Good day, community. I have a problem with Firefox and I have not been able to solve it, I hope someone here can help me.
Since yesterday when I entered Firefox I have run into a red warning that tells me this:
"The bookmark and history system will not work because one of the Firefox files is in use by another application. Security programs can cause this problem. "
I followed the indications of the official doc of Firefox but it did not turn out (of the places.sqlite ), I deleted the cache, cookies and restarted Firefox but still nothing, I even uninstalled it and reinstalled it but it's still the same.
I hope some of you can help me. Thanks and regards.
PS: all this is on Xubuntu 16.04
