With the latest update of Firefox, my laptop, which is a high end DELL, is experiencing big difficulties just running a Firefox with 3 tabs open. the CPU usage is skyrocketing and it is also heavy on the memory. I am running the same 3 tab on the same websites as I have been doing for the past 6 months, but since the latest Firefox update, this has become impossible. What happened to Firefox? I have had no other significant updates but the Firefox update.

Is there some way to recommend an extension that's available in the Chrome Web Store but not available for Firefox? It's the only one I've found anywhere that does this, particular job.

Beanote will allow a sticky note to be made *anywhere* on a web page -- not in a sidebar -- and it will stay right where you want it. Or you can move it. Also, if there are tabs within a portion of that webpage, it will bleed through transparently to all of them. If you want to add it to another of these tabs, you just click on it and you can move it anywhere you'd like; again, it will stay there.

"Firefox detected a potential security threat and did not continue to www.webmail.ilhawaii.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem."

This problem just occurred for the first time. I contacted the website and they say I need to update the certificate in firefox. How do I do this?

Thank You

Graphics card on old Win7 computer running Firefox died. Unable to render image to screen. Setting up brand new Win10 system and downloaded virgin current Firefox. Have hard drive from old system set up as an external device drive and want to migrate years of bookmarks from old Win7 system on external drive to new Win10 system. Can you please assist?

On many sites, various elements are in a strange font, that I think is "Impact." I have tried a couple things to fix this, but I have not got anything to work. I have noticed that this is only an issue for some elements on every site, and not every single element on every site. My best fix has been to use a "Font Changer" add-on that changes the font of the site back to something readable, but this tends not to work on many embedded webpages and things like that. I am very unsure of what is causing this, or where this font even came from. I have attached an image of a random eBay page where the issue is particularly prevalent, but this happens on most sites.

Thanks in advance for your help! - Benjamin

Up until 2 or 3 weeks ago, I was able to log in. Now I Get "Access Denied". I've tried granting all permissions, cancelling vpn. I can log in if I use Chrome. FRUSTRATING. I like Firefox...

Firefox 111.0.1 (64-bit) Latest update seems to have altered the way the toolbar book marks work. The bookmarks do not display, even though there is a line reserved for them at the top of the window.

I'm becoming less and less likely to customise how firefox works from the default setting, because over time I cannot be certain that these customisations will disappear or become non functional.

Hi,

As the title says, Firefox throws "We can’t connect to the server at m.imdb.com." error every time I try to open a page while everything else works like Chrome, Edge and when I ping via command prompt I get replies and other applications. (Win 10 64-bit with latest Firefox)

I think it's a system-wide problem but I can't figure out where. I was under the impression that it's a DNS problem but it doesn't even open IP addresses like 192.168.1.1 and it doesn't open instantly, no matter it's Google.com or my router IP, instant error message.

I tried everything I could find which are:

• Refresh, clean re-install with deleting profile directory
• clearing cache and data
• Toggling these in about:config: network.http.http3.enabled, network.dns.disableIPv6, network.dns.disablePrefetch
• Enabling/disabling my adapter
• Running a couple commands:

   ipconfig /flushdns
   ipconfig /registerdns
   ipconfig /release
   ipconfig /renew

   netsh int ip reset resetlog.txt
   netsh winsock reset catalog
   netsh int ipv4 reset reset.log
   netsh int ipv6 reset reset.log

• Setting proxy to None
• Restarting with Troubleshoot Mode (add-ons disabled)
• Removing Firefox entry from Windows Firewall. (I haven't installed any Firewall and Anti-Virus)
• WIndows's Network Reset
• Rebooting machine and router

I'm sure there are more, these are all I can remember now.

This happened some months ago but can't seem to remember how I fixed it.

The only way it opens sites is with a VPN that sets a system proxy and setting Firefox's proxy to "Use System Proxy Settings".

Cheers

Hi, I use Cambridgeone.org materials to teach English online. Never had a problem. Taught last Thursday using Firefox 110.0.1 and digital texbook on Cambridgeone website.

Installed update to Firebox 111.0.1 the next morning. Now the full teacher's toolbar on the textbook doesn't load. (see image) It does on my desktop app (see image).

What can I do? Have cleared all caches, run disk cleanup, even disabled Privacy Badger without effect.

"Open previous windows and tabs on startup" doesn't seem to work for me - I check off the right box in Settings. (see attached file) but it doesn't work. I use Firefox as a dedicated app for one project, so would like it to open right at the four pages I always use.

Odd, because this USED to work, but has stopped doing so in the last week.

Laptop using Windows 11 64.

I downloaded the newest version, also signed in and out, but no help.

Thanks.

10 days ago firefox downloaded a new version. I thought I was selecting an update, but I got a Second version of Firefox. After backing up bookmarks, I deleted all of them and put another "new" version 64 bit. The website/search bar used to be on the menu Bar which I keep open all the time. These were at the top of the window. I also had a search bar at top, all the way to the right as facing it. NOW I can't seem to get the website input off the Bookmark toolbar and up to the top. I was able to get the separate search input box? What am I overlooking and I am think there is something easy I am missing. Pictures or a description of steps is helpful; I can't find a solution. MOZILLA didn't restrict placing this website box on the top menu bar, did they?

Thanks. Picture of browser is attached.

'bold textpr end of file error, pages will not load have to constantly press retry. mostly in email and home page. I have reloaded deleted and reloaded still the same things '

Updated to latest Firefox, 111.0.1 64 bit. Browser is now extremely slow to load. Hangs up on some web sites. Lots of little blue time out circles. Almost unusable. Have to reboot to get the browser to load.

Since firefox's latest update I am unable to access my online PNC banking account. PNC says that Firefox is no longer compatible with their online banking system. I'm using an IMAC computer. Does anyone know what's causing the problem or am I being forced to use a different browser ? My e-mail address is[email removed from public] Thank You
