the problem might be ~/.config/chromium/SingletonLock and SingletonSocketif so add them to your .xfiletool.lst
I accidentally switched off my computer earlier.. Now after rebooting, i tried to launch chromium browser as usual, but it did not open.
I am new to the Slackware and I was trying to install chromium browser. I found out that i can download the slackbuild and source file from the slackbuild.org and can build and install it. So, I did the same.
