IDM 642Build63 stopped working on Thursday, May 14, 2026, on Firefox 150.03, as well as on Nightly and Brave. I haven't tested it on other browsers.

Current idm '6.42 build 63' works like 70% of the time (meaning the download button shows up) on youtube on firefox 149.0 portable.
Which is better than the previous version for sure. But... not fully there yet. Keep improving it.

I really enjoy using IDM, but I'd like this plugin to have an additional feature: to allow IDM to be set to off by default, so I can only turn it on when I really need to download.

Absolute garbage now , I can't download any videos now but can download web pages which is useless to me .

افزونه IDM Integration Module نصب و استفاده راحتی داره و دانلود فایل‌ها از مرورگر رو خیلی سریع و مستقیم می‌کنه. تجربه من خیلی خوب بوده!

best of best

When i used it, it whined about "missing config files" and when i used my laptop a few days later,it lagged it sooooo hard. worst extention ever!

Even with allowing: "Show download panel for protected content which IDM may not download" it stopped working from one day to the other. Reverting to previous versions 6.41 or other older builds and so on will not fix it either.... Fix it.
