Install a "Dev" Browser
I see too many people using a single web browser for everything. this is inefficient. ⌛️ 💸 If you are lucky enough to be on a device that allows you to install multiple web browsers, then having a browser dedicated to running your app is a no brainer because you can switch to that browser really quickly and still have Chrome (or "Regular" Firefox) open with all your other tabs.
I recommend people install Firefox "Developer" Edition: https://www.mozilla.org/en-GB/firefox/developer and run your app in that.
Link to download Chrome: https://www.google.com/chrome
Canary: https://www.google.com/chrome/canary/
I currently have 7 web browsers installed on my Dev machine:

Some are single-function browsers e.g. I use MS Edge just for GitHub. e.g. reading notifications in the web UI. Others are used exclusively to test e.g. Canary for random Chrome plugins. I use Firefox ("normal") as my default "daily driver" and Firefox Developer as my "Dev" browser while building web apps. Then I use Google Chrome as my general purpose "search the web" browser Brave when I want to watch a YouTube video without Ads and Safari for "clean" screenshots because it's the one with the least "cruft".
