try to connect to the following site:

https://www.tax.ny.gov/online/

I get the following error message:

Secure Connection Failed

An error occurred during a connection to otc.tax.ny.gov. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Now and then, I'm able to log in successfully. lately though, I'm having trouble logging in using Firefox browser.

This is becoming very frustrating. What could be the issue? What do i need to do to resolve the problem?

Hello,

I just closed FF (latest version) and opened it again and all my tabs are gone. I had a private FF window open, so I am guessing this is the cause.

Is there a way to get get them back?

Thanks

I am interested in Firefox View, but I do not see that button on my toolbar (see attached image). When I search extensions I don't see that come up as an option. How do I add Firefox View?

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

Why it disappeared? It was always there. I am logged in Pocket and tried to restart Firefox. Maybe it has to something do with recently added AI side panel? It seems that since then my Pocket icon is missing. Browser version: 140.0.2 (64-bit) OS: Linux Mint MATE 21.3 (Virginia) Kernel: 5.15.0-143-generic

Next to the field where a current HTTP:// is entered, there USED TO BE a button allowing me to add another empty search page. Than has vanished. How do I restore it please?

Hi, can someone please to me how to turn off automatic updates on Firefox Version 140.0 (64-bit)? Firefox's own support page, "https://support.mozilla.org/en-US/kb/firefox-options-preferences-and-settings?as=u&utm_source=inproduct", is incorrect. It states that, "Firefox Updates Here you can check your update history or change update settings for Firefox.", but you can not change the update setting, (see attachment).

It is really annoying it updates while you are using it, ruining your experience as you can no longer refresh tabs or open new ones forcing you to restart it.

Like the title says.

I used to have a Pocket icon. Yes, I know it's going away.

I'd like to use the TenTabs icon. Where is it?

And if you tell me it's on the "Customize Toolbar", I can tell you that, no, it is not.

Help?

Audio Equalizer and Amplifier(https://addons.mozilla.org/ru/firefox/addon/audio-equalizer-and-amplifier/) extension on Yandex Music(https://music.yandex.ru/) doesn't work, which was noticed only in Firefox. In other browsers, it worked correctly and without any problems, I don't understand what the problem is. PC rebooted, browser restarted, the extension uninstalled and installed again. How can this be fixed? The extension worked correctly in Chrome and Edge.

Hi. I used to be able to just grab and image on a webpage and drag it to my desktop. Now I have to go through the whole rigmaroll of right click and save. Anyone know how I can go back to the faster way please?

Thanks.

It's really strange (I'm still trying to understand my relatively new Windows 11 laptop), bookmarks have been where I'd expect them for a few days, then this morning, it's as if Firefox has done some sort of clean/re-arrangement. The bookmarks had disappeared and there wasn't my usual array of sites available along the top. Then by clicking on a few things on the right (Firefox) 'most used' re-appeared, then later the toolbar is there on the right, I'd really like it back on the left And also I'd love to know whether I might have done something unconsciously which caused this.

I was trying to setup 2FA on my Mozilla account on Firefox pc browser (140 version). The process completes without issues with Aegis authenticator app, I download the backup codes and I even get the email confirming the recovery phone number was added. On the Mozilla accounts page 2FA turns to enabled. (I'm on Windows11 with latest Firefox browser version)

However after a simple refresh, it turns back to disabled. I repeated the process and same thing happens. Same even on Firefox Android. What could be the issue here?

I was planning to start using the AI chatbot sidebar finally, tried out all of the free options available and settled on HuggingChat. The very next day, HuggingChat ceased operations. I don't really like the other preset options, but I have a couple of other models that I would be interested in trying out. Is there some way to add a different model than the five preset or am I just out of luck?

Firefox crashed and I cannot recover my tabs from history. I click on restore all tabs and it does nothing. The tabs I was hoping to recover do not even appear in my history either.
