Glad you like it :)

Sorry, how long the notifications stay on screen isn't for my addon to decide. The issue with other downloads is an old one that should be fixed since long ago. Are you sure your firefox and addon are up to date? Please use my listed email address to reply.

Glad you like it. Sorry it doesn't work well on twitter, but that's part to blame on twitter with their weird :orig URLs. If they just followed normal conventions, everything would work fine. That goes for all addons like this that need to analyze webpage content: the more the website deviates from standards and "does their own weird little thing", the more they'll break integration.

The wrong popups were a bug I fixed long ago. "Not working at all" is not normal, sounds like there's a personal issue with your browser. I'm very much alive and keeping my addons working.

If you post in the correct place (a gitlab issue aka the "support site" on the main page here, or an email to me) instead of misusing the review feature (I swear, it's like a trend nowadays) I'll gladly try to find out the problem and fix it for you.

Add another hover button? You mean a different look for it? Post an issue on gitlab or email me for further discussion please.

Downloading to a folder outside the browser's default download dir is not possible (even if I wanted to, it cannot be done) and an anti-feature anyway for technical reasons (hence why they made it impossible).

Sorry about the subfolder and rename feature being broken at the moment, but that's due to firefox's incomplete API. It works in chrome.

If I remember correctly, nstagram is one of a few hosts that have a very strange internal layout on their webpages that makes it impossible or very difficult for an addon to download their images. Twitter and a few others are also guilty of it. I can give them another close look to see if I can fix it but there are no promises.

Isn't the "Save image as..." menu command in your browser good enough? My addons are not meant to include everything and the kitchen sink, only to fill gaps in what browsers offer.

Thanks for the rating, glad you like it.

Your feature requests are kinda asking for a lot though. Detecting duplicates is way out of scope for a simple addon, trying to find linked bigger versions of an image is a logistical nightmare while a user can do it himself easily, and downloading all in an area is a very tricky thing to do. Determining the "pattern" will often not have the result users want either and will be heavily affected by every individual website's structure.

I get the feeling one of your underlying problems can be solved another way: I use my other addon Copy Selected Links to get the full-res links of images in a thumbnail gallery, and throw them into jdownloader or similar programs to get all the full-size pics. Maybe that solves one of your problems?
