@arubislander I uninstalled Webber some time ago and started to use simple browser bookmarks.
The reason is, that you have to add every URL ((sub-)domain) a website might use. Otherwise there's a fallback to the browser which has no passwords (cookies) stored, keeps opening new tabs etc. which is an annoying behaviour.
E.g. for eBay I had more than 20 URLs. And always another one came up (hard to catch due to forwarding) and I had a fallback to Morph again. To add a new URL I had to create the Webber-Shortcut again and add every single URL...
If Webber was able to reopen a shortcut with all settings made, that would be a game changer (or didn't I just see that option?).
I could revive this if your suggestion works, but I'm afraid you have to tell me how to add the user agent header and which one (maybe there are options in Webber. I have to install and check first)...
