DOES NOT WORK.

Simply doesn't work. Might have worked before I tried this extension. So, don't waste your time adding this extension to firefox. You'll just end up removing it like I did.

Doesn't work.

Does not work on Facebook. Facebook is still refresh your feed after you read an article in another browser tab. Yes, I added the Facebook https link, restarted Firefox and I got the S symbol at the extension symbol while surfing on Facebook. Facebook still refreshes the feed! Since stopping Facebook from doing this was the only reason to install this extension, I removed this extension again.

it doesn't work at all

It works very well, but not automatically !
It's necessary to do what the author explains in the presentation :
"URLs can be blacklisted through a tab's menu, right clicking the toolbar icon, or by selecting 'Options' for this extension.
A button badge with the letter 'S' will appear over the toolbar icon if the active tab is being stopped from auto reloading.
Left clicking the toolbar icon with a button badge will reload the current page."

Does not work with Facebook.

Sorry, the only feature I need is: Stop Facebook from reloading!
That's exactly what doesn't work!
Crap!

Tried this app on Facebook based on a few Google searches, guess what, did not work.

does not work with Facebook and it seems that the Dev does not attend to these reviews

Works as desired. Press the right mouse button on the website and add the hostname to blacklist, then reload and you should see a red "S" symbol.

Exactly what I needed. When I was moving multiple internet market tabs they're all started to reload and that slowed browser. This extension stopped it.

I downloaded and installed to stop twitter from reloading. now none of my videos on twitter will play and the page continues to reload.

Does not stop the meta tag http-equiv="refresh".

Ever have a tab on Twitter/X pinned and come back to it later, only to have the whole page hard-refresh before you can read it again? This fixes that annoyance no problem. BTW I logged into my Firefox account for the first time in 5 years to leave this review, that is how happy I was that this annoyance was solved. THANK YOU for this plugin! 💯
