I get Video play Error Mozila Firefox version 72.0.2 (64-bit) "Sorry this video is unsupported on this Browser "

weblink https://www.amazon.in/dp/B07X4PXKZQ/ref=psdc_1805560031_t4_B081RTYX3L?th=1

Same video plays smoothly in Chrome Browser.

Firefox 58.0 and 60.0.2 are not allowing their installation in 64 bit windows 10. Nor any earlier version of 72.0 is being allowed. Either of 58 or 60 is necessary because both of them allowed to install add-on like ANT VIDEO DOWNLOADER and IDM 6.32. Anybody please help.

This is actually a rather entertaining issue really. So, what is happening as you can see in the screenshot I shared that Firefox is using a rather flamboyant font I'm not familiar with actually. This seems to happen exclusively within text-boxes on forums where you have control over the font used. This text box, for instance, does not have the effect.

    I have had this happen on a few sites now, and have nailed it down specifically at this point.  It's always a text box, and only those which allow you to change the font characteristics and style.  Without the ability to change font, it uses the fonts from my settings.  Yet, weirdly any time that I get a text box with options?  Same garish font rears its ugly head!  lol.

I am locked in safe mode and even if I changed my microsoft password it doesnt accept it. Right now I am in Linux and my microsoft password is in Firefox password on windows. How can I either import in on Firefox in Linux since there seems to be no option here or find and decrypt the password? Thank you

I have a local file which I can access with the bookmark:

  file:///home/martin/MyFile.html

I want to add it to the new tab page, but I just get the message "Valid URL required"

If I try:

  /home/martin/MyFile.html

it tries to open the page:

  http://www.home.com/martin/MyFile.html

I am notified an update is ready to download and I click. Firefox than goes unstable. Hour glass blinking and jumping around. To stop it I must restart the computer. After restarting, I must go to test compatibility. After running that it will run fine with the new update. This started after 72.0 came out.

I open FF (happens in Safe mode too), and after a couple minutes of running it stops responding to input, but tabs on live websites continue to update content as expected. Then I use the task bar , right click and try to close, the confirmation box pops up but acts like it's stuck in the background, clicking on anything FF does nothing even though it's still running (usually). I've disabled all add-ons, and run in safe mode, same behavior. It acts like it's waiting for input from a process (thread) running in the background and I just can't get to it. Task Manager does not offer the option to bring each thread to the foreground to inspect. Patched to the latest version.

Any Ideas?

Version 72.0.2 - Having a problem for the last couple of weeks with several websites where when a website wants to open a new tab, simply opens a blank page. Other browsers work fine. Any known fixes for this? Any way of completely uninstalling the app so I can reinstall it?

I use a password manager to store log in data and though this data populates, the log in does not move me forward. Rather, I'm given an error message that I have to log in in order to perform transactions, which of course I've just done. It's a circular effect that doesn't resolve. Using FF 72.0.2. When I use Chrome, I can log on easily. What has Firefox done to confound my log in; I think this began to happen following the last FF update.

I noticed an error by off-chance while using Facebook. I clicked a link which lead to a site I've visited before... but. The moment I clicked it went to the Tab screen. Brought my other tab to the home screen. When I tried to go forward, back or type in new address it would not let me do anything. I shut down PC through power button. Turned back on and let me browse as normal. Did a scan, have found no virus or malware.

Sadly, i don't have an error report to give and I couldn't inspect the elements to see if something was messing with it. As it would just continuously reset my page screen. This is the first time this has happened.

Firefox is listed twice in my start up files area. It is only once in the uninstall area. It is installed in my program files and the maintenance files in my Program Files (x86). When I click on them they pull up different programs but when I look at the version they are both the same version. How do I get rid of that 2nd Firefox in my startup. It is driving me crazy with the duplication.

I have send some tabs "for further reading" to device I believe has some name like "Firefox on office computer" and received none of them, but none of them was received. So I checked settings and actual name is "Firefox on localhost", that occured I think after upgrade. Both devices are displayed as possible targets, and account page says that "Firefox on office computer" seen last time long time ago. How can I get list of tabs waiting to be opened on this dead instance?
