Browser integrations cannot be installed along with Rons WebLynx because the browser vendors, like Mozilla and Google, do not allow extensions to be installed into their browsers by third parties.
Whilst a little inconvenient this is the responsible thing to do. Their software connects your computer to the Internet and it is impossible for them to check all possible combinations of software.
To be able to add links to WebLynx from your browser, a browser extension needs to be installed from the browser vendors website. Depending on your browser, please click on one of the following links and follow the on-screen instructions.
