it depends on the game[s] you like. Some of them works on linux, but others work only on windows.

Try deleting the hidden mozilla folder or even just rename it like .mozilla.old .
Make sure firefox is closed 1st. Before doing the above

After finishing with the mozilla folder mod. Restart Firefox. It should make a new folder and act like a new install.
You will lose all settings and addons .
Like starting over on a install.

Edit: Advice pertains to deepin firefox. Not Windows Firefox.

slow with deepin you are saying - I would recommend installing something like LXLE or bodhi linux. They both use apt as well and run quite well on old hardware.

I wouldn't use deepin anyway, there's a chance it could be spyware

What games do you like to play? Look them up on protondb for steam games or winedb for others

Where Linux really falls to its knees, however is video editing. Kdenlive is quite nice for some light editing, but Windows really has the better video editors (you could look those up on winedb too, maybe linux can run the certain editor you like!)

follow the directions for addressing the FireFox issues as that is a good starting point.

Download a few LiveUSB, try Ubuntu, Fedora, OpenSuSe, and maybe a few others to see if you have any better performance before making the leap.

As for gaming, check out Steam for Linux. It has better support than what I have seen over Wine for gaming. As stated many games do not run properly or run as well as they do under the native OS, ie MS Windows or Apple OSx.

For editing you did not mention what type of editing you are talking about. Companies like Pixar use Blender https://www.blender.org/features/video-editing/ for making their movies. There are also some very good audio editing tools out there as well.

The newer vs of MS Office requires win10 (Office 2019), I have not been successful at getting Wine to properly emulate win10 64bit environment to install Office 2019, but LibreOffice and OpenOffice run well as long as you do not have a lot of vba scripts running with your Excel spreadsheets.

Many systems can be restored to the original as sold state. May be worth a try.
