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

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'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

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!

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

Can someone help please: - I've been trying to buy some tickets for an event in France. When I access the following from Firefox (140.6.0esr (64-bit)) on Debian GNU/Linux 13 (trixie)) the ticketing purchase options don't show. When I access it from Chrome on Android or Edge on Windows it does show. https://www.circuitdesremparts.com/prochaine-edition/billetterie/ It seems I've now missed any Tribune tickets.

Thanks, Tim

Accessing Planefinder.com. Have done so many times. After checking on a flight multiple times today, I acquired a notice that said I was blocked from accessing. Is this a scam? It says I entered a word or phrase that was unacceptable and thus am blocked. I can still use Planefinder on my cell phone. I only enter the plane information that is called for. What is going on?

Your article about the expiration of Windows 10 says that anyone that has FireFox on the Release Channel doesn't have to worry, that updates will continue to support Windows 10. I don't know what that means (Release Channel). And how can I check if that's what I have?

When I try to log in to my account with Amazon Prime, Firefox freezes as soon as I hit the Continue button after entering the username and password. I can't open or close tabs or do anything. I don't have this problem with the Amazon account in any other browser.

Any ideas why this happens and how to fix it?

My credit card payment methods are missing from Firefox's settings. I tried enabling every relevant setting in about:config and still they won't appear. My current relevant settings are shown in the attached screenshot. any suggestions?

The last 2 days i have had problems signing into my Aliexpress account. The site has told me it is temporarily unavailable, then that the server is taking too long and now that parental controls have been used.

I am 68. I don't need or use my computer for sites that require parental control.
