V58 is two steps back
Upgraded from V56. V58 has lower quality look (theme) with black & white bookmark toolbar folders. Couldn't find add on theme similar to V56. Can't see "+" to open new tab. It's there, but default theme doesn't show it. Horrible step back. Performance is MUCH slower (W7 64-bit SP1). As an example, Options Tab, mouse scroll to page down doesn't initially work. Nothing happens. Wait, then scroll works. Same delayed/no scrolling response on other website pages. Reverted back to V56 to test. Options Tab scrolls immediately. V56 is much faster. V58 is prematurely released. I do not want to spend time finding more problems with V58 and troubleshooting them because of the poor pre-release testing. I will look for future bug fixes and reviews before upgrading.

There were some whom created css to make it look better from the standard factory looks. Did you try looking for such options? And performance of FF58 isn't slower as you would like to think. There is no problem with FF58 unless you can provide technically logs showing otherwise. There been plenty of steps others have been giving from removing all FF old and new and reinstall the FF57/FF58 from clean install. But if your not going to at least read those helps then only the reader is at fault here.
