This extension works as stated, with the only caveat being that it disables copying on Google Docs. I recommend it, but only for the moment you need to enable selection; it should be disabled afterwards.

Causes Google Calendar to throw the error, "Calendar could not load the data. Please try reloading later."

god

It works!

Works for me. I needed for a site so that I could select some text for Joplin for a report I was writing.

Full marks. Best extension ever. Simple, does what it says on the tin. Just takes away that annoying little annoyance that some websites feel they need to do.

However, please disable it on Google Sheets (and possibly Docs as well)

It works without a hitch. Recommended +++

Worked fine, thanks!

breaks google docs

it throws error on console:
Uncaught ReferenceError: jQuery is not defined

It breaks some pages, by far I have found the inoreader browsing page. If you click the some menus or buttons which open some popups on the pages, it can't pop back. Additional error message if I enable this addon was below:

Uncaught ReferenceError: jQuery is not defined

Thank you ever so much - very useful!

Does what it says it does, but doesn't feature a whitelist nor blacklist, meaning I have to go into my addon settings to turn it off every time I want to use Google Docs. Annoying, but serviceable. Would be nice if I could also toggle different functions separately, like make it so I can select unselectable text without replacing site-specific right-click menus.

Works as described: It enables text selection and right-click context menu.

However, some websites provide their own context menu and it may be beneficial. It would help to have a toggle/configuration checkbox here to enable/disable context menu override.

It works great on the site, I needed to highlight non-selectable text. But it breaks copying complex objects in editors like miro, canva and figma. And also JQuery is not defined problem appears on every site :)
