firefox and website administration

[optophon]

when editing web pages in the browser, firefox or the extension writes rubbish into the html code without being asked. that's not good. it's **bleep**ty!

To determine which extension inserted the background image, you can look up part of that url() on the about:debugging page. Here's how:

• Type or paste about:debugging in the address bar and press Enter/Return to load it
• In the left column, click This Firefox
• Call up Find in page (Ctrl+F, or on Mac, Command+F) and look for db7276

Firefox should show a match in an Internal UUID for the add-on which inserted the background image.

danke für ihre antowrt. welches add-on meine html-codes manipuliert weiß ich, steht in dem beigefügten screenshot. solche manipulativen add-on's haben auf der plattform mozilla nichts verloren. ich mußte bei rund 100 artikeln den code-müll per hand entfernen.

You should tell the add-on author about the problem.

(I had this problem with a user script I posted years ago that adds a dialog into Google search pages. I didn't realize it also embedded the code into documents or blog posts people were creating on Google platforms. After being alerted to the problem, I was able to fix it.)
