Firefox Community Forum

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.

every time I enter some words for a search the system blocks access with an "I'm Not A Robot" process. while I always get past this it is annoying and has only started happening in the last few days.

I've been using Fire Fox for decades, but lately it is so slow, I thought there was something wrong with my Windows 7 ultimate. I've done full Windows reboot, to no avail. Then I see the internet t hat FireFox is starting to implement AI. I thought that may be the issue, but after looking into it, looks like that isn't an option with my old Win 7 OS. So if that isn't the problem, how can I find out what is bogging Fire Fox down? I keep a watch on my CPU usage, and the usage is going nearly to 100%, when it used to barely go over 10%. When I check the actual CPU usage, it shows as many as 15 or more items tied to Fire Fox.

Is this all a result of continued use of Win 7? I'm planning to move to Linux, but that will take me some serious time and effort. Gerald

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.

I have spent hours with Tech department and digital assistand department at Directv. Today they are telling me as long as I use Firefox I will be unable to access my account. I have paid to have my computer checked out and was told that it was updated and the system was working fine. How to I get Directv to recognize my system?

Just updated my MacBook Air to Sequoia 15.7.3. Since that update, Foxfire will open, but when trying to open an article in Foxfire, Foxfire locks up and doesn't wan to shut down even with "force quit." What can I do?

I've used Firefox for 20 years through the various iterations of Windows, and have been using it trouble free on Windows 11 since November 2024. Two days ago, however, When I tried to open the Guardian site (www.theguardian.com) it would open very slowly and not load and of the pictures. This gradually got worse, the site taking for ever to open at all, and always with the little dot in the tab at the top left going from side to side showing it was still loading. I have tried everything I can think of. Opened in troubleshoot mode, changed DNS settings, uninstalled and reinstalled Firefox twice (one time to see if it would work normally if I didn't actually sign in to my account). All to no avail. In fact now things are worse, in that the GOV.Uk website is now giving me similar problems - and a few other sites have become slightly slow and reluctant to open as well. My internet connection seems fine, and all these sites open without any trouble on Microsoft Edge. I am NOT very good at tech, and I am now tearing my heair out as to what I can try next.

Any help wopuld be gratefully received!
