I've use Firefox vpn for some time now. Suddenly any attempt to access a website, including the lovely link to my kindle book suggested by Firefox results in this: Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

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. message. Firefox is blocking me with no way around??? Regular firefox now just doesn't download! I want to congratulate your implementation of a security nightmare with zero testing. Please tell you product development and marketing folks that they won't have to worry our reading and acting on any of your advertisements!

Hi, The versions of Firefox since Feb 2026 have been extremely memory hungry on Windows 10, even though I have the option to restore tabs on demand set to TRUE in the config.

The memory hungriness has got so bad now that even on my 16GB machine, about once a week I find that my computer has suddenly run out of memory without warning and my entire screen goes black (not just within the Firefox window, the entire screen). When the computer gets into that state I am unable to use Ctrl+Alt+Del to get back to Task Manager, and the only way out is to hard-reset my computer.

This means that whenever I want to do anything else remotely memory hungry, such as running my research code, or a game, or a Zoom meeting, I have to kill Firefox first. But I sometimes even end up with black screen when trying to use Word or Excel alongside Firefox.

Essentially, Firefox is becoming unusable on my desktop, and its bookmark feature is borderline unusable on mobile now since the update a month ago made it impossible to change which folder I save my new mobile bookmarks in.

So if I have two more black screen clashes I think I will give up using Firefox entirely after being loyal to it for about 15 years. This is extremely disappointing.

Hello,

I hope you can help me. My Dell laptop crashed, I had to restart the laptop with a Microsoft recovery key. When I opened Firefox I had to log in again with my password. Firefox told me that the password was wrong, I am not sure if I typed in the Firefox recovery key as well. I changed my Firefox password. When Firefox opened my bookmarks were gone and I can not find backup file when following the Firefox 'import bookmarks' link in the bookmark bar.

Thank you!

OK so, I just updated Firefox to 115.34 Oesr (64-bit) on my Windows 7 Desktop. Before this update, it's been my practice to clear my cookies manually from unknown websites about 3 times a day, only keeping the "exception" cookies. But, since the update, there have been SOOO many cookies...something like 75 to 100 and EACH time I manually clear the cookies...even just minutes after I clear it and refresh the "Settings" page they appear again. And, the worst of it is that Google won't let me sign into Google websites like Play Store and Google.com search saying that "there has been unusual traffic..." and makes me solve capchas all day long. Other sites too say Unusual traffic like CVS and won't let me sign in either. And now, I'm not using a VPN.

I googled the matter and it was said to be was a known issue with the 115 update and the A.I. said to get rid of the ad blocker as a possible fix but, it didn't work. Have Firefox clear cache and cookies but that didn't work, changing "Tracking Protection" to "Standard". Nothing works. Is there an update fixing this issue? By the way, I have had Firefox set to clear cache and cookies upon closing. But the cookies pile up so quickly again. Thanks for your help

Apple cs and Geek Squad both deleted app, reloaded from net, problem remained. Geeks said it was definitely a FF problem and deleted the app completely. I am now using Chrome, which I hate. I want my Foxie back!! I am using Mac Mini, OS Sequoia 15.7.4. I updated to this maybe 2 mo ago? Two upgrades were available and I just randomly picked one. I AM NOT A TECHIE. Please respond in language a dummy can understand. I really need help! Thanks!

bold textEvery time I start the cimpouter I lose my bookmarks how can I avoid this issue. Each time i takes about two hours messing about to get them back

Switched on vertical tabs in the latest Firefox release (149.0.2) and noticed a bit of an annoying issue with the bookmark toolbar. If setted only on new tabs - it push all ui of vertical tabs down, and when you switch - it's going up again. I’ve attached a GIF to show what I mean.

I’ve enabled the option to show the bookmark bar only on new tabs, along with the vertical tabs setting. This behavior doesn’t seem right to me — I’d expect the bookmark bar to sit beside the vertical tab sidebar without shifting it. The current design is pretty frustrating.

Is there any way I can fix this? I think it's a clear bug in UI. Thanks!

Seit kurzem kann man in der WhatsApp-Web-Version keine Bilder mehr einfügen. Es erscheint nur ein schwarzes Feld. In Chrome und anderen ANDROID-Geräten funktioniert das. Nur nicht in Firefox. Die WhatsApp-Hotline schreibt, dass es an Firefox liegt.

I have removed the icon from my toolbar; I have gone into Settings to try and disable the notification; I have tried about:config and switching browser.vpn_promo.enabled to false, and browser.contentblocking.report.hide_vpn_banner to true; I've even turned off my VPN settings on my PC, despite this being browser protection only...nothing is stopping this little pop-up. It is tedious and I would prefer having control over my notifcations, so please help.
