I am trying to make Firefox start streaming every time I click on a magnetic link. I followed the instructions at https://support.mozilla.org/en-US/questions/1012864 and managed to successfully obtain the window & # 39; Start application & # 39; when I click on a magnetic link. However, when I try to navigate to the Transmission directory to select it (which in my case is in
/usr/bin/transmission-gtk), Firefox throws an error right after trying to access
/usr. The error says "
Could not read the contents of usr. Error opening directory /usr: permission denied"Here is a screenshot that shows the error:
I'm not a permit expert, but apparently
/usr/ It is owned by root and everyone else has read permissions; this is what
ls -l / Returns:
drwxr-xr-x 12 root root 4096 ago 15 23:23 usr
Firefox processes are also my property (hulahop is my username), according to
hulahop 23113 8.1 4.1 3456980 684420 tty2 Sl+ ago15 2:18 /snap/firefox/243/firefox
There are other secondary processes but its owner is the same user. How could I have Firefox forward magnetic links to Transmission? I am running Firefox 68.0.1 (64 bits) on Ubuntu 18.04 LTS. Firefox was installed directly from the Software Center and its permissions are configured as follows
Firefox Software Center permissions
Another problem I have with Firefox, which I suspect could be related to the previous one, is that Webgl pages no longer work. I have webgl enabled by force within the
about:config page (as indicated at https://www.sitepoint.com/firefox-enable-webgl-blacklisted-graphics-card/), but still nothing. I am sure that it is not a problem related to my graphics card or its drivers, since the pages with webgl technology work perfectly in Chromium, which is also installed on this computer.
The funny thing is that Firefox used to work fine until (I think) the certificate expiration scams that killed all the add-ons a few months ago. Prior to this, you could use the 3D satellite view of Google Maps without problems (which requires webgl) and handle magnets correctly with Transmission. But when that certificate expired, I had to replace Firefox with the Nightly version for a few days, then return to the stable version, and a few weeks later I began to notice all these problems …
Does anyone have any ideas? Any help will be greatly appreciated.
Thanks and best regards,
PS: Another fun thing: I just discovered that I really can't change the permissions defined for Firefox in the Software Center. Every time I press any of the switches, I am asked for the root password, and then I can change all the options I want. But when I close the window and open it again, I don't see any of the changes I made … My Ubuntu is terribly broken, isn't it?
