On Firefox 146.0.1 for Ubuntu number of all and unread articles are not updated when new articles are fetched. It seems that data for earlier fetched articles is somehow overwritten, items are disappearing.
I've also tweaked the available settings - no help.
I'd join the earlier reviews that maintenance of this addon is lagging behind.
I like the idea to handle my RSS feeds in my web browser, I also like the looks and features of this addon, but now I am switching to another solution.

have used this for years to follow a variety of types of feeds, and it worked great until now. i especially like that i can manually drag-and-drop sort my folders and feeds, (which most other readers i've tried don't allow). it was a very good extension-based rss reader *while it was still fully functional*.

however, within the last few weeks or so, embeds in youtube feeds have stopped functioning and all return error 153.

this extension and many of nodetics' other extensions haven't been updated in multiple years (which didn't bother me until things started breaking... and still no updates came), and some reviews for some of their extensions indicate that the developers are no longer responsive to support emails. it's hard to say for absolute certain, but it seems likely that feedbro's development has been abandoned, which means that even more things - eventually important things - may break as time goes on.

for this reason, i'm lowering my review score, but will raise it again if extension development shows any signs of life in the future. with things as they are now - stuff breaking with no sign of maintenance updates - i can't recommend this extension to anyone.

youtube video player is not working!!!!!!!

Doesn't work for instagram feeds (empty)

Ebay will not work.

Ebay feeds don't load anymore. Developers are not responding either. Plugin not updated in a year either.

Stopped working with eBay a few days ago. No response from Nodetics. Looks like it's dead in the water.

Stop working for Ebay.

Comes with absolutely no instructions on how it works

"IndexDB could not be started; your Firefox profile MUST be broken..." Okay then. Moving on.

Sorry, but why is this a recommended add-on by Firefox when the source code isn't available? Your privacy policy is meaningless. Your addon requires heft permissions and we can't see - for sure, not going by your word - what it does with them. This is not the sort of thing Mozilla should be recommending. If this is a "free" add-on, but not open-source, then users should suspect they are the product being sold, not the software.
Please provide source code. I would love to revise this review.

the buttons/image links for starting the podcasts are not working. they are disabled and nowhere i can not fix that issue.
here a example page, it is for all other sites to:
https://www.tagesschau.de/inland/gesellschaft/11km-handel-kz-porzellan-100.html
i need more colors/themes and possibility to change the size of fonts.

Twitter feeds broken for 3 months already. No reaction from developers. One star.

They talk about privacy being important but yet the add on requires access to data for all web sites...explain to me how is that secure and in keeping with their privacy promise?
