A whitelist would be nice. It may exist, but the FAQ on the homepage is 404. This breaks Google Sheets and leads to funkiness on some other platforms.

Does exactly what it advertises.
Perfection. Goes well with other addons.

Breaks Google Sheets pop-ups and probably some other (Google) pages too, see: reddit.com/r/firefox/comments/1gggcsb/google_sheets/. Other than that it hasn't impeded my browsing, so it does seem to work.

Seems to break certain sites (mostly financial sites) that use internal redirects once you're logged in, causing the redirected pages to hang. Doesn't have an easy way to except certain sites that I've found.

Worked quite good until recently when some side menus in Google Docs stoped working entirely. The issue disappered as soon as I turned off this add-on when I was checking them one-by-one...

Works good for most site, but it would be nice if it also stripped tracking URL from AliExpress. Opera browser, can do this out of the box no addons. So it should be possible with an update to the plugin.

К сожалению, работает через раз. Разработчику этого дополнения нужно исправить все баги. Жаль, что других дополнений по типу этого нет в магазине из тех, что отслеживаются Мозиллой.

I like it, sadly I noticed its breaking Google sheets. Can't use Ctrl+F with this enabled. :/

Cannot upload to iCloud while CleanURLs is enabled. Issue reported 3 years ago here gitlab.com ClearURLs/ClearUrls/-/issues/827

Good extension, however it currently breaks google sheets (and probably other stuff) so I can't recommend it in the current state.

it's been pretty good so far, but prevents a couple of websites from working, and there's no way to whitelist sites, as far as i can find

Works Great, I especially like the options in the context menu (right click)
