Try to clear your browser's cache and remove the cookies.
If you are using a proxy server for your browser, try disabling that.
Disabling plugins could also do the trick. I think edge has a safe-mode launch (launching the browser without plugins), just as Internet Explorer has.
Don't know what a "chan" is. channels?
Cache and cookies aren't browser history.
You can see here how it's cleared in the link below. It's properly not gonna help, but give it a try.

About plugins. Apparently Edge doesn't even support plugins yet.
Maybe it just doesn't work on edge yet. It's a new browser.
Is there any specific reason you want to use Edge over chrome?
Chrome is by far the most popular browser.
I am afraid i can't help you much further in this. Maybe some other members can.
Never heard someone say "depends on the computer what browser is best"
You say you have a computer where Firefox works best. It's not so much about what hardware you are running.
Some browsers do take slightly more RAM to function, but it's still browser. It's not an editing tool or conversion software. It's a browser. You might have some clunky extensions installed on chrome on the computer that runs firefox best.
Chrome is the most popular browser. Mainly because of it's ease of use and features. Also the UI great and minimalistic.
But if you prefer another browser, feel free to use it. It's all opinion.
Well you must have seen this! The solution is only the browser Mozilla Firefox because NPAPI plugins/flags will stop after Chrome version 45. I don't say it doesn't work it does but on some machines Flash player works best on Firefox
