I am frustrated by not being able to get these two extensions to work: ClearURLs Copy-n-Paste: Clipboard Upload Simplified ClearURLs doesn't seem to do anything. URLs do not get cleaned as expected. Copy-n-Paste: Clipboard Upload Simplified just doesn't work. It gets invoked as expected but does not recognize clipboard content nor let me browse for a file. Could there be anything within my Firefox that is causing the problem? Can live without ClearURLs. I was excited to find it but have been cleaning URLs manually for a long time so all I hoped it would do is save me some effort. OTOH, the Copy-n-Paste extension would allow me to make Firefox my default browser. I am very active in a number of support forums and often post screenshots. The inability to upload clipboard content when using FF makes it too inconvenient to use for these forum sites. Vivaldi and Startpage have this functionality built-in so one of them gets used. I prefer FF as a browser though so I wish I could get Copy-n-Paste to work. Thoughts on how to do that would be appreciated. Other installed extensions are uBlock Origin and Privacy Badger. They both seem to work fine.
