I am using Firefox as my default browser and today I find out that, as I was using Google ads to set up a campaign, and trying to see previews of my ads, Firefox was strongly lagging or sometimes I had to force it to close. Afterwards I used safari and everything was ok. It is useful to mention that I had dis-activated the ad blocker on Firefox. I use 136.0.2 edition and Mac 15.3.2.

Hi there! It started yesterday. I keep getting warning messages from Bitdefender that a connection Firefox was trying to establish was blocked. I will include a screenshot of the warning. I searched the link included in the warning and it comes up as a Firefox related link. I had six or seven of these warnings within the last 3 hours of using the computer and am concerned and irritated. Firefox is updated automatically on this computer and I think the last major change would have been the "cookie jar" thing(?). Obviously, the warning only says that the a certificate has expired. Thank you in advance for your help. Yours sincerely,R.

I am in college at CU Boulder. In order for me to view my recorded classes my browser needs for me to allow 3rd party cookies. your browser is blocking them and not giving me an option to unblock them. How do i fix this problem?

Hello fellow foxes,

I really need to use Firefox version 52ESR.MSI as I need to push it through Active Directory.

I have tried downloading the version from https://ftp.mozilla.org/pub/firefox/releases/52.0.1esr/ ,however there is no MSI version that I can see.

I also tried downloading from https://www.mozilla.org/en-US/firefox/all/desktop-esr/win64-msi/en-US/ but the last version is 115.

I also tried third party sites like oldversion.com but I couldn't find it.

Is there anyway I can get this version of firefox? It's really important to me.

Thanks in advance

I tried all common troubleshooting steps: deleting cache reinstalling different settings turning off adblocker/vpn disabled efficiency in task manager and set it permanently to off in FF

I used to have 1000+ tabs in 2016 no issue. I had problem in past with Firefox using 100% CPU which now it is not using only like 50, but memory is getting full 89% i use also large page file on ssd. Problem is even when i restart firefox it is slow with low RAM usage! SO that's not it! Even 5 tabs sometimes it is slow!

It is so damn slow it drives me crazy! I tried also Quantum in past when Firefox has 100% CPU usage bug and it was only tiny bit better but still caused 100% CPU usage!

All other browsers are anti user cannot even stop Autoplay literal terrorist Firefox is only normal browser unfortunately performance compare to 2016 got absolutely abysmal! I had this problem even in-between reinstals of OS so it doesn't seem it is me. I play demanding games no issues on my PC...

'm not a programmer, but the almost daily new versions of Firefox that you publish make me question whether you know what you're doing? It's a shame to have a product that needs so many constant fixes. I've been using Firefox almost since the beginning, ie 20 years, but I'm seriously considering trying Opera or another browser that doesn't offer a new version every day.

This is from User: Paul C. I have posted about this issue before. Last week!

This problem has returned after the clean installation of Firefox again and Firefox did more auto-updates. See attached files from the search bar "Information con(circle with the letter i inside) says I do not have a secure connection! I am not choosing to have an insecure connection. I rely on my ISP, Firefox, Windows Defender, and my VPN to make sure I have a connection that is safe!

Hello. In the past two days I lose my tabs when I shut down Firefox. I used to be fine using the X at the top right and when I restarted the browser, all my tabs would still be there. Then they started going missing, so I started using the menu option to exit the browser. The tabs still went missing.

Then I noticed the square icon button on the extreme left and have discovered that Firefox has different windows, and that one of them (see attached image) has all my tabs in it, while the current window does not.

I cannot change Window 2 to be the current window. There is no obvious function on the page, nothing in settings and google is useless - I just get pages of discussion of how to tab between different apps on the desktop.

How do I make Window 2 the current window? See image.

Thank you

This is a weird one and I'm hoping there's a reassuring explanation.

I had Firefox and Sumatra PDF open, nothing else on Win 10.

I switched from Sumatra to Firefox (1 tab open), searched for something, and Firefox froze, and after a while Windows gave me an option to terminate the non-responsive program, which I did, and Firefox closed.

But the hard disk was active 100% afterwards, and everything slowed to a crawl, and I couldn't even get the Task Manager to open, so I did what I haven't done in many ages, killed the power. (Experience tells me a memory leak.)

After the restart Firefox opened, a bit slowly, to the last open tab. Browsed a bit. All is fine. Closed Firefox, opened it again, and now I'm logged out of every website, including the saved preferences, e.g. of Wikipedia.

It's worth pointing out that I closed Sumatra just fine, but it too lost the history (it remembers which page I last viewed for the opened documents).

Since Firefox was the one to freeze, and to work fine afterwards, logged in and all, then lose all after opening it again, I'm not sure what happened, and if there's anything I can do.

Sorry for the lengthy post, but basically:

Is that expected after a freeze/recovery?
