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.

Hello,

Since the new update(s) I'm having major issues with the settings of my Wordpress website. It seems I'm not the only one having problems adding a user in Wordpress - which is impossible in FF, it only works in Chrome. https://wordpress.org/support/topic/cant-set-password-for-new-users/

But now my major problem is that the changes I make (see screenshot) are not saved in FF. So when I log out of WP and FF, then start again and login to FF and WP, the changes I've made are not shown, in other words, the old situation is back.

I disabled ALL of my add-ons, that seemed to work for a short time, but as soon as I was testing the add-ons, to find out which add-on was corrupted, I now have the same problem again, and all the add-ons are OFF.

So I'm stuck here, and find the errors I see in Wordpress bizar it can be caused by FF.

I'm using the latest version of FF, which is a beta which I don't like, but as soon as I try to downgrade, I am getting page crashes all the time.

Am I the only one having this issue?

I need some help please!

Site design switch to dark mode is broken for me in Firefox Developer Ed. 92.0b3 (aarch64 on M1 machine) at multiple places like manning.com and their Live books or at spring.io. This not so on my intel Mac where this works fine.

I switch to the site's own dark mode. Unlike in my other browsers, the site theme doesn't change. This means Firefox Developer 92.0b3 cannot render one of the designs of the site. I've also tried with all extensions off and this doesn't change anything.

I think this worked when the install was fresh, but clearly something broke. It could be an aarch64 bug, but unsure at the moment.

I'll try with another profile, but it would be nice to find the actual cause too.

Any ideas?

after the last several updates, images on https://www.dailymail.co.uk/ushome/index.html are not being displayed. the show in chrome, ie, and edge. I've "refreshed" firefox and cleared data/cookies/etc to no avail. ver = 92.0b4 (64-bit) any ideas?

HTML5, YouTube, and Netflix video playback does nothing

Playing HTML5, Youtube, or Netflix video does not work at all for me - Netflix throws an error code, while Youtube and HTML5 simply never stop loading.

I've tried

• Starting Firefox in Troubleshoot Mode
• Clearing the cache and cookies for the given website
• Refreshing Firefox

On the chromium-based edge browser, video playback works normally.

DRM-controlled content playback is enabled, hardware acceleration is disabled, allowing auto-play doesn't help, and neither does disabling Tracking Protection.

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 have like 100 Firefox profiles that i use for different topics and would love to sync them all at once, i was looking for a file that stored the login approved for my Firefox account info to just copy paste that one file in all of my Firefox profiles, but can't really find it.

This is a problem because every single time i have to introduce my email and my password and sometimes it also asks for an email verification code :( .

Hello,

I love the tagging bookmarks feature in Firefox. But unfortunately it does not work properly like explained in the help docs.

I search for tags by typing '[+] + [Tag]'. This works for me but I only can search for 10 entries maximum.

Why there is this limitation to bookmark entries in my search bar? And how can I see all my tagged entries even when there are more than 10?

Kind regards Benni

After my antivirus deleted a malware I get an error message at boot " unable to access jarfile". Since then FF doesn't convert html to pdf and external programs don't start for unable to access virtual machine. The jarfile is binary.SE and the Pass is correct. I have no old java version and I reinstalled the last java version. I understand that binary.SE is no longer supported. The list of extensions also include .jar so I unfortinately don't know what els to check but I do need the FF html converter back. Thank you so much for trying to help. My OS is Windows 7 Pro FF is Developer edition with auto update. Alf

Hello,

I'm using firefox-dev under linux debian buster and would like to keep it as my default browser and even more after all those recent articles in media where they say firefox is loosing its users.

I received the newletter from netflix and I tried to watch a trailer (https://www.netflix.com/watch/81387952?trkid=13710079&MSG_TITLE=81387952&lnktrk=EMP&g=79ECBFC7B02B1269F43D15B11C9BA9F56455502C&lkid=TRAILER_CTA) but even after i clicked on accept drm, the video was stuck nothing happened I just saw one single fixed picture of the movie.

Later, I was on facebook, trying to watch a video (https://www.facebook.com/demotivateur/videos/5009752875718446) and the same here without any DRM...

For both of the cases I opened chrome pasted the url and video played very well.

Is there something to tweak to make it work ? Is it because I'm under debian ?

I don't want friends to switch to chrome but I understand them sometimes.

Kr,

Eric

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.

For the first time in over a DECADE I went to Log Onto Tracfone.com to check on the cost of buying a One Year Service Card, which is what I have done at this time of the year for OVER A DECADE!

The following Tracfone Problems are occurring on Firefox BUT Working Just Fine on EDGE (1) My attempt to Log On with what I KNOW is the Correct User ID and Password keeps reporting "Invalid User ID or Password" (2) Attempting to tell Tracfone to send a Password Reset Link FAILS. NOTHING Happened, just a short flash where it is trying to process the request. (3) Attempting to have Tracfone Verify what my Username is FAILS. Again, NOTHING Happened, just a short flash where it is trying to process the request.

As I have stated, I had NO PROBLEM Logging On using EDGE! And had No Problem on EDGE requesting Tracfone to Change my Password and it is this Password Firefox keeps screwing up on the Tracfone Logon Screen because it keeps reporting "Invalid User ID or Password")

PS-This type or problem is ONLY HAPPENING WITH THE TRACFONE WEBSITE!

Hi! I'm going nuts. I have Firefox set to NOT remember sessions when I close and re-open. But every time I re-open the (latest) Firefox on my (up to date) Mac, 3 tabs reappear. It doesn't matter how often I delete history or cookies or empty caches. They are not even 3 tabs from the most recent session! They are from a week ago. And no, they are not pinned tabs!

And yes, I have reinstalled Firefox.

Any idea what I should do?

Many thanks!

David

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.

I'm running Firefox DE on a M1 Mac, and I have the 64-bit edition. However, I'm unsure of whether or not this version of Firefox is fit to run on this architecture or not. Anyone know a way around this to get the most recent M1 application but the Developer Edition?

Hi, Since the last update, when I click on a link, the new tab can't be launched. It opens and closed immediatly. I have to click a second time to open it. It is the same problem when I open a new tab manually, I type web address, and when I click on "Enter", the tab closes... I have to do it again and it works. It is not the first time. Next year, after an update, I had the same problem. No change on my systems (Windows 10) and on my MacBook too... Is there anyone who have the same problem ? How to resolve it ? Thank you

Hello at all guys. In the moment I'm currently writing this post I'm using FF developer edition as my main browser. The problem is with the True Key extension: When I try to use it in private windows, it doesn't work. I can't interact with it. If I try to open the extension, just as if I'm on a different browser like Brave or Chrome, it's doesn't open up the home page of the extension. But, if I try to open it on a normal window, it works perfectly and I don't why. I also want to say you guys that in my FF settings, in "Privacy and Security" at the "History" section I've enabled Firefox Developer Edition will never remember history..
