When I try to download music I have purchased from Bandcamp (www.bandcamp.com) the file that downloads (regardless of if i choose AAC fomat or FLAC) downloads as a TextEdit file which I can usually expand with StuffItExpander. However this no longer works, yet it works fine on Safari.

URL of such a file is download URL of such a purchase

Bandcamp support are unaware of any issues - I updated to Firefox 75.0.1 with no difference in the outcome.

For some time now I have had no audio when playing media on Firefox. I'm on a Dell laptop using WIN 10 and system sounds, iTunes etc all work fine.

I tried the Audio mixer and when it starts there is a speaker with a little x beside it showing even though the number shows 100. Tried with 2 tabs - one plays a video from BBC iPlayer and the other Youtube. Playig with Audio Mixer settings I got the sound to come from BBC video - Youtube nothing. Of course resarting FF set the Audio Mixer back to normal settings again so that isn't a fix at all.

All drivers and Win system updates are in force and my Firefox updates automatically. I use the Sync settings in FF to work between Mac and PC so not being able to use it any more would be a major problem. Any ideas?

With two tabs in use, my fully updated Firefox uses 350 MB of memory or more, about 36% of available memory on this 2013 Windows 10 Pro Dell.

Is this level of memory usage typical, or possibly indicative of a problem?

[Background: My only problem is some web pages taking a long time to load, which could have many possible causes of course. I do employ most of the available security protection in Firefox Options/Privacy and Security, judt use Windows security software for monitoring, show no viruses on Malwarebytes.... I have never before now looked at Task Manager Processes with just a browser running, nothing else. I have checked out the online recommendations.]

Dear Mozilla-Community, I have the following problem:

After deinstalling a Microsoft Visual C++ 2015 redistributable, I got the error message attached below (in German): "VCRUNTIME140_1.dll was not found. Problem could be solved by reinstalling the programme". Firefox could still be opened, and showed my latest bookmarks, but would not connect to any website.

After that I tried the following things (various times) to solve the issue: - Reinstall Microsoft Visual C++ 2015 redistributable (x86 / x64) - Manually install missing .dll-file - Reinstall Firefox - Refresh Firefox - Restart the computer

None of these solutions worked. When reinstalling Firefox, I always get the error-message attached below ("VCRUNTIME140_1.dll was not found.").

I would appreciate any help!

Kind regards, Sören

Hi guys,

I don't know if this is happening to you too, but it's getting me crazy. Since the latest upgrade (firefox 75), I open the program and start working normally. After one hour or so, I can not open any new tab, I have to close everything and reopen firefox again to start opening the same pages I got before to continue working with one more tab. For the first hour, everything is working as normal.

This also happens if I try to open a new window instead of a new tab.

I have tried to reset the profile but this does not do anything. Also, I have tested to start in safe mode without any add-on, but the problem is still there.

Anyone with the same problem?

Thanks!

Since the last update [76.0 (64-bit)], whenever I enter a fullscreen mode in any media player on a website (e.g. Youtube) I can no longer Alt-tab normally, even if I close the fullscreen. Instead it takes 3 times to switch to another window - first press of the Alt-tab combination causes Firefox to lose focus but remain on top, 2nd press returns focus onto Firefox and then the 3rd one actually switches to another window.

This also occurs when simply switching to fullscreen on any other website as well (by pressing F11).

This also causes any newly open windows to be displayed under the Firefox window.

Pressing Ctrl-Alt-Esc minimizes the window normally and the issue does not occur then, however, it occurs again whenever I go fullscreen.

The problem occurs also in the Safe mode. Antivirus did not find any issues, so I don't believe the cause to be external.

OS is Windows 10 Home, 64-bit.

There was an issue yesterday with Firefox going through an update every time I opened the browser. It worked for a short time this morning with the same update issue. Later on, the icon changed from the logo to something else and I can no longer do anything with it.
