Thanks @librewish.
Hello @anon56724355, I do not like Chrome (I like Pale Moon, and minimalist Midori although it has some limitations), but Chrome has wonderful extensions: I dictate my courses assignments, it reads aloud text webpages, I can OCR text on video tutorials, check css, etc. I am testing One Tab extension, memory use decreased, but I do not like to go back and forth to One Tab. With the old distro and same hardware I was able to have open 50 Tabs in Chrome, 70 Tabs in FF, several programs including KeepNote and a Virtual Machine working, and no crash, I always checked with psensor and I still had 3 to 5% free memory of my 16GBs.
Today I installed HPLip minimal a few megabytes and the disk dropped 2GB less free 
and my old good HP scanner is not detected. I do not understand, I had 17GB free, then I installed 5 small programs, but each time it update the system I lost gigabytes, now I only have 5GB free in the SSD I lost 12GB in about 10 days of updates 
, and I cleaned with Stacer.
Now my real critical problem is disk space available in my SSD, because it is consumed fast with the updates, I do not know what to do.
Regards
