The problem with downloading movies is twofold:
1. It fills up your hard disc, so you then eventually have to jettison movies to make room for new ones.
2. When you delete movie 'A' to make room for movie 'B', then go back to that site to download movie 'A' to watch it again in a year or two, you may find its no longer there, or the site maybe kaput, and you will have to go looking for that movie again.
The solution is to burn it to DVD or transfer it to an external HDD. Burning to DVD is cheaper. The problem older actors all have is that good parts dry up, and Hollyweird only sends crappy jobs their way...at least Liam Neeson has resisted doing a remake of 'Plan 9 From Outer Space'!
My archiving media over the years:
Floppy->CDR->DVD-RAM->DVD-R->BD-R->currently two different brand internal 3.5" 2TB harddisks on USB adapters (on XP).
All the 2.5" harddisks I tried have too high a data density for reliable longterm storage, so I use 3.5" for archive drives (most of my always on RAID1 drives are now 2.5" for physical space and power consumption reasons).
I mainly switched to harddisks because it wasn't practical to automate the process to BD-R (not to mention I had some recordings longer than a BD-R can hold). It's probably now cheaper too. As I have ~200-400GB new data per day during the recording season (14 HDTV tuners on two XP boxes), automation I created was the solution. With it, the amount is whittled down to about 50GB per day on average, which is practical to store 3 copies of (via automation)- two to the 2TB drives, the 3rd copy to my HTPC file server (96TB, soon ~288TB).
I don't download anything that I can buy on Bluray or DVD. I have an XP VM set up just for ripping these. The process used to be brutal and fragile. Newer tools have gotten better but some have date usage restrictions (not a problem with VMWare Player's total control over the VM's clock).
My favorite video player is MPC-HC. It's ok by itself, but it's awesome when combined with FFDShow and my app that stores all the video's important MPC-HC and FFDShow settings into a database for later recall (no the app is not done and it only works on XP).
Umm... wasn't this thread about web browsers?
I seem to be in the minority running (on XP32) a Linux Mint virtual machine with Firefox- currently v53 so all the legacy plugins I rely on work. I disabled updates on all the plugins as some updates will kill the plugin. I cannot function without Classic Theme Restorer and Mozilla Archive format. Sometime in September 2018, Mozilla said MAFF won't work. We'll see about that.... if need be, I'll write an app to fix the issue.
Note for your VM to be reasonably fast, the VM needs to be on a SSD. You also need a FAST XP pagefile.sys or you'll be in page fault hell. Either use a dedicated SSD or for best performance- a RAMDisk using unmanaged RAM. I use Superspeed RAMDisk with 8GB system RAM to give a 5GB ramdisk with a 5GB pagefile.
The downside to running FF on a Linux VM on an XP32 box is there is a limited amount of RAM you can allocate for the VM (and lock in RAM). I've found 1.3GB is the best compromise. This limits the number of web pages you can have open at any given time before Linux goes into pagefault hell.
The other main issue is lack of Abobe Flash support in Linux.... Youtube works via HTML5, but if I didn't have a Windows 7 box with up-to-date antivirus available via VNC, running Firefox, Chrome, and Flash, I'd not be happy- no Spotify on XP or Linux. I have Windows 7 streaming audio to Winamp on my Win2000 jukebox (via Edcast and Icecast). This gives the Spotify audio the same iZotope Ozone DSP effects I use with all my saved music.
There are still many sites that are safe and work on XP with Firefox 52. Wikipedia, Youtube, Bandcamp (Flash) work fine. All the institutional sites I use (banks, etc.) work fine. For today anyway.
For message forums and online stores (Amazon, Staples, etc.) XP is NOT safe. Win7, 8, 10 is NOT safe. Due to third party ads being hosted, you can wipe out all your PCs and data with a SMB virus ransomware attack. Thus I use my Linux VM + FF for any shopping or any unvetted site.
So long term, it'll be a combination of web browsing on XP + FF v52, Linux with FF and/or Chrome, and Windows 7 with FF and/or Chrome depending on the web site. I have like 40 FF profiles on the various PCs. As I share bookmarks via Firefox's cloud share, where to safely open a site is all in my head... I need to figure out a safer solution.
