Edited since I found the email contact. I've gone back to using an old load tabs progressively extension which seems to partially work but ideally I'd like to use something more up-to-date. I primarily just want to be able to load background tabs one at a time and have it work for all sites, including the new Twitter web experience (based on mobile.twitter.com). Thanks!

Hi, Each time I quit firefox the pausing feature disables and I have to click Pause Loading again. Why does this happen? Could you fix this?
Edit: Hey again! Thank you for your fast response and updating the extension. Yes I am using this extension instead of LoadTabOnSelect. To me it's easier to use and has more options (Now it's perfect and I don't need to have two add-ons installed at the same time). I have another problem. Maybe I don't know how to use the add-on but is there any option to change the state of all active tabs (except the one we are already using) into paused tabs like they have just been opened and then paused by the extension? This way system resources will be freed until we select the tab we want. Thank you again :)

Works great! Now my laptop's fan isn't blasting on full power since numerous tabs are being loaded progressively.

Hello @kgersen,
Can you please add an option to add all failed to load tabs to the line again and start loading them
(if 20 tabs waiting to load in the line and my connection dropped all tabs will fail to load, the option to add them to the line again and start loading them will be very helpful as this situation unfortunately happens to me frequently)
Thanks again for this awesome extension!
Edit:
Thank you very much!
(The "Server not found" is correct but also for the same case I get this title "Problem loading page", you can switch browser to offline mode and try to navigate and you will get it)
I really appreciate your work ♥
Edit2:
I just found the option to change the specific title for the failed to load tabs, maybe it should accept multiple titles
Edit3:
Working great! I'm really very grateful :)

This is just awesome! I missed Load Tabs Progressively very much and this is the perfect replacement. I regularly open more than 20 tabs at ones and without this great add-on some content is not loaded because the loading runs into a timeout. Now I just can limit the number of loading tabs to e.g. 3 and everything will be correctly loaded. It is absolutely beyond my comprehension, why such a functionality is not build into Firefox by default. Thank you sooo much!

nice

A niche extension.., not needed for regular browsing, but very useful for "power" browsing. It's especially useful (a must!) for 'Snap Links Plus' users.
Thank You.

Very interesting, thanks kgersen.

Add on 2018 Feb. 24: Is it possible to change the colour of "L" and the same thing for the "tab count"?

Another nice extension like "load on select" but this one can simulate better the old extension "load tabs progressively" using the hot key "alt+z". Would be great if you could customize the hot key or make like the same extension "load tabs progressively". BTW thank you very much.

The idea is great but from the description it seems that it has a lot of issues that wouldn't make it useful at least to me how it's now. but I'll be looking forward for the fixes.
BTW when you say it's not supposed to work with session restoration or something like that; does that mean that when you restore a session with non loaded tabs from your addon they wont be able to be recovered?

Apparently working great!!!

I used to use Load Tabs Progressively and i missed it a lot!!!

Isn't there a way to avoid users to have to change about:config options manually???

That would be good

(i'm guessing a few will not use the addon just because of that...)
