When I try to open a hyperlink on a Word doc a new tab opens as e.g. https://twitter.com/trixiemckFirefoxHTML%5CShell%5COpen%5CCommand (this is my own Tw acct)

The hyperlink looks ok but I can't open it by just clicking the left button on the mouse (which I have done for 15 years) and when hovering over it the yellow box appears telling me to use "Ctrl+click to follow hyperlink". And then it takes me nowhere. Twitter opens but with the non-existing address I pasted above. I tried a hyperlink on my invoice template and while the page opens ok, it still looks weird http://www.proz.com/profile/25014FirefoxHTML%5CShell%5COpen%5CCommand. I know I can shift to IE but I did it last week and it took me quite a few hours to go back to Firefox.

That is a problem with backslashes (\) instead of forward slashes (/) in that URL as you can see if you hover this link with the mouse.

Firefox escapes such backslashes as %5C

Edit: This looks that some registry key data gets appended to the link: FirefoxHTML\Shell\Open\Command

And that the link should be this:

The add-on didn't work for me. However I visited the link and on following the instructions found out that when I reached "select extension --> NONE --> File Type URL Hyper Text Transfer Protocol it was to be opened with Internet Explorer (which I haven't used for years). So I fixed that and now can open the hyperlinks. However, I never had to use Ctrl+click to open a hyperlink on a Word doc before and don't know why this has changed overnight.
