When I connect to my home router via HTTPS I get a popup with the message “Invalid Encryption Key”. I tried using other installations of Firefox and I don't get this pop up. I then made a new Firefox profile on the same computer and did not get the popup. So it seemed like a Firefox "refresh" would be in order. But after the refresh the problem persists.

So how do I resolve this issue?

Firefox is the latest version running on a Mac.

Hello, Why does Firefox convert my mp4 files to 3gpp files when I download them from my personal Flickr account?? Chrome does not - they download perfectly when I download videos from my Flickr account using Chrome - so why can't I download them as mp4 files in Firefox???

Thank you for your assistance in solving this issue

Operating System Ubuntu 20.04.4LTS on AMD® Ryzen 3 pro 3200g 64bit processor. Firefox Web Browser version 100.0.2 (64-bit)

The method I can reproduce sound distortion:

I have clear sound playback through both system HDMI speakers or if earphones are plugged in, verified using the Ubuntu Sound Output test left/right (without distortion)

Then if I open a normal Firefox window and listen to YouTube video for example I have no distortion, if I however open I private window, say to access training material on Microchip University site I suddenly have distorted playback.

Please advise why private window opened suddenly distorts my output sound. Sound suspicious.

Hello! I hope this is the right place to ask.

So i used glassmorphism on a simple webapp (backdrop-filter). Wrote a Fallback for firefox with the help of ::before and filter:blur() as backdrop-fillter's are sadly still not supported, eventhough they look really really nice.

How ever the fallback works on macOS as expected but on Windows Firefox behaves very very wierd. First of all the blured effect is behind everything else and you have to change the z-index to actually see it and if you do it is actually much larger than it should be. If you play around with the z-indexes you actually get the blur at the right position but the area is still much larger than on mac and not fitting the border at all and after a few hours of trying, I'm not sure if this is a bad by me or not. Kinda feels like it shouldnt behave like that.

About a week ago, Firefox stopped updating the fonts on Canva art boards. I have attached a screen shot to show that the font name is correct (shown in the menu bar), but it is not reflected on the art board. The screenshot also has a popup of the image downloaded which shows the same font as in the menu bar.

I have used Canva in Firefox of years! I am now having to use Chrome and Edge. I would prefer Firefox. Please fix the problem.

When opening History the column headers are there but no dates are shown in the Added and Last Modified columns. These columns are selected in Views and the listed web pages appear to be correctly sorted into Added date order. My browser is up to date an is 100.0.2 64 bit. Thanks

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

upon enabling "do not connect to http" very, very, very often i got the attached error message when the site said it was https and it was very often reliable places like my bank and TaxAct. It seemed like such a good idea but i quit out of frustration.

In my Firefox setting, I have set it so that whenever I try to download a PDF it asks me how I want to open it. This did not always happen but whenever I ask the file to open with Firefox, the file opens in a separate tab but now it still downloads the file to my computer.

Ok, there might exist a solution to this, but I am not able to find it or even a better way to explain it.

So, the main issue is, I have a lots of tabs open on my Firefox (Linux) and after some minutes of inactivity, Firefox automatically deletes all the data associated with that site.

So, when I switch back to that site, it reloads.

The main issue is with Whatsapp Web, as I don't get notification if I don't switch to the tab every now and then.

There might be a option for this behavior in the settings but I can't seem to find it.

Please help me find a solution.

Thanks

Dear Mozilla Community members,

For a while now I get sort of an error message some time after Windows start (every time): "XULRunner Could not determine any profile running in backgroundtask mode!"

I managed to find out that XULRunner is connected to Mozilla but I haven't found any info about this particular message so far, therefore, I would appreciate your help solving this issue.

Thank you in advance.

Kind regards, Ewelina

I'm trying to print this article( https://www.nytimes.com/2022/05/25/books/review-lynching-port-jervis-philip-dray.html?searchResultPosition=4 ) in Simplified Format but its duplicating the images. I tried a different article and it did the same

I asked this question some time back here: https://support.mozilla.org/en-US/questions/1362859 I'm asking again to reframe the question. The problem is - if my experience is a guide to the rest of the world - VTT files (which are used to caption HTML video) are no longer read/loaded by Firefox when it is viewing the HTML file locally (i.e. file://). On the web they are loaded as expected. Presumably there's a security setting somewhere in Firefox that now refuses to load the VTTs locally. Maybe under Help > More troubleshooting information there is a setting to change to fix that?

So I wanted to join Rally, but I am concerned about granting access to my passwords and logins to the Rally clients. If I create a new profile and sign in with my only Firefox account will Rally clients have access to my passwords and logins from other profiles?

Thx.

Using Windows 11 and want to set Gmail as my mailto option when clicking on email links on websites. Under Firefox/Settings/Mailto I no longer see the option for Gmail, not an expert on technical matters so I have googled the problem but still can't find a solution. Do I need to find an App on Windows or perhaps an Extension within Firefox, feeling completely lost at the moment.

I'm using a desktop with Win 10, i7, 16GB mem, 1TB hdd, hardwired internet @ 200mbps. For the past 2-3 days, when I click on the Firefox icon nothing opens for as much as 2 mins. All I get is the link in the top bar. It also happens when I try to change accounts, both using Firefox. I have absolutely no problem using Chrome to access my two accounts. If I close Firefox using the small X on the top line, next time I click on the icon what comes up is a blank page with previous sites used. When I click on one, same thing - takes forever to load/open. I uninstalled/reinstalled yesterday, no help. What do I need to do to fix it short of permanently eliminating Firefox?

Dear Firefoxers,

Over the last year or so, I've had to switch to Chrome to load some pages properly. reCAPTCHA is proving to be a particular problem - which I'm told is powered by Google? I could be blocking Google content too much within my Firefox browser?

My wife is a long-term Chrome fan and says, "I don't know why you bother with Firefox, Chrome is much better", but I rebuke and say, "No! It's been great over the years, I've been using it since 2003".

Do I need to change my settings somewhere? At times certain pages don't load - it'll say 'Click Verify; or something similar and the 'Verify' button doesn't appear - I load the same page in Chrome, and boom, it's all there.

Am I doing something wrong with Firefox? I have version 100.0.2 (64-bit). Or is it time to give in to the mighty Google and go to Chrome after loyally using Firefox/Mozilla since 2003? (A daft thing to ask on a Firefox forum, I know!).

Many thanks if you can help or advise.

I refreshed Firefox and all my passwords disapeared even though it stated they would be saved. I followed online instructions and copied and pasted the old data into the new profile. Although I can see the old login data is there nothing shows up in the saved passwords section in settings. HELP! all my passwords are badly required as I have no other record.
