Chromium (which IS open source) apparently has build issues and isn't even in the normal Fedora repos.
Fedora's fault. In Xubuntu, a Debian derivative, all I have to do is sudo apt-get install chromium-browser.
And the memory footprint of all browsers is crazy now.
Is this the fault of the browser or of the sites you visit? Back when sites weren't as image- and script-heavy, like Better MF Website, a graphical browser could actually fit on a 16 MB machine. Nowadays sites are covered with carousels full of high-DPI photos, plus developers think they still need jQuery and all its bloat just to get the site out the door faster.
I also don't appreciate them throwing unnecessary crap into the browser like the web developer stuff
Browser developers distribute the debugger with all copies of the browser to keep sites from intentionally detecting a debugger's presence and stopping working if one is found. If everyone has a debugger, the site operator can't block people who want to tinker, learn, and make a site more usable without blocking everyone.
