Although I do like this add-on, unfortunately it 'has' started to interfere with Wordpress admin.
I explain.
When you are editing a page and chose Text (i.e. source side) it locks it and I cannot do anything, as if there was a layer protecting it from editing!
I now am forced to switch it off and if I forget - i.e. edit a page after a few weeks, I tend to go stupid for the next 30 minutes until I remember it is your add-on. Please fix it as I like it! Hence 4 starrs or would be 1 star.

Mostly functions as described. On install, disabled in Private window doesn't work as stated.

As far as I can tell, this plugin works most of the time. (Because it just restores default functionality, it's invisible when it's working properly, which makes it harder to gauge.)

I came here because I ran into a website that mangles copy and paste (Bloomberg Quint), and I wanted to notify the developer about it. Unfortunately, there doesn't seem to be an issue tracker for this, or even any sort of contact information; doing a web search or scrutinizing the underlying doesn't reveal anything, either.

So I guess I'm deducting a star because even though this plugin seems to do what it's supposed to do most of the time, there's no obvious way of reporting bugs or instances of websites not working correctly.

tl;dr Please add a link to a proper issue tracker or at least some sort of contact information for reporting bugs. Thanks!

Parfaite extension quand on en a besoin, mais les dernières versions doivent être désactivées la plupart du temps, parce qu'elle empêche le copier-coller dans la recherche, ainsi que d'autres soucis ; apparemment la version 1.1.6 encore disponible, n'a pas ces soucis, (sous Linux) je viens de l'installer et empêcher sa mise à jour, et je peux copier-coller dans les barres de recherche des différents moteurs. En espérant que Firefox ne la déclare pas trop vite comme obsolète.

Nice addon I liked using several years.
I left one star out actually just to point out a bug I stumbled upon this week : Facebook writing/commenting/posting has become really messed up and I realized disabling the addon solved it. Hope the signaling may help for the future
Cheers,

This just stopped working (May 15 2021) for www.uol.com.br

Could you release a new version which enables it on local files? Not only on http(s)://

It always work but it you still have to manually click it

I give it 4 stars because I found out that this add-on interferes with Facebook. It won't let me post, comment or respond to messages. What I did: I restarted Firefox with all add-ons disabled and I was able to post, comment etc. until I reenabled this extension. So, yes it's working but I have to disable it when I'm on Facebook.

I love this add-on EXCEPT that in Firefox 84.0.2 (64-bit) it's showing as a whitespace on my toolbar. To use it, I have to go to the add-ons menu, click the 'Enable' button off and then on again, and then it shows in the toolbar. Then I still have to enable copy and absolute mode. That's why it only gets 4 instead of 5 stars.

It's been very useful but if you use it on Facebook it breaks all text fields.

To "@Firefox user 12246247", on some sites you can't even select text so that will not help you if you press shift+right click. This add-on will make that possible too. It is also nice that it remember the sites it need to be enabled on ...

Not working at
https://letters.gov.spb.ru/reception/form/
("Содержание обращения" field)

Maybe some kind of key press emulation is needed in such cases?

It works great but I had to disable it because it breaks Facebook. I hope you can fix it.

Great little add-on. 4 stars because once active you have problems with Facebook.
