Firefox Support Forum

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

I normally use Firefox Beta. Ever since upgrading to v92 the option to Send Tab to Device has been missing when I right-click on a tab. I've downloaded other versions of Firefox and the issue seems to follow me out of Beta and into the regular release. I've seen other people having issues with syncing and sending tabs between devices as of late, but no one seemed to be completely missing the option to do so.

Whenever I use Firefox, I have an issue once a day where the browser freezes momentarily, flickers, blacks out tabs and other portions of the browser/text, and then resumes. I have had this issue since Day 1, and no amount of Windows updates + Firefox updates has resolved this.

This also occurred when I was using stable versions of Firefox ARM64.

Specs: Firefox ARM 92.0b8 64-bit Surface Pro X 2 (2020) OS: Windows 10 Pro v21H1, Build 19043.1165

Attached is a screenshot of what it usually looks like when this occurs. Please advise.

If I copy and paste any two words or more into the search bar on the new tab it goes to google.co.uk as that is set but only searches for the phrase minus the first word. If I paste it into the address bar everything is ok. If I do the same with a one word term the search bar does nothing having "lost" that word and the address bar works fine.

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX.

menupopup > menuitem, menupopup > menu {
  padding-block: 4px !important;
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

EX:

menupopup > menuitem, menupopup > menu {
  padding-block: 0px !important;
}
:root {
  --arrowpanel-menuitem-padding: 0px 0px !important;
}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

No matter what I try, I can't login to tumblr on firefox - it works fine on other browsers, but not firefox. It keeps giving me the

Message. I have tried removing antivirus extentions from the browser that might change the URL and adding Tumblr to the exclusions list on my computer's main antivirus program and it still doesn't work. What can I do to stop getting this error?

I am having an issue every 5 minutes where firefox will not load any pages it essential makes me stuck on the page. I have to than clear my cache for it to work again only to have the issue again a couple of minutes later. I have refreshed firefox 4 different times, uninstalled 3 times to no but nothing seems to work.

On most of the websites I am visiting including gmail. ..where ever there is a login page, it shows a blank password field even after or while typing the password.. but it is logging in... show password option works in some instances. But this has been happening after the last few browser update was made.. 2-3 version ago I believe. Works ok in safe mode. Does not also show saved passwords if already saved.

I know I am not the first person to complain about this. The spacing/padding between menu items, in particular the Bookmark menu is just ridiculously large. It got even bigger in 92.0!

I rely on Bookmarks heavily and use hundreds. I guess this was done for touch screens? The main interface is still currently the mouse for computers.

I see the only current fix is a using a stylesheet and it seems a bit involved. I have to give it a try. I am pleading with the designers, please give us the option to use compact padding once again. I am not sure why this is being forced on us. I really like Firefox, please don't make me look for another option. Thanks!

I tried sending a friend of mine an audio message on FB messenger (in firefox 92, updated yesterday), on Windows 7. Facebook tells me it needs permission (see image). I've tried everything I can find about this. The Firefox page-info permissions is now set to "ALLOW" although it was set to use default (ALWAYS ASK). It just doesn't work. In the regular settings for microphone, it will NOT ALLOW me to add the website and apparently, FB is NOT asking for permission, because the entire dialog is EMPTY.

Hello,

Today I allowed FF to upgrade to 92.0 (64-bit). I do a lot of work at Ancestry.com and notice that every time I open or refresh a page I get a pop-up message that says "It looks like you have local storage disabled. While you'll still be able to use the site, you may notice that pages load more slowly. Fix the issue."

I followed the Fix the issue link. It took me to a page that said I needed to allow cookies. I do have the cookies enabled.

Any Idea how to fix this?

Thank you in advance for your help!!

Part of my morning chores is the printing (and databasing) of some of today's news as available on the Internet. I use Win2Pdf as my printer and have never had problems. Over the past couple of days FF has printed one webpage okay but it hangs when moving to preview on any subsequent webpage. Rebooting FF is the only solution I have found but the new boot only prints the one webpage and hangs on subsequent pages. This means that I have to reboot FF every time I want to print a webpage - something of a PITA.

I have re-installed FF (92.0 64-bit) and run through the troubleshooting options. No improvement.

What's the hangup? How do I fix it?

There is no messages or something, it just hangs (all tabs and Firefox open windows). There is no report bug options in Firefox, I cleared my cookies and data (the same), it's stops responding on clicking top right green button (log in) on https://www.privat24.ua/ or https://next.privat24.ua/ when window asking for phone number appears. Tried troubleshoot mode and disabling add-ons (I have only 3) - result is the same.

I use the 'Edit/Find in Page' (Cntl + F) to look for something on a web page and, once I find it, I turn if by re-entering Cntl + F. This no longer works the same on my FireFox. Cntl + F still turns on the search bar. But I can't find anything to turn it off. I have tried 'Cntl + F', 'Edit/Find in Page', and there is no 'x' to close the bar. How do I close the Find bar?

Thank you

Hello,

I am using Firefox version 92. The screenshot function is not working, both if I right click and request a screenshot from the slideout menu, and if I request a screenshot from the shortcuts/overflow menu (scissors icon). I have attached a screenshot (taken with ‘prntscr” through windows) png of the result that takes place on my screen. The screen will freeze with this image of a large X until I do a refresh of the page. Cntl-Shift-S also does not work. I have tried clearing the cache, running FF in safe mode, refreshing FF, reinstalling FF, and I have ensured that the extensions.screenshots.disabled setting in about:config is set to ‘false’ (also toggled it to ‘true’ and back to ‘false’). I have attached a screenshot of all the settings in about:config that pertain to screenshots.

Thank you for your help.

Firefox Browser uprated to 92.0 today. Previously whilst browsing Ad's were showing; today I have no Ad's displayed but have not enabled an Ad Blocker on Firefox. A site I use extensively cannot now be properly viewed; I get a message to turn off Ad Blocker. I have set Enhanced Tracking Protection to 'Off' but am still unable to obtain full functionality, I am using standard Firefox Privacy settings otherwise. I am able to browse the site properly using MS Edge. I have deliberately refrained from using any AD Blocking on my part so as to ensure the site in question can be properly viewed. The only Firefox extension being used is Kaspersky Protection; I get the turn off Ad Blocker message both when Kaspersky Protection is on or off.

Each morning, when I first cold boot my computer, the moment I open my Firefox browser, I receive numerous (10+) identical error messages from Bitdefender:

Suspicious connection blocked: Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to content-signature-2.cdn.mozilla.net. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Question: Is this ACTUALLY coming from Firefox? If so, please match your security certificates! If that's impossible due to a technical issue, then please email me your confirmation so that I can add an exception to Bitdefender.

Question: If it's not coming from Firefox, please email me, letting me know what additional system information you require so that we can get to the bottom of who/what is masquerading as Firefox while attempting to establish an unauthorized Internet connection from my computer.

HP Envy laptop, Windows 10 OS, latest update.

This has been occurring for several months.

Thank you for your time.

So I've got Proton UI forced on me today in 92.0 update and accordingly had to spend my entire evening trying to repair all of the damage. So far I've managed to fix menu spacing and the way tabs look all while not breaking previous walls of text in userChrome.css meant to fix even older UI problems. Still one thing I failed to find any solutions to is the bookmark drop-down menus color issue. Those menus used to be gray, but now they are all bright white, which to me is super annoying. Any tips on how to fully recolor those?
