Diễn đàn hỗ trợ Firefox

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

When accessing important accounts on websites, like financial websites, I've always heard you should close your browser when you're done with the secure website. If you log on in a PRIVATE window and close the private window afterword but leave the main FireFox window open, is that the same thing? I think it is and the private window will delete any login or activity info as if you closed the browser, I just want to confirm with someone more knowledgeable before I make a bad assumption. It also seems to have the added benefit of deleting anything you might download and save elsewhere from the download folder so you don't have to delete it from the DL folder and then the recycle bin. Seems like it's good practice to use the private window this way. Again, just looking for a 2nd opinion.

Thanks,

I recovered my account using a backup code and set a new password. Two-step authentication is enabled but I don’t have the linked TOTP app. The settings UI does not allow disabling 2FA and does not offer backup code input. I still have unused 10-character backup recovery codes. Please advise.

My emails used to display in date order but since a Mozilla upgrade they are now grouped as Today, Yesterday and Last Week. Is there a setting to alter this back to one list in date order please?

First I tried all the suggestions I could find. And FF just kept double filling the password. So I did a completely fresh FF install to a separate folder with no cookies or passwords or anything saved, and never any extensions installed. Still double fills the password -- which makes it impossible to log in. I am using FF Portable, and tried both the latest version and an older version. What could possibly be doing this?

I have a new Mozilla (FireFox) account and keep getting emails that say I need to confirm it. They include a button to do so but I'm not clicking it unless I get better information from you. Please help. The email swears my account will be deleted if I don't confirm it. What do I do?

I am just burned out with Firefox and not sure why I should continue to use it instead of some fork or Chromium-based browser.

It seems like every update brings some new GenAI/LLM component that is auto-enabled and difficult to disable. I do not want GenAI/LLMs in my web browser. I have dropped nearly every other application or software that has forced it on me and included it in their product. I feel like I'm trying manage a Windows system having to follow blogs to debloat, restore privacy, and restore security. GenAI/LLMs shouldn't be in my web browser. And, they should be opt-in, not opt-out in some confusing mix of GUI and about:config madness. If GenAI/LLM is so great, then make it an extension or a fork then let those folks use it from there. Don't bake it into the web browser.

I continue to use Firefox for uBlock Origin but I guess that would be possible with a Firefox-fork. However, I am just tired of having to continuously manage my Firefox browser and battle websites that only support Chromium-based browsers. If Firefox actually seemed intent on improving security and privacy then I could find the motivation but this GenAI/LLM nonsense seems the point of no return.

On my Android phone, I've switched to a Chromium-based browser given the poor state of security and hardening for the vanilla Firefox. I keep IronFox on hand but it is just easier to surf the web with a Chromium-based browser due to many websites just working better. Why should I deal with the pain and frustration of limited Firefox support when Firefox isn't even keeping up with security hardening?

As for desktop, the Firefox browser just doesn't seem as snappy or stable as I would expect. Firefox for Linux is still not supported for Slack Huddles. How is it 2026 and Mozilla/Firefox are still not fully functional with one of the major business chat platforms? Yes, I know this primarily a Slack and AWS-Chime-SDK problem but it is also a Firefox problem because there isn't much that a user can do. I've tried to prod Slack and the AWS teams numerous times to support Firefox but they've just done nothing. I also see nothing being done by the Firefox team, too.

Another example is the EdgeSuite CDN. Nearly always they block my traffic when I use Firefox. Switch to a Chromium-based browser and EdgeSuite is much less likely to block me. This is fairly consistent for the retail and financial institutions I use.

As far as I am aware, many of the security concerns brought up by Madaidan in 2022 still hold true for Firefox today, especially for Android and Linux. If this is no longer true, then it might be good for the Firefox team to post a rebuttal or update clarifying the current state of Firefox. The average users such as myself only see the Madaidan blog post and have to take it at face value. https://madaidans-insecurities.github.io/firefox-chromium.html

Anyway, I don't see a way ahead for me and Firefox but maybe you can convince me. It just seems like Firefox and Mozilla have lost their way. They no longer seem focused on security and privacy. Instead they're forcing privacy, security, and system resource disasters onto their userbases, just like Microsoft, Google, and every one of the major tech firms. I just don't see why I should use, promote, and even support Firefox going into 2026.

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

When I try to access a function of my banks website I get the message: Authorization has been denied for this request

Late last year this occurred when using FireFox but not Chome or Edge. I have contacted my bank and was told I need to add an exception to the Manage Exceptions list. I did that and I was able to access that function of the site. Now the error is occurring again. This time I figured out what the URL was that needed be added. All other functions of the site work fine without these exceptions.

My question is: what are the security ramifications of this and what do I tell my bank so they fix this? Does this make their site less or more secure? Is it necessary to fix this?

Windows 11; FF 146.0.1. All updates installed.

I am 82 years of age and did not grow up with the Internet. I have a total of only 8 hours of training on a PC. I have no idea how my PC got into 'safe mode' and now all of my extensions are disabled. I do not know how to exit 'safe mode' to allow the extensions to be enabled again. I tried following the instructions as provided, but to no avail.

I have never ever had a problem getting into my bank account until this evening.

Says it is insecure.

How can this happen? I really need to get into my account!

Hi,

I use the Page Info window quite regularly, it used to be accessible via the right-click menu but this seems to have been removed in recent updates. I can still access it via Ctrl+I, but this isn't as convenient as using the menu.

Could you please tell me how I can put this useful feature onto the menu / toolbar as a shortcut?

Thanks

Owen.

Hello Our town had two unexpected electrical outages during severe thunderstorms a few days ago. When I reopened Firefox and tried to log on to my outlook account, I received the following message: UTC Date: 2026-01-10T07:45:12.961Z Client Id: 6ACCBE246D464180895379C1XXXXXXXXX Session Id: d6e32139-5adc-4e94-b1e6-ff2b299c8f50 Client Version: 20251212003.10 BootResult: 2152857611 Back Filled Errors: None err: NS_ERROR_FILE_CORRUPTED: esrc: Preboot et: ClientError estack: getItem@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:21149 i@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:7:141360 importExistingCache@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:23004 946909/i/<@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:7:151863 initialize@https://res.public.onecdn.static.microsoft/owamail/hashed-v1/scripts/owa.94868.m.b71f002c.js:1:21016

I can open my email logins in Chrome and Safari, but not in Firefox. In Firefox I can open all my previous Bookmarks, but not Outlook. Any advice gratefully received, thank you

For some strange reason, I get this response when logging in to local newspaper on Firefox..image one. When loading the same newspaper on Edge, I see this instead...image two. I've been in contact with the newspaper but the techs there can't figure what's happening. Is there a setting I have wrong on Firefox? Thanks for your time.
