There are many addons that try to do this but none work (or requires install of separate software).
Therefore, could you please add this feature as a builtin in Firefox?
I'm working in a large++ company where MS Edge is required for a lot of stuff.
But I daily use FF as my main browser.
Therefore, every time I get a corporate email (I read it in OWA), I want to be able to open various links in the email body in Edge.
Currently I have to right click on the link, choose "Copy link", open Edge and paste it into the address field.
This is quite tiresome.
Could you please add a new entry in the right click context menu?
There are several ways to solve this...
a) [Send to >]
When hoovering over, or clicking on this menu entry, you see your own SendTo apps.
(see "C:\Users\<username>\AppData\Roaming\Microsoft\Windows\SendTo" or in short "shell:sendto")
I.e. send the link to whatever app you want, like Edge, Notepad, etc.
b) [Open link in <browser>]
In the FF settings you can set a default alternative "open link in" browser.
In Windows this should default to MS Edge.
c) [Open link in...]
This opens a window where you can pick an application from a list, or browse to a custom path.
I.e. you can open the link in notepad.exe if you want to.
Personally I would prefer option a), since it gives me the most flexibility. I can easily right click and send the link to any app of my choice without a lot of manual steps.
