good

I like the idea, but it breaks the function of links in google sheets. Disabled and they work fine. Happy to try work-arounds or help with troubleshooting if that's helpful.

Works really well, but breaks Google Sheets functionality.

I quite liked this extension, but I don't know why all of a sudden a couple of weeks ago it started interfering with my google sheets (I have tried everything to figure out why it didn't work and it's for sure this extension, when I disable it the doc works perfectly, yet when it's on it will barely load... I have deleted cookies, restarted it, made of copies of the docs... It's, somehow, this extension), it's a shame because I liked it and have been using it for quite a while...

Breaks some Google Sheets functions
(Data validation & named ranges side panel doesn't open.
Doesn't allow you to connect to googledrive on the 1st signup popup on firefox...)

While this looks like a useful extension, it can cause issues with some web applications, e.g. Google Sheets.
This was already reported multiple times (search for "ClearURLs google sheets").

breaks formatting in google sheets

Disappointing; it now disables all popups in Google Sheets: Ctrl+F's find and Ctrl+K's URL-edit boxes, as well as file popups on cell highlight. It was flawless until just a few days ago.

Mozilla Firefox 132.0.2 (x64). The addon breaks search in Google Sheets - the Ctrl+F search command does not launch the search bar. This behavior has only been seen in Google Sheets.

While this is a very good extension, I have found that for some wild reason it disables google sheets from allowing you precisely resize columns and rows

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.
