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, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!

Hello. I installed the add on Tranquility Reader, found I did not like it, and uninstalled it. I have restarted my Firefox, as well as my PC, several times, but I still do not have graphics back like they were before. Am I missing something? Or has my whole system just gone on to another world??? So Aggravated! TIA Christie

Chase website now requires Mozilla Firefox update 128 or higher to access accounts. My version says my version (115.30) is latest update. Do I need to find a different browser or is there a solution? I am using Windows 7 Pro desktop. Thank you.

Firefox show's my location when 'Googling'

In 'about:config' I have my geo set to disable, I tried it enabled and turning it back, also in 'Settings' Location shows empty and I can not get it to see Google nor can I manually insert it.

Any idea what is going on please??

So i was going to go to the forums to whine about the new phone layout (cause it's ugly, less compact and laggy to the point of freezing) but the forums seem to be down rights now.

i looked up lots questions and solution. nothings seems to work. i did all Troubleshoot and diagnose Firefox problems. cleared cache, restarted firefox, refreshed. everything I could do. nothing works.

could you tell me what else I can try?

Rebuilt my computer, restored Bookmarks from 'bookmarks-2025-08-30.html' but the original 'Other bookmarks' (just below 'Bookmarks toolbar') is now empty and has been moved to the bottom of all my other bookmarks in a new 'Other Bookmarks' folder. How do I get the contents back in the 'Other bookmarks' (just below 'Bookmarks toolbar'). P.S. I have a backed up 'bookmarks-2025-08-30.json' as well as a ' bookmarks-2025-08-30.html' available, if that would help. Regards and Best, NP_145

After watching this video https://www.youtube.com/watch?v=mAfY_bNJTBI i went to https://www.cloudflare.com/ssl/encrypted-sni/ and did the test. Result is 3/4. (See screenshot below) Secure DNS, check DNSSEC, check TLS 1.3 check Enrypted SNI, fail In Firefox i tried doing exactly what the person did in the video but i dont have the settings he is showing in about:config Why is that? (Below you can see the screenshot, those settings are missing from about:config)

So my question reamins simple, how can i enable Enrypted SNI in Firefox?

Hello,

It was good to see on today's (2nd June '26) flyer that I can get the free Firefox VPN, excellent for my laptop. I took my previous one off because it was clogging everything up.

I am from the UK and living in Spain. I have recently bought a Firestick but cannot get any UK programmes due to regional restrictions, so I need a VPN to get round those.

Proton VPN offer a free service that I can put on to the Firestick. Their site gives you the instructions. My question therefore is, can I put the Firefox VPN onto the Firestick and if so, how? It makes sense to have all your VPNs in one place. Kind regards Mike

Just over a week ago, I found that a particular page transition always crashed by browser tab (i.e. a reproducible crash). This occurred on the Quora.com website when visiting the 'Questions' tab for any Quora Space. I am not aware of anything special associated with this operation, and it works OK in Chrome. There may be other cases -- outside of that particular website -- but that is the one most affecting me at the moment.

There are no associated Windows events logged. I checked about:crashes and the Crash Report folder but i cannot find any readable details.

If I refresh the page then the transition occurs without problem.

I would like to find the cause myself because I am on an Windows 7 64-bit ESR version, although I do not believe this is an ESR issue as it was working fine a couple of weeks ago. it is just that I cannot find any logged information on the cause.

The site chatgpt.com demands challenges.cloudflare.com to be allowed. I visited this site and allowed cookies. Then it worked. However, the chatgpt.com site froze and when I reloaded it, I had to start all over again. This time, the request for challenges.cloudflare.com remains, even though a URL attachment is reloaded every few seconds. The same thing happens on the openai.com site and several other. I'm using windows 7.1 and ESET Smart Security Premium.
