I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

Why when you click on the extensions button (jigsaw puzzle icon) in the toolbar to open the extensions panel the “Personalize Your Firefox” screen appears ???

When you right click a gear icon in a particular extension, the drop down menu has no "pin to tool bar" option, it only shows "copy/select all/print..." options ???

Thnak you.

Why am I getting this message, when trying to save to pockets: It looks like you were misusing this feature by going too fast. You’ve been temporarily blocked from using it. Back

Okay, 2 of my financial accounts are not available when using Mozilla VPN. What I get is an internet error message like this: "" Access Denied: You don't have permission to access "http://raymondjames.com/" on this server.

Do you know the technical reasons for this? And can you recommend anything I can do about it? Yes, this is the latest Mozilla VPN and Firefox 151.0.2 versions on my older Win 10 desktop.

Yahoo Mail won't open. Saved Yahoo Mail at bottom of page says "No internet connection" but work even though other apps and bookmarks open and recent Yahoo Mail saved at bottom of page opens when I click on it. Have most recent version Version 115.18.0esr 64-bit? Restarted Firefox but still won't open Yahoo mail bookmark.

Why are there 20 to 30 instances of firefox in my task manager when I have just 2 tabs open? It is bogging down my old laptop. I got directions to fix it from Mozilla Support, by turning off recommended performance settings and lowering content limit from 8 to 4 [although directions said I could do that right there, but I couldn't and had to go to config.] After a restart, I currently have just one tab, and there's 12 firefox, and it had gone up over 30 originally. I did a whole bunch of end tasks, but they keep coming back. Why can't I force it to only open 1 firefox for each tab? I don't want all that extra crap!

The menu bar keeps flashing about every 5-10 seconds. When it does it disrupts / interrupts whatever I'm typing, deleting everything I've typed when the flash occurs.

It also disrupts things like using a drop down menu. The menu is opened (aka dropped down) but when the flash occurs it collapses the drop down menu.

Also for example en typing; let's say I'm typing " Mary had a little lamb". After typing "Mary had a" the Menu bar flashes. When it does "Mary had a" gets deleted. As I continue to type not knowing "Mary had a" was deleted I look up and see all that's left is "little lamb".

It's constantly doing this even while typing this message / question.

If copy and pasting it'll clear the text I've chosen to copy so I have to go back and re-select it. And try to get it done quickly before the next flash occurs. But if the next flash occurs the same thing happens all over again.

I have no idea what's going on. Searched and searched and can't find anything. It's making Firefox almost impossible to use. Please help me?!

I'm using Firefox version 115.18.0esr It is up to date.

Today: DevTools crashed many times, and I’m facing unusual issues. I cannot call through Messenger and cannot connect for video calls. Also, DevTools is not working, even though Firefox Developer Edition is quite good and healthy. Even Firefox is not working well. Please fix this issue quickly.

OLD ISSUE

My Firefox is using a lot of data; I don’t know why.

I am not using Firefox, and it is not running in the background, yet it is always using the internet. So what do I need to do in this situation? I tried to stop the internet connection using outbound rules, but it did not work. It is still using the internet. What is the reason my browser has high data usage? I have high data usage; in fact, in the past 12 days, we've used 30+ GB of data.

The comment sections for foxnews.com and other sites disappeared using Firefox but not when I switched to Chrome. This just happened 6-18-25. Before this date, it worked on Firefox.

Hey all. I am having some connection issues with my secondary comp. Firefox 132.0.2

I recently moved and am getting my home office set back up. Nothing was changed during the move other than shutting down, unhooking everything and setting it back up at the new home. My secondary comp is used for live streaming various TV channels, Youtube, live radio broadcasts etc. Youtube, Google and Gmail loads and works fine. Several of the TV channels load the page but will not stream. Rumble, the two radio stations I listen to and our website host access page all give me the Server Not Found screen. It also fails to update Firefox. Also, my Thunderbird will not download new emails. Now here is the weird part. I can go to all of these sites on my main comp and everything loads and works fine. Any ideas? I have tried changing different settings but nothing makes any difference. I even disabled the firewall.

Thanks.

Recently I'm having an issue with Firefox that makes it so when I try to open it, it simply refuses to do so. Say on my desktop I double click the icon it will open for a split second and then instantly close and refuse to do anything afterwards. This is very frustrating, and I haven't yet discovered a solution and would really like to be able to use Firefox again. What is really strange is that this is a persistent problem not only on my laptop but at my pc as well which are two separate devices. If anybody can help or has experience with this problem to offer incite it would deeply be appreciated.

Since the last update its a mess. My advisors are telling me its loading slow I cannot connect with them in their chat............Chrome is fine

Can someone figure this out?

Thanks

Although I have successfully logged in many times, I get an error message today: An error occurred during a connection to b2clogin.firstenergycorp.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

I asked this a year ago and never saw a solution (other than 'gee, it should work yet'.) I use the local Windows Hosts file to give my router a quick reference name to get into it. That too has worked for years but began to fail last year. Inconvenient. The best I could track this down, it has something to do with forced DNS lookups and skipping the old Hosts file. If so, any work around to get my system simplicity back? Attached is what I see on each attempt.

I tried various settings for DOH and nothing works. I can reference the Hosts file in a Windows Cmd Prompt and it resolves just fine. Something is screwy in Firefox for some time now and I'd like to know what.

Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox

My very favorite browser will not open when I click the FF icon. I did another download and it will not open, as well. What can you tell me about this issue and how to fix it? An avid user for many years.
